There are lots of variables regarding the wine type, method of production, age of bottle and on and on. There are all those considerations and exceptions but for 95% of the wine that most people drink, the answer is pretty simple. Three (3) days. Around here, we keep wines up to 3 days after the bottle has been opened. Once a bottle of wine is opened, the oxygen in the air starts a process that initially softens the flavors and opens up the aromas of the wine.
How long will wine keep once the bottle has been opened? This may be the one wine question I hear most often; and the short answer, I'm afraid, is, not very long.. Wine, like fresh fruit, is perishable, and air is its enemy. Once you've taken out the cork and exposed the liquid to oxygen, it starts to deteriorate fast.
