How To Tell If Wine Is Bad?

Here are some ways to tell if wine is terrible:

  • First, you should always be cautious of the wine’s color and taste. If the color is sour, the wine is terrible. The taste is not essential, but the smell will be.
  • The consistency of the wine is another clue. If it is cloudy, it’s too old and won’t taste good. Look for signs of overripeness. This will make the wine less appealing. It’s also not advisable to drink a wrong bottle of a specific wine.
  • If the wine has an unpleasant smell, it might be oxidized. This happens when a wine is exposed to air, and the bacteria turns the sugar and alcohol into acetic acid.
  • If the corks push out of the bottle, the wine has been exposed to heat or oxygen. A bulging foil seal means the wine has been exposed to too much heat.
  • Once a wine is open, it can go wrong, and when it becomes unpalatable, it can lose its quality. The most common signs of a sour wine include the smell of acetic acid.
  • The smell of a wine that has gone bad is not pleasant. In this case, you should immediately remove it from the fridge. If you’re not a knowledgeable wine drinker, then it’s likely that the wine has gone wrong.

If you notice any of these signs, you should throw them away. Even if it isn’t harmful, it should be discarded. Instead, it would help if you learned to detect the different smells of lousy wine to avoid a soggy newspaper mouth. This will help you choose the best wine to drink. If you’re unsure, ask your server to check the bottle. It’s always best to drink wine that’s not spoiled.

How Long Does Unopened Wine Last?


A wine that has not been opened has a longer shelf life than wine that has been opened. As a result, as long as the wine is stored correctly, it can last for an extended period. To keep the wine fresh, store it in a cool, dark place and turn the bottle on its side to avoid the cork from drying out.

The following is an estimate of how long some wines will last if stored properly and not opened after the printed expiration date:

  • Bottled white wine: 1–2 years
  • Bottled rosé: 1–2 years
  • Bottled red wine: 2–3 years
  • Non-vintage sparkling wine: 3–4 years
  • Vintage sparkling wine: 5–10 years
  • Fortified wine: decades

How Long Does Open Wine Last?

Because once a bottle of wine is opened, it begins to oxidize, it does not last as long as unopened wine. When you open a bottle, the wine inside comes into contact with air, starting the oxidation process. Wine can deteriorate due to oxidation, which can transform it into vinegar.

Bacteria and other microorganisms Wine spoilage can also be caused by. Bacteria can change the flavor and consistency of open wine if they come into touch with it. If a person does not intend to drink a bottle of wine, they should reduce the amount of oxygen and germs that come into contact with it to extend its shelf life. They can accomplish this by replacing the cork or screw-top on the bottle and storing it in an appropriate location for the wine. For example, people can store white wine in the refrigerator and red wine in an excellent darkroom.

Below is an estimate of how long certain wines may last if a person stores them correctly once they are open:

  • Sparkling wine: 1–2 days
  • White wine:3–5 days
  • Rosé wine:3–5 days
  • Red wine:3–6 days
  • Fortified wine:1–3 weeks

Health Risks Of Consuming Spoiled Wine

Although a person can drink a small amount of rotten wine without harm, they should not consume vast quantities of it. Wine spoilage is usually caused by oxidation, which causes the wine to turn into vinegar. Although it has an awful taste, it is unlikely to damage you.
Food poisoning can occur as a result of deterioration caused by bacteria. This form of spoiling is uncommon, but it does happen.
The following are some of the most common signs and symptoms of food poisoning:

  • Stomach Cramps
  • Nausea
  • Vomiting
  • Diarrhea
  • Fever
  • Dehydration
If a person suspects their wine has gone wrong, they should discard it immediately because it will taste awful and may make them sick.

How To Store Wine Correctly?

People should consider the following points when storing wine:

Choose A Cool And Dark Place

Wine should be kept in an excellent, consistent temperature environment, and temperature fluctuations might impact the wine’s quality. It’s also crucial to keep the wine away from light; therefore, it’s better to keep it in a dark place.

Store Corked Bottles Horizontally

When you store a bottle on its side, the wine is in constant touch with the cork, which keeps it from drying out. If the cork dries out, it may allow oxygen into the bottle, causing the wine to deteriorate.
This sort of deterioration only affects wines in corked bottles. Thus, bottles with a screw-top can be stored upright.

The Right Humidity Is Important

Humidity levels that are too high or too low can also harm a wine. According to anecdotal data, relative humidity of roughly 60% is best for wine preservation.
The cork may dry out if the humidity is too low, allowing oxygen to enter the bottle and harm the wine. If the humidity is too high, mold can form, and any wine labels deteriorate.

Consider A Wine Fridge

If a person does not have access to a handy storage location that is dark, cool, and damp, they may want to consider investing in a wine fridge.
These refrigerators, sometimes known as wine coolers, are not as cold as conventional refrigerators and assist keep wine at the proper temperature and humidity for storage.


If you cannot identify the smell, you can still smell the wine. This can be a sign that the wine has gone wrong. This is an excellent sign that the wine is spoiled. If you can identify these signs, you’ll be able to avoid the mouthfuls of the soggy newspaper. In addition to the smell, you can also look at the color. A bright red wine looks and feels great. If the color is not correct, the label is ruined.
