The shelf life of red wine is an inaccurate concept. It’s not that if it’s within the shelf life, the quality is fine; if it’s past the shelf life, there’s a quality problem and you can’t drink it. In fact, you can still drink red wine after its expiration date. Foreign wine labels do not indicate the shelf life, and there is no concept of shelf life. \x0d\According to the understanding of Chinese people, red wine within the shelf life should be clear, not turbid, not precipitated, and should have the best taste. Red wine that has exceeded its shelf life may appear cloudy and precipitate, and its taste and quality may deteriorate, but it can still be drank. \x0d\Red wine that has been aged for many years, such as dry red wine made from Cabernet Sauvignon and Cabernet Franc grapes, has been stored in new oak barrels for two years. It tastes very hard, bitter and astringent, and must be aged for about ten years or more. Only after the above bottle storage can the taste become soft, plump, mellow and rich, becoming a truly aged wine. A.O.C-level red wines produced in France's Burgundy and Bordeaux are priceless, and some are people's collections. Cloudiness and sedimentation are normal in such highly valued red wines. When drinking this kind of red wine, you need to pour the bottle to separate the sediment at the bottom of the bottle, which can give people great value for enjoyment. \x0d\Generally, the shelf life of red wine is calculated from the time when the fermented original wine is filled. It usually needs to be fermented in oak barrels for about half a year and then filled into bottles. The shelf life should be calculated from this time. Red wine is just like a living body. The red wine that has just been filled is relatively young and is generally light red in color. As time goes by, the color gradually changes to dark red, which is a mature red wine! As for how the shelf life of red wine is determined, according to French red wine standards, experts generally determine which level the red wine of this year belongs to based on the climate and various conditions of the year, and then determine its shelf life. Wine from a good vintage can still be stored for a long time, and it tastes very good! \x0d\For the red wine we often drink, you can try it and taste it. If the taste does not change and the taste is still good, you can drink it. If it tastes bad or smells bad, don’t drink it. After opening the red wine, it is best to drink it all at once or within a short period of time.
