As a general rule, a wine bottle opened for more than a week goes bad. But to ensure that the wine is not suitable for drinking, you need to see its color and appearance.

  • If the wine is cloudy and leaves a film in the bottle, then it is a sign that microbial activity has begun to take place inside the bottle. This microbial activity is responsible for the vinegar-like taste.
  • If the wine’s color changes to a darker shade of brown, then you need to understand that oxidative stress has occurred. Wine goes dark just as a cut apple does when exposed to oxygen. But you cannot judge a wine bottle just by its color as there are some bottles of wine that are in shades of brown.
  • If the wine inside the bottle has tiny bubbles, then it is a sign that it may have gone bad. The bubbles are generated from another unplanned fermentation process occurring in the bottle. You may think that this may turn into a bottle of sparkling wine, but it is not true. The second fermentation process makes the wine sour and spritz.


You Can Tell If Wine Is Bad From The Smell:

You can also tell if the wine has gone bad from its smell. Wines that smell funny, pungent, sour, or sharp may have gone bad.

Sometimes, you may open a bottle of wine to find it smelling weird. This is because of a wine fault which is found in a few bottles at the time of packaging.

A wine that has been left open for too long also may start smelling weird.

Sometimes, the smell may be medicinal or like a nail polish remover or paint thinner.

Such aromas come because the bottle may have been exposed to heat and oxygen for long and subsequent chemical reactions.

These chemical reactions cause bacteria to develop and produce acetic acid and acetaldehyde.

The biggest culprit for spoiled wine is commonly known as ‘cork taint’.

There are different levels of cork taint. But even a mild one can overpower the flavor and smell of the fruit juice.

You certainly cannot have wine spoiled because of cork taint.

Wine does not spoil as it gets older. The alcohol present in the wine acts as a preservative.

Many wine bottles available on the market are older than 50 years or more. The best Vintage Port wines are made for aging.

They are stored in optimal conditions that only makes them more delicious as they age.

In some cases, a wine just gets old but does not age well.

That means that the drink may have lost its fruit flavors and begun to taste more on the nuttier side.

Even the color may have turned into a darker shade of brown. Such a drink may be compared to vinegar.

Generally, wine lasts for one to five days after being opened. You need to minimize the amount of oxygen the wine is being exposed to.

The more the amount of oxygen, the more is the oxidation.

It goes bad only because of the oxidation process.

Good wine lasts for decades in a wine cellar and when not opened at all.

An opened bottle of wine lasts the best in a refrigerator.
