Question: how long is a corked bottle of red wine good for?
Answer: 3–5 days in a cool dark place with a cork The more tannin and acidity the red wine has, the longer it tends to last after opening. So, a light red with very little tannin, such as Pinot Noir, won't last open as long as a rich red like Petite Sirah. Some wines will even improve after the first day open.
