Dornfelder is a dark-skinned variety of grape of German origin used for red wine. It was created by August Herold (1902-1973) at the grape breeding institute in Weinsberg in the Württemberg region in 1955. Herold crossed the grape varieties Helfensteiner and Heroldrebe, the latter which bears his name, to create Dornfelder. Helfensteiner (Frühburgunder × Trollinger) and Heroldrebe (Blauer Portugieser × Lemberger) were both crosses created some decades earlier by Herold.
