Do Ice Wines Go Bad?

From the name, fortified wines are more protected from the danger of going bad because of distilled spirit present in them. This is because of their high sugar content, the high alcohol content of about 20%, and some level of acidity, all of which help to sustain their flavor for many years. This is what Ice Wine is.

Generally, every wine can go bad. They all tend to go bad, depending on their type and how they are stored.

The difference is that some wines go bad faster than others. While some wines should be consumed at most, 2 days after they are opened (an example is a Sparkling Wine), other wines can last a few more days (Rose wine, Red Wine) and some a month (Fortified Wine).

Hitting the nail on the head, Ice wines go bad, only that they last longer compared to other wines. Fortified wines are the longest-lasting wines.

Why Do Ice Wines Go Bad?

Generally, wines go bad because of their exposure to oxygen. When wines become exposed to oxygen, bacteria begin to act on them and produce an acetic acid that turns the wine into alcohol, reducing the quality of the wine. In the same way, when Ice Wines get exposed, they also go bad.

However, this is a major condition that can reduce the shelf life of ice wines. Other than this, they can last 20-30 years when they are not opened and about a week if they’re opened.

It is advised that they are kept in the pantry if unopened, but tightly sealed in the refrigerator if it’s been opened already. This is why you shouldn’t joke with good storage measures. You should always keep your wines in cool and dark places.

If you can be sure about the quality of the Ice Wine, then you can be sure it will last for a very long time, as long as you don’t break preservation rules.
