Extract of Grape seed  


Sources and Habitat


A grape is the non-climacteric fruit, botanically a true berry that grows on the perennial and deciduous woody vines of the genus Vitis.


Grape domestication 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 show the cultivation of grapes, and the ancient Greeks, Phoenicians and Romans also grew grapes for both eating and wine production. Later, the growing of grapes spread to Europe, North Africa, and eventually North America.
