In fact, liquor has no shelf life. When you tear off the Chinese label on the bottle, you will find that there is no shelf life, but it will really deteriorate after a long time. The drinking period of wine is generally 3-5 years, liquor is 1-3 years, and red wine is 3-5 years. Most wines are not suitable for long-term storage, and only a few fine wines need to be stored for more than 10 years to reach the drinking period.

In foreign countries, winemakers will judge the best drinking period of wine according to their own experience and knowledge. This refers to the date when wine reaches its peak. After this date, the state of wine entered the aging period, and the aroma, taste and taste gradually lost. But that doesn't mean you can't drink it, just the taste is not as good as before.

Therefore, the preservation methods of several wines are as follows:

1, a bottle of cold storage is well sealed, and nearly a whole bottle of wine can be kept in the refrigerator for a week or even longer, but it should be noted here that the temperature of wine can not be drunk until it reaches room temperature.

2. Re-seal If it is determined that a bottle of wine cannot be completely drunk, put the cork back in the bottle as it is immediately after pouring the wine. If you can't put it back as it is, it is ok to use plastic wrap.

3. Putting oxygen vertically is also an enemy and friend for wine. When storing a resealed bottle of wine, it is necessary to ensure that the bottle is in an upright position to minimize the contact area between wine and oxygen.
