How many years can the liquor last, and how long can the liquor generally last

Liquor has no expiration date.

According to the provisions of the national "General Principles for the Labeling of Prepackaged Food" (GB7718-2011), beverage wine 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 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.

Liquor has no expiration date.

Because microorganisms harmful to food quality are difficult to grow and reproduce in 10% alcohol solution, and under normal circumstances, the alcohol content of high-alcohol liquor is mostly between 41 and 55 degrees, generally not more than 65 degrees, and even low-alcohol liquor is between 20 and 38 degrees, so liquor generally has no expiration date.

Although baijiu has no expiration date, it does not mean that the longer the baijiu can be stored, the better. Generally, after five years, the taste of ordinary flavor liquor will become lighter and the aroma will weaken. The longer the storage time of the strong flavor liquor, the worse the quality of the liquor will be.

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

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.

Sealed liquor is usually attacked and says that there is no expiration date.

The more the wine is aged, the more fragrant it becomes, but there are some details that must be paid attention to when it comes to storage.

dao。First of all, it must be sealed. It can't be a bottle of wine that is opened and drunk some, and the rest is saved.

In this way, even if it is a high-grade sake, it will not become more fragrant as it ages. The sealing is mainly to prevent the volatilization of alcohol in the wine, if the storage environment is not tight, it may be stored that a bottle of wine is only left after volatilization.

How to store liquor:

1. The temperature of the liquor storage environment is best maintained at a constant temperature of 12 15. Therefore, if the wine storage environment can be maintained at a certain temperature of 5-20 degrees, it is also ideal to maintain a change of 2 degrees.

2. It is ideal to place the liquor flat to maintain its moisture, because the liquor will have precipitation after being stored for a long time, and the precipitation will gather at the bottom of the bottle if it is placed flat or the bottle mouth is slightly tilted upward.

3. The ultraviolet rays in the light are very damaging to the liquor, and it is also one of the culprits that accelerates the oxidation process of the liquor, so the liquor that you want to preserve for a long time must be placed in a place away from light.

Ordinary liquor can be left for 3-5 years.

If the alcohol is stored for too long, it is volatile, and even if it is not opened, it will be volatilized by natural oxidation. Liquor with a low degree should not be left for a long time, although there is no expiration date, it is advisable to drink it as soon as possible. Generally speaking, high-quality liquor with no additives will be stored for a longer time.

High-quality liquor must have a proper shelf life. Lu type wine should be stored for at least 3 6 months, and more than one year; The storage period of Fen type liquor is about one year, and Mao type liquor requires storage of more than three years. The alcohol content is generally above 40 degrees, and below 40 degrees is low alcohol alcohol.

In China, the wine culture has a long history, and wine has always been people's favorite throughout the ages, especially liquor, which every family will keep. So how many years can liquor last? How to preserve liquor? Now let's talk to you about the preservation method and age of liquor.

1. Liquor can be stored for several years.

In fact, as long as it is stored properly, without air leakage, outgassing or volatilization, it is no problem to store it for a few years to decades or even hundreds of years, and the longer it is stored, the more mellow its taste will be, so it makes sense why many wines should be treasured for decades, or even centuries.

2. What are the preservation methods of liquor?

1.Store at room temperature.

When purchasing a return sake, it can be stored at room temperature without opening it. Be sure to store it at room temperature, avoid direct sunlight, have a balanced temperature, and store it in a cool and ventilated place.

2.Cellar preservation.

The temperature in the cellar is relatively balanced, and it will be lower than the average outdoor temperature, and the inside is relatively dry, so it is also good for storing liquor. Bright and noisy.

The drinking life of liquor is generally about 15 years.

The high number of liquor is suitable for storage, but the best drinking life is about 5 15 years, if it is more than 15 years of liquor, try not to drink, so as not to bring serious damage to the liver, try to use this liquor as the base liquor, and then add new liquor to blend, the taste of the wine will be better.

If you want to store alcohol, you should put it in an appropriate environment, control humidity, temperature and light, etc., because alcohol molecules are very active and will be more active when exposed to high temperatures, so it should be placed in a relatively low temperature environment, and at the same time maintain a certain stability.

The shelf life of liquor

After a longer period of storage, the quality of baijiu will become warm and mellow, so some people believe that the older the baijiu, the better. In fact, not necessarily, although liquor has no expiration date, but during the storage of liquor, the alcohols in the liquor will react with organic acids to produce a variety of esters, and all kinds of esters have a variety of special aromas.

Because the esterification reaction in the wine is quite slow, therefore, high-quality wine generally needs to be stored for three or four years, or even a little longer, but the esterification reaction will tend to balance to a certain extent, and there will be a stop state, if it continues to be stored, the alcohol content will be reduced, the wine taste will become lighter, and the volatile loss will also increase.

In particular, at present, some mid-range and low-grade liquors have added flavoring agents in the blending process, and this kind of liquor cannot be stored for a long time. Otherwise, the liquor will become bitter and greasy, so the liquor is stored for a proper time, not the older the better, the liquor is volatile, leakage, and the temperature will overflow.
