How Many Days Can You Leave a Bottle of Wine Open?

Leaving a bottle of wine open can be a tricky business. On one hand, you don’t want to waste any of the delicious beverage, but on the other hand, you don’t want it to go bad either. So how long can you leave a bottle of wine open before it starts to spoil?

The Short Answer

Generally speaking, an opened bottle of wine will last for about 3-5 days when stored properly in the refrigerator. After that point, the flavor and quality of the wine will start to degrade.

Factors That Affect How Long Wine Lasts

There are several factors that can affect how long an opened bottle of wine will last. The type of wine is one factor; red wines tend to last longer than white wines due to their higher tannin content. The storage conditions are also important; if the bottle is stored at room temperature, it will not last as long as if it were stored in the refrigerator.

Finally, the amount of air that gets into the bottle can also affect its longevity. If you use a vacuum pump or stopper to seal the bottle after opening, it will help keep oxygen out and preserve the flavor and quality of the wine for longer.
