There are relevant provisions in the national standards, and the shelf life can be exempted if the alcohol content is greater than or equal to 10vol%.
Liquor has no shelf life, that is to say, no matter how long it takes, it must meet the marked quality standards, which is actually not in line with objective laws. During the storage of liquor, alcohols in liquor will react with organic acids to produce a variety of esters, all of which have a variety of special aroma. Because the esterification reaction of wine is quite slow, high-quality wine generally needs to be stored for three or four years or even longer. But when the esterification reaction reaches a certain level, it will tend to be balanced and stop. If it continues to be stored, it will reduce the alcohol content, weaken the taste and increase the volatilization loss. The general trend of liquor storage is high acid and low ester, and the ester content decreases by 30-50% in five to eight years. Bottled wine is usually stored for 3-5 years, which is too long. First, the alcohol content will decrease, and second, some components will decompose (which is unqualified according to the current national standards). In particular, some middle and low-grade liquors are blended with flavoring agents, which can not be stored for a long time. Otherwise, the wine will become bitter and tasteless.
How many years can liquor be stored? In people's impression, the longer the liquor is stored, the more fragrant it tastes. Is that really the case? Experts said that this is a misunderstanding, and wine has the same shelf life as other commodities.
Relevant persons said that not all wines can be preserved indefinitely. For example, yellow rice wine, wine, red wine and fruit wine all have a shelf life, and it is best not to drink after the shelf life. In addition, people's understanding of aged wine is wrong. Real "aged wine" refers to wine brewed and stored in sealed barrels, not wine sealed in bottles at home. It is best to drink bottled wine within three years. If it is stored for too long, even if it does not deteriorate, it will cause problems such as reduced alcohol content and weak wine taste.
How many years can you drink pure grain puree liquor with an alcohol content of 30 degrees? 30 degrees is puree, not white wine.
It is not recommended to store liquor of this degree.
Liquor of 30 degrees is considered as low-alcohol liquor. If the alcohol content is stored for too long, the acid will increase and the ester will decrease.
Of course, it will not deteriorate after a long storage time, but the taste will be reduced and the smell will be improved.

The acidity value is between 0.45- 1.5.
