Complete definition
Grape harvest or vintage, in wine-making, is the process of picking grapes and creating the finished product.

In certain wines, it can denote quality, as in Port wine, where Port houses make and declare vintage Port in their best years. From this tradition, a common, though incorrect, usage applies the term to any wine that is perceived to be particularly old or of a particularly high quality.
