According to researchers, red wine is very beneficial for the heart if taken in moderate amounts. However, a foul red wine can do you more harm than good. Red wine, if unopened, can last for as long as 150 years. However, a 50 year old red wine is considered to be the best. Once opened, it is necessary to keep the bottle red wine in the fridge to prevent it from going bad. If the cork is put back on after every time it is opened, refrigerated red wine can last up to a month.
Red wine is a rare alcoholic drink which is good for the heart when had in moderation. As in the case of all wines, the older the red wine is the better. However, once opened, red wine does not have a very long shelf life. Ideally, red wine lasts for only two to three days.
