how long can wine be kept after opening

April 18, 2023
Wine is rich in nutrients such as vitamins, minerals, polyphenols and tannins, and can be consumed in moderation to strengthen the body, tonic, sedative and diuretic. If a bottle of wine is opened, how long can it be kept without deterioration?

How long can wine be kept after opening

The shelf life of wine after opening is very short. Even if the wine is corked immediately after pouring and refrigerated, the shelf life of wine will not exceed one week. And the longer it sits within that week, the worse the taste and nutrition will be.

Why wine has a short shelf life after opening

The nutrients in wine are very rich, but some of the components in wine, such as tannins, are easily oxidized and will undergo a series of chemical reactions when they come into contact with oxygen in the air. 15 minutes after opening a bottle of red wine, the bitterness of the wine becomes lighter and the flavor is better, but the taste becomes sour and the fruit flavor fades when left for more than an hour, and will deteriorate completely if left uncorked for more than a day.

How to keep dry red wine after opening the bottle

Wine that has been in contact with oxygen for too long after opening will lose its nutritional value and become sour in taste. After the wine is opened, the wine should be corked back with the original cork or purchased bottle cork, sealed and stored upside down or flat in a cool place around 12~15 degrees Celsius, away from light and dry, for only 2 days.

How to store sweet red wine after opening

Opened sweet red wine should also be sealed with the original cork or purchased cork substitute and placed in a refrigerator at 0~4℃, upright, with a shelf life of 1 week.

How to extend the shelf life of open bottles of wine

To extend the shelf life of an open bottle of wine, it is best to purchase a vacuum pump to extract the gas that enters the bottle, which will slightly extend the life of the opened wine.
