Grape

Grape, common name of an edible fruit in the buckthorn family, and of the vines that produce the fruit. The European grape has been used as food since prehistoric times. Grape seeds have been found in remains of lake dwellings of the Bronze Age in Switzerland and Italy and in tombs of ancient Egypt. Botanists believe that the Caspian Sea region was the original home of the European grape. Distribution of seeds by birds, wind, and water carried the plant westward to the Asian shores of the Mediterranean. Grape culture, practiced in Palestine during biblical times, was introduced in the Mediterranean region by seagoing Phoenicians. The ancient Greeks cultivated grapes, and use of the fruit was later adopted by Rome and its tributary territories.

Grapevines are stems that climb on walls and fences by means of specialized supporting organs, called tendrils. Palmately veined leaves arise alternately along the stem. In most varieties, tendrils arise opposite two of every three successive leaves. Flowers, usually greenish, are borne in clusters and have staminate and pistillate flowers sometimes occurring on separate plants. Fruit is borne on 2-year-old canes, which are removed after harvesting the grapes.

Scientific classification: Grapes belong to the family Vitaceae. The European grape is classified as Vitis vinifera, the northern fox grape as Vitis labrusca, the summer grape as Vitis aestivalis, the riverbank grape as Vitis riparia, and the muscadine grape as Vitis rotundifolia.
