There is no shelf life for wine, and wine only has the concept of suitable drinking period. The suitable drinking period is different for different wines. You bought one or two hundred yuan of red wine in the supermarket, and you'd better finish it in two or three years. White wine should also be finished at this time. If you can't finish it, it will exceed the drinking period, and the wine may not taste good. If it is a famous Bordeaux village with a bottle of several thousand yuan, such as Lafite and Latour, if the year is not very good, his drinking period is about ten years. If the year is particularly good, such as Mouton in 1945, he can still drink it in 245. Good burgundy wines have a longer drinking period, and it is no problem to keep them for decades, such as la tahe and Romannikondi, and it is no problem to keep them for decades for white wines such as Monhasche. Barolo in Italy is also no problem for 4 or 5 years. Sweet wine is also a wine with a long drinking period. If you buy Portuguese madeira wine, there will be no suitable drinking period, and it will be no problem to open it after hundreds of years.
