about 3 to 5 days
Secondly, can you drink old opened wine?
A: Probably not. The unpleasant taste that you detect in a bottle of wine that has been open for more than a day or two is due to the process of oxidation. Oxidation occurs, as you might imagine, when oxygen is introduced to wine. This taste is unpleasant, to be sure, but it's not necessarily harmful to your body.
