It depends on the situation

Wine is alive, and good wine has a process from young to mature, to peak, and then to decline during its aging process. It is not very accurate to use "shelf life" to describe red wine. Strictly speaking, it is the "drinking period". It is generally ideal to drink wine at its peak. Even in its decline period, the changes in wine are gradual and cannot be absolute. It is said that it is no longer drinkable, but the quality is not good or the taste is bad, so people naturally do not want to drink it anymore.

The older the wine, the better. Whether you can drink wine that has passed its shelf life depends on the specific situation, because some wines may not go bad after they have expired, but wine that has not expired may also go bad. Its quality is closely related to its preservation method. If it is stored properly, even if it has expired for several months, it can still be drunk if it tastes good. However, if it has expired for too long, it is not recommended to drink it.

Extended information:

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.
