How long is the shelf life of low-alcohol liquor?

According to relevant regulations, beverage wines with an alcohol content of 10 or more are exempted from labeling the shelf life. Because alcohol has a bactericidal effect, it is difficult for microorganisms to survive and deteriorate in alcohol concentrations above 10 degrees.

According to relevant regulations in my country, beverages with an alcohol content greater than or equal to 10vol can be exempted from labeling the shelf life.

Because even in 10% alcohol solution, microorganisms cannot grow and reproduce, and cannot produce harmful substances; the alcohol content of liquor is relatively high, and above this alcohol content, it is basically difficult for fungi to survive and will not appear. There is a problem of deterioration, so there is no need to mark the shelf life. However, if the alcohol content is very low, microorganisms in the wine will easily grow and multiply, causing the wine to deteriorate and produce a sour taste. Therefore, low-alcohol wine should not be stored for a long time.

Secondly, as the saying goes, wine tastes better with age. If high-alcohol liquor is stored sealed in a suitable environment, the aldehydes and acids in the wine will oxidize and esterify, forming ethyl acetate that makes the wine more fragrant and mellow. , this kind of aged wine has no so-called shelf life. It can only be said that it tastes best when consumed within a certain period of time.

Of course, not all liquors become more fragrant with age. If low-alcohol liquor is stored for a long time, its taste will easily become lighter. It is best to drink this kind of liquor within two years.

Extended information:

"Generally speaking, the relative humidity is about 70%. If the humidity is too high, bottle caps will easily become moldy; if the temperature is between 0 degrees and 20 degrees, fireworks are strictly prohibited. . The container should be tightly sealed to prevent leakage of wine and reduce alcohol content. "Liquor experts said that it is better to store in an environment with suitable humidity and temperature, away from light, and "watch more and move less" during storage. Another very important point is to choose liquor suitable for long-term storage. For example, high-strength liquor, complete sets or special meaning "concept liquor" are more suitable for collection.

Not all liquors get better with age. If some liquors are stored for too long, they will enter the "senescence period" and lose their original flavor. Especially for light-flavor liquor, it is best not to store it for a long time, because it is easy to lose its original flavor characteristics and even develop a bitter taste. Among the various aroma types of liquor, Maotai-flavor liquor is the most suitable for storage. The best container for holding wine is a jar, because the jar itself contains a variety of minerals. Using it to hold wine can maintain the aroma of the wine for a long time, make the wine more fragrant and mellow, and promote the aging of the wine.
