After opening the bottle, if there is an obvious vinegar, soy sauce or musty smell, no fruity aroma, a dull and dull color, and a large amount of sediment, it indicates that it has lost its drinking value; conversely, if the storage conditions are good, , the wine is not over-oxidized and can still be drank.

It should be pointed out that if the wine has been opened and not consumed at one time, the remaining wine must be sealed and placed horizontally in the refrigerator. It is best to drink it within a week. Because the oxygen entering after the bottle is opened will quickly oxidize the wine, and microorganisms in the air will also cause the remaining wine to deteriorate. To ensure safety, it is best not to continue drinking wine that has not been finished for a long time after it has been opened.

The shelf life of wine

For most low-priced wines on the market, the best drinking period is generally within 1 to 2 years. This type of wine is often characterized by a simple aroma composition, dominated by fresh berry aromas and floral aromas, simple oak barrel aging (or possibly no oak barrel aging), and medium alcohol, tannin intensity, and acidity. This kind of wine tastes good and is balanced and harmonious, but at the same time it lacks characteristics and has almost no preservation value. Consumers should drink it as soon as possible.

For a small number of medium-priced wines, the best drinking period may be three to five years later, or within 10 years. This type of wine usually has high alcohol content, acidity or tannin intensity, very rich fruit aroma, can withstand the test of time, and has certain preservation value.

For only a very small amount of high-quality vintage wines from famous wineries, the best drinking period may be more than 10 years or even longer, which requires winemakers to have deep experience and strong prediction ability.
