Does unopened liquor have an expiration date?

After a long period of storage, the quality of the liquor will become warm and mellow. Therefore, some people believe that the older the liquor, the better. Actually, not necessarily.

Although liquor has no expiration date, during the storage of liquor, the alcohols in the liquor will react with organic acids to produce a variety of esters, and each ester has a variety of special aromas. Because the esterification reaction in wine is quite slow, high-quality wine generally needs 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.

Liquor generally has no expiration date! Just seal it well! Just the right temperature!

After the liquor is opened, the liquor and the air come into contact, it will begin to react, seal the bottle in time and put it in a low temperature place, it can be stored for about 7 days, if it is not stored properly, the alcohol volatilizes for a long time, and it will lose its original taste.

All wines have an expiration date, and it is necessary for wine and liquor to be more fragrant the older they age. Temperature, wine, carrier, humidity, quality and degree are all very particular. For example, ordinary bottled liquor, in the process of storage, the alcohols in the liquor will react with organic acids to produce esters, and the alcohol will slowly volatilize, and the taste of the liquor will become lighter, especially at present, some liquors have added flavoring agents in the blending process, and this kind of liquor cannot be stored for a long time.

Otherwise, the wine will become bitter. The longer a regular bottle of wine is left unattended, not only will the flavor disappear, but bacteria will multiply and the wine will become sour. The smell is also not good.

In terms of the conditions of our ordinary people's homes, we still do not have the conditions for storing fine wine.

Not all wine can be stored indefinitely, such as rice wine, wine, red wine, fruit wine, etc. have an expiration date, and it is better not to drink it after the expiration date. In addition, the real "aged sake" refers to the sake brewed and stored in sealed barrels, not the sake sealed at home, and it is best to drink the sake within three years after bottling, and even if it does not deteriorate for too long, it will cause problems such as lower alcohol content and lighter flavor.

Liquor has no expiration date. Drinking liquor above 10 degrees can be without marking the expiration date, while general liquor is above 10 degrees, so there is no expiration date. It is generally recommended to store for 3-5 years.

According to the regulations of the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China and the Standards Committee, drinking liquor above 10 degrees can be without marking the expiration date, while general liquor is above 10 degrees, so there is no expiration date. The alcohol itself has the effect of sterilization and antiseptic, and it is difficult for bacteria and other microorganisms to survive, which means that the liquor will not deteriorate if it is stored for a long time, and naturally there is no need to mark the shelf life.

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

It is better to maintain the temperature of the liquor storage environment at a constant temperature of 12 to 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.

Is it better to store liquor for as long as possible?

After a long period of storage, the taste of baijiu will become warm and mellow. This is because, over time, during storage, the alcohols in the wine will react with organic acids to produce a variety of esters (aroma reaction), which have a special aroma and make the wine more fragrant.

Does the fact that liquor has no expiration date mean it will never expire? Not necessarily! Not all wines are suitable for long-term storage.

Because there are relevant provisions in China's standards, beverages with an alcohol content greater than or equal to 10vol% can be exempted from labeling the expiration date.

The degree of liquor is generally above 10 degrees, so the liquor is not marked with a shelf life, and the relevant national quality inspection departments are also recognized.

Liquor itself has the conditions that do not mark the shelf life: 1. Alcohol can be sterilized.

After scientific experiments, some harmful microorganisms cannot grow and multiply even in a liquid with an alcohol content of 10%, and cannot produce harmful substances.

2. The internal structure of the liquor with high degree is relatively stable, the chemical change will be very small, and the sealing technology is now developed, so there is no need to mark the shelf life.

Baijiu is one of the representatives of traditional Chinese liquor culture and has been loved by people since ancient times. Compared with other liquors, baijiu does not have a definite shelf life, because baijiu undergoes multiple processes and links in the brewing process, so that the microorganisms, yeast and other substances in the liquor are effectively killed, thereby extending the shelf life of the liquor.

Baijiu has been brewed for thousands of years, and its brewing process has been continuously explored and practiced by many generations, and a complete brewing process has gradually formed. In the brewing process of liquor, a large number of raw materials such as koji, bran, and bran are used, which are rich in protein and carbohydrates, which are the ideal nutrients for micro-Siheng organisms and yeast**. In the brewing process, koji bacteria and yeast bacteria interact and decompose to break down the sugars in the raw materials into alcohol and carbon dioxide, and also decompose the harmful substances in the microorganisms and yeast, so as to effectively kill and preserve freshness.

In addition, the alcohol content of baijiu is usually above 40 degrees, and this high alcohol concentration is also one of the important reasons for the long shelf life. The high concentration of alcohol on the ground can effectively kill the bacteria and viruses in the wine, and avoid the deterioration and spoilage of the wine. At the same time, adding an appropriate amount of sulfur to the liquor can play a certain preservative role and further extend the shelf life of the liquor.

Although there is no definite expiration date for baijiu, it does not mean that baijiu can be stored for a long time. Prolonged storage will gradually separate the alcohol and moisture in the wine, resulting in a decrease in the taste and quality of the wine. Therefore, when storing liquor, the liquor should be stored in a cool, dry, and ventilated environment as much as possible, avoiding direct sunlight and high temperatures.

At the same time, it should also be avoided to store with other items with off-flavored items, so as not to affect the taste and quality of the wine.

In short, there is no clear shelf life of baijiu because it has undergone multiple processes and links in the brewing process, so that the microorganisms, yeast and other substances in the liquor are effectively killed, thereby prolonging the shelf life of the liquor. However, prolonged storage will lead to a decrease in the taste and quality of the liquor, so there are some details that need to be paid attention to when storing the liquor to ensure the quality and taste of the liquor.

In a general sense, liquor has no expiration date. The quality of X0D X0A varies over time due to different packaging and storage conditions. If the packaging of ordinary bottles is stored for a long time, the quality of the wine will deteriorate.

However, it does not affect the citation. Because the main components of liquor are water and ethanol. There are almost no nutrients, so they do not spoil easily.

Even in a 10% alcohol solution, microorganisms cannot grow and multiply and produce harmful substances; Baijiu has a high alcohol content and very little chemical change, so it is possible not to indicate the expiration date, but the wine with a low alcohol content may not. The microorganisms in the wine are easy to 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.

Some. The claim that wine has no expiration date is a misinformation. The longer the wine is in the cellar or oak barrels, the better, but after leaving the factory, the storage conditions are different from those in the cellar or oak barrels, and in fact, there is a shelf life.

The shelf life of beer is 3 months, and after opening the bottle, it must be drunk on the same day; Red wine, wine, etc. have a long shelf life, and some dry red wines can be left for about 10 years; For liquor, it depends on the alcohol content and the manufacturer, and the liquor produced by the brand manufacturer above 40 degrees is not a big problem for a longer time. If it is a liquor produced by a small distillery, some of which are mixed with spices, flavors and alcohol, it cannot be drunk itself, let alone have an expiration date. As for the saying "the older the more fragrant", it refers to the sake brewed and stored in sealed barrels, and the taste of the wine can be distilled for a long time, and there is no shelf life for the distilled spirit, but if it is stored at home for too long, the alcohol and aroma will evaporate.

In addition, distilled spirits no longer age after bottling. Therefore, it is better to drink alcohol at home as soon as possible. It can fade.

Hope it helps.

Liquor is allowed to be stored for a long time without failure to deteriorate. Baijiu itself has a strong bactericidal ability. So there is no expiration date.
