High-strength liquor has a maximum concentration of 65 degrees. The alcohol content is above 41 degrees, usually above 55 degrees, and generally does not exceed 65 degrees to be considered high alcohol.

The chemical component of wine is ethanol, which generally contains trace amounts of fusel alcohols and esters. The concentration of edible liquor is generally below 60 degrees (i.e. 60) (a few have more than 60 degrees). Liquor is purified by fractionation to Alcohol above 75% is medical alcohol, and alcohol purified to above 99.5% is absolute ethanol. Liquor is brewed from grain through fermentation.

Storage of liquor:

Liquor above 50% is suitable for long-term storage. High-strength liquor is generally brewed from pure grains. It has less volatile substances and the wine body is not easy to deteriorate and is suitable for long-term storage. Low-alcohol liquor below 50 degrees has a lot of aroma components added, and the aroma will gradually dissipate as time goes by. At the same time, low-alcohol liquor contains many volatile substances, and the wine body is easy to deteriorate.

Generally speaking, the relative humidity is about 70%. If the humidity is too high, the 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 lower alcohol content. It is better to store in an environment that avoids light and has suitable humidity and temperature. During the storage process, you should "look more and move less".

It is also very important to choose liquor suitable for long-term storage. For example, high-strength liquor, complete sets or "concept liquor" with special significance are more suitable for collection.
