"Alexander"@en . . "Alexander (also known as Tasker's Grape) is a spontaneous cross of vines from which the first commercial wines in America were made. It was discovered in 1740 in the neighborhood of Springgettsbury, Philadelphia, in a vineyard where James Alexander (d. 1778), Thomas Penn's gardener, had originally planted cuttings of Vitis vinifera in 1683."@en . .
