The older the vintage, the higher the price, why doesn t baijiu expire?

In life, many wines are higher in age, which is what we often call old wines. Many old wines have even far exceeded their market value, thus becoming a kind of collectible. In particular, some of the more expensive old wines** have been turned over well.

Because some precious wines have a good seal and high alcohol content, they will not expire even if they are stored for many years, but after a long period of storage, the wine will undergo a wonderful change and become more and more fragrant.

The reason why liquor does not expire is first and foremost because it is well sealed. The liquor does not expire first because the sealing is very good, and a bottle of liquor that has been opened will expire anyway, so it is said that the liquor does not expire because the bottle of liquor is very well sealed; Secondly, the disinfecting effect of alcohol. The alcohol contained in the liquor has the effect of sterilization and disinfection, which also ensures that the liquor will not expire in a sterile environment for a long time, but not all liquor will not expire, and the liquor with too low degree will also expire; Finally, the alcohol concentration is high.

Generally speaking, only liquor with a high alcohol content will expire, and liquor with a relatively low alcohol content can easily expire. For example, the beer we often drink generally has a short shelf life. <>

1. Good sealing. It doesn't matter if it's liquor or any other food. Only with good sealing, the longer the storage time, and the better the sealing, the longer the storage time, which is why baijiu can be stored for a long time.

The liquor has a very good seal after canning, so it is not easy to expire. <>

Second, the anti-virus effect of alcohol. Alcohol has a disinfecting effect, which is common knowledge that we all know. Therefore, the liquor in the bottle can be automatically sterilized and disinfected, and there will be no bacteria in the liquor that cause the liquor to expire and deteriorate, so the liquor will not expire if stored for a long time. <>

3. High alcohol concentration. Not all liquor will not expire, and most of the liquor that will not expire has a high alcohol content so that it can kill bacteria. And some liquor with low alcohol content will expire. Therefore, not all liquor will become more and more fragrant.

Do you think liquor expires?

Liquor does not expire mainly because alcohol contains the effect of sterilization and disinfection, which is not easy to spoil, and its chemical composition is relatively stable and can be stored for a long time.

Because baijiu does not ferment, and the place where baijiu is stored is generally in a cold and dry environment, baijiu will not expire.

The more you put the better the wine, the more you want to brew pure grain, the sauce-flavored liquor is more in line with this, I usually drink Honghualang, the longer the storage time, the stronger the sauce aroma.

Liquor will not expire and the production process of the production materials have a certain relationship, liquor is brewed from grain, the longer the storage, the better the taste, the alcohol concentration in the liquor is very high, can play a role in sterilization, so the liquor will not expire.

This is because the liquor will become very mellow after being stored for a long time, and the brewed alcohol can play a sterilizing role, so it will not expire.

Because liquor is made from grain, there is a saying that wine is still fragrant when it is old, so the longer the liquor is left, the better the taste will be.

1. The main ingredient of wine is ethanol, which has a strong ability to coagulate proteins, and microorganisms are basically dao

It cannot survive in the sake version, so it can be stored for a long time.

2. It is a paradox that the older the wine, the better, the ancients did not understand science, so they spread falsehoods. In fact, after the liquor is stored for a long time, some ethanol will be esterified into ethyl ester, and the flavor will be greatly reduced. In addition, no matter what container you use to store it, it can't stop the volatilization of ethanol, and if you leave it for a long time, the taste of the wine will become weaker, which will also seriously affect the taste.

Baijiu generally does not have an expiration date, but this does not mean that the longer the baijiu is stored, the better, and the ordinary flavor of the white.

After 5 years, the taste of zhi wine will become lighter and the aroma will be weakened; Sauce-flavored aged wine is a good wine, but whether a strong aromatic wine that has been stored for many years is still inconclusive and controversial. Low-alcohol liquor, especially liquor below 32 degrees, is more likely to cause performance changes the longer it is placed, and over time, it will lose the inherent characteristics of liquor. In this regard, the state has strict regulations, requiring that beverages with ethanol content below 10 must be marked with a shelf life.

Summary. Dear, liquor will not be priced according to the length of the year it is stored. Many long-established liquor manufacturers produce vintage liquor, which is genuine, and its ** will naturally be higher.

However, at present, not all vintage liquors on the market are worthy of the name, and some of the first-class aged liquors that are advertised by manufacturers as having a long history and strong cultural color, such as those with the logo of "ten years of aging" or even "thirty years of aging", are mostly just a concept and are not completely consistent with the preservation time. For example, the 30-year age on the package does not mean that all the contents of the bottle are stored for 30 years, but only that some of the wine in the bottle has been aged for 30 years.

Hello, I am Life Answerer Pepsi Know-it-all k2, I have served 2580 people, I am happy to serve you, and the teacher is answering for you.

Dear, no, although there is no expiration date limit for liquor, the longer some liquor is stored, the taste will become lighter, the fragrance will be weaker, and there is basically no collection value. Storing liquor for too long is not good for the quality of the liquor, and it will also increase the volatilization loss of alcohol. Generally, the shelf life of ordinary flavor liquor is 5 years, while the aroma of strong flavor liquor will slowly lose after 3 years, so not all liquor is more valuable the longer it is stored.

Summary. Dear, isn't the older the vintage, the more valuable it is.

Only liquor with a high degree of alcohol and made from pure grains can ignore the expiration date, while liquors with a degree between 30 and 40 degrees, as well as liquor blended with alcohol or using additives, have a shelf life.

And these shelf-life wines are obviously not worth more than the longer they are stored.

Is liquor worth more than it is the older it is?

Dear, isn't the older the vintage, the more valuable it is. Only liquor with a high degree of alcohol and made from pure grains can ignore the expiration date, while liquors with a degree between 30 and 40 degrees, as well as liquor blended with alcohol or using additives, have a shelf life. And these shelf-life wines are obviously not worth more than the longer they are stored.

Liquor without shelf life is not necessarily more valuable the longer it is stored, some liquor is intended for everyone to drink, and they are brewed for taste, not for long-term preservation. Some liquors are for storage and cherishing, and they will be more refined when brewed, so that the longer they are stored, the more valuable they are.

Liquor is divided into three categories: one is that it cannot be stored; One is that the storage time is short, which is suitable for drinking as soon as possible; One is that the longer the storage time, the better the taste and quality, and the more valuable it will be.

The longer the storage of liquor, the better, and the quality of the liquor depends on the quality of the liquor.

There are relevant provisions in the national standard, and the alcohol content is greater than or equal to 10vol%, which can be exempted from the labeling of the shelf life.

Baijiu has no expiration date, which means that no matter how old it is, it must meet the quality standards labeled, which is actually not in line with the objective law. In the storage of liquor, the alcohols in the liquor will react with organic acids to produce a variety of esters, and all esters have 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. The general trend of liquor during the storage period is high acid and low esters, and the ester content is reduced by 30-50% in five to eight years. Bottled finished liquor is generally stored for 3-5 years, the time is too long, one is that the alcohol degree will be reduced, and the other is that some components will decompose (according to the current national standards are also unqualified), especially at present, some mid-range and low-grade liquor, flavoring agents are added in the blending process, and this kind of liquor can not be stored for a long time.

Otherwise, the wine will become bitter and greasy.

As long as you don't open the bottle, it won't expire, and the longer the better.

Does liquor expire? Under normal circumstances, is it better to leave the wine for as long as possible?

Some liquor has an expiration date, and the older it is, the better it tastes because of the contact between alcohol and air.

for the sake of oxidation.
