Vitis vinifera
Vitis vinifera, the common grape vine, is a species of flowering plant, native to the Mediterranean region, Central Europe, and southwestern Asia, from Morocco and Portugal north to southern Germany and east to northern Iran. There are currently between 5,000 and 10,000 varieties of Vitis vinifera grapes though only a few are of commercial significance for wine and table grape production. The wild grape is often classified as Vitis vinifera sylvestris (in some classifications considered Vitis sylvestris), with Vitis vinifera vinifera restricted to cultivated forms. Domesticated vines have hermaphrodite flowers, but sylvestris is dioecious (male and female flowers on separate plants) and pollination is required for fruit to develop. Grapes can be eaten fresh or dried to produce raisins, sultanas, and currants. Grape leaves are used in the cuisine of many cultures. The fresh grapes can also be processed into juice that is fermented to make wine and vinegar. Cultivars of Vitis vinifera form the basis of the majority of wines produced around the world. All of the familiar wine varieties belong to Vitis vinifera, which is cultivated on every continent except for Antarctica, and in all the major wine regions of the world. Wild grapes were harvested by neolithic foragers and early farmers. For thousands of years, the fruit has been harvested for both medicinal and nutritional value; its history is intimately entwined with the history of wine. Changes in pip (seed) shape (narrower in domesticated forms) and distribution point to domestication occurring about 3500–3000 BC, in southwest Asia, South Caucasus (Georgia), or the Western Black Sea shore region (Bulgaria, Romania). The earliest evidence of domesticated grapes has been found at Gadachrili Gora, near the village of Imiri, Marneuli Municipality, in southeastern Georgia; carbon-dating points to the date of about 6000 BC. Grape pips dating back to the 5th–4th millennium BC were also found in Shulaveri; others dating back to the 4th millennium BC were also found in Khizanaant Gora, all in the country of Georgia.
