Theoretically, wine has no shelf life, only a suitable drinking period. 3-5 years, if the wine is well preserved, it can still be drunk, but the flavor of the wine has declined and the taste is not good.

Regarding the shelf life of wine, in fact, in foreign countries, wine generally has no shelf life, only the best drinking period. For example, dry red and white wine is the best drinking period within five or six years after leaving the factory. In China, the relevant laws stipulate that the shelf life must be indicated on the label, so the saying of the shelf life of wine is a characteristic of our country. It is generally believed that expired wine will be turbid and precipitate, and the taste will be reduced, but it can still be drunk, but the taste is not good, which may be bad for people's health. If a bottle of wine that has passed the shelf life smells bad or as light as "swill" and has no characteristics of wine at all, there is no need to take risks to drink it; If the skeleton is loose, the aroma is gone and the taste is sour, you can drink it.

Like people, wine will go through various stages, such as youth, development, maturity, peak and decline. After aging, the excellent quality of wine will continue to be released for a period of time, which is the best drinking period of wine. All wines will reach the peak of quality in a certain period of time, and then slowly enter the decline period of quality.

90% of the wines on the market are suitable for drinking within 1 to 2 years. Only about 4% of high-quality wines have the aging potential of 5 to 10 years, and only the remaining 1% of top wines have the aging potential of more than 10 years. Therefore, most wines should be drunk within 10 years.
