Once a bottle of wine is opened, it starts to oxidize, and the flavor and aroma begin to degrade. However, there are several ways to slow down this process and keep the wine fresh for a few more days:
Recork or seal the bottle: Replace the cork or seal the bottle with a wine stopper to prevent air from entering the bottle.
Store it in the refrigerator: Place the wine bottle in the refrigerator to slow down the oxidation process. White and rosé wines should be stored in the fridge, while red wines can be kept at room temperature or slightly cooler.
Use a vacuum pump: A vacuum pump can be used to remove the air from the bottle and create a vacuum seal.
Use a wine preservation system: There are wine preservation systems available that use inert gas, such as argon or nitrogen, to replace the air in the bottle and create a protective layer.
Finish the bottle: If all else fails, you can always finish the bottle. Invite some friends over, enjoy a glass of wine, and savor the moment.
