Variety of grape

Norton is grown in the Midwestern United States, the Mid Atlantic States, and northeastern Georgia. DNA data are consistent with 'Norton' being a hybrid with ancestry including V. aestivalis and V. vinifera. Norton was first cultivated in Richmond, Virginia, and is the official grape of the State of Missouri, and is considered the cornerstone of the Missouri wine industry. Daniel Norton first purveyed the Norton cultivar during the early 19th century from his vineyards in Virginia, USA.

The Norton cultivar was introduced by Daniel Norborne Norton of Richmond, Virginia, who selected it from among what he believed were seedlings of a long forgotten grape variety called Bland, though there is some doubt as to whether it was the actual source of the seed which yielded Norton. The male parent, presumably, was a wild vine of Vitis aestivalis. Another cultivar, called Cynthiana, closely resembles Norton, but has traditionally been considered a separate variety. Genetic studies, however, have shown the two to be indistinguishable. This grape became available commercially in 1830 and very soon after that came to dominate wine production in the eastern and midwestern states like Missouri and Ohio in the United States. Anthocyanins are the largest group of water soluble pigments in the plant kingdom and belong to the family of compounds known as polyphenols. Major sources of anthocyanins are blueberries, cherries, raspberries, strawberries, blackcurrants, purple grapes, and red wine. Anthocyanins are under basic research to understand if they have any biological role in humans.
