How much does wine last after opening?
A quick and simple list of notes to consider when we want to keep part of the wine for later (shame on you, though…)
Sometimes we open a wine bottle and don’t finish it, so then the question arises: how long can I keep this wine if I already opened the bottle?
To answer this question, it’s necessary that we know some things.
The ideal thing in these cases is to have a vacuum pump, which would eliminate the oxygen that exists in the empty space inside the wine bottle to keep it from oxidizing.
Different type of vacuum pumps
The process of oxidizing is slowed down by cold, which is why once the bottle covered with the vacuum pump accessory, it should always be put into the refrigerator.
It is also good to keep in mind that not all wines last the same length of time. Any wine lasts a minimum of one day; but if we’re talking about white wines, they don’t last more than 2 or 3 days, pinks last 3 days, and sparkling wines are barley able to survive a day and a half (especially because of their gas bubbles, which start dissolving. Red wines with a robust body are able to last as long as 5 days.

Why not just cover the wine with its cork and let it be?
When we can’t control it, oxygen is a wine’s worst enemy. Let’s imagine that, in a bottle in which half its content has been drunk, this empty space is full of oxygen, which will cause the wine to start oxidizing in the next few hours.
How do we know if the wine was kept in good conditions?
To know if the wine was not stored correctly and became defective, it is oftentimes enough to identify its unpleasant aroma or its unpleasant taste (usually, its acidity increases notably).
If its aroma doesn’t give us much information, we’ll be able to tell once we try it; our palate will be the ultimate determinant of whether we still like it or not.
