The word vintage comes to us from the French and ultimately from the Latin vinum, meaning wine. Per the OED, originally (15th century), vintage just meant the grape harvest and by the 16th century was applied to the process of wine making (gathering, pressing, fermenting, etc.) The OED finds the first use of vintage as particularly good wine in 1604, and by 1746 it was applied to wine from a particular and particularly good harvest.
Vintage became an attributive noun, modifying nouns like day, dinner, festival, and home (the last patterned after harvest home, a festival to commemorate the end of the harvest season). The OED finds the first attributive sense in 1857, and notes that in 1888 the Encyclopedia Brittanica uses vintage class to denote particularly fine wine.
In 1939, the OED finds the first attribution of the jump from the best season of a wine to the best (or the best example) of a person's activity or character:
So this was a journey of centuries from a noun for wine and then for good wine, to a modifier about wine and then to a modifier for the best wine, and finally to a modifier of people, give the best example of their behavior or character.
