Corked Wine This means that the cork of the bottle has been infected with a bacteria called Trichloroanisole (‘TCA’ for short). A ‘corked’ wine will smell and taste like musty cardboard, wet dog, or a moldy basement. Screwcaps and synthetic corks will not have cork taint.
- The Taste of Corked Wine. While unpleasant to taste, cork taint is not in any way harmful to humans. Corked wines smell and taste of damp, soggy, wet or rotten cardboard. Cork taint dulls the fruit in a wine, renders it lackluster and cuts the finish.

Is it OK to drink corked wine?
Is corked wine safe to drink? Yes. Cork taint isn’t bad for you; it just really dampens the mood.
Can corked wine make you sick?
The extent of what most people know about wine that is said to be corked, however, is that it just isn’t going to taste very good. Corked wine won’t make you sick, but it sure does taste bad.
What happens when a wine is corked?
Corked wines smell and taste of damp, soggy, wet or rotten cardboard. Cork taint dulls the fruit in a wine, renders it lackluster and cuts the finish. The obviousness of the corked smell and taste depends both on the extent of the taint, as well as the wine drinker’s sensitivity to it (aka your cork taste threshold).
What does spoiled wine taste like?
A wine that has gone bad from being left open will have a sharp sour flavor similar to vinegar that will often burn your nasal passages in a similar way to horseradish. It will also commonly have caramelized applesauce-like flavors (aka “Sherried” flavors) from the oxidation.
How do you tell if a bottle is corked?
A ‘corked’ wine will smell and taste like musty cardboard, wet dog, or a moldy basement. It’s very easy to identify! Some wines have just the faintest hint of TCA- which will essentially rob the wine of its aromas and make it taste flat. Only wines closed with a natural cork will have this problem!
How common is corked wine?
There is no scientific number we can reference as to the exact percentage of wine bottles that are corked. Estimates range from 3% to 8%. That is a lot more corked bottles of wine than every wine loving consumer wishes they encountered. Issues with corks is the number one problem and fault with wine today.
How long does unopened wine last?
The best way to enjoy your wine fresh is to drink it shortly after you purchase it. However, you can still enjoy unopened wine about 1–5 years after the expiration date, while leftover wine can be enjoyed 1–5 days after it has been opened, depending on the type of wine.
Can a screw top wine be corked?
Can a screw-cap wine be “corked?” Yes, it can, though it depends on how strictly you define the term. Contrary to almost universal belief, screw-cap wines are indeed susceptible to the sort of mouldy, off aromas typically associated with contaminated corks.
Can you drink opened wine after 2 weeks?
Drinking an already-opened bottle of wine will not make you sick. You can usually leave it for at least a few days before the wine starts to taste different. Pouring yourself a glass from a bottle that’s been open for longer than a week may leave you with an unpleasant taste in your mouth.
Is wine bad if cork is wet?
No, a wine cork should never be wet or soaked. It should be moist at most, providing enough moisture to keep oxygen and air from seeping into the wine and creating an unpleasant flavor and odor.
How should you test whether a wine is cork tainted?
The best way is to start by smelling the wet end of the cork every time you open a bottle. Look for a faint or strong musty aroma. Then smell the wine and look for the same. The more you practice detecting cork taint, the more sensitive you will become to it.
What do you do with corked red wine?
It is perfectly all right to return a bottle of corked wine. Politely request a replacement bottle. If the wine has been bought from a store or mall, pour the wine back into the bottle and return it to the store for a substitute.
Does corked wine taste like vinegar?
The answer is technically yes. But not really. Without getting into too many technical details, the reason that vinegar tastes like vinegar is acetic acid. And acetic acid can form in wine when it gets ‘infected’ with Acetibacter bacteria.
Can spoiled wine make you sick?
If it goes bad, it may alter in taste, smell, and consistency. In rare cases, spoiled wine can make a person sick. Many adults of drinking age consume wine, and evidence suggests that moderate consumption may have health benefits. However, excessive alcohol consumption can harm a person’s health.
Corked Wine Smell Guide: How To Tell If Wine Is Corked
It is estimated that corked wine, or wine that has been tainted by cork, occurs in around five percent of cork-enclosed bottles. Therefore, if you are a frequent wine drinker, you are more than likely to come across a corked bottle or two over your lifetime. How to detect whether your bottle of wine is corked, as well as what to do if it happens, are outlined below. Let’s start with the things that aren’t corked:
- There are no shards of cork floating about in your wine or a cork coated in tiny white crystals that are the problem. These crystals, which are referred to as tartrate, are a naturally occurring by-product of some wines and are completely safe to humans. You also can’t detect if a wine is corked by smelling the cork
- Instead, you have to smell the wine. The fact that the bottle you opened was sealed with a screw cap or synthetic cork means it cannot be corked
- This is a nice tidbit to know.
How Does Wine Become Corked?
The fact that cork is a natural product generated from trees implies that, regardless of cleanliness procedures, certain germs will always be found inside the product’s pores. In the words of VinePair’s taste director, Keith Beavers, “whether you clean it or not, there’s always going to be something in there.” In the case of cork, taint is caused by an enzymatic interaction between chlorophenol, a defect that can occur naturally inside the cork, and fungus. When these two chemicals come into contact, they form a complex known as TCA.
“It will prevent your nose from being able to detect any of the fruits from which the wine is manufactured.” As a result, you’d get a very earthy, odd musty scent,” Beavers explains.
However, while many people assume that TCA has an effect on the physical molecules in a wine, other experts are beginning to suspect that it really interferes with our capacity to smell fruit.
How to Tell if Your Wine Is Corked
You may find it challenging to determine whether your wine has been corked if you have never smelled a corked wine before. “However, once you’ve smelled a corked wine, you’ll never forget it,” Beavers adds of the experience. One method of determining whether or not a wine is corked is to smell and taste it, and then try to identify the notes that you’ve learned to anticipate from the wine’s style and compare them. It’s very safe to assume that something is wrong if a wine normally smells fruity but you aren’t picking up any fruit notes when you smell it for the first time.
“When I used to teach wine lessons and we received a corked wine, I would become really happy,” Beavers recalls, noting that it was frequently his students’ first encounters tasting cork contaminated wine.
What To Do If Your Wine Is Corked
First and foremost, it’s crucial to understand that drinking corked wine is completely harmless. “The only thing that is dangerous in wine is the alcohol,” Beavers claims. In addition, the alcohol in wine would eliminate any unwanted germs that may be potentially damaging to our bodies as a result of the fermentation process. You don’t have to grin and bear it, though, if a bottle of wine that you ordered turns out to be corked. The item can be returned if you so want, according to Beavers. “If your steak wasn’t cooked properly, you’d send it back to the restaurant.
“You’re making a financial investment in something.” Furthermore, restaurants, particularly in larger cities, have a tendency to mark up their wines, so you’re already spending more than you should for that bottle.
In Beavers’ opinion, the only way a screw-capped wine will be bad is if, during the bottling process, any bacteria got on to the glass rim before the cap enclosure was fitted.
More than 30 percent of the world’s wines are now marketed with screw caps, making it easy to avoid drinking wine that has been sealed with a cork in the past.
You should remember that statistics indicate that you will only receive a corked bottle one out of every twenty times; you should use those occurrences as learning opportunities and move on to the next.
What Exactly is a Corked Wine: And What Does Corked Wine Taste Like?
However, I would venture to assume that not as many wine lovers are aware with the phrase “corked wine,” much alone what it tastes like, how it becomes corked in the first place, or even how to recognize when a bottle of wine has been corked. Continue reading to learn more about corked wine, including how it occurs and what it tastes like. What Causes a Bottle of Wine to Become Corked Wine that has been corked does not necessarily refer to a wine that has little pieces of cork floating around in the glass.
- Cork taint is more than just the flavor of a cork in a bottle.
- In the presence of specific chlorides present in bleaches and other winery sanitation / sterilizing chemicals, TCA is generated when natural fungus (of which many are found in cork) come into contact with the substance.
- If left unchecked, TCA has the potential to taint not only a single batch of corks (and wine), but also a whole cellar or winery.
- Since the revelation (which occurred only in the early 1990s) of the root cause of cork taint, the vast majority of wineries have completely discontinued the use of chlorine-based cleaning agents.
- Corked wines have a distinct smell and flavor of damp, soggy, wet, or rotting cardboard, respectively.
- The apparentness of the corked smell and taste is dependent on both the amount of the taint and the level of sensitivity of the wine consumer to the smell and taste (aka your cork taste threshold).
- For example, while I am the wine expert in our home, it is my husband who is able to detect corked wine very immediately after the cork has been removed, no matter how subtle the taint may appear to be.
The increase in popularity of screw-caps and other alternative closures can be attributed in part to the increase in the number of corked wines that have been produced.
However, it is still possible.
It is often assumed that cork is responsible for other wine defects.
(See my February post for additional information on other typical wine blunders.) Is it permissible to bring or send back a corked bottle of wine?
When you return a corked bottle, most retailers will not dispute your decision – however it is ideal if the bottle is not nearly completed!
For those unfamiliar with the art of wine tasting, you may be frightened and fail to identify the taint when the sommelier or waiter initially requests that you try the wine.
If this occurs, my recommendation is to call the waiter back and explain the situation, while also asking him or her to sample the wine.
Cork Taint: Is It Getting Worse or Better?
I open a large number of wine bottles every week, and it is now common for me to go many weeks without discovering a poisoned wine.
Avoid corked wines till next week at the very least!

How to Tell if Wine is Corked
Corked wine may be so unpleasant to drink that some individuals would swear off wine after only one terrible experience with it. But. how can you know whether a bottle of wine has been corked? Because cork taint is difficult to detect, it can be difficult to distinguish between terrible wine and wine that has gone bad. Below, we’ll cover: How often is wine corked? What causes cork taint? What is the source of the problem? What can we do to make a difference? A typical wine consumer may meet around 100 corked bottles in their lifetime.
Corked Wine Clues
Cork taint, also known as TCA in the wine industry and 2, 4, 6, Trichloroanisole to chemists, affects around 2-3 percent of all bottled wines (or about a bottle in every 2 cases). This may seem like a little amount, but if you drink wine on a regular basis, you’ll come across a corked bottle around 100 times in your adult life, which, believe me, can be a big drag. This offer expires on January 31! From now through the end of January, you may save money by purchasing only one book on wine and one digital course.
Amarone della Valpolicella was one of the wines I brought with me on a trip to Los Angeles on one occasion.
Although I was a little off the mark, they had never smelled a corked wine before.
Is corked wine safe to drink?
Yes. Cork taint isn’t harmful to your health; it merely has a negative impact on your emotions.
What does a Corked Wine Smell Like?
The following is the profile of a corked wine containing high levels of TCA:
- Corked wine with high levels of TCA has the following characteristics:
Revisit the Smells of Doom Take a washcloth and dunk it in water before wiping your armpits. Remove the excess water, but do not totally dry it. Place it in a plastic jar with a tight-fitting cover and set it aside overnight. Congratulations! You’ll wake up with a musty towel to smell in the morning. By the way, if a wine has low levels of TCA, it is possible that it will not have the scents described above. Instead, it will just have a lack of fruity and flowery aromas, as well as a lack of flavor.
Examine the following checklist to determine if TCA is the source of the problem:
Cork Taint (TCA) Checklist
- A genuine cork has been used to seal the bottle. (instead of corks, there are other options)
- Is the wine receiving plaudits and receiving evaluations that don’t match what you’re tasting in your glass
- Is your tastebuds acting up once more? (Drink some water, smell your forearm, and repeat the process.) Is it possible that your drinking companion believes it is corked as well?
It takes a little time to become proficient at identifying the corked flavor in wine. If your sommelier tries to take the corked bottle away from you, ask her to leave you a splash so that you may learn from her mistakes as well. She will think you’re strange, but keep in mind that you are the one who has the credit card. TIP: Sniffing out a corked red wine is more difficult than sniffing out a corked white wine.
Handling Corked Wine
If you purchase wine from a restaurant, you have the option of returning it. You should keep your receipts if you purchased the wine online. Many online vendors will gladly provide a refund or ship you a new bottle if you make a mistake. Is it possible to fix a corked wine with Saran Wrap? The Saran Wrap technique, for example, may be familiar to you. Following the aforementioned ‘Amarone Incident,’ I decided to do a bit more investigation. According to chance, Dr. Andrew Waterhouse from the University of California, Davis discovered that the plastic molecules in Saran Wrap adhere to the TCA molecules and ‘pull’ them out of the wine.
Unfortunately, the Saran Wrap wine technique no longer works as effectively as it once did.
source:copyranter Saran Wrap modified the composition of their plastic wrap in 2004.
The first Saran was created in 1933, and it made use of a polymer known as PVDC to do so (polyvinylidene chloride).
PVDC is continued in use today in commercial culinary applications (for example, “frozen turkey wrap”), as well as in commercial vineyard operations to eliminate cork deterioration, among other things.
Where Does TCA Really Come From?
TCA is more bizarre than you may imagine. A reaction occurs when microscopic fungus and bacteria in the air come into touch with chlorine and phenolic chemicals at the exact same moment. As it happens, vineyards are in the business of producing phenolic chemicals, and many wineries formerly utilized chlorine solutions to clean their equipment. While this behavior is now widely recognized as a major no-no, it is extremely difficult to eliminate TCA once it has taken hold. TCA is most commonly introduced into wine by the use of corks.
you guessed it.
Now that you’ve learned how reactive chlorine may be in the presence of wine, you may want to reconsider using it to clean your home.
Ask a Somm: How Do I Know if a Wine Is Corked?
In this column, wine experts from all around the country answer your questions about the wine they drink and how to pair it with different foods. Not every artisan cocktail bar employs a sommelier, but that is precisely the situation at MiniBar, a year-old small, vintage drinking hole in Los Angeles’ Little Tokyo neighborhood. Jeremy Allen works as both general manager and sommelier at the Hollywood location, and he has developed a compact selection of well selected wines that are focused on value and obtained both locally and from Europe.
- Q:How can I tell whether a bottle of wine has been corked?
- Oops, that was not fantastic!
- We are all friends who like spending time with one another.
- Corked wine is an unique condition, more specifically, it is wine that has been contaminated by TCA, a molecule that interacts with wine and causes it to taste and smell like anything from a wet dog to wet cardboard to a beach restroom.
- It is always on the lookout for methods to get into bottles and spoil beautiful wine.
- TCA is difficult to work with since the chemical is employed throughout the winemaking process, all the way up to the point of bottling.
Winemakers battle tooth and nail to prevent it from happening, and the winemaker is victorious 95% of the time.
This is because TCA only responds once the wine has been locked away and left alone with the cork still in the bottle.
It only takes one molecule to make a difference.
Or does it have a scent that reminds you of a rainy forest?
Does it smell like rotting feces, or like the most precious and finest poop on the planet?
Is it the smell of The Village Voiceunderneath the bus stop bench?
Does it have the fragrance of aCORK?
However, if you feel the need to challenge it, then go ahead and do so.
There is a direct correlation between the number of bottles consumed and the likelihood of receiving a faulty bottle.
If a dry cork crumbles, it might be a sign that a vintage wine has been exposed to the elements and is thus less than optimal, but that is a different story.
In addition, in delicate social circumstances, questioning a wine or returning it may make you appear aggressive, finicky, or twerpy to your companions.
It’s a difficult scenario.
It might be for business, it could be for a meeting with the parents, or it may just be to impress a date with your sense of adventure (natural wine and stench), or comfort (fruit-forward guzzle).
However, if it was you who placed the purchase and paid for it, please do not hesitate to return it, or at the very least ask one of our customer care representatives to check.
While I am actually grateful to any customer who participates with us in order to make them happy instantly in the Yelp world, I am grateful to any customer who participates with us in order to make them happy instantly here, inside the bar, before they leave, instead of them not saying anything and blaming us later for the bad wine.

Corked, Cooked, Bretty, Bad: How to Spot 7 Common Wine Flaws
The majority of wine specialists agree that at least one out of every twenty bottles of wine—and potentially as many as one out of every ten—is corked. That is to say, it is defective. Something has gone wrong. It is deserving of a return. Have you consumed a total of ten bottles of wine in the past year? How many have you returned thus far? Or, to put it another way, how many emails have you not returned because you were unaware of the situation? Or it might be that you didn’t want to be awkward or that you didn’t want to appear foolish.
Knowing what to watch out for and how to request a different bottle can make you a lot better drinker in the long run.
You shouldn’t glance at the cork, smell the cork, or search for particles of cork in your glass since none of these will tell you if a wine is corked. Instead, look for signs of cork in the wine. The only way to tell if your wine has been tainted by cork is to smell and taste it. A chemical known as TCA (or 2, 4, 6-trichloranisole for all you chem-nerds) seeps into corks and causes a musty stench to permeate the contents of the bottle. Stick your nose in your glass and take a whiff around for notes of moldy cardboard, musty cellar, or mangy sponge, all of which are frequent markers of the presence of TCA.
“Is it possible to put a shelf in a store window with the sun shining on it? Unfortunately, the bottle of wine is a dud.” “Cooked” refers to a wine that has been exposed to high temperatures for an extended length of time. Even at temperatures slightly over 75 degrees, warm temperatures tend to dull or flatten a wine’s flavor; in severe cases, the wine might take on a stewed, prune-like, or raisin-like flavor. It is at this point that knowing where your wine is sourced is advantageous. Wine storage is extremely important, yet it is much too often disregarded.
Unfortunately, that bottle of wine is a dud.
Cooked wine is also characterized by a sour taste and a bitter aftertaste.
Consider the flavor of a fresh, green Granny Smith apple. Allow it to sit out on the counter for a day after it has been sliced up. This causes the color to turn dark, and the tastes to taste brown as well: dried out, worn-out, and cider-like. Oxidized wines behave in a similar way, and they typically have a nutty flavor to them as well.
Older wines that have been bottled with cork closures can naturally develop some nice, delicate oxidative tastes as a result of the cork allowing a little amount of oxygen to pass through over time. Young wines, on the other hand, should be crisp and fresh.
Look for Band-Aids and barnyards with your nose. In either case, the wine has been infected by a yeast called brettanomyces (also known as brett), which, like any yeast, may be found all over the world. Brett, in particular, like spending time in barrels in vineyards, and once it has taken up residence in your winery, it is famously tough to expel. In fact, several wines have become well-known for their peculiar bretty flavour as a result of this. Some individuals (including this author) appreciate brett in tiny amounts since it may also express meaty and spicy flavors such as bacon, leather, or cloves, among other things.
There is a strong chance that other bottles of the same wine will be damaged in the same way.
VA is an abbreviation for Volatile Acidity, which is naturally found in all wines in trace amounts and which normally does not create difficulties. However, when harmful bacteria such as acetobacter (which transforms wine into vinegar) are present in the winery, a type of wine infection can arise as a result of the interaction of the bacteria, alcohol, and air. In certain instances, VA goes beyond, and the wine’s fresh, fruity aromas are completely eliminated, with just a sour, vinegary taste remaining in their stead.
That is not a positive development.
VA is an abbreviation for Volatile Acidity, which is naturally found in all wines in trace amounts and which normally does not cause difficulties in the drinking of the wine. A wine infection, however, can arise when harmful bacteria such as acetobacter (which transforms wine into vinegar) are present in the winery and the bacteria, alcohol, and air combine to form a wine infection. This is when VA takes a dive into the deep end, destroying the wine’s fresh and fruity notes and replacing them with an overpowering sour and vinegary taste.
Unfortunately, this is not a positive development.
Sulfur is not a fault in and of itself, to state the obvious. Sulfur is not a harmful element in and of itself! In the winemaking process, it is critical to utilize reasonable amounts of sulfur: sulfur helps to prevent additional defects (such as those mentioned above) by acting as a natural preservative and keeping microorganisms at away. Specifying that a wine be created without sulfur is like to requesting that your supper be prepared without the cook washing her hands first. Risky. However, like with everything, having too much of a good thing may be detrimental.
Two more sulfur-related defects have to do with difficult chemical processes that might result in a wine that smells like rotten eggs or garlic and onions, among other unpleasant aromas and flavors.
So you think you’ve spotted a flaw. Now what?
Inquire about a second opinion! Shutterstock Any of the situations listed above justifies requesting a fresh bottle. Please keep in mind that it is usually courteous to do so before you have finished the most of it! In all circumstances, begin your conversation with a straightforward and honest declaration about your likes and preferences at the time of purchase. Make no apprehensions about asking inquiries or seeking guidance. This unique conversation with the salesperson, server, or sommelier will assist to guarantee that you start off on the proper route in the first place.
- Don’t be afraid to take a few sips, swirl them about in your mouth, then swish them around some more.
- The optimal approach is one that is calm, ambiguous, and casual: “Hmm.
- What do you think about it?
- A bottle that has been damaged will be replaced as soon as possible.
- The scenario becomes more complicated if the wine is technically sound but just does not appeal to your personal preferences.
- However, if the wine is extremely pricey, she may find it more difficult to rationalize the purchase.
- The main line is that there’s no danger in reaching out to find out.
- You’ll most likely have a greater understanding of why the wine tastes or smells the way it does, and you’ll be better able to appreciate it for what it truly is.
And, hey, you’ll be correct almost 1 out of every 20 times! The fresh bottle, as well as your following better night’s sleep, will make whatever worry you had about asking completely worthwhile.
How To Tell If a Wine Is Corked
We all enjoy a good glass of wine, don’t we? We enjoy how it helps us relax after a hectic day, how it enhances a good mood, and how it can be used for anything from day drinking to evening winding down, celebrations, tiny moments, and everything in between. But do you know what may completely spoil a bottle of wine? There are many different types of defects and imperfections, one of which we’ll discuss today: corked wine. It’s something you’ve undoubtedly heard about, but you might not be aware of whether or not you’ve really come across it.
Then what exactly is corked wine, and how does it differ from regular wine?
What Is Cork Taint?
A corked wine is one that has been tainted by cork taint, which has a unique smell and flavor and may be distinguished from other wines. Given that cork is a natural substance, the fact that it includes small microbes that prefer to eat implies that it has microorganisms whether the cork is still a part of the tree or after it has been transformed into a wine cork. It has been reported that when these fungus come into touch with cork, they produce the chemical TCA, which destroys the wine the moment it comes into contact with the cork.
What Does It Smell Like?
Never entered a gloomy, moldy cellar or smelt a wet newspaper or a rotting dog till now. The fragrance of corked wine can be described as follows: Because it’s so unpleasant to drink, cork taint is a major wine flaw, and it’s why it’s such a common problem. However, there are several varieties of corked wine. The scent of wet cardboard in a damp, moldy cellar will not be present in every bottle. If there is just a trace amount of TCA, the wine may simply be lacking in scent. Those taste profiles are quite interesting.
What Does It Taste Like?
Knowing how corked wine smells is vital, but it’s even more crucial to know how corked wine tastes! Whether you order a glass at a restaurant or a buddy pours you a glass, it’s possible that you won’t always sniff your drink before you drink it. When you drink a corked wine, the characteristically buoyant wine flavor will be replaced with something flat and lifeless. The fruity aspects of the wine will have vanished, and the wine may even have an astringent flavor. More often than not, you’ll discover that the wine just does not taste as good as it was described.
But don’t be concerned.
In any case, we hope you’ve gained some insight into how to detect if a bottle of wine has been corked.

How to Tell if Wine Is Corked
Documentation Download Documentation Download Documentation One of life’s little joys is savoring a fine bottle of wine with friends. On the other hand, it is estimated that around 5% of the world’s wines are corked, which results in a less than pleasurable experience while drinking wine. In order to detect whether or not a bottle of wine has been corked, it is recommended that you smell the bottle before drinking it. Even though it smells OK, you should still taste it to ensure that it has the strong, fresh aromas you were expecting when you purchased it.
- 1 Take a whiff of the wine. If a bottle of wine has been corked, it will have an odor that you would not expect to find in a decent bottle of wine. It may have a musty scent, or it may smell like damp towels, a wet dog, wet cardboard, or wet newspaper.
- Keep in mind that your initial scent is more dependable than your subsequent sniffs. Don’t believe everything you hear
- Wine becomes corked when it is subjected to TCA, also known as “2,4,6-Trichloroanisole,” a naturally occurring molecule that may be found in the cork of the wine bottle.
- 2 Take a sip of the wine. If the wine has only been exposed to a little quantity of TCA, it may be difficult to determine whether or not it has been corked only by smelling it. When the wine is tasted, it will have a bland flavor and will not have any fruit qualities. Some individuals sometimes characterize corked wine as tasting astringent
- This is a common description.
- A wine that has only a minor cork snag may be devoid of scent and taste, and may even be unpalatable. If you did try it and it turned out to be corked, the flavor was almost certainly unpleasant. It may even have had a flavor that was evocative of paint thinner. Afterwards, rinse your mouth out with water and get a new bottle of water.
- 3 Always taste the wine before serving it to others. This allows the host to determine whether or not the wine is suitable for consumption and stops the host from pouring the wine into several glasses only to learn that the wine is not suitable for consumption. Return your corked wine to the store where you purchased it to receive a replacement or a refund, whichever you want.
- If you are in a restaurant and you purchase a bottle of wine, be certain that the waiter enables you to sample the wine before serving any other visitors at the table
- Otherwise, the wine may be spoiled.
- 4 Avoid conflating a corked bottle of wine with other issues. If anything about the wine doesn’t feel quite right to you, don’t immediately assume that it’s been corked. It’s possible that there are additional factors contributing to the poor taste of your wine
- Oxidized wine is wine that has been exposed to oxygen, resulting in a wine that tastes flat and lifeless, with a slight vinegary flavor. If your wine tastes like this (consider the difference between the flavor of a flat soda and the taste of a fresh soda, as the concept is similar), it is likely that it has simply oxidized. The color of the wine (assuming it is white) will have altered as well, becoming dull yellow or brownish in appearance. Maderized wine is defined as wine that has been warmed, either as a result of storage or during shipping. This wine will have a flavor that is evocative of almonds or candied fruits, and the cork may be pushed out of the bottle a little. This occurs as a result of the expansion that occurs when the wine is exposed to excessive heat
- It is also conceivable that the wine has refermented. In spite of the fact that wine is a result of fermentation, surplus yeast can interact with the wine after it has been bottle and cause it to have a bubbly flavor.
- 1 Understand the process by which a bottle of wine becomes corked. The term “corked wine” refers to wine that has come into touch with a cork that has been tainted by the term “cork taint.” This occurs when a wine cork comes into touch with a molecule known as TCA (2,4,6-Trichloroanisole), which is widely found in wine.
- In wineries, TCA is formed when natural fungi present in corks come into touch with particular chemicals contained in sanitation and sterilizing solutions used in the process of making wine.
- 2Understand what it does not mean to be corked. Many people are under the impression that corked wine is just wine that has little pieces of cork floating about in it. This is incorrect. This isn’t the case at all. Despite the fact that it is irritating, the wine is not damaged
- 3 Keep in mind that it is possible that the contamination was not caused by the cork on the bottle. A screw-top bottle of wine may occasionally be encountered, but it will still have the appearance and flavor of a corked bottle of wine. It is possible that the wine became tainted in the barrel before it was bottled in this instance.
- As a result, you should return the wine to its original location. If a vineyard has sold an entire batch of corked wine, you should take a second look at the quality of that particular wine.

- TCA is difficult to remove from a wine cellar, and once it has been introduced, it has the potential to taint all of the wine in the cellar. There is no evidence that TCA is hazardous to people. Even at two parts per trillion (0.000000000002 kilos in a litre of wine), TCA may be seen by the human eye. It is impossible to identify if a wine has been corked just by smelling the cork. It is necessary to return the corked bottle of wine to the store where you purchased it. If you receive a corked bottle of wine, they should provide you a replacement or a refund. If they don’t, it’s probable that this isn’t a place where you should spend your money in the first place. Simply place the cork back into the bottle and return it to the store with the wine still inside. They may choose to return the wine to the distributor in order to inform them of the corked wine
When TCA is introduced into a cellar, it can taint all of the wine stored inside; it is difficult to remove from a cellar after it has been introduced. In humans, TCA is not toxic. Even at two parts per trillion (0.000000000002 kilos in a litre of wine), TCA may be detected by the human senses. When you smell the cork, you can’t determine if the wine is tainted. It is necessary to return the corked bottle of wine to the retailer from whence it was purchased. If you receive a corked bottle of wine, they should provide you a replacement or refund.
Take the bottle back to the store with the cork still in it and you’ll have a perfectly good bottle of wine!
- In the event that you stumble find a bottle of wine in your collection that has been corked, toss it out. This wine should not be able to infect any of your other wines.
About This Article
Summary of the ArticleXThe best way to identify whether your wine is corked is to sniff it first to check if it smells musty, like a wet dog or a piece of cardboard. When it comes to tasting your wine, go with your initial impression because it is the most dependable. Whether you can’t tell by the fragrance alone, try a sip of the wine and see if it tastes dull or astringent, with no discernible fruit flavor. If so, discard the bottle. Additionally, warming in storage or during shipping might cause your wine to taste wrong, giving it a flavor similar to nuts or candied fruits.

How TCA Enters Wine
The problem begins with the cork that is used to close wine bottles. In the bark of cork trees, there is a naturally occurring mold that can occasionally mix with leftovers of the chlorine used to bleach and clean the corks for commercial use to generate a chemical known as trichloroanisole, which is harmful to humans and the environment (TCA). Indirectly, TCA is directly responsible for the development of the mold that taints the wine and alters its flavor.
As we mentioned, this mold is invisible to our eyes, and it should not be confused with another mold that we can occasionally detect behind the capsule on top of the cork, which is generated by leaking and is completely safe.
What to Do if You Detect TCA
The fact that as many as seven percent of all wines may be corked is crucial for the wine business since it indicates a big problem. It implies that one out of every 15 to 20 bottles of wine that you purchase may be infected, which is bad news for you. If you do happen to come across a corked bottle of wine, it is likely that that specific bottle has been infected and that you should exchange it for another. Remember, this is not a result of a flaw in the vineyard or the wine itself, but rather the result of a lucky break.
Request a replacement bottle in a courteous manner.
The wine industry is becoming increasingly conscious of contaminated wine and has come to terms with a failure rate of around five percent of all wines produced.
Fixing Corked Wine
In the past several years, a French scientist has developed a method to ‘purify’ corked or contaminated wine. Pour the wine into a decanter and then place a plastic that looks like a cluster of grapes into the wine, according to the recipe instructions. The copolymer absorbs the contaminated cork molecules from the wine and returns the scent and flavor of the finished product to its original state.
Corked wine has absolutely nothing to do with the broken or crushed corks that you may discover in wine bottles from time to time. This is a byproduct of a wine bottle that has been poorly opened, and it has no effect on the flavor of the wine. You can discard any broken bits of cork from the bottle and continue to drink the wine as you normally would.
Detecting a Problem With the Wine
It is difficult to tell when a bottle of wine has been corked. It is common for low-level taint to show as a bland taste with little or no change in the scent when the taint is present. Because of the heavy contamination, the wine may have a terrible musty smell that will overpower the other natural fruity smells present in the wine when opened. When you are drinking a wine from a variety that you have already tried or with which you are familiar, it is typically easy to recognize a contaminated wine.
If you notice any weird flavors in the wine, please do not hesitate to return it to the store.

Does Your Wine Taste of Cork
It’s not always easy to tell if your wine has been tainted by cork. If you are a genuine wine specialist, you won’t require any assistance from others. If you are not, however, you should consider the following suggestions before declaring your wine unfit for consumption. The first rule to remember is that “if your cork does not smell like wine, your wine is not corked.” So, if you’re the one who’s going to open the bottle, take a whiff of the bottom end of the cork. A little experience should help you recognize when a bottle of wine is no longer good.
You may take on the role of a sommelier in this situation and smell the wine itself.
Taking a taste of wine is recommended when you have a cold and cannot rely on your sense of smell to identify any unpleasant smells in the wine.
What is the cause of a corked bottle of wine?
Other elements, such as the wooden barrels in which the wine is stored and other storage conditions, might also be responsible for tainting the wine. The detection process in this case, on the other hand, is sophisticated and should be left to actual sommeliers.
Everything You Ever Wanted to Know About Cork Taint
You’ve probably had the experience of sitting down and pouring yourself a glass of wine only to have it smell like a damp newspaper or a moldy cellar. Or have you ever swirled a glass of wine and observed that it smelled muted, or maybe like nothing at all, afterward? If this is the case, it is likely that your wine was polluted by cork, sometimes known as “corked.” It is caused by chemicals that smell like mustyaroma and can contaminate wine. The most prevalent culprit is 2,4,6-trichloroanisole (also known as 2,4,6-trichloroanisole) (TCA).
The cause of cork taint
TCA is generated in tree bark when fungi, mold, or certain bacteria come into contact with a class of fungicides and insecticides known as halophenols, which are a group of fungicides and insecticides that are used in conjunction with each other. Between 1950 and 1980, they were frequently utilized and are still present in the soil. Fungal defense mechanisms chemically modify these chemicals, rendering them harmless to the organism while simultaneously producing TCA in the process. Many winemakers use tree bark to construct corks for their wine closures, but they aren’t always clear if any of the bark was contaminated with fungicides or pesticides before it was used.
- Getty Although there are various methods of tainting wines with TCA, the most prevalent is barrel contamination, followed by equipment contamination and winery contamination.
- TCA can also develop as a result of the reaction of sodium hypochlorite (bleach) with lignin, which is a naturally occurring wood component.
- Following that, mold, yeast, and bacteria transform this molecule into TCA.
- However, it was not until 1981 that the Swiss scientist Hans Tanner and his study team discovered that TCA was the primary source of cork taint in wine, and that this discovery was confirmed by further research.

The effects of cork taint
Fungi, mold, and some bacteria interact with a class of fungicides and insecticides known as the halophenols, which result in the formation of TCA in the bark of trees. In widespread usage between 1950 and 1980, these chemicals were found to be present in soil. Fungal defense mechanisms chemically modify these chemicals, rendering them harmless to the organism while simultaneously producing TCA in the process of doing so. Many winemakers use tree bark to construct corks for their wine closures, but they aren’t always clear if any of the bark was tainted with fungicides or pesticides before it was harvested.
- Getty Although there are additional methods of tainting wines with TCA, the most prevalent is barrel contamination, followed by equipment contamination and then contamination within the winery itself.
- However, this is quite unlikely.
- 2,4,6-trichlorophenol is the result of this reaction (TCP).
- It was not until the early twentieth century that descriptions of cork taint were published.

- Policy Regarding Personal Data Collection and Usage Incredibly, humans can detect TCA concentrations between two and five parts per trillion, with some able to detect levels as low as one part per trillion (see figure).
The pervasiveness of TCA in wine
During blind tastings for Wine Enthusiast, this author discovered that between 3.5 and 6% of the wines tasted by him looked to be tainted by TCA or another musty scent component (the term “appeared” is used because the presence of TCA was not proven by testing). Due to the fact that around 30 billion bottles of wine are produced each year and are sealed with corks, this corresponds to an estimated one billion bottles being damaged by TCA each year. According to the Cork Quality Council, 3 percent of the corks it evaluates are tainted with TCA (triclosan).
There is a common misperception that less costly wines are more prone to be affected by cork than more expensive wines.
Corked bottles of wine, on the other hand, can be purchased for as little as $9 or as much as $120 or more. During the previous year, the average price of a TCA-tainted bottle of wine sampled from Washington was $43.
How to detect cork taint
Winemakers and consumers will have to deal with cork taint until all natural corks can be consistently and individually tested for TCA and other musty chemicals, which is not likely to happen anytime soon. As a customer, the most important thing you can do is learn how to properly identify it when you see it. The most effective method is to begin by sniffing the wet end of the cork every time you open a bottle of liquor. Look for the presence of a mild or strong musty odor. Then take a whiff of the wine and search for the same thing.
- Soon, you will be able to detect more subtle contaminations as well.
- It’s important to remember, though, that they will have an extremely powerful presentation.
- Individual sensitivity to cork taint varies greatly, with some persons able to detect TCA concentrations as low as one part per trillion while others are unable to detect it at 200 times that level, according to the study.
- Even if you are not aware of the existence of the taint, it can nevertheless have an impact on your pleasure of a bottle of wine.
- One day, you may be able to detect cork taint at a concentration of two parts per trillion.
- It is possible to smell a glass and obtain a whiff of it, but when you try to acquire another whiff of it, you are unsuccessful.
- TCA can be found in lower concentrations in some types and kinds, such as many white wines and Pinot Noir, than in others.
- Many others, on the other hand, use the term “corked” to refer to everything that is wrong with a bottle of wine, including wines that they just do not like for or dislike.
- The word should only be applied to bottles that have a musty appearance in their packaging.
- In such cases, the wine does not appear to be contaminated by the cork in any evident way, but rather appears muted and uninspiring.
How to prevent cork taint
Winemakers employ a range of strategies in an attempt to reduce the amount of cork taint in their wines. In order to do this, it is possible to soak a selection of corks from each bale in a neutral alcohol solution and then sniff each cork to detect the presence of TCA. If they discover a tainted cork in a sampling, they will reject the entire bale as a result of the contamination. In addition, some cork producers have begun testing individual corks for the presence of TCA in the recent past.
There is really nothing that customers can do to help in this situation.
Once a wine has been tainted by TCA, it will remain contaminated indefinitely. TCA contamination has absolutely nothing to do with storage conditions such as temperature, humidity, or keeping a wine for an excessive amount of time.
What if I buy cork-tainted wine?
If you purchase a bottle of wine and discover that it has been contaminated with TCA, there is now no remedy. Using some techniques, like as Saran Wrap or a teaspoon of heavy cream, can occasionally reduce the influence of TCA, but they also have a substantial impact on many other aspects of the wine’s flavor and aroma. In lieu of that, you can consider returning it to the shop or vineyard from whence you purchased it. It is common for them to replace the wine at no charge as long as you have your receipt in your possession.
Though returning a bottle of wine you believe to be tainted may be uncomfortable, a competent staff will cheerfully accommodate a courteous request for a replacement bottle.
Unfortunately, for wine collectors and travelers who purchase wine on their travels, certain bottles are irreplaceable and cannot be replaced.
TCA taint was reported to be far greater in the late 2000s than it is currently, possibly affecting as much as 9.5 percent of wines at the time.
Beyond the glass
TCA may appear to be an issue that only affects wine, yet bagged, store-bought baby carrots sometimes have significant amounts of TCA contamination. This is due to the fact that the carrots have been soaked in a weak bleach solution, which might contribute to the creation of trichloroanisole throughout the processing process. There have been anecdotal claims that eating baby carrots has desensitized some persons to the smell of TCA and/or made them dislike the taste of it. TCA can also have an impact on other fruit, such as apples, that is kept or transported in wood crates or cardboard cartons.
