WineFrog explains Scuppernong
The name of the scuppernong comes from the Scuppernong River in North Carolina located along the coastal plain. They were first mentioned as "white grape[s]" by Giovanni de Verrazzano, a Florentine explorer, while he was in the Cape Fear River Valley in 1524. He was writing about the wild vines growing in the region.
It was later cultivated in North Carolina for commercial production by Isaac Alexander who found the grapes while hunting along a stream that fed into Scuppernong Lake in 1755.
