The red grape variety (also Weinsberg S 341) is a new cross between Helfensteiner x Heroldrebe (which was confirmed by DNA analyses published in 2012). The cross was made in 1955 by August Herold (1902-1973) at the Lehr- und Versuchsanstalt Weinsberg in Württemberg (Germany). Plant variety protection was granted in 1979. The name goes back to Immanuel A. L. Dornfeld (1796-1869), after whose initiative the viticultural school in Weinsberg was founded. The same parents also created the Hegel variety. Dornfelder was a crossing partner of the new varieties Acolon, Cabernet Dorio, Cabernet Dorsa and Monarch. Dornfelder is one of the most successful new German varieties.
