How long is the shelf life of liquor?

Liquor has a shelf life, which is generally indicated on the package. Liquor can be preserved for a long time, but the taste will become worse after the shelf life. It is recommended to drink it during the shelf life. The alcohol content of liquor sold in the market is basically above 10%. Generally, harmful microorganisms cannot grow and reproduce in it, and it is difficult for microorganisms to survive, so there will be no deterioration caused by microorganisms, so liquor can be preserved for a long time. Although the microorganisms that lead to quality deterioration cannot grow, it does not mean that the composition of liquor itself will not change. Low-alcohol liquor and Fen-flavor liquor below 40 degrees usually undergo ester hydrolysis after being stored for more than 3 years, resulting in dull taste, and some may have astringent taste.

Generally, it is fermented from solid pure grain with an alcohol content of about 53. Maotai-flavor liquor can be preserved for a long time, and its taste will not deteriorate, and it may be better.
