What Does Oxidized Wine Taste Like?

Wine lovers know the significance of storing wine properly.

And most wine enthusiasts will confirm that wine bottles do not have a never-ending lifespan.

Several factors can affect your wine’s quality, especially when exposed to air.

Oxidation is one of them.

It is a chemical reaction that occurs between wine and oxygen.

Oxidized wine can ruin your wine-drinking experience.

But before throwing out an oxidized bottle, you might want to know what oxidized wine tastes like.

Oxidized wine’s taste differs depending on the level of oxidation. In general, it tastes like vinegar, nuts, sherry, or caramel. The fragrance is sour and off-putting.

What is Oxidized Wine?

When people talk about oxidized wine, they are referring to wine that has undergone too much contact with oxygen.

Wines are generally stored in airtight containers like bottles, anything that can let in oxygen compromises its quality.

This exposure can cause the wine to spoil, and the flavors, fragrances, and texture of the wine will alter too much that they become undesirable.

Wine oxidizes naturally through the tiny gaps in corks, or leakage through the cork.

In time, your wine will become undrinkable if it comes into contact with too much oxygen.

The moment oxygen comes into contact with wine, the reaction is almost immediate.

In a short time, oxidation can modify the wine’s taste, texture, and color.

So, if you have a bottle of wine that has been sitting for a while, it’s worth checking it for any signs of oxidation before drinking it.

What Causes Wine to Oxidize?

When wine comes into contact with oxygen, the reaction results in the loss of certain chemical components within the wine.

This alteration can result in a sour or bitter wine taste that leaves you with an unpleasant aftertaste.

Here are the reasons why wine oxidizes:

  • Cork leaks – Most wine bottles have cork stoppers. The corks can either be synthetic or natural.

Corks can shrink or dry out when stored in high heat or humidity, leading to leaks that allow air into the bottle and cause oxidation of the wine.

  • Wine Storage – Wine storage also affects the lifespan of your wine.

Improper temperature settings during storage can speed up the oxidation process, and so can leaving the bottle in an area with direct sunlight.

  • Decanting – Decanting helps aerate wine, but it can also oxidize your wine if left for too long.

Decanting can cause oxidation because of the wine’s exposure to oxygen.

What Does Oxidized Wine Taste Like?

Wine drinkers worldwide describe oxidized wine as having a foul or off-putting scent.

It has lost its freshness and fruitiness and now tastes tart, sour, or vinegary, with a flat and dull finish.

The wine’s color may have changed due to the oxidation of pigments present in the wine that come from grape skins.

Here are some of the common descriptions of the taste of oxidized wine:

  • Vinegar – Oxidized wines have vinegar-like notes that could hit your nose from a mile away.

The sour taste of vinegar is a significant indication that your wine has undergone oxidation.

  • Nuts – Wine drinkers may also describe oxidized wines as having a nutty flavor.

This is because as the wine loses its original vibe, it develops new tastes like nuts, almonds, walnuts, or hazelnuts.

  • Caramel – An oxidized wine can develop a roasted or burnt sensation like caramel.

As the wine breaks down, caramel-like notes may develop as well.

  • Sherry – Wines that are exposed to oxygen can become more like sherry due to the aroma of Acetaldehyde.

The tart flavor and nutty essence in oxidized wines can turn out to be sherry-like and alter the taste dramatically.

  • Flat – Oxidized wines have a flat taste.

The bubbly sensation that comes with a good glass of wine is no longer there.

If left for too long after exposure to oxygen, the wine may become undrinkable.

How to Avoid Oxidized Wine?

Many factors can cause wine to spoil, and it is not always easy to monitor the wine strictly.

But, if you want the best wine-drinking experience, you must take careful care of your wine collection.

Here are a few simple steps to help you avoid oxidized wine:

  • Store wine properly – Store wine in a cool, dry, and dark place.

By doing this, you will ensure that the wine stays fresh for longer.

  • Store the wine at the appropriate temperature – Keep your wine in the right temperature.

Avoid storing your wine in areas near the window, heating or cooling systems, or places with extreme temperatures.

  • Keep the bottle upright – Make sure to keep your bottle upright to prevent the cork from drying out.

Dry corks lead to leaks, causing air to find its way to the wine leading to oxidation.

  • Do not decant for long periods – Decant just the right amount and leave the bottle with the cork for later use.

Decanted wine left for too long can undergo rapid oxidation due to the exposure to air.


Oxidized wine is a term that strikes fear in the hearts of wine enthusiasts.

It is one of the many ways wine can spoil, and it is challenging to detect before you pour a glass and take a sip.
