Cabernet Sauvignon How long is a bottle of wine good after it initially opened?

Once opened, a bottle of wine will typically last for about 3-5 days if it is stored properly. To preserve the wine, it should be stored in a cool, dark place, such as a wine refrigerator or a cool pantry. The wine should also be sealed tightly to prevent oxygen from entering the bottle. If you plan to store the wine for longer than 5 days, it is best to decant it into a smaller container, such as a half bottle or a carafe, to reduce the amount of air in the bottle.
