how long does red wine last after opening

Red wine typically lasts between 3 and 5 days after opening if it is stored properly. It is best to keep the opened bottle in a cool, dark place, preferably in the refrigerator with the cork or a wine stopper tightly sealed to minimize exposure to oxygen. Some full-bodied red wines with higher tannin levels, such as Cabernet Sauvignon, may last slightly longer, while lighter red wines like Pinot Noir may start to lose their character earlier, around 2 to 3 days. After this period, the wine's flavor, aroma, and appearance can deteriorate, often becoming sour or vinegary, which indicates it is no longer good to drink.
