How long is the shelf life of wine Introduction to the shelf life of wine

Yes. The reporter visited a number of supermarkets in Zhengzhou City, and found that there were many customers who chose liquor other than liquor, and after careful inspection, it was found that Shaoxing Huadiao, Daughter Hong, Huijishan and other major brands of rice wine are marked with a shelf life on the packaging, and the shelf life of these rice wines is generally 24 months to 60 months, and there are also a small number of jar rice wines with a shelf life of 6 years.

The shelf life of red wines such as Changyu, Great Wall and Dynasty is 5 to 10 years, and most of the required storage environments are room temperature, ventilation, coolness, dryness, etc. The shelf life of some fruit wines and rice wines is usually 2 to 3 years, and some lower alcohol drinks have a shelf life of only 10 to 12 months. Baijiu only emphasizes the storage environment, and generally does not indicate any expiration date.

All beers are marked with an expiration date, which is usually one year.

1. The shelf life of beer is 3 months, and after opening the bottle, it must be drunk on the same day.

2. Red wine, wine, etc. have a long shelf life, and some dry red wines can be stored for about 10 years.

3. Liquor: The more it ages, the more fragrant it is, which refers to the wine brewed and stored in sealed barrels, and the taste may become lighter after being bottled for a long time. Baijiu generally has no shelf life, but this does not mean that the longer the liquor is stored, the better, after 5 years of ordinary flavor liquor, the taste will become lighter and the aroma will be weakened; Sauce-flavored aged wine is a good wine, but whether the strong flavor 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 stored.

1. Because of the esterification reaction in liquor.

It's very slow, so generally the better wines need to be stored for 3 to 4 years, and some may be a little longer.

2. However, the esterification reaction in some liquor will also reach equilibrium, the esterification reaction will stop, and if it continues to be stored, the alcohol in the liquor will also become weaker, and the taste of the liquor will not be so good. Especially in the process of blending, some medium and high-end liquor will more or less add some flavoring agents, and the storage time of this liquor should be shorter, otherwise the liquor will deteriorate, so the storage of liquor should also have a point in time, and it is not that the longer the time, the more mellow. High-quality liquor must have a proper shelf life.

Lu type liquor should be stored for at least 3 to 6 months, more than one year, Fen type liquor should be stored for about one year, and Mao type liquor is required to be stored for more than three years. The alcohol content is generally below 40 degrees, and it is considered a low-alcohol wine.

1. Liquor has no shelf life, 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.

2. Sauce-flavored liquor can be stored in the cellar of a professional manufacturer, and can be stored for a long time under certain humidity, temperature, soil, and 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.

3. The longer the aging and storage, the more conducive to the conclusion 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.

1. Generally speaking, liquor has no shelf life, and the storage conditions are different, and the longer the liquor, the more changes will be made. However, the shelf life of domestic liquor is 10 years. The relevant national standards stipulate that beverage wines with a liquor content greater than or equal to 10% vol can be exempted from labeling the shelf life.

However, it is meaningless to put the finished liquor for a long time, generally 3-5 years can be, too long, the trace components in it have changed, especially the fragrant liquor, the index is reduced, the taste changes, and it is not delicious.

2. 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.
