How long is the shelf life of liquor and how long is the shelf life of liquor?

There is no shelf life for liquor, because China's General Administration of Quality Supervision, Inspection and Quarantine and the Standards Committee of the Standards Committee stipulate that drinking liquor above 10 ° can not be marked with the expiration date, and the degree of liquor is basically above 10 °. However, the best drinking time for liquor with different sweat needs to be different, for example, highly pure grain liquor needs to be stored for 20 to 30 years before the best quality of the liquor can be achieved.

This kind of liquor develops a relatively slow aroma, and it often takes four or five years of storage to develop a strong aroma. Generally speaking, low-alcohol pure grain wine does not need to be stored for a long time, usually only needs to be stored for 4 to 5 years, and if it is stored for too long, it will affect its drinking taste. The liquor blended with alcohol will not have aroma reaction when stored for a long time, and its best drinking period is less than 3 years.

We know that generally everything you eat will have an expiration dateLiquor has no expiration date, but during the storage of wine, the alcohols in the wine will react with organic acids.

A variety of esters are produced, and all esters have a variety of special aromas. Due to the esterification reaction in the wine.

It's quite slow, so good wines generally need to be stored for three or four years, or even a little longer. However, when the esterification reaction reaches a certain level, it will tend to be equilibrium and stop state, and if it continues to be stored, the alcohol content will be reduced, the wine flavor will become weaker, and the volatilization loss will also increase. In particular, some mid-range and low-grade liquors are added with flavoring agents during the blending process, and this kind of liquor cannot be stored for a long time.

Otherwise, the wine will become bitter and greasy. Therefore, there is also a proper amount of time for the storage of liquor, and it is not better to get older.

Everyone knows that alcohol is meant to kill bacteria. According to many scientific experiments, some harmful microorganisms do not produce harmful substances even if they have an alcohol content of 10%.

After the degree of liquor is too high, it is difficult for the liquor in the bottle to undergo chemical reaction, and the sealing is good now, so the shelf life of the liquor should not be marked.

The degree of liquor is too low to preserve, even if the bottle of liquor is well sealed, it cannot be stored for too long, because after a long time, a chemical reaction will occur due to the volatilization of alcohol, resulting in the taste of liquor.

If you want to keep it all year round, the ideal environment for all wines is constant temperature, preferably around 10-15 degrees, constant humidity, dark conditions, these are only available in professional cellars or natural cellar caves.

But the condition of the spirits can be a little worse, for example, it is displayed in the family condition.

It will be stricter for brewed wine, and for ordinary consumers. It can be placed under the bed at home, which is dark and undisturbed.

Seal tightly and store in a cool place. The alcohol content of the aged sake will decrease and become viscous, but there are some people who like this kind of sake, and it is not considered a decrease in quality. The alcohol is mainly lost through the gaps in the cork, and in the past, the jar was sealed with mud (of course, there was a cloth under the mud), so you can try it.

The composition of liquor is particularly complex, and people have also learned that the substance that exudes mellow in liquor is ethyl acetate after years of research.

However, the content of ethyl acetate in the newly brewed liquor is very small, but there are a lot of aldehydes and acids in the liquor, which is what causes people to stab their throats when drinking liquor.

After the liquor is stored for a long time, the aldehydes and acids in the liquor will volatilize and oxidize, producing a large amount of ethyl acetate, so people often say that the liquor is also alive, although the change is slow, but it changes every day, and the high-quality liquor will be stored for decades before it is very mellow, and the taste will be better.

It takes 5 years from the beginning of brewing.

Some liquors will add some flavors or spices when brewing, so after a period of storage, these flavors will change, and the taste of the liquor will also change.

Liquor has no expiration date.

According to the provisions of the national "General Principles for the Labeling of Prepackaged Food" (GB7718-2011), beverage wines with an alcohol content greater than or equal to 10% can be exempted from the labeling 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 there are also cavities 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 problem of microbial deterioration, so the liquor does not need to be marked with an expiration date.

The shelf life of liquor varies from 5 to 10 years1. Although some people think that baijiu has no expiration date, in fact, baijiu has a drinking period, that is, the best drinking range, and the taste is the best2. Different brands and different flavors of liquor have different tasting periods, some of them taste the best when they are left for 1 year and then drink Minshan, while others take 3 to 5 years, or even longer2.

Low-alcohol liquors become more unstable the longer they last, while strong flavor and sauce-flavored liquors are suitable for long-term storage3. Therefore, the shelf life of liquor is not fixed but is affected by a variety of factors.

Baijiu has no expiration date, and the longer the storage time, the better. Ordinary liquor is stored for five years, and the stronger the flavor liquor is, the worse it gets, and the storage time of sauce-flavored liquor should not be too long. Aging, on the other hand, is that the longer it is preserved, the more mellow it becomes.

For example, if Moutai is stored in the cellar, the molecular transformation is more stable, so the ingredients in the wine are richer.

Baijiu has no expiration date, and it does not mean that the longer the liquor is stored, the better, which is subject to storage conditions. Generally, after five years, the taste of ordinary flavor liquor will become lighter and the aroma will weaken. On the contrary, the longer the liquor is stored, the worse the liquor quality will be.

Sauce-flavored liquor can be stored in the cellar of a professional manufacturing factory, and can be stored for a long time under certain humidity, temperature, soil, and simple conditions containing certain beneficial bacteria, but the time should not be too long, and it is recommended to drink it as soon as possible after opening.

The longer the aging time, the more conducive to the formation of various molecules in the wine, enhance the affinity of the molecules, and make the wine more mature and mellow. For example, Moutai is stored in the cellar, so that the transformation of acid, fat and alcohol is more stable, and the ingredients in the wine are richer.
