Added sulfites preserve freshness and protect wine from oxidation, and unwanted bacteria and yeasts. The FDA estimates that less than 1% of the U.S. population has a sulfite allergy, and those who do are most likely asthmatic.
Which wine has the most sulfites?
- In fact, white wine usually has more sulfites than red wine. Sulfites are created naturally during the fermentation process. After a wine has fermented it usually contains somewhere between 2 and 10 parts per million (ppm).

Do you have to add sulfites to wine?
Adding sulfites to homemade wine is important and highly recommended. It’s like buying insurance for making a wine that doesn’t spoil or oxidize. If you do not add sulfites you can make wine successfully, but most will find it hard for the wine to keep over extended periods of time without refrigeration.
What wine has no sulfites?
Top 5: Wines Without Sulfites
- Frey Vineyards Natural Red NV, California ($9)
- Cascina Degli Ulivi Filagnotti 2009, Piedmont ($22)
- Domaine Valentin Zusslin Crémant Brut Zéro, Alsace ($25)
- Donkey & Goat The Prospector Mourvèdre 2010 ($30), California.
- Château Le Puy Côtes de Francs 2006, Bordeaux ($42)
Why do you remove sulfites from wine?
You’ll end up with a fresher-tasting glass—and removing sulfites may even help with congestion or flushed skin. If you’ve ever woken up with cement mixer head from one glass of vino too many, you might have thought it was due to sulfites.
How long will wine last without sulfites?
Without sulfites (either naturally occurring or added), most wine wouldn’t last much longer than six months. With sulfites, wine keeps almost indefinitely. Sulfites also prevent browning in wine by reacting with oxygen in the sealed bottle of wine.
What alcohol is high in sulfites?
Beer, brown liquor, and ciders are high in histamines and sulfites, so stick to natural wines and clear liquors.
Are sulfites in wine harmful?
Are Sulfites Harmful? Consumption of sulfites is generally harmless, unless you suffer from severe asthma or do not have the particular enzymes necessary to break down sulfites in your body. The FDA estimates that less than 1% of the U.S. population is sulfite-sensitive, so it is relatively rare.
Does wine in Italy contain sulfites?
Sulfites are a naturally occurring byproduct of wine, and sometimes winemakers choose to add additional sulfites to prevent a wine from spoiling. Wines sold in the United States have the “contains sulfites” note on wine labels, but wines sold in Italy do not, simply because labeling laws differ from country to country.
Does red wine contain more sulfites?
While all wine contains some level of sulfites, the prevailing myth has been that red wine has more sulfites than white wine. But the science doesn’t hold. This results in a higher amount of tannins, which act as a natural antioxidant that protects the wine from bacteria. As such, less sulfur dioxide is required.
Can you get rid of sulfites in wine?
In theory, you can remove sulfites by adding hydrogen peroxide to your wine.
Do more expensive wines have less sulfites?
Wines with lower acidity need more sulfites than higher acidity wines. Wines with more color (i.e., red wines) tend to need less sulfites than clear wines (i.e., white wines). A typical dry white wine may have around 100 mg/L whereas a typical dry red wine will have around 50–75 mg/L.
What is the difference between sulfites and sulfates?
Both sulfates and sulfites are sulfur-based compounds. Sulfates are salts of sulfuric acid, and you probably encounter them on a daily basis. Sulfites are naturally occurring compounds found in all wines; they act as a preservative by inhibiting microbial growth.
Is Cloudy wine OK to drink?
It is almost always safe to drink a cloudy wine, unless the sediment is the result of a bacterial infection, in which case your wine will smell bad enough that you don’t want to drink it anyway. Sediment in wine is not hazardous and does not usually affect the flavor.
What foods are high in sulfites?
Examples of foods that may contain sulfites include:
- Baked goods.
- Soup mixes.
- Canned vegetables.
- Pickled foods.
- Dried fruit.
- Potato chips.
Do European wines have less sulfites?
The truth is that European wines typically contain the same sulfite levels as American wines. The difference is that Europe doesn’t have a law requiring wineries to place a sulfite warning on their labels.
Why You Shouldn’t Worry About Sulfites in Wine
Sulfites are one of many components of wine and winemaking that are misunderstood, but few are misinterpreted as openly or as viciously as they are with sulfites. In the eyes of the daytime television doctor crowd, sulfites are the Severus Snapes of wine; yet, when used properly, they are essential to success and will not kill you or Harry Potter, despite popular perception. And, despite the fact that it took seven novels to fully comprehend Snape, give me five minutes and I can explain what you, a person who consumes a lot of wine, truly needs to know about sulfites.
Added Sulfites: Which Is Better?
Natural sulfites are exactly what they sound like: completely natural substances formed during fermentation.
While I understand what your sage-burning, hippy friend told you, please accept my apologies for not having consumed a 2009 sulfite-free wine in Topanga Canyon.
- It is literally, utterly, and completely impossible.
- You expect to be able to just consume a wine that has been hanging about for 50 years?
- Sulfites, which are added to retain freshness and prevent wine against oxidation, as well as undesirable bacteria and yeasts, are beneficial.
- WineSpeed is a weekly wine report written by Karen MacNeil, author of The Wine Bible and editor of the weekly wine report WineSpeed.
- “Sulfur is an anti-microbial agent found in nature.
- Courtesy of Frey Photography Thanks to Frey for his contribution.
- Believe me when I say that I understand the desire to lay the blame for your wine headaches on something other than the fact that you’re consuming too much alcohol.
According to the Food and Drug Administration, fewer than one percent of the population in the United States has a sulfite allergy, and those who do are most often asthmatic.
If you have asthma, you should carry an Asthma rescue inhaler with you at all times because an order of shrimp has more sulfite than a full bottle of Sangiovese.
If you have a history of allergies, such as hay fever, you might want to try Claritin first before reaching for the bottle—but proceed with extreme caution or with a designated driver in tow.
And, no, sulfites aren’t generally harmful to your health.
Anti-alcohol advocates began attempting to pass laws in the 1970s that would force wine labels to declare the substances they had in them.
However, this has absolutely nothing to do with genuine health hazards and was created only to frighten people away from consuming wine in the first place.
Yes, your child’s fruit leather has more sulfites than a glass of red wine.
Likewise, those French fries you consumed at lunch have a purpose.
However, you shouldn’t be concerned about it.
The reason that sulfites became such a huge concern was that there was an increase in sulfur allergy responses in the 1980s, which was attributed to the enormous quantity of sulfur used in preservatives.
The fact that you would want firms to declare that peanuts are present in their products makes reasonable, but it doesn’t follow that you, as someone who is not allergic to peanuts, must spend the rest of your life frightened of every Chex party mix.
Dude, spend your life with enough of booze in your possession.
There are hundreds of sugars, added yeasts, gelatin, and other undesirable ingredients in wine that are not required to be disclosed.
These wines are made with as little chemicals as possible, with a preference for natural sugars and yeasts, and are frequently “sans soufre” (without sulfur) (without sulfur).
In addition, for those of you who still believe that your wine headaches are caused by sulfite, these wines are just what the doctor ordered. And by “doctor,” I mean “Me, Marissa A. Ross, Professional Wine Drinker who no longer gets headaches, just trust me on this,” as in “Just believe me on this.”
Solving the Sulfite Puzzle
At the time I began producing wine at home, I knew the role and necessity of sulfite in wine preservation, but I never received the same response again when I inquired about how much sulfite should be added to the wine. To some, sulfuric acid additions appeared to be witchcraft rather than being based on well-established scientific concepts. Today, many amateur winemakers are confused about the usage of sulfite or avoid the activity altogether because they believe sulfite is an environmentally damaging chemical.
In the winemaking industry, sulfite is the most effective and extensively used preservative.
It helps to keep the wine’s freshness and color while maturing it, and it is crucial for aging wines to keep them fresh and vibrant.
Consider the following examples of fundamental chemistry in order to demystify sulfite: This will assist us in better understanding how sulfite preserves wine and how much “free SO2” we are adding into our wine production process.
What Is Free SO 2?
Chemistry-derived from elemental sulfur are the most effective preservatives and sanitizers used in winemaking, and they are also the most expensive. Sulfur dioxide (SO 2) gas, which is produced by the combustion of sulfur, has been employed to preserve oak barrels against microbial decomposition from the beginning of winemaking history. This method of storing empty barrels for a long length of time is still extensively employed in the winemaking industry today. A sulfite solution with high antibacterial qualities may be made by condensing SO 2gas to form a colorless liquid and then evaporating it.
Additionally, free SO 2can be discovered in the musts of crushed grapes that have been treated with sulfur-based insecticides throughout their growing process.
Both free SO 2 and total SO 2 (the sum of free and bound SO 2) are extensively used in commercial winemaking, and both are useful metrics.
The term “molecular SO 2” should be studied in depth if you wish to grasp the chemistry of free SO 2.
The active component of free SO 2 is molecule SO 2, and the efficacy of molecule SO 2 is depending on the pH of the wine. The concentrations of SO 2 are reported in milligrams per liter (mg/L) (milligrams per liter). One mg/L is equal to one part per million (ppm) (part per million).
Measuring Free SO2
The issue for the home winemaker is to accurately measure the all-important free SO 2concentration. For measuring free SO 2concentration in the 0 to 100 mg/L range, CHEMetrics provides Ripper-method titration cells that are offered under the brand name Titrets and are available at most home winemaking supply shops. The results for dry white wines are satisfactory, despite the fact that they might have an error margin of up to 10 mg/L. For red wines or white wines containing ascorbic acid or tannin, the results are less consistent; nonetheless, they are sufficient for home winemaking purposes.
- An ampoule holding a reagent (iodide-iodide titrant in phosphoric acid solution and a starch indicator) and a valve assembly are included in each Titrets.
- Because the reagent is enclosed under vacuum, the shelf life of the titration cells is virtually limitless.
- The valve assembly is placed over the ampoule in order to measure free SO 2 using Titrets technology.
- When the wine comes into contact with the reagent, it changes color to a deep blue.
- In the latter case, the color shift is difficult to detect.
- Another technique that may be used to increase color change detection in red wines is to dilute the wine sample by a factor of 50, for instance.
- The real concentration of the wine is 40 mg/L if the wine is diluted to 50 percent and a free SO 2 reading of 20 mg/L is obtained, as an example.
Sources of Sulfite
When it comes to winemaking, the term “sulfite” refers to either the white (sulfurous acid salt) powder that is employed in the preparation of a sulfite solution, the sulfite solution itself, or the free sulfur dioxide (SO 2) found in musts and wines. Sulfite is accessible in two popular powder forms: potassium metabisulfite and sodium metabisulfite. Both of these compounds are toxic. Sodium metabisulfite is a preservative that may be used to clean winemaking equipment and to extend the shelf life of musts and wines.
- In either powder or Campden tablet form, potassium metabisulfite can be obtained.
- (Campden pills are available in a variety of sizes and dosages, so be sure to double-check before you buy.) Prior to dissolving in water, it is necessary to crush the tablets into a fine powder.
- In addition to potassium metabisulfite, there are additional compounds available on the market that can be used in various goods.
- Such items are convenient if you wish to add all of the listed compounds in the exact amounts and proportions that are specified.
- – One advantage of tablets is that they may be packaged in conventional amounts, such as 54-liter demijohns, which makes transportation easier.
- It is usually preferable to add substances one at a time in the appropriate proportions in order to properly control chemical additions.
- Potassium metabisulfite and Campden tablets contain roughly 57 percent and 48 percent sulfur dioxide, respectively, in their composition.
This implies that when a solution is made and put to wine, approximately half of the sulfite really becomes free SO 2 as a result of the reaction. This is critical to understand since it is commonly assumed that the full quantity of sulfite in the wine preserves the wine.
Sulfite as Preservative
A minimum free SO 2concentration should always be present in order to adequately preserve wine, although the concentration should not exceed the nominal amounts specified. The amount of sulfite in the wine should be sufficient to preserve it from microbial decomposition, but not so much that it can be recognized when drinking it is ideal. The presence of sulfite in the wine’s flavor or aroma is considered a major flaw. Before you may add sulfite to must or wine, you must first establish the present free SO 2concentration in the mixture.
- If the level of free SO 2 in the wine is already high, this might cause issues.
- It is important to note that free SO 2 may already be present in juice (since producers add sulfite prior to shipment to prevent spoiling) and concentrates, as well as juice from freshly crushed or pressed grapes (which contains sulfite).
- The amount you use is determined by how much sulfite you desire and the quality of the grapes used.
- Second, decide ahead of time what style of wine you want to create and what vinification procedures you will be employing, and then plan your sulfite additions in accordance with your preferences and needs.
- When it comes to alcoholic fermentation, what kind of yeast will you be using?
- A malolactic fermentation (ML) is a type of fermentation in which the harsher malic acid is converted into the less harsh lactic acid.
- The presence of very high quantities of free SO 2 might result in fermentation that is slow or even stops completely.
How to Add Sulfite
When adding sulfite to must or wine, the easiest and most successful method is to first prepare a 10 percent solution and then add the needed incremental quantity according to the chart below. Using a little amount of warm water (it does not dissolve well in cold water), produce the 10 percent solution, then top it up with cool water to reach the desired concentration of 100 milliliters (mL). Make use of a tiny, affordable scale to determine the amount of sulfite powder that will be needed. You may also use measuring spoons instead of measuring cups because 1 mL of powder weights around 1 g, which is plenty for amateur winemaking.
- This results in a ten percent mistake, which is exacerbated by the inaccuracy of measuring spoons used in the process.
- Consider the following scenario: if your wine contains 10 mg/L of free SO 2 before to bottling and you want 50 mg/L to safeguard the wine, you’ll need 40 mg/L.
- When utilizing sulfite powder or Campden tablets rather of a 10 percent solution, you will require 40 mg/L x 19L / 1000mg/g x 0.57 = 1.3 g of powder or three 0.44-g Campden pills to get the desired result.
- If you bottle your wine within a year after the prior sulfite addition, the free SO 2level will most likely be quite near to the level of the previous sulfite addition unless the wine has been subjected to several rackings and excessive air exposure.
- Always remember to add sulfite to wine prior to racking in order to preserve the wine from aeration during the racking process.
- The wine should be properly stirred after each sulfite addition.
- What happens if you have an excessive amount of free SO 2 in your wine, and you can detect it?
- The goal is to keep the free SO 2 concentration below 50 mg/L.
- Step 3: This is perfectly OK because the wine is extremely well protected, and the aeration will cause some free SO 2 to disperse as well.
After 2 or 3 rackings, take a free SO 2reading, and repeat the process until the free SO 2concentration approaches the required level of concentration. Before bottling, let the wine to rest for a couple of months to allow the flavors to blend.
Free SO 2and pH
The pH of a wine has an effect on the concentration of free SO 2 in it, and this must be taken into consideration when adding sulfite. The efficiency of SO 2 is substantially diminished at high pH (low acidity), and the wine is consequently less effectively protected against oxidative effects and microorganisms that might damage the wine at high pH (low acidity). When making sweet wines, you should aim for a free SO 2 concentration that is roughly 25 percent greater for every 0.1 pH increase over 3.2 (for sweet wines), 3.4 (for white wines), and 3.6 (for sparkling wines) (for red wines).
Remember to make up for any free SO 2 that may have been present.
Ascorbic acid (vitamin C) possesses anti-oxidant qualities that make it an excellent preservative, particularly for white wines, where it helps to maintain the color. However, it should only be used in combination with sulfite in order to maximize the efficiency of the sulfite solution, and not alone. Because ascorbic acid lowers the pH of the sulfite solution, the effectiveness of the treatment is boosted. Ascorbic acid should never be used without the addition of sulfite or without the presence of the specified minimum quantity of free SO 2, since this will actually promote oxidation.
In order to prevent imparting an off-taste to the wine, the dosage should never exceed 10 g/hL.
Sulfite and Oak
For preserving old oak barrels for a lengthy period of time, sulfite is a good alternative to bleach. Using a sulfur-citric holding solution made from 2 g of potassium metabisulfite and 1 g of citric acid for each liter of barrel volume can help to maintain sterility and keep the barrel smelling sweet.First, fill the barrel two-thirds of the way with cold water to start the process. To make the holding solution, dissolve the sulfite and citric acid in warm water in a small glass container and set it aside for later use.
Remember to top out the barrel with fresh water or extra holding solution once a month to keep it running smoothly.
The use of a holding solution is not suggested for new barrels or barrels less than one year old since the oak extract will be taken away during the process of cleaning.
This will prevent any bacteria or mold from growing.
Sulfite to Sanitize
The goal of sanitizing winemaking equipment is to eliminate germs and avoid microbial deterioration in the winemaking process itself. It is impossible to overstate the importance of sanitization. Initial difficulties are encountered, but once a routine is established, the technique becomes second nature. Prepare a sulfite solution for disinfecting winemaking equipment by dissolving 3 tablespoons of sulfite powder in roughly 1 liter (1/4 gallon) of warm water until completely dissolved. Close the container and shake it firmly to ensure that the powder is thoroughly dissolved.
- The container should be well-stopped at all times, and the sulfite solution should be utilized within a few months of being stored there.
- In order to boost the efficiency of the sulfite solution, an equivalent amount of citric acid (3 tablespoons) can be added to it.
- It is necessary to allow the solution to reach the full surface of the equipment for many minutes in order to achieve proper sanitization.
- When sanitizing stainless steel tanks, it is not recommended that sulfite be used because it has a propensity to discolor these sorts of containers.
It is recommended that you use a mild cleaning that is particularly developed for stainless steel. When dealing with sulfite, be sure to work in an environment that is adequately ventilated. When inhaled, the powerful fragrance can become overwhelming and irritate the nasal passages and throat.
Sulfiting Made Easy
Unless you have a science degree, understanding the chemistry of sulfites might be difficult. If you understand the fundamental ideas provided here, you should be able to handle sulfite additions with confidence and without worrying about whether you’ve added too much or too little. And remember, if you keep within the suggested free SO 2ranges, you won’t have to be concerned about slight variances. unless you’re running a commercial vineyard, of course!
Adding Sulfites To Homemade Wine
I began creating fruit wine in May of this year. I stumbled across something on your site yesterday that piqued my interest and I decided to read it. There is something new that I haven’t read or heard before. That is, after each racking, Campden pills and sorbate should be added. Is it necessary to do this after each racking or is it sufficient to do so after every other racking? … Is it possible that I may lose my wine because I have not added any since I began and because I am on my third and fourth rackings?.
- In no way, shape, or form, has the fact that you have not been adding sulfitesto to your homemade wine deemed you to have harmed it.
- Having said that, I strongly advise you to begin incorporating sulfites into your homemade wine.
- After the wine has been produced, sulfites aid in the preservation of the wine, allowing it to be kept for many years rather than just a few weeks or months in the wine bottle.
- This is the stage at which the color of the wine darkens and the flavor begins to taste slightly bitter.
- When it comes to potassium sorbate, things are a little more complicated.
- It is essential if you plan on back-sweetening your wine at the time of bottling your product.
- This can finally result in corks exploding and wine becoming effervescent.
It is actually more likely to result in a slow or stalled fermentation if it is applied before the fermentation has finished.
It isn’t absolutely required.
Continue to let the wine must exposed for the next 24 hours in order for the sulfite gas to evaporate.
This will readily remove any wild molds, bacteria, and other pathogens that may be present on the fruit as a result of the process.
The dose that maintains the wine fresh and free of oxidation while it is stored in the wine bottle is this one.
In addition, I recommend adding sulfites to wine once the fermentation process is complete.
During the cleaning process, this will prevent any airborne pollutants from developing on your wine.
Please don’t be concerned if you intend to bottle your wine within a few days.
Just the price per gallon.
Unless you want to sweeten your wine, you shouldn’t use potassium sorbate in your recipe.
It’s similar to purchasing insurance for the purpose of producing wine that will not deteriorate or oxidize.
Best wishes for your winemaking endeavors.

How Sulfites Affect a Wine’s Chemistry
There have been many disputes concerning sulfite additives and their effects on wine since the introduction of natural wine, as well as the strong opinions that have occasionally been associated with it—or against it. Chemistry, rather than ideology, may be more useful in resolving those disagreements, and scientific research is increasingly showing that sulfites have a very wide range of effects on wine’s aromas, mouthfeel, structure, and development in both the cellar and the bottle, as well as on its development in the bottle.
While SO2 is useful in this fashion, it is also capable of performing a wide range of other functions, particularly during the early stages of vinification, when it is involved in a large number of reactions and transformations.
Scientists and winemakers are becoming increasingly aware of the many different impacts that sulfur has on the chemistry of wine. In the words of Régis Gougeon, professor of enology at the Universityof Burgundyin Dijon, France, who has been researching the subject for more than a decade, “what research is increasingly showing is that changing the amount of sulfite added to wine—or eliminating it entirely—means changing both the organoleptic characteristics of the wine and the entire chemical profile of the wine.” Don’t miss out on the latest news and insights from the beverages business.
- Become a subscriber to our award-winning Daily Dispatch newsletter, which will be delivered to your inbox once a week.
- The sulfite levels in fermenting or aging wine affect phenolic components such as tannins and anthocyanins, as well as the way they mix at the molecular level, in a number of ways that are yet not completely understood.
- Aromatic components such as esters and thiols, as well as their kind and distribution, are also influenced.
- While winemaking and barrel aging with little or no sulfur addition will significantly diminish the level of these thiols, the result will be an olfactory profile that is more oriented toward mineral, lemony, or tropical notes.
The formation and prevalence of many other compounds will be influenced by sulfur-related reactions, including aldehydes, which are associated with the appearance of oxidative character; amino acids, which are involved in the development of various polyphenols and aromatic compounds; peptides and fusel alcohols; and things like hydrogen sulfide (H2S), which can produce reductiveoff-flavors such as rotten egg, and various polysulfides.
- Similarly, the way sulfur is present in the wine—whether it is bound in those different compounds or is accessible as free SO2—affects the way chemical reactions evolve during and after the vinification process.
- Going back several years, Gougeon and his colleagues discovered that “memories” of sulfur additions persisted in Chardonnays that had undergone three different levels of sulfite additions, even after several years of bottle age.
- While the wines matured in bottle, the variations in chemical composition associated with sulfite additions were noticeable and persistent.
- It is believed that the earlier sulfite additions are made, the more sulfur remains in the wine.” Not only does a larger concentration of SO2 remain in the wine longer, but the SO2 also remains in the wine longer since it has been more intrinsically bonded into the wine.
“In addition, there’s a kind of addictive mechanism going on at work,” Gougeon explains. In many cases, once you start adding SO2, you’ll have to continue to add more. It is necessary to do so because otherwise the sulfur would evaporate, weakening the barrier against oxidation. Wine
What We Talk About When We Talk About Sulfites
How sommeliers and wine sellers cope with the dreaded “S” word—and strive to debunk falsehoods about sulfites in wine—is detailed in this article.
Mapping Sulfur’s Effects
Scientists have been studying the impacts of sulfur on wines for the past decade, using a novel technique called metabolomics to discover more about the compounds. To produce a complete map of a substance’s chemical landscape, metabolomics use a variety of analytical techniques, such as gas chromatography and mass spectrometry, to integrate several modes of study. Unlike chemical analysis, which focuses on specific chemicals, metabolomics aims to reveal every molecule in a wine, whether it is known or unknown, in order to generate a comprehensive picture of that wine.
“We thought there were a few thousand chemicals in wine,” says Gougeon, “but now, thanks to metabolomics, we know there are tens of thousands, many of which have yet to be discovered.” Gougeon is a professor of chemistry at the University of Bordeaux.
According to a study published in Nature in January 2018 led by Fulvio Mattivi, a researcher at theFondazione Edmund Machin Trento, Italy, and a pioneer in the application of metabolomics in wine research, compounds known as flavanols and indoles, which play a role in the mouthfeel and aging characteristics of wine, are significantly affected by the use of SO2 during winemaking.
In the paper’s conclusion, the authors urge that the chemistry of SO2 and its effects on wine be reevaluated, something for which metabolomics is opening up new possibilities.
The Winemaker’s Point of View
What is more relevant on a practical level is how the impacts of different sulfite regimens manifest themselves within a wine cellar. Some winemakers who have made both sulfite-added and no-added-sulfur wines in tandem concur with Gougeon’s opinions regarding the very diverse trajectories achieved by both procedures. Matthieu Carliez is a French actor. Florence Clot captured this image. Vinification with and without sulfite additions is practiced by Matthieu Carliez, the technical director for theVignobles JeanJeangroup’s estates in the Languedoc region of France.
- For the most part, Carliez’s view is consistent with the findings of Gougeon’s research, particularly when it comes to oxidation.
- A fraction of the her Pinot Noirs is crushed, destemmed, and sulfited at the crush pad, while the remainder are whole-bunch fermented and foot trodden, with no sulfur added at any step of vinification or barrel aging.
- “When they’re young, the no-sulfur wines have a tendency to taste older,” adds Naudin.
- As a counterpoint, the wine usually remains more aromatically stable over time, since the oxidative reactions that yield those traits have already taken place.
- “During alcoholic fermentation, the impact is enormous,” she says.
- For me, the cassis notes are very much connected to sulfur additions before fermentation.” She also notices more floral notes in her unsulfured red wines, though she admits that this could result from the whole-bunch fermentation.
- Left: Claire Naudin (photo courtesy of herself) (photo courtesy of herself).
- Gougeon believes that a better understanding of how sulfur affects wine style could lead winemakers toward less dogmatic approaches to sulfite management.
- “What we are currently lacking is a reliable set of indicators that could tell winemakers which wines could be made without sulfur and which ones might need some.

The Truth About Sulfites in Wine — A Matter of Taste
Sulfites are frequently held responsible for the development of wine hangovers. However, they have not been proved to cause headaches or any other health problems in 99 percent of the people who have tried them. Sulfite sensitivity affects around one percent of the population. It is possible that you are among the 1 percent who will get headaches, stomach troubles, rashes, and even heart problems after eating sulfites. Having said that, sulfites may be found in a variety of common foods, and in many cases, in far higher concentrations than the sulfites found in wine.
- A variety of dried fruits, pickled foods, jams and jellies, potato chips, French fries, shrimp, scallops, parmesan cheese, mushrooms, and other foods are available.
If you are able to consume the items listed above, it is likely that you do not have a sulfite sensitivity. What is the point of labeling wine bottles with the words “contains sulfites” if sulfites are completely harmless? To protect the 1 percent of the population who are sensitive to sulfite, sulfite labeling is required. The Food and Drug Administration (FDA) identified sulfite sensitivity in the 1980s and began mandating a “contains sulfites” label on foods in 1988 in order to protect the few people who were affected.
What do high sulfite levels in wine mean?
The likelihood is that you do not have a sensitivity to sulfite because you can consume the items listed above. What is the point of labeling wine bottles with the words “contains sulfites” if sulfites are completely harmless? – For the 1% of the population who are sensitive to sulfur compounds, sulfite labeling is required. Since its discovery in the 1980s, the FDA has required a “contains sulfites” label on products in order to protect the small number of persons who are sensitive to sulfite compounds.
If Sulfites Are Safe, Why Avoid Them?
Sulfites are generally considered to be safe from a health standpoint for the majority of individuals. Sulfites, on the other hand, are extremely important in the winemaking process. Isabelle Legeron is one of 369 persons in the world to earn the title of Master of Wine, which is the highest winemaking accreditation available. A low sulfite content in wine is one of Isabelle’s primary criteria for Natural Wine, and this is one of the most important criterion she has established. Low-sulfite wine is an absolute must-have for her.
- Isabelle isn’t the only one who feels this way.
- While touring their vineyards, we hear the same complaint again and over: excessive sulfites damage the taste of their wine.
- They eliminate germs and yeasts, which makes the process of creating wine much simpler and faster.
- They keep things simple and shockingly predictable.
- Winemakers must achieve the proper balance in their wines, which necessitates a degree of patience, knowledge (and love) that is lacking in many commercial wine enterprises.
- Natural wines offer an authenticity of flavor that most modern wines have lost in the process of modernization.
- They burst forth from the glass with a vivacity that is all too unusual in today’s world of wine production.
With Natural Wine, you can taste its origins, itsterroir, and all of the intricacies that distinguish each bottle of wine from the rest. This is only achievable in low-sulfite wines, which are rare.
Sulfites in Natural Wine
Natural Wine is a work of art for the winemakers with whom we collaborate. Each glass is a manifestation of the complex dance that takes place between the winemaker’s talent and the wisdom of Nature. During the sterilizing process, sulfites eliminate those subtleties, leaving the wine flat and uninteresting. Sulfites may not pose a significant health risk, yet they are extremely important when it comes to product quality. When it comes to sulfites in wine, we at Dry Farm Wines adhere to Isabelle Legeron’s standards.
With this cutoff, we can assure that all of the wines we provide are pure representations of Nature, and that they were crafted with remarkable care by the best winemakers the world has to offer!
For those who have avoided commercial wine, we encourage you to give Dry Farm Wines a try.
They are the cleanest Natural Wines on the globe, and they are ideal for anyone who is concerned about what they put into their body.

The Facts About Sulfites in Wine
Unless otherwise stated, we independently choose these items, and we may receive a commission if you purchase through one of our links. Stocksy image courtesy of Jayme Burrows. A warning label states, “This product contains Sulfites.” In fact, these are the phrases that may be seen on practically every bottle of wine. Even though they are only two short words, they are often misconstrued! Sulfites are a type of chemical compound that may be found in a variety of foods. Honestly, are they all that terrible?
How Much Sulfites Are in Wine?
The quantity of sulfites that can be found in a glass of wine is strictly regulated all around the world. In the United States, any wine with more than 10 parts per million (ppm) sulfur dioxide must be labeled with the phrase “contains sulfites.”
4 Myths About Sulfites in Wine
Here are four fallacies concerning sulfites and wine that I’ve discovered are widely held to be false by the general public.
Myth1: Sulfites in Wine Cause Headaches
Despite extensive medical study, there is still no conclusive evidence linking sulfites to headaches.
There are several other components in wine, such as histamines and tannins, that are more likely to be associated with the headache impact (not to mention the presence of alcohol!).
Myth2: Red Wine Has Extra Sulfites, Thus It Causes Headaches
In the European Union, the maximum quantities of sulfur dioxide that a wine can contain are 210 parts per million (ppm) for white wine, 400 parts per million (ppm) for sweet wines — and 160 parts per million (ppm) for red wine. In the United States, Australia, and other parts of the world, very comparable amounts are seen. Factual statement: Red wines often have lower levels of sulfites than white wines. Why do red wines contain less sulfites than white wines? Almost all red wines undergo malolactic fermentation, which serves as a stabilizing factor due to the presence of tannin in the wine.
Myth3: Wine Should Be Avoided Because It Contains Sulfites
The fact that wine has around ten times less sulfite than most dried fruits, which can contain amounts of up to 1000 parts per million (ppm), is another startling information to learn. As a result, if you consume dried fruit on a daily basis and do not have any negative reactions, you are most likely not sensitive to sulfites. Fact: Dried fruits contain approximately ten times the sulfites found in wine. While the values I’ve provided represent the maximum SO2 levels allowed by law, interactions with several winemakers over the years have led me to conclude that, in fact, sulfite levels are typically substantially below the maximum authorized limits.
Myth4: Sulfites Are Inherently Unnatural
Aside from the possibility of an allergic response, many individuals are opposed to sulfites because they believe they are an unnatural addition to the process of winemaking. While that point of view is correct, it is vital to realize that sulfites are also a natural by-product of the yeast metabolism that occurs throughout the fermentation procedure. Consequently, even if you do not add any extra SO2, your wine will still contain sulfite compounds. Succinctly, a better understanding of how sulfur dioxide breaks down and binds with other components of the winemaking process, improved winery hygiene, and more careful grape-growing practices to ensure healthy grapes (i.e., no rot) have all contributed to a significant reduction in the need for SO2 additions during the winemaking process.
Why Sulfites Are Often Necessary in Wine
There are extremely few wines that are produced without the addition of sulfur dioxide (SO2). This is due to the fact that wine is perishable, susceptible to oxidation, and susceptible to the production of aldehyde off-odors. The presence of SO2, particularly in white wines, is critical for freshness. Wines that do not contain SO2 have a shorter shelf life – around six months – and must be stored in ideal conditions to maintain their quality. Given the fact that a winemaker has very little control over the wine’s storage conditions from the time the wine leaves the winery until it is consumed, it is no surprise that SO2 is widely used to help ensure that the bottle of wine you open will be fresh and clean, and will taste exactly as the winemaker intended when it is first opened.
Another reason why you’ll notice more wines labeled’produced from organically cultivated grapes’ than wines branded ‘organic wine’ in the United States is because organic wine in the United States cannot be manufactured with any added sulfur dioxide.
Avoiding Sulfites? Some Thoughts on Sulfur-Free Wines.
However, we are beginning to see a variety of “natural” wines on the market, which contain little or no SO2 and are thus more environmentally friendly. This is a wonderful development for the tiny percentage of the population who are allergic to sulfites, and the biodynamic wine movement is also intriguing and good for a variety of reasons that go well beyond the elimination of sulfites from the wine. Red wines are particularly easy to avoid sulfites when they include tannin, which works as an antioxidant in its own right (as previously stated).
Natural wines have a distinct local flavor that contributes to their allure; they’re frequently best found in the region where they were produced.
- CatherinePierre Breton is a native of the Loire Valley. They create a single wine without adding any SO2 throughout the winemaking process. 2006 A 100% Cabernet Franc blend, CatherinePierre Breton Bourgueil Nuits d’Ivresse ($26) is produced by CatherinePierre Breton. It is created from grapes that have been farmed naturally and has not been sulfured or filtered. A clear statement on the label warns that the wine “doit être stocké en dessous de 14oC,” indicating that the wine should be stored at a temperature lower than 14 degrees Celsius (57 degrees F). Note: A trace quantity of stabilizer is added before bottling in order to keep the wine stable throughout transportation, but the amount is so little that it is undetectable in testing
- Pierre Frick from Alsace produces a line of wines known as’sans souffre’ (without suffering). The’sans souffre’ Riesling and Pinot Noir wines from 2007 are available at Chambers Street Wines in New York City (for around $22 to $24). Frey Vineyards, Mendocino– One of California’s earliest organic and biodynamic vineyards, and one of the state’s most prestigious. Their product line includes wines that have been produced without the use of sulfur dioxide. Only $8 may be spent on organic Natural Red, NV from Mendocino, which is a combination of Carignane, Zinfandel, and Syrah grapes. Their whiteness is unadulterated by sulfur. It costs $8 for an organic natural white wine, which is a combination of Chenin Blanc and Chardonnay. The Languedoc region’s Domaine des Deux nes is another organic wine maker that uses extremely low sulfites. In my piece last week on the wines of the Languedoc Roussillon, I highlighted one of their wines, which was a red blend. Excellent value for money, great wines, and readily available
So Why Do I Get a Headache When I Drink Red Wine?
Sulfites, on the other hand, are not the likely cause of the well-known phenomena of red wine headaches, as evidenced by all of the scientific evidence to the contrary. Histamines, the amount of alcohol in the drink itself, and tannins are all other possibilities, as I already said. According to the most recent evidence, the latter is true: What is your opinion on the presence of sulfites in wine? Do you suffer the dreaded red wine headaches? Do you know what they are? Mary Gorman-McAdams is a writer and actress.
As a result of this recognition, she was named Dame Chevalier de L’Ordre des Coteaux de Champagne in 2012.
Wine Sulfites Are Fine, But Here’s How to Remove Them Anyway
Having said that, many people report experiencing headaches after consuming red wine, to the point where the term “Red Wine Headache” (RWH) has been coined. While the chemistry behind it is still a mystery, significant candidates include histamine and tyramine, two natural compounds that may cause high blood pressure and headaches when consumed in large quantities. (Fun fact: Red wines have more histamine than white wines, while white wines contain significantly more sulfite.) Another uncomfortable point is that wine includes a lot of alcohol, which has a substantial dehydrating—and hence causing a headache—effect on the body.
- Alternatively, you may still believe that sulfites are causing your headache.
- As it turns out, there is a technique, and it is considerably less high-tech than you might expect.
- A chemical reaction occurs between hydrogen peroxide and sulfur dioxide, converting sulfur dioxide into hydrogen sulfate, which does not create the issues associated with sulfites.
- Sulfites are present in wine in small amounts, and a variety of treatments on the market claim to remove them.
- An alternative version, meant to desulfitize a whole bottle, is also available in a single-use package format.
- Despite the fancy terminology that surrounds these treatments, it doesn’t take long to figure out what their active ingredients are: water and hydrogen peroxide, to be precise.
- I experimented with ancient and young wines, native and imported wines, and reds and whites of various ages.
- However, while these strips employ different shades of pink to estimate sulfites and cannot provide an exact figure, I discovered that untreated wines had sulfite levels between 50 and 100 mg/L, which is precisely what the majority of wine industry professionals state.
- Two sprays of SO 2 GO were advised, which reduced sulfites by approximately one-third, but another couple of sprays brought it closer to parity with Just the Wine.
- Pouring roughly a half-ounce of normal drugstore hydrogen peroxide into a glass of wine was enough to practically eradicate the sulfites entirely, just for fun, and it worked perfectly.
Although the custom products were made from the same ingredients as the bulk peroxide, it was far easier to control their application and they were arguably safer than using bulk peroxide because both claim to use “food grade” hydrogen peroxide in their formulation and are intended for small-scale use.
TL;DR version of this is that sulfites are not likely to cause headaches-at least, they are not likely to cause your headaches-but if you are concerned about sulfites, you can scale them back a bit (but not totally) by using some basic hydrogen peroxide drops.
