When the wine is opened, the oxygen in the air enters the bottle and reacts with the wine. After the right amount of oxidation, the aroma of the wine is opened up, and the personality can be fully stretched. However, if an open bottle of wine is not drunk as soon as possible, the wine will lose its rich aroma and subsequently develop a vinegary taste. So what are some ways to preserve an open bottle of wine and extend its lifespan?

1. Refrigeration

The easiest way to prolong the life of your wine is to re-cork and store it in the refrigerator. If the remaining wine is well sealed and there is more remaining wine, it can be stored in the refrigerator for a week or more. If the cork cannot be resealed, plastic wrap can be used. Typically, red wines are kept longer than white wines by this method. Take the wine out and let it warm to room temperature before drinking it next time.

2. Replacing the container

If you have a small-capacity wine bottle, you can pour the unfinished wine into the small wine bottle and plug the bottle to reduce the contact surface between the wine and the air, thereby reducing oxidation. Although this method is a little complicated, if the replaced small wine bottle is filled with wine and resealed, it can produce a good preservation effect. When using this method, it should be noted that do not use detergents such as detergent to clean small-capacity wine bottles to avoid residual stains contaminating the wine.

3. Use a bottle opener

There are many types of corkscrews on the market that can help preserve open bottles of wine. For example, the Coravin corkscrew can pass a needle through a cork to get wine without opening the bottle.

4. Vacuum method

A vacuum device is used to remove the oxygen in the wine bottle and seal the wine bottle. But this method is not suitable for sparkling wine, because it will cause the sparkling wine to lose its bubbles. Common vacuum devices, such as vacuum pumps, can be purchased in supermarkets or wine shops.

5. Override

Use professional tools to put inert gases such as nitrogen or argon into the wine bottle to form a protective layer between the wine and the air, which can protect the wine from oxidation.
