1. Red wine generally does not have a shelf life. The so-called "shelf life" is the "drinkable period".

The so-called "shelf life" is the period during which the quality of an item can be guaranteed. So, does wine have a “shelf life”? Yan Xiao, general manager of Bao Manlou of Yutang Mansion and the first ISG international sommelier in western Guangdong, said that the shelf life of wine in my country is generally ten years, while in foreign countries, wine generally has no shelf life. Because it is meaningless to discuss the shelf life of wine. People who love red wine are more concerned about whether a wine has the ability to age and when it will reach its best drinking period.

2. Red wine generally takes 10 to 20 years to reach maturity, which is the best state for drinking.

Wine is alive, from the formation of soil and climate to the planting, germination, flowering, fruiting and maturation of fruit trees, this is one of the life processes; and through brewing, fermentation, cultivation and maturation, It is another life process; the most important thing is that after bottling, through the oxidation of time, wine body and air, it will go through a parabolic life process of rawness, growth, maturity, old age and even death. Some wines take ten to twenty years to reach maturity, which is their best drinking period.

3. The so-called "deterioration" may mean that the wine is already in decline. More often, it is due to improper storage that causes the wine to become rough or become sour, bitter and smelly.

The so-called "deterioration" may mean that the wine is already in a period of decline. More often, it is due to improper storage that causes the wine to be rough or become sour, bitter and smelly. Therefore, it cannot be said that the quality has not improved during the shelf life. The problem is, if the shelf life has passed, there will be quality issues and you can’t drink it. In fact, no matter whether it is within the shelf life or outside the shelf life, if it has a bad smell or is as light as "water" and has completely lost the characteristics of red wine, there is no need to risk drinking it; if the skeleton is just loose, the aroma is gone, and the taste becomes worse. If it is sour, you can drink it, but it also loses the meaning of tasting wine.

4. Wine that has passed its shelf life can still be drunk.

In fact, wine that has passed its shelf life can still be drunk. Foreign wine labels do not indicate the shelf life, and there is no concept of shelf life. According to the understanding of Chinese people, wine within the shelf life should be clear, not turbid, not sedimentary, and should have the best taste. Wine that has exceeded its shelf life may appear cloudy and precipitate, and its taste quality may deteriorate, but it can still be drank. Red wine that has been aged for many years, such as dry red wine made from Cabernet Sauvignon and Cabernet Franc grapes, has been stored in new oak barrels for two years. It tastes very hard, bitter and astringent, and must be bottled for about 10 years or more. Only after storage can the taste become soft.

Suggested storage locations: under the bed, garage, closet, cellar, etc.

5. Precautions for wine storage.

Storage precautions: Appropriate temperature is required, the theoretical temperature is about 12 degrees, 7-18 degrees is acceptable; it is required to be protected from light, because ultraviolet rays will make the wine ripen prematurely and avoid vibration; place it horizontally and keep the cork moist.

Prevent air from entering and oxidizing red wine; avoid being too humid to prevent bacterial growth.
