An unopened bottle of white wine can last over three years past its printed date. Factors that determine the shelf life of a wine include its vintage, its label, how it was prepared and how it is stored.
Certain fine wines can last for up to 100 years when stored in a wine cellar, but most wines are intended for consumption soon after purchase. Methods to enhance the shelf life of a wine include storing it in a cool, dark area and placing it on its side to keep the cork airtight. Wine shouldn't be refrigerated until one to two days before consumption.
