She is not allowed to use the name-like new breed Alexander Winter be confused. It is a presumably natural cross between species of a wild Vitis labrusca x an unknown Vitis vinifera, The picture is from the botanist Johann S. Kerner (1755-1830) from his catalog of grape varieties used at that time in Germany.
The late ripening hybrid was built around the year 1740 on the shores of the Schuylkill River near the town of Springettsbury northwest of Philadelphia in what is now the US state Pennsylvania Discovered, selected, multiplied and cultivated by 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, which had been created in the 1680s for William Penn and probably from which one parent came from.
Initially, the species became known after the river as Schuylkill Muscadel and similar names. A few years before the American Revolution, it was taken in the 1760s by a Colonel Benjamin Tasker in culture and as Tasker's Grape on a large scale in today's US state Maryland grown. The name Clifton's Constantia, in turn, goes back to a William Clifton who claims to have found her in his garden in Southwark, Philadelphia. There would be two different origins, but due to the great similarity, it is believed that it is only one sport the "real" Alexander Grape acted.
The US viticulture pioneer Jean Jacques Dufour (1763-1827) planted it in 1799 Kentucky and named her Cape Grape because he falsely assumed she was from the Cape of Good Hope from South Africa. The third US President Thomas Jefferson (1743-1826), from 1809 referred her to his experiments on his estate Monticello in Virginia and designated the wine with the typical Foxton even as burgundy-like. The variety Alexander was in the consequence in the south of the USA widespread, but was then of the Catawba displaced and finally fell into oblivion. In August 2000, it was replanted and revived as part of a historic reproduction program at Jefferson Vineyards (Monticello, Virginia).
