Dunkelfelder is a dark-skinned variety of grape used for red wine. It was created by Germanviticulturalist Gustav Adolf Froelich (1847-1912). He probably crossed Färbertraube (a teinturier) with Blauer Portugieser. The variety, initially called Froelich V 4-4, did not receive any attention for several decades until work was continued on it at Geisenheim grape breeding institute in the 1930s.
