Term (also wine grape) for those grapes from vines that are grown for the production of wine or spirits such as brandy(Armagnac, Cognac, Metaxa, etc.) and even vodka (together about 85% worldwide). Other groups include table grapes (edible grapes) and sultanas. There are about 8,000 to 10,000 different grape varieties worldwide, with the morphology(leaf shape as well as size, texture and colour of the grapes or berries) being characteristic of the respective variety. The vine develops the grape in the course of the annual vegetative cycle. As a rule, the grapes are harvested when they are as physiologically ripe as possible. For Prädikat wine types such as Spätlese, Beerenauslese, Trockenbeerenauslese or Eiswein, this takes place much later because a special grape condition is required for this. Especially in Austria and Germany, a certain sugar level of the grapes during the harvest is an important criterion for the later wine quality level (see must weight).
