The reasons why wine is not banned are: tannins can clarify wine and promote appetite.

It is necessary to use a small amount of wine (200 ~ 500 ml) to test and accurately determine the amount of gelatin and tannin to clarify the wine. For the convenience of home brewing, it can also be clarified by egg white. The method is to beat the egg white into foam, fully stir and mix it with a small amount of wine, then add it to the wine, fully stir and stand until the wine is clear and transparent, and discard the precipitate.

Precautions for drinking wine

The normal indoor temperature can't reach the drinking temperature, so it is generally used to cool the wine and put it in the refrigerator in advance to reduce the temperature of the wine. Pay attention to the wine stored in the refrigerator for a long time, so as to avoid the freezing of the wine body and affect the taste.

Wine sobering up is an important link, which can reduce the cork taste and soften tannins in wine and enhance the aroma in wine. The hangover time should be judged according to the time that wine can be aged. A bottle of high-grade wine with long aging time needs hangover 1-2 hours for drinking in advance.
