hang time
The time from veraison until the grapes are harvested. The longer the hang time the greater the fruit’s depth and complexity—perfectly ripe grapes produce superior, long-aging wines. On the other hand, if the hang time is too long, the grapes will become overripe, which will affect both flavor and aroma of the finished wine.
