How long can 42 liquor be stored and how many years can 42 liquor be stored?

Long-term storage is possible. After the liquor is sealed, some sealed places can be stored for a long time, and the general storage time is 5 to 10 years.

According to national regulations, low-alcohol liquor, both ethanol.

Beverages with a content of less than 10% must have an expiration date.

Target. Usually consumed liquor, alcohol content.

Liquor greater than 10% can be exempted from the expiration date. So in a normal sense, the liquor we see has no expiration date. But this does not mean that it can be stored indefinitely.

Chinese baijiu has a compound aroma with esters as the main bodyIt is a variety of liquors made from koji and liquor mother as saccharification starter cultures, and using starchy (sugar) raw materials through cooking, saccharification, fermentation, distillation, aging and blending. Strictly speaking, a blend of edible alcohol and spices cannot be regarded as liquor. The liquor is mainly concentrated in the upper reaches of the Yangtze River and the Chishui River.

The basin of Guizhou Renhuai, Sichuan Yibin, Sichuan Luzhou.

The Triangle is home to the world's largest and best quality distilled spirits.

The production area is Mao Wulu, which is one of China's three famous liquors, and its liquor industry cluster.

Carry half of China's liquor industry.

Refer to the above; Encyclopedia - liquor.

Baijiu is a food with no expiration date, as long as you seal the container and put it in a cool and dark place.

Liquor has no expiration date.

Beverages with an alcohol content of 10% or more are exempt from the expiration date. This is because microorganisms that are harmful to food quality cannot grow and multiply in a 10% alcohol solution.

The alcohol content of high-grade liquor is relatively high, generally between 41 and 55 degrees, and some are as high as 65 degrees. Even low-alcohol liquor is between 20 and 38 degrees. In this alcohol content range, it is difficult for microorganisms to survive, and there will be no deterioration caused by microorganisms, so the liquor can not be marked with an expiration date.

Storage of liquor.

Among the various flavor types of liquor, the sauce-flavored liquor is used.

It is most resistant to storage because its composition is relatively stable once formed. However, it is not absolute, and sometimes the alcohol will be emitted and the taste will become weak due to the container.

In addition, freshly produced wine is not necessarily the best to drink, and it needs to be stored for a period of time. During storage, the alcohols in the wine react with organic acids.

Esters with a special aroma are produced, so some wines will be more fragrant after a long time. Esterification in wine.

Quite slowly, fine wines generally need to be stored for three or four years, or even longer.

The above content reference: People's Daily Online - Liquor has no expiration date.

The freezing point of 42 degrees liquor should be around -25 degrees Celsius.

A 60-proof liquor is about -80 to freeze.

The current standard liquor has a general degree of 28 degrees, 33 degrees, 35 degrees, 38 degrees, 39 degrees, 40 degrees, 43 degrees, 45 degrees, 48 degrees, 50 degrees, 52 degrees, 53 degrees, 56 degrees, 60 degrees, and 68 degrees.

The degree of liquor is not and cannot represent the quality and flavor of the liquor.

The freezing point of alcohol is -117 degrees, and 60 degrees of liquor is about -80 degrees to freeze, which is generally not up to this temperature. You can try putting 60% liquor in the refrigerator, it doesn't freeze.

The freezing point of ethanol is lower than that of water, so it is not easy to freeze in winter, the freezing point of pure ethanol is -117 °C, and the freezing point of ethanol aqueous solution is also different according to the different ethanol content, and the freezing point of 40 degrees liquor should be about -25 °C.

Alcohol freezing should be -117 degrees, and the freezing point of liquor is different according to the degree, generally the height of liquor should be about -80, and the lower the degree, the easier it is to freeze. In general, liquor above 46 degrees will not freeze even in cold areas.

At the moment, it's about 10 degrees below zero.

Liquor contains a lot of alcohol, and alcohol has the effect of sterilization and disinfection, so it can effectively extend the shelf life of liquor, so the liquor with a storage time of 10 years can also be drunk.

In addition, the older the liquor, the more fragrant it becomes. After the peak period of liquor aging, only the situation is getting worse, just like the beauty also has a twilight time, and then it gradually becomes old and yellow, and enters a period of degradation. Therefore, baijiu also needs to be drunk at the right time to taste its peak flavor.

Moreover, when storing liquor, it is necessary to find a cool, quiet corner for storage, and to avoid strong or abnormal odors affecting the liquor.

42 degrees wine will freeze at around -25 °C, because, the freezing point of alcohol is -117 °C, and the freezing point of its aqueous solution is also based on ethanol.

The content varies depending on the content, and the 60-proof wine freezes at about -80 degrees Celsius. Therefore, in general, wine above 42 degrees, even in cold areas, the wine will not reach the freezing point and freeze.

For example, the pure ethanol content in 100 ml of wine is 10 ml, and the alcohol content of this wine is 10 degrees, but the capacity increases and decreases with the temperature. China's regulations are to detect at a temperature of 20. That is, at 20 hours, how many milliliters of pure ethanol content in 100 milliliters of wine is the alcohol content of the wine.

Chinese liquor has a compound aroma with esters as the main body, koji and liquor mother as saccharification starter agents, and starch (sugar) raw materials are used to brew various types of liquor through cooking, saccharification, fermentation, distillation, aging and blending.
