How Long Does Wine Last After Opening (And Why)?

Exact Answer: 3 to 5 days

Wine is a very famous alcoholic drink. It is generally made by fermentation of grapes, although other methods of its creation are also well known. Apart from grapes, yeast also plays a significant role in making wine by converting the sugar of grapes into carbon dioxide and ethanol.

Why Wine Lasts For So Long After Opening?

The safe to consume period for a bottle of wine depends upon a wide range of factors. Among these issues, a prominent issue is whether the seal of the bottle is broken or not. If this seal is broken, the wine will last for a lot less than expected.

However, if proper measures are taken care of, there are chances of delay in its expiry and helps to extend its shelf life by a considerable extent. A few important steps that can be taken to keep the wine ready to consume for longer include keeping it in a fridge or a place that is cool and dark. At the same time, the opening of the bottle should be covered to prevent the addition of any unfavorable substance to the wine.

If the wine is stored in a place with heat and light, it would promote unwanted fermentation of the wine. This is because heat and light would lead to the growth of certain microorganisms which cause fermentation. Thus, when the wine is kept in a place that has low temperature and is dark, it tends to last longer.

Most wines last for just a couple of days after opening. However, some wines like Fortified wine and Bag in Box Wine tend to last for over a month.

For wines to last longer, it is imperative to store them in a proper place and with a cork or a stopper in place. The fridge is an appropriate place to store the wine as it has less temperature and is dark.
