means Describing something from an earlier era valued for its quality, character, or charm — and, for wine, the year a particular harvest was gathered.

from From Old French vendange, meaning the grape harvest, which traces back to Latin vindemia — a blend of vinum (wine) and demere (to take away or gather). So at its root, 'vintage' is simply the act of picking grapes; only later did it stretch to mean the wine of a particular year, then any object distinguished by its age.
