The longer wine is stored in a wine kiln or oak barrel, the better. But the storage conditions after leaving the factory are different from those in wine kilns or oak barrels. Actually, there is a retention period. The shelf life of beer is 3 months. After opening the bottle, you must drink it on the same day. Red wine and wine have a long shelf life, and some dry red wines can be preserved for about 10 years; For liquor, it depends on the alcohol content, and the long-term preservation of liquor with a temperature above 40 degrees produced by manufacturers and brand manufacturers is not a big problem. If it is white wine produced by a small winery, some of it is mixed with spices, flavors and alcohol, so it can't be drunk by itself, let alone the shelf life. For the saying that "the older the wine, the more fragrant it is", it refers to the wine brewed and stored in a sealed barrel, and the bottled wine may become weak after a long time.
