A grape is the non-climacteric fruit, botanically a true berry, that grows on the perennial and deciduous woody vines of the genus Vitis.
Grapes can be eaten raw or used for making jam,juice, jelly, vinegar, drugs, wine, grape seed extracts, raisins, and grape seed oil.
Grapes are also used in some kinds of Confectionery. Grapes grow in clusters of 6 to 300, and can be crimson, black, dark blue, yellow, green
and pink. "White" grapes are actually green in color, and are evolutionarily derived from the purple grape. Mutations in two regulatory genes
of white grapes turn off production of anthocyanins which are responsible for the color of purple grapes. Anthocyanins and other pigment chemicals
of the larger family of polyphenols in purple grapes are responsible for the varying shades of purple in red wines.
The domestication of purple
grapes originated in what is now southern Turkey. Yeast, one of the earliest domesticated microorganisms, occurs naturally on the skins of
grapes, leading to the innovation of alcoholic drinks such as wine. Ancient Egyptian hieroglyphics record the cultivation of purple grapes,
and history attests to the ancient Greeks, Phoenicians and Romans growing purple grapes for both eating and wine production. Later, the growing
of grapes spread to Europe, North Africa, and eventually North America.
