Vitis vinifera

Vitis vinifera – the name of a grape family for the viticulture.
Only the European grape varieties are suitable for good wines.
There are about 6000 known grape varieties suited to make wine from.
It is not allowed to call liquor made from other grape varieties “wine”.
Also it isn’t allowed to use hybrids for wine: crosses between European and American grapes.
There are a few exemptions:
Vidal, a hybrid from the French Ugni blanc and the American Seibel grapes, used for Canadian Ice Wine.
Baco 22A, used for Argagnac and the only allowed hybrid grape in France.
