Dunkelfelder
Dunkelfelder was created by German viticulturalist Gustav Adolf Froelich. The variety, initially called Froelich V 4-4, did not receive any attention for several decades until work was continued on it at the Geisenheim grape breeding institute in the 1930s. It was named Dunkelfelder (dunkel = dark) due to its unclear parentage and its dark color. In 2008, there were 352 (869 acres) of Dunkelfelder in Germany.
