Wild Euro-Asiatic grape wine distribution, between Mediterranean area and Persian Gulf

Vavilov N.I., discovered in Georgia, Armenia and Azerbaijan some of the possible areas of origin and spread of the grape. Such width area, than extends from the Black Sea to the Caspian , is dominated by the Caucasus mountain (natural barrier between Europe and Asia). Its geomorphology is dominated by large valleys with moderated climate, between the rivers Kura and Arakas, which seem to supply the environmental conditions sweet able for the cultivation of grape. Moreover there are many vegetable species (more than 6000) which cohabit with the three main families of wild and domestic vitis vinifera. The Vitis occidentalis is typical of central and western Europe, the Vitis orientalis of central Asia (Azerbaigian and Armenia) and the Vitis pontica of oriental Europe, southern Russia and Turkey.
