How Is Wine Made? (Correct answer)

Red wine is made from the must (pulp) of red or black grapes and fermentation occurs together with the grape skins, which give the wine its color. During this fermentation, which often takes between one and two weeks, the yeast converts most of the sugars in the grape juice into ethanol (alcohol) and carbon dioxide.

How do you make wine from home?

  • To make your very own wine, crush 16 cups of grapes or berries in a large crock. Once the crock is filled with fruit juice, add a Campden tablet to get rid of any wild yeast and bacteria. Stir in 2 cups of honey to sweeten your wine and 1 packet of yeast to help your wine ferment.

How is wine really made?

Wine making has been around for thousands of years. In its basic form, wine production is a natural process that requires very little human intervention. There are five basic stages or steps to making wine: harvesting, crushing and pressing, fermentation, clarification, and then aging and bottling.

How is wine made alcoholic?

Fermentation is probably the most critical step in wine production — it’s when alcohol is created. To trigger this chemical reaction, yeast is sometimes added into the tanks with the grapes. The added yeast converts the grape sugars into ethanol and carbon dioxide, giving the wine its alcohol content.

Is wine made from rotten grapes?

These sweet wines all have one thing in common: They are made from moldy grapes. In most cases, the sugar goes on fermenting until it is all converted into alcohol, resulting in a dry wine. You might well ask how apparently rotten, mold-encrusted grapes can be made into a delightful, lushly fruited sweet wine.

Can I make wine at home?

Winemaking is a natural process, that you can do at home, and produce a good product. The process is completely safe, and with our equipment and wine kits, you can create store quality wine at home. All of our equipment and wine kits come with great instructions and are easy to follow.

How is wine made with feet?

Grape-treading or grape-stomping (also known as pigeage) is part of the method of maceration used in traditional wine-making. Rather than being crushed in a wine press or by another mechanized method, grapes are repeatedly trampled in vats by barefoot participants to release their juices and begin fermentation.

Can grape juice become wine?

The process of fermentation in winemaking turns grape juice into an alcoholic beverage. Fermentation may be done in stainless steel tanks, which is common with many white wines like Riesling, in an open wooden vat, inside a wine barrel and inside the wine bottle itself as in the production of many sparkling wines.

Does wine have alcohol?

Whether you drink beer, wine or spirits, they all contain the same type of alcohol called ethanol. This is created when either fruits or grains are fermented to produce alcohol drinks. Liqueurs, which are also spirits-based, generally contain less alcohol and their ABV may be below 20%.

Is all wine fermented?

Firstly, and after the grapes and/or must have been placed in vats, a first fermentation takes place that is common to all wines. In this fermentation, the sugars of the grape start to turn into ethanol in an oxygen and temperature-controlled environment. This fermentation is known as “alcoholic fermentation ”.

What does wine fermentation look like?

If it’s fermenting, you will see small bubbles rising from the bottom to the top, much like a carbonated drink in a clear glass. If it’s actively fermenting, you may even see small fragments of fruit or grape pulp being thrown about in the wine.

How do grapes turn into wine?

Grape juice transforms into wine during the fermentation process. To accelerate the process, winemakers add yeast to the juice to start fermenting. The yeast interacts with the sugars in the grapes, turning the sugar into alcohol. Fermentation takes around two to three weeks to complete.

How does wine turn into vinegar?

It may look the same, but neglected, uncorked wine turns like a vampire in the night. And that’s because all wines contain bacteria which, when exposed to oxygen, start turning a wine’s sugars and alcohol into acetic acid—the stuff of the vinegar pucker.

What does noble rot do to wine?

Noble rot, also known as ‘Botrytis Cinerea’, is a fungus that attacks healthy ripe grapes. It weakens the skins of the grape which, in turn, accelerates the evaporation of the water, causing the fruit to shrivel and start to look more like a raisin.

What is Rot in wine?

Sometimes called botrytized wine or botrytis wine, noble rot wine is any wine made with grapes affected by the Botrytis cinerea fungus (aka botrytis bunch rot, grey rot, grey mold, or edelfäule in German). The affected grapes then shrivel up like raisins, concentrating the sugar content and intensifying the flavors.

What is a botrytis wine?

Abstract: Botrytized wines are wine specialties made of overripe grapes infected by Botrytis cinerea with the form “noble rot”. Botrytized wines are a distinct category of the natural sweet wines produced from withered, shriveled grapes.

How Wine is Made: From Grapes to Glass

A step-by-step visual introduction to the process of making wine, from fruit selection through bottling. The time required for each phase in the harvesting process will vary depending on the grape, the area, and the type of wine that a winemaker desires to produce. The specific steps in the harvesting process will also vary depending on the grape, the technique, and the technology used. However, the majority of the time, every wine harvest contains the following fundamental vine-to-wine procedures:

  1. This image gallery depicts the whole winemaking process, from grape harvesting through wine bottling. The specific processes in the harvesting process will vary in time, method, and technology depending on the grape, the area, and the type of wine that a winemaker desires to produce. Every wine harvest, however, contains the following fundamental vine-to-wine procedures:

Listed below is a picture guide to each of the stages involved in the production of wine, starting with picking the grapes and ending with bottling the finished product. Enjoy!

Wine Harvest 101: From Grapes to Glass

Prior to being gathered in the second week of October, 2014 in Hermann, Missouri, an indigenous red American grape named Norton was grown on the property.

1. Pick the grapes

The majority of vineyards will begin with white grapes before transitioning to red varieties. A collection of bins or lugs is used to gather the grapes, which are subsequently carried to the crushing pad. Beginning here is where the process of converting grapes into juice and ultimately into wine begins. For small wineries, hand harvesting is more labor-intensive, but it might yield greater benefits in the long run. Quinta de Leda is located in the Douro region of Portugal. Man vs. Machine (Man vs.

  • A mechanized harvester makes its way down a row of Vignoles grapes at Chandler Hill Estates, which is located in the Augusta AVA in the state of Missouri.
  • Purchase the book and receive the course!
  • With the purchase of Wine Folly: Magnum Edition, you will receive this bonus.
  • The Chardonnay harvest in Donnafugata in Sicily is now underway.
  • All of them will be eliminated in the following stage.

2. Crush the grapes

It doesn’t matter how or when the grapes were harvested; they will all be crushed in some way in the following phase. Using a destemmer, which is a piece of winemaking apparatus that does exactly what it says on the tin, the stems are removed from the clusters of grapes and the grapes are softly crushed. At the Donnafugata Winery in Sicily, these Chardonnay grapes are being processed on a sorting table before being fed into the destemmer and crusher. White grapes are placed immediately into a crusher, where they are separated from the skins and seeds, and then allowed to ferment for the whole time period.

  • All of the grapes are pressed to extract the juice and discard the grape skins, which are left behind.
  • After a time of settling, the juice is “racked,” which means it is filtered out of the settling tank and into another tank in order to ensure that all of the sediment has been removed before fermentation can begin.
  • Here’s what the juice from white grapes looks like before it goes through the fermentation process and becomes wine.
  • Red Wine:Destemmed and softly crushed red wine grapes are also widely used in the production of red wine.

The difference is that these grapes, together with their skins, are placed directly into a vat to allow the skins to begin fermenting immediately. Red grapes are being prepared for crushing and placement in fermentation tanks.

3. Fermenting Grapes into Wine

To put it another way, fermentation is the process by which sugar is converted into alcohol. There are a variety of techniques and technologies that are employed throughout this process to complement the various varieties of grapes. To keep things simple, the following are the essential components of this stage:

  • Both red and white wines: yeast is introduced to the vats in order for fermentation to take place
  • Red wines: carbon dioxide is generated during the fermentation process, causing the grape skins to float to the top of the wine. When making red wines, the grapes are pressed after the fermentation process is complete. Winemakers must punch down or pump over the “cap” multiple times a day in order to maintain the skins in touch with the juice. The reds will spend many months maturing in barrels once they have been racked to clarify the juice.

A view from above of a big fermentation tank at Quinta de Leda in Portugal, seen from the ground. Yeast nutrients are used by some winemakers to help the fermentation process along. Here’s what it looks like: a bucket filled with white grape juice, yeast, and a yeast nutrient known as Diammonium Phosphate. In order for the mixture to begin bubbling, the winemaker must wait 20-30 minutes before adding it to the fermenting wine. At Dinastia Vivanco in Rioja, the barrel aging area was filled with the rich aromas of vanilla and spice.

4. Age the wine

Once again, there are several options available to winemakers, and each one is dependent on the type of wine that is being produced. Several aspects of winemaking contribute to the intensification of flavors in a wine, including:

  • Aging over several years as opposed to aging for a few months Stainless steel aging against wood aging
  • Aging in new oak barrels vs aging in ‘neutral’ or old barrels Comparing the aging process in American oak barrels with French oak barrels barrels that have been toasted (i.e. burned by fire) at various stages of maturation

A comparison of aging in fresh oak vs neutral or old barrels; Comparing the aging process in American oak barrels to that of French oak barrels barrels that have been charred by fire at varying degrees of toastedness;

5. Bottle the wine

When a winemaker believes that a wine has attained its peak expression via age, it is ready to bottle the wine for consumption in the marketplace. The rest, as they say, is history, my friends.

  • Some white wines are ready to be bottled after only a few months in the bottle
  • Others take longer. The majority of dry red wines require 18-24 months of age before bottling

Bottling lines can be totally automated or done entirely by hand, depending on the situation. W.T. Vintners in Washington was responsible for this bottling.

How Wine Is Made: Everything You Need to Know About Winemaking

Although a few things have changed since the days of pressing grapes with bare feet, you may be surprised to hear that many ancient winemaking practices have remained unchanged. You will learn about the five fundamental phases involved in the production of wine, including how the grapes are picked, the differences in the production of red wine and white wine, and why understanding the process can help you appreciate wine even more.

Harvesting the Grapes

When it comes to the process of making wine, it all starts with the harvesting of grapes from the vine. There are several options for accomplishing this, including hiring workers to pick the grapes by hand or utilizing a grape picking machine. The method used to harvest the grapes has little effect on the final product, which is wine. Even while some may believe that picking grapes by hand helps to limit the possibility of fruit damage and improves selection, employing machines is frequently both faster and less expensive.

Because many wine areas are located in hot climates, grape harvesting is sometimes carried out at night to protect pickers from the scorching heat of the day. After the grapes have been harvested, stems and all, they are transferred to a crushing facility.

Crushing the Grapes

After the grapes have been selected and collected, they are sent through a destemmer, which is a machine that removes the stems. This apparatus (as you might have guessed) is used to destem grapes. The next section is where the differences between red, white, and rosé wines are most noticeable. In contrast to red wine and rosé wines, white winegrapes are totally crushed in a press before being pressed into wine. The skins and seeds of the grape are removed during this technique, leaving just the grape juice behind.

Red and rosé wines, on the other hand, are just lightly pressed before they are allowed to ferment.

As a result, they are fermented with their skins still on.

The Fermentation Process

Fermentation is the most important phase in the manufacture of wine since it is during this process that alcohol is produced. When yeast is put to the tanks with the grapes, it might cause a chemical reaction that is beneficial to the wine. The addition of yeast causes the grape sugars to be converted into ethanol and carbon dioxide, which results in the wine having an alcohol level. In addition to artificial colors, sweeteners, and preservatives such as sulfites, many bulk wine manufacturers may mix in other ingredients at this time, including ethanol.

  • However, this can include potentially hazardous levels of sulfate and yeast generated in a factory.
  • Wines prepared the Old-World manner, in small batches from responsibly cultivated grapes, without the use of any additions, will be found in place of those laced with secret ingredients and potentially hazardous compounds.
  • While red wine grapes are in touch with their skins for 5-14 days, rosé grapes only ferment with their skins on for a few hours, resulting in a considerably lighter color and a much shorter fermentation time.
  • While the wine is fermenting, winemakers use the open-topped jars to pound down the grape skins, allowing for more flavor to be extracted from the grape.
  • Once the white wine has been racked, the clear grape juice is fermented at a lower temperature, between 45 and 60 degrees.

The Maturation Process

When it comes to wine manufacturing, fermentation is by far the most important phase since it is during this process that alcohol is produced. When yeast is put to the tanks with the grapes, it might cause a chemical reaction to occur. The addition of yeast causes the grape sugars to be converted into ethanol and carbon dioxide, which results in the wine having an alcoholic concentration of around 13%. In addition to artificial colors, sweeteners, and preservatives such as sulfites, many bulk wine makers will blend in other ingredients at this time.

This, however, can include potentially hazardous levels of sulfate and yeast from a factory.

While red wine grapes are in touch with their skins for 5-14 days, rosé grapes only ferment with their skins on for a few hours, resulting in a considerably lighter color and a much shorter fermentation period.

While white wine is less complicated than red and rosé, it is nevertheless complex. White wine is fermented at a lower temperature, between 45 and 60 degrees Celsius, after it has been racked. It will take many weeks to finish the full fermentation process.

  • Fermentation is undoubtedly the most important phase in the winemaking process since it is during this process that alcohol is produced. Yeast is occasionally put to the tanks with the grapes in order to initiate this chemical process. The addition of yeast causes the grape sugars to be converted into ethanol and carbon dioxide, resulting in the wine having an alcohol level. Many bulk wine makers will add additional ingredients at this time, such as artificial colors, sweeteners, and preservatives such as sulphur. Winemakers are often allowed to use any natural elements they choose in their blends. However, this can include potentially hazardous levels of sulfate and yeast from a factory. Brands such as Usual Wines, on the other hand, have elected not to do so. If you’re looking for wines created the Old-World way, in small amounts from sustainably-farmed grapes without any additions, you’ve come to the right place. Red and rosé wines are produced by fermenting grapes with their skins on, which gives them their distinctive crimson hue. While red wine grapes are in touch with their skins for 5-14 days, rosé grapes only ferment with their skins on for a few hours, giving them a considerably lighter colour. Red wine is fermented in big open containers at a temperature ranging from 70 to 85 degrees Celsius. In order to extract even more flavor from the grape skins, winemakers utilize open-topped jars to pound down the grape skins while the wine is fermenting. White wine is less complicated to make than red and rosé wine. Once the white wine has been racked, the clear grape juice is fermented at a lower temperature, between 45 and 60 degrees Celsius. It takes many weeks to finish the full fermentation process.
  • The use of fresh oak barrels can provide tastes that are distinct from those produced by recycling old oak barrels. This is due to the fact that each time oak is employed, the flavor extraction decreases.
  • It is possible to obtain various tastes by using fresh oak barrels rather than recycling old oak barrels. As a result, each time it is used, the amount of oak flavor extracted decreases.

While the majority of white wines are fermented in stainless steel tanks, there are a few varieties, such as Chardonnay, that are fermented in oak barrels, similar to the way red wines are done in France. The length of time a wine must be aged is determined by the type of wine being produced. While some wines are meant to be aged for years on end, others are meant to be aged for a very short period of time—many will be available for purchase only a few months after the grapes were picked.

Fining, Bottling, and Corking

Once the wine has reached its full maturity, it is ready to be clarified, also known as “fined.” This procedure entails eliminating any undesired particles from the wine that may have caused it to seem foggy or off-color in the first place. In order to do this, winemakers use a chemical that binds to the undesired particles, making them bigger and hence large enough to pass through the filter. Fining agents are a type of chemical that is used in the manufacturing of wine. There are a few vegan choices available, such as bentonite (clay), however the most majority are derived from animal sources.

  1. (Yes, I’m talking about fish guts.) In the past, even bull’s blood was used as a flavoring agent.
  2. Even though most wines are fined, the surge in popularity of biodynamic, organic, and natural wines has led to some winemakers opting out of the practice.
  3. The wine is bottled after it has gone through the fining process.
  4. Despite the fact that this process is typically mechanized, some smaller wine makers choose to perform it by hand.
  5. While corks have traditionally been the preferred form of sealing, screw caps are becoming increasingly popular.

Appreciating How Wine Is Made

As you can see, the process of creating wine is not simple. Wine production is a time-consuming and labor-intensive process that has the potential to go horribly wrong. Harvesting and preparing the grapes requires a huge number of pickers as well as heavy, costly apparatus. A delicate science follows this, as wine makers toil diligently to crush, ferment, and develop the humble grape into one of the world’s most popular drinks, which is known as vinification. Traditional, centuries-old procedures are used by wine makers to manufacture alcohol, which is made possible by the fermentation of yeast and sugar.

Keep in mind that not every wine is made equal.

For example, many vintners may use chemicals and artificial sweeteners to boost the alcohol content of their wines and speed up the fermentation process.

Wine that is complex, excellent, and that allows the natural grape tastes to take center stage should be sought out from smaller independent winemakers or vineyards. If you enjoy merlot, raise your glass the next time you taste it and salute the winemakers of the globe.

Wine Making Process: How to Make Wine

It has been thousands of years since people have begun creating wine. When reduced to its most basic form, wine production is a natural process that requires very little involvement on the part of humans. The ingredients for making wine are all supplied by Mother Nature; it is up to humans to enhance, improve, or completely demolish what she has offered, as anybody who has had considerable wine tasting experience will attest to. Making wine involves five main phases or steps: harvesting, crushing and pressing grapes, fermenting and clarifying the juice, and finally maturing and bottling the finished product.

In reality, it is the variations and little deviations that occur at any stage in the process that provide excitement to life in general.

The methods involved in producing white wine and red wine are nearly identical, with one exception: the fermentation process.

How wine is made: an illustrated guide

It all starts with grapes on the vine: and it’s important that these are properly ripe. Not ripe enough, or too ripe, and the wine will suffer. The grapes as they are harvested contain the potential of the wine: you can make a bad wine from good grapes, but not a good wine from bad grapes.Teams of pickers head into the vineyard. This is the exciting time of year, and all winegrowers hope for good weather conditions during harvest. Bad weather can ruin things completely.Hand-picked grapes being loaded into a half-ton bin.Increasingly, grapes are being machine harvested. This is more cost-effective, and in warm regions quality can be preserved by picking at night, when it is cooler. This is much easier to do by machine.The harvester plucks the grape berries off the vine and then dumps them into bins to go to the winery. This is in Bordeaux.These are machine-picked grapes being sorted for quality.Hand-picked grapes arriving as whole bunches in the winery.Sorting hand-picked grapes for quality. Any rotten or raisined grapes, along with leaves and petioles, are removed.These sorted grapes go to a machine that removes the stems. They may also be crushed, either just a little, or completely.These are the stems that the grapes have been separated from in the destemmer.Reception area at a small winery. Here grapes are being loaded and then taken by conveyor belt to a tank, from where they are being pumped into the fermentation vessel.This is where red wine making differs from whites. Red wines are fermented on their skins, while white wines are pressed, separating juice from skins, before fermentation. This fermentation vessel – a shallow stone lagar in Portugal’s Douro region – will be filled up and then the grapes will be foot trodden, so that the juice can extract colour and other components from the skins.This is a very traditional winery, again, in the Douro. The red grapes have been foottrodden, and fermentation has begun naturally. These men are mixing up the skins and juice by hand: this process is carried out many times a day to help with extraction, and also to stop bacteria from growing on the cap of grape skins that naturally would float to the surface.Sometimes cultured yeasts are added in dried form, to give the winemaker more control over the fermentation process. But many fermentations are still carried out with wild yeasts, naturally present in the vineyard or winery.These red grapes are being fermented in a stainless steel tank. During fermentation, carbon dioxide is released so it is OK to leave the surface exposed. Sometimes, however, fermentation takes place in closed tanks with a vent to let the carbon dioxide escape.In this small tank the cap of skins is being punched down using a robotic cap plunger. In some wineries this is done by hand, using poles.An alternative to punch downs is to pump wine from the bottom of the tank back over the skins.Here, fermenting red wine is being pumped out of the tank, and then pumped back in again. The idea is to introduce oxygen in the wine to help the yeasts in their growth. At other stages in winemaking care is taken to protect wine from oxygen, but at this stage it’s needed.Once fermentation has finished, most red wines are then moved to barrels to complete their maturation. Barrels come in all shapes and sizes. Above is the most common size: 225-250 litres. The source of the oak, and whether or not the barrel has been used previously, is important in the effect it has on the developing wine.This is a much larger, older barrel, imparting virtually no oak character to the wine. This suits some wine styles better than smaller barrels.This is a basket press: once fermentation has completed and the young wine has been drained off the skins, the remaining skins and stems are pressed to extract the last of the wine that they contain.This is a bladder press, used for some reds and almost all whites. A large bladder fills with air, pressing the contents gently and evenly, with gradually increasing pressure.And this is what is left at the end – the marc. It can be used to make compost.The inside of a tank that has been used to ferment white wine: the residue consists of dead yeasts cells.Barrel halls can still look quite traditional. Cool underground cellars are perfect for maturing wines – a process that takes anything from six months to three years.Winemakers typically check the maturing red wine barrels at regular intervals, and top them up as some of the wine evaporates during the maturation process.Occasionally it is necessary to move wine from one barrel to another, or from barrel to stainless steel tank. This cellar hand is using nitrogen gas to move the wine without exposing it to large amounts of oxygen.Here wine is being moved from one barrel to another deliberately exposing it to oxygen to aid in the maturation process.Some wines see no oak at all, but are kept in stainless steel tanks to preserve the fresh fruity characteristics.Finally, the wine is ready and is prepared for bottling.

How is wine made? The ancient art of winemaking (Video)

Have you ever been curious about the process of making wine? In our most recent video, we take you step by step through the whole procedure. If you’re more of a traditionalist, don’t worry, we’ve got you covered with a video transcript embedded below. Enjoy! According to the fact that you are reading this site, it is safe to presume that you appreciate a good glass of wine on occasion. Even while most people can tell the difference between Merlot and Pinot Noir, the origins of our favorite bottle remain a total mystery to the majority of people.

That said, I can guarantee you that there’s a bit more to it than meets the eye.

How was wine made in the past?

Winemaking has a long and intriguing history, which you may read about here. The earliest evidence of this dates back as far as 6000 BC, indicating that our forefathers were likely drinking wine long before they domesticated horses. In the beginning of winemaking, it is thought that winemakers combined grapes and rice to produce fermented, alcoholic beverages. Although it is no longer popular, grapes have been pressed and juiced by human feet for thousands of years, at least until the Ancient Romans created industrial wooden presses to make wine and juice.

The fundamental processes of winemaking have remained unchanged, yet the wonders of technology have enabled winemaking to be revolutionized. Furthermore, you may be pleased to hear that contemporary winemaking is nearly entirely done without the use of toes.

1. Harvesting the grapes

Harvesting ripe grapes is the first step in the process. This activity is often carried out by machines, which shake grapes from their stems and collect them in a container. On the other side, if vineyards are steep, difficult to reach, or where labor is inexpensive, winemakers may opt to harvest by hand. Contrary to common assumption, manual harvesting has little to no impact on the overall quality of the wine produced.

2. Fermentation

This is the stage of the process where the differences between red, white, and rosé wines become apparent. Most people believe that all white wines are made from white grapes, which is not the case. However, many excellent white wines are made from black grapes, despite the popular belief. The addition of grape skins is what gives the wine its distinctive color. The crimson color of red wines and rosé wines is achieved by fermenting them while the black grape skins are still attached to the grapes.

  1. The fermentation of red wine takes place in enormous open containers.
  2. A period of five to two weeks can elapse between the time the wine is in touch with the skins and when it is not.
  3. White wines, on the other hand, are fermented without the use of skins.
  4. White and rose are best served at temperatures ranging from 12 to 22 degrees, while red is best served at temperatures ranging from 20 to 32 degrees.
  5. It is here that the yeast is introduced, which will, over time, convert the sugar present in the juice to ethanol and carbon dioxide, so providing the wine with its oh so vital alcohol content.

3. Maturation

After the juice has fermented, it is separated into different containers to let it to develop. While stainless-steel tanks are typically used for lower-cost wines, a large number of premium wines are fermented and aged in oak barrels to impart nuanced toasty-smoky flavors. The period of maturation is when the wine acquires its most nuanced flavors. If the wine is aged in ancient wood barrels, the containers are porous, allowing small quantities of oxygen to dissolve into the wine throughout the maturation process.

The length of time a wine is allowed to mature varies based on the style of wine being produced.

Some winemakers age their wines for up to five years or even longer. While certain wines are prepared specifically for early consumption — for example, some wines are available for purchase within a few months of harvest – others are not.

4. Fining and bottling

Fining is used to clarify wine, unless the wine is organic or ‘natural.’ Fining is a method that is used to clarify wine. This eliminates any undesirable particles from the wine. The majority of the time, minerals such as bentonite are used, however some firms also employ egg white or gelatine. There is no trace of the fining agent left in the bottle because it is filtered out. After that, the wine is put into bottles. And there you have it! There you have it: the entire process of making wine, from vine to bottle.

How Red Wine Is Made

Wineries now produce red wine in roughly the same way as they did 6,000 years ago in Greece and Persia, according to historians. During the winemaking process, dark-colored grapes are collected and crushed before being fermented, stirred, and separated from their skins by a press. Voila! Red wine.While improved containers, presses, and cellars have significantly improved the quality and efficiency of red wine production, the process is still substantially the same as it was decades ago. Apart from grapes, yeast, and, in most cases, sulfur dioxide as a preservative, no other ingredients or heating are required in the manufacture of red wine.

Red wine is made on the skins

Red wine is manufactured in the same way as white wine, with one significant distinction. In most cases, the skins and juice of the grapes are blended in a tank or vat throughout the fermentation process. In order to separate the juice from the skins of white wines, they are pressed before to fermentation. Color, taste, and textural elements are incorporated into the juice during the red wine manufacturing process, whereas the yeast converts sugar to alcohol during the process of making white wine.

Eric DeFreitas created this infographic.

Harvesting red-wine grapes and the crush

Grapes for red wine are ready to be harvested in late summer to early fall, many weeks after the original green hue of the grapes has changed to a dark crimson or blue-black tint, a process known as veraison. Vineyard personnel remove the grape bunches or clusters from the vines, which is done by hand. Winemakers can also sort out mildewed grapes, undesired raisins, leaves, and debris after the grapes have been delivered to the winery. This can be done by hand or using a self-propelled equipment, which shakes or slaps the grapes off their stems and gathers the individual berries and juice.

Free run is the term used to describe any juice produced during these phases prior to pressing.

The Wine Enthusiast team has received your email address and will be in touch shortly with unique deals and news from the company.

Privacy PolicyMany winemakers often administer a calibrated dosage of sulfur dioxide at this stage, as well as afterwards, to kill undesired bacteria and limit oxidation.

Red wine fermentation and pressing

Must is the term used to describe the mixture of juice, skins, and seeds. A procedure known as cold soaking is used by some winemakers to chill the must for a day or two before fermenting it in order to remove color and taste ingredients from the skins before any alcohol is produced. Afterwards, some winemakers initiate the fermentation process by adding commercial yeast, while others let the native yeast that clings to the grapes or resides in the cellar’s environment to do so. It doesn’t matter which method you use, yeast cells spring to life in the sweet solution and start converting the sugar into alcohol, heat, and carbon dioxide.

  1. This cap must be mixed back into the juice at least once per day, if not more frequently, during the fermentation phase in order to maintain it wet during the fermentation process.
  2. It also helps to regulate heat, which may reach temperatures of over 100 degrees Fahrenheit if not properly monitored.
  3. You may either pump liquid over the cap or punch it down.
  4. Transferring the must into wine presses allows winemakers to separate the skins and seeds from the wine, as well as compress the skins to extract what is known as pressed wine from the wine.
  5. If you work it too hard, it will bring out bitter tannins.

Red wines typically mature in oak barrels

Almost all red wines must be aged for a period of time before they can be bottled and sold. In large tanks, the process might take anything from a few months to many years, although oak barrels and vats are favoured for producing high-quality, traditional-style red wines. Malolactic fermentation happens most often during the wine’s aging phase, and it is responsible for converting the wine’s sour malic acid into softer lactic acid. It can occur spontaneously, but the winemaker can actively stimulate it by introducing a malolactic culture to the fermenting wine.

  1. New barrels provide more powerful spicy smells and increased flavors, whereas neutral vessels, such as barrels that have been used previously or containers made of concrete or clay, are regarded mostly for their ability to smooth out the texture of a wine’s mouthfeel and mouthfeel.
  2. American white oak barrels, on the other hand, are preferred for many wines because of their rich vanilla and coconut notes.
  3. As red wine matures, sediments such as yeast cells that have died and small particles of grape skins settle to the bottom of the bottle.
  4. Storage is the technique of removing sediment from wine after it has been clarified by pumping or siphoning it off the sediment.
  5. It makes use of the binding characteristics of egg whites, isinglass, and bentonite clay to make red wines taste less tannic and appear less hazy.

These agents collect undesirable chemicals, which are then deposited at the bottom of the tank or barrel. When it comes to making red wine, blending is a vital stage. By combining wine from various barrels and tanks, the winemaker may achieve greater complexity and perfect balance. Getty

Filtration and bottling

When a red wine has reached the point of maturity when it can be bottled, many winemakers choose to filter it first. Extra sediment is removed using coarse filtering. A sterile filtration eliminates practically all of the leftover yeast as well as germs that might potentially ruin the wine later on in the process. Often, the final correction of sulfur dioxide is accomplished right before a wine is packaged for sale. This is the procedure that has evolved the most from the beginning of humanity, when gourds, goatskins, and clay jars were the most advanced packing materials available to mankind.

Today’s winemakers have a plethora of alternatives, techniques, and technology at their disposal compared to their forefathers.

Learn How Wine Goes From Vine to Bottle

It is during fermentation that the sugars in the grape are transformed to alcohol and carbon dioxide, as well as a significant amount of residual heat, which must be regulated to avoid taste distortion. The fermentation of red wine is normally carried out in stainless steel tanks, big vats, or oak barrels, depending on the kind of wine.

Generally speaking, the more contact the red wine grapes have with their grape skins, the “larger” the wine will likely be.

Chardonnay is an exception; some winemakers choose to ferment Chardonnay juice in sealed oak barrels in order to influence the development of the taste profile.

Similarly, if the acidity of the must is low, acid can be added to raise the acidity; this is known to as “acidification.” It is also necessary to perform an additional step known as “stirring the lees” during the white wine fermentation.

This stage consists of combining the remaining yeast that has remained after fermentation in order to produce extra tastes.

How is wine made?

Nowadays, people from all around the world have joined together to exchange skills and learn about new ones. Wine has never tasted better than it does right now! But what are the fundamentals? What is it that transforms these seemingly innocuous grapes into bottles of sharp reds or crisp whites that are so refreshing? With each sort of brand providing a unique taste, we wine enthusiasts may enjoy a wide variety of wines.

Pick the grapes

  • Although this may appear to be the simplest task when it comes to wine production, there is a significant amount of thinking that goes into it. Due to the fact that the flavor of a grape changes depending on when it is picked, the acidity, sweetness, and flavour of the grape are also all influenced. Depending on the size of the vineyards, the grapes can be harvested by hand or by machine, depending on the variety. In addition, if picking is required during hotter days, night picking may be substituted in order to boost efficiency.

Crush the grapes

  • They will always be crushed, no matter what type of wine or grape is being used. The destemmer machine, which is simply a machine that eliminates the stems and parts you don’t want while crushing the grapes into liquid mush, is commonly utilized for the majority of wines these days. The skins and seeds of white wine grapes are removed in order to eliminate any color that may have leaked into the liquid, but the skin of red wine grapes is left on.


  • The fermentation process is the next stage on the list, and it is this phase that will determine the final flavor. The sugar in the combination is converted into alcohol, and a variety of procedures are used to pair it with different types of grapes to produce diverse flavors. The most natural method is to just add yeast and let it to ferment naturally over time. Carbon dioxide is generated during the fermentation of red wines, which are typically fermented at higher temperatures than white wines. The red wine process is often carried out until all of the sugar has been converted to alcohol, resulting in a dry wine. Even while white wines can be fermented until they are completely dry, the sweet wine varietals are stopped before all of the sugar is transformed, resulting in a sweeter and less alcoholic drop overall. There is even the potential that grapes will be squeezed even after fermentation to increase the amount of rich smoothness in the wine.

Age the wine

  • The process of aging might differ depending on the time, place, and circumstances. It is possible to age wines in stainless steel or oak barrels for a period ranging from a few months to several years. The barrels used can be either new oak, neutral wood, American oak, or French oak. There are even different amounts of ‘toasting,’ which is the process of the barrel being scorched by fire, which can make a difference. In general, the flavor of a wine can get more powerful over time

Bottle the wine

  • Prior to bottling, the wine is subjected to a filtering procedure, which eliminates any undesired particles that may have remained in the liquid during the fermentation process. It is now time to bottle the wine, which will take place after this. Nowadays, this is mainly accomplished by mechanical means. After the wine bottle has been progressively filled to the top, the winemakers will inject a little amount of nitrogen or carbon dioxide into the bottle to displace any oxygen that may have accumulated above the fill line. We have everything sealed and ready to go on sale.

What exactly is “natural” wine?

After moving to Paris in the 1990s to study French literature and movies, Jenny Lefcourt and her friends discovered a new variety of wine that they enjoyed drinking a lot more than the others. She recalls that this wine tasted “completely different, and alive, and exquisite,” as she put it. Later, they stumbled onto a taste of the wine offered at one of the neighboring restaurants, which was a pleasant surprise. “It didn’t have a name at the time,” she says, but it was the product that we’ll now refer to as natural wine, and she began importing it in 2000, when she was just starting out.

  1. The industry has evolved into a source of indie social capital, with wine labels that are as closely followed and obsessively collected as album covers were in the ’80s.
  2. Moreover, it has been the topic of passionate dispute in the wine industry, with natural wine purists advocating for its virtues and exhilarating flavor, while traditionalists criticize the perceived defects and even the idealism of natural wine.
  3. However, the history of sulfites makes this difficult to determine; some individuals believe that sulfites, in one form or another, were employed to preserve wine as far back as the seventh century BC.
  4. “People assume that natural wine is a new thing, but it’s the traditional method to create wine,” she says.
  5. Discover what natural wine is, how we became disenchanted with it — and then reconciled with it — and where it’s headed next.

What it is

Nature-based wines are more of a notion than they are a clearly defined category with widely accepted features. A wine created only from unadulterated fermented grape juice and nothing else is what it is in its purest form. Many individuals — winemakers, distributors, journalists, and sommeliers — are uncomfortable with the phrase “natural wine,” which refers to wine produced without the use of chemicals. Some people prefer the terms “low-intervention” wine, “naked” wine, or “raw” wine instead of “low-intervention.” “It’s simply fucking fermenting juice,” Scruggs describes her product as.

  • The following essay is written with the assumption that natural wine is not a fake and that its advocates are not crazy, but rather that it is a hotly discussed and endlessly difficult issue that never fails to elicit passionate responses from a wide range of people.
  • Grasp natural wine necessitates a fundamental understanding of the winemaking process, which is often difficult.
  • Natural wine, on the other hand, is produced from grapes that have not been treated with pesticides or herbicides.
  • When it comes to turning those handpicked grapes into juice, natural winemakers rely on native yeast, which is the stuff that’s whizzing around in the air and will land on grapes if you leave them in a vat for a long enough period of time, to kickstart natural fermentation.
  • And, in contrast to the majority of traditional winemakers, they do not utilize any chemicals (such as false oak taste, sugar, acid, egg white, or other additions) throughout the winemaking procedure.
  • Some natural winemakers may use a small amount of sulfites on occasion.
  • Natural winemakers either do not use sulfites at all or use them in very small amounts, whereas conventional winemakers use up to ten times as much as natural winemakers.

The purest of the pure — organically fermented grape juice that contains no sulfites — is referred to as “zero-zero,” which refers to the absence of any additional ingredients.

It is typically regarded permissible in natural wine circles to add small amounts of sulfites at the bottling stage (between 10 and 35 parts per million), which are generally thought to be between 10 and 35 parts per million.

In the United States, the maximum allowed concentration is 350 parts per million.

However, this is not always the case.

In Scruggs’ opinion, “there’s a common misperception that natural wine is one thing – that it has a “funky” or “unclean” taste.” In my opinion, this is an injustice.

According to Pascaline Lepeltier, a long-time natural wine advocate, “Whatever you prefer as a more conventional wine consumer, you can find an alternative wherever in the globe.” Lastly, there’s glou-glou, a popular form of natural wine that’s meant to be consumed without having to worry about what you’re drinking.

What it isn’t

Winemaking that is considered “conventional” — often known as “non-natural” winemaking — is defined by the use of technology. When it comes to the vineyard, pesticides and herbicides are used to get the desired results. Laboratory-grown yeast (to control fermentation and taste), acid (to boost the wine’s acidity, which in turn might help the wine age more gracefully), and sulfites (added at the time of bottling) are the most common forms of intervention in the cellar (to preserve flavor). Many winemakers also use sugar, which does not make the wine sweeter, but rather gives the impression of having “body” since it turns into alcohol when exposed to heat.

According to Lefcourt, owner of JennyFrancois Selections, “a lot of wine is a grape product, plus all of these millions of additives to make a product that is reliably the same every year.” “It’s similar to Coca-Cola.” Clarifying wine with egg white and isinglass, which is manufactured from fish bladders, is a common practice that results in many bottles being non-vegan despite the fact that they are not labeled as such.

Marcel Lapierre is a French winemaker who specializes in “natural” Beaujolais wines.

Technological advancements are the most significant element in this transformation: Pesticides began widely used following World War II, when troops sprayed their sleeping bags with DDT to prevent the spread of sickness; commercial yeast first appeared on the market in the mid-’60s, and now it is used in a variety of applications.

  • We owe a debt of gratitude to American wine critic Robert Parker, who in the 1980s devised a 100-point wine rating system.
  • As Parker’s reputation grew, his ratings began to have a substantial impact on wine sales.
  • The homogeneity of what people considered to be good wine began to take place when this began to happen, according to Lefcourt.
  • This goes to the heart of a long-running discussion between natural wine devotees and others who believe they have gone off the rails: Is the “best” wine produced with the least amount of intervention?

Or is it produced by seasoned, well-informed winemakers who are striving to create a specific outcome that is representative of their region and traditions? This discussion is unlikely to come to a halt anytime soon.

Where it came from, and where it’s going

The majority of people believe that the present natural wine movement got its start in rural France, when a small group of low-intervention winemakers who had been toiling (and tilling) in their own organic bubbles became acquainted with one another and began to form a social network. “These were natural winemakers who were isolated in their appellations, perhaps the only ones there working organically in the vines with little to no additives in the cellar,” Lefcourt recalls. “These were natural winemakers who were isolated in their appellations, perhaps the only ones there working organically in the vines with little to no additives in the cellar.” Lefcourt recalls that La Dive Bouteille, which began in 1999 with 15 wineries and around 100 guests, was one of the first planned and official natural wine tastings in the world.

The collaboration between Karl-Josef Hildenbrand and the film industry courtesy of Getty Images Importers of natural wines such as Lefcourt and Louis/Dressner expanded and gained popularity in the United States during the 1990s and 2000s.

“There was a lot of talking to deaf ears,” recalls Lefcourt, “trying to communicate and create understanding in those early days.” Alice Feiring, one of the media’s early proponents of the natural wine movement, wrote her first report for the Times in 2001, exposing the mad scientist-like machinations of conventional wine; in 2005, she covered the natural wine bar trend in Paris, among other things.

  • The natural winemaking method of focusing on local grape varietals — rather than cultivating varietals to adapt to market trends — can make those plants more immune to the impacts of climate change, according to Scruggs.
  • A holistic, chemical-free farming approach that considers the farm’s ecology as well as moon cycles, biodynamic farming is becoming increasingly popular.
  • The fact that many winemakers who pay for organic certification would subsequently utilize additives — such as large doses of sulfur, yeast, acid, and so on — while creating their wine further complicates the situation.

At this point, we get to one of the most significant barriers standing in the way of consumers enjoying the experience of drinking natural, minimally-intervention, organically grown wine: it might be difficult to recognize at first glance.

At this point, we get to one of the most significant barriers standing in the way of consumers enjoying the benefits of drinking natural, minimally-intervention, organically produced wine: it might be difficult to detect at first glance.

wine – The wine-making process

It is preferable to use fresh and completely matured wine grapes as the raw material for wine production. It may be necessary to harvest grapes before they reach full maturity in chilly locations such as northern Europe and the eastern United States, due to a lack of adequate heat to cause ripening. Alternatively, the sugar shortage can be remedied either directly with sugar or indirectly using grape juice concentrate. Because of natural moisture loss (partial raisining, as in the production ofMálagawines in Spain), grapes that are allowed to reach full maturity on the vine or that are partially dried by exposure to sunlight after harvesting have a high sugar content as a result of natural moisture loss (partial raisining).

  3. Top left: Red and white grapes used to make white wines are crushed in a horizontal press.
  4. Top right: Crushed grapes for red and rosé wines are placed directly into fermenting vats with their skins, a process known as skin contact fermentation.
  5. is a publishing company that publishes encyclopedias.
  6. When grapes are harvested too early or too late, they become thin and low in alcohol; when grapes are harvested too late, they become rich in alcohol but low in acidity.
  7. It is necessary to harvest the grape clusters off of the vine and place them in buckets or boxes before transferring them to bigger containers (huge tubs in Europe, metal gondola trucks in California and elsewhere) for delivery to the winery.
  8. Grapes can be dropped directly into the crusher at the winery, or they can be discharged into a sump and transported to the crusher by a continuous conveyor system.


Crushing and stemming the grapes are commonly done at the same time in modern automated wine production using a crusher-stemmer, which is typically comprised of a perforated cylindrical device with a series of paddles that rotates at a speed of 600 to 1,200 revolutions per minute. The grape berries are crushed and fall through the holes in the cylinder, with the majority of the stems exiting out the other end of the cylinder. It is also possible to utilize a roller-crusher. Crushing with the feet and treading with shoes are ancient practices that are no longer used.

It is possible that full red grapes will be placed into tanks, which will then be sealed.

Malicacid also undergoes some intracellular respiration, which is beneficial. Due to the slowness of the respiration process, wines produced in warm climates may be pale in color, have low acidity, and have an unique odor.

Juice separation

When white grape juice is processed, or when white wine is sought, the juice is normally separated from the skins and seeds as soon as the grapes are crushed to prevent fermentation. When flavor extraction is desired, the white skins may be left to remain in contact with the juice for 12 to 24 hours. However, this process promotes color extraction, which might be undesirable in some cases. Separating the juice from the solids is accomplished through the use of two primary techniques. By placing the crushed grapes in a container with a false bottom and, in certain cases, artificial sides, it is possible to drain out a significant amount of juice.

  1. The crushed grapes are usually placed in a apress, which is more prevalent.
  2. Continuous screw-type presses are also used, particularly for drained pulp, and are very effective.
  3. It is necessary to feed the crushed grapes into the cylinder before inflating the tube, which presses them against the revolving cylinder walls and forces the juice out through the holes.
  4. Continuous presses are particularly useful for the manufacture of red wines, in which the skins, seeds, and juice are all fermented simultaneously in the same vessel.
  5. As a result, the amount of free run juice collected is significantly more than that produced from unfermented musts.
  6. In white or red fermentations, the drainedpomace (crushed mass left over after extraction of the juice from the grapes) is used to make distillation material for the manufacturing of wine spirits.
  7. The pomace can be further processed by being washed and pressed, or it can be distilled directly in special distillation stills.

Must treatment

In order to facilitate separation of the suspended elements in white musts, settling is typically required after the must has been harvested. Measures such as the injection of sulfur dioxide before to settling and the lowering of the temperature during settling aid in the prevention of fermentation and the normal settling of the suspended material. Many wineries centrifuge the white must to remove the particles, which is common in many regions. Circular motion is used to generate a powerful pulling force throughout this operation.

It is rare to see the addition of pectin-splitting enzymes to musts in order to ease pressing.

Prefermentation heat treatment of red musts to remove color and deactivate enzymes has rekindled attention in the winemaking community.
