It is not allowed with new breeding similar to the name Alexander Winter be confused. It is believed to be a natural cross between a wild species Vitis labrusca x an unknown Vitis vinifera, The picture is from the botanist Johann S. Kerner (1755-1830) from his catalog of the grape varieties used in Germany at that time.
The late ripening hybrid was built around 1740 on the banks of the Schuylkill River near the town of Springettsbury, northwest of Philadelphia in what is now the US state Pennsylvania discovered, selected, propagated and cultivated by a James Alexander. This man was the gardener of the Governor of Pennsylvania Thomas Penn (1702-1775), a son of the famous Quaker leader William Penn (1644-1718), after whom the US state is named. The site was close to a vineyard planted with European vines that had been created for William Penn in the 1680s and from which one of the parents probably came.
Initially, after the river, the variety became known as Schuylkill Muscadel and similar names. A few years before the American Revolution, it was cultivated by a Colonel Benjamin Tasker in the 1760s and a large-scale Tasker's Grape in what is now the US state Maryland grown. The name Clifton's Constantia comes from a William Clifton who claims to have found it in his garden in Southwark, Philadelphia. There would be two different origins, but due to the great similarity, it is assumed that it is only one sport the "real" Alexander Grape acted.
The US wine pioneer Jean Jacques Dufour (1763-1827) planted it in 1799 Kentucky and called it Cape Grape because he mistakenly assumed that it came from the Cape of Good Hope in South Africa. The third US President Thomas Jefferson (1743-1826), from 1809 it involved in his experiments on his Monticello estate in Virginia and labeled the wine with the typical Foxton even like burgundy. The variety Alexander was subsequently widespread in the south of the USA, but was then by the Catawba displaced and was finally forgotten. In August 2000, it was replanted in the course of a historical reproduction program in the Jefferson Vineyards (Monticello in Virginia) and thus revived.
