I believe that many people have encountered such a problem. After opening a bottle of fine wine, it is impossible to drink it all at once. How to store the remaining wine?

Since wine will accelerate oxidation and change its flavor when exposed to a large amount of air, we should try to avoid continued contact between wine and air. There are four common practices, but they are all stopgap measures.

The first is to put the cork back into the mouth of the bottle and put it upright in the refrigerator or wine cabinet. However, a wine cooler is naturally a better place to store than a refrigerator with more or less odors.

The second is to change the large bottle to the small bottle. Pour the unfinished wine into a small clean and odor-free container and store it tightly, which can reduce the contact area between the wine and the air, thereby slowing down the evolution of the wine.

Third, use a vacuum pump. Extract the air from the wine bottle to reduce the contact between the wine and the air.

Fourth, inject inert gas. Conditional drinkers can also use professional tools to inject inert gas, such as nitrogen, into the wine bottle.

But even so, the wine can't be kept for too long after opening.
