How long can wine be stored?
In general, red wines are aging wines and whites are drinking wines. Actual maturation times for red wines depend on the type of wine and its complexity, quality, and vintage. Tannins, which come from the grape stems and skins, are the backbone of the aging process. Tannins produce a sharp, bitter taste, which over time will precipitate out of the wine allowing the other characteristics of the wine to come forth. When stored properly, complex red wines can be stored for decades or even centuries because they usually have a higher tannin content.
