The red grape variety (also known as Blauer Weinsberger, Helfensteyner) is a new variety between Pinot PrécoceNoir x Schiava Grossa, which was confirmed by DNA analyses published in 2012. The cross was made in 1931 by August Herold (1902-1973) at the Weinsberg State Teaching and Research Institute in Württemberg. It was named after the former castle near Geislingen. The plant variety protection was granted in 1960. The variety was a cross-breeding partner in the two new varieties Dornfelder and Hegel. The medium to late ripening vine is resistant to powdery and downy mildew as well as botrytis, but susceptible to trickling and therefore uncertain in yield. In 2018, the variety occupied 12 hectares of vineyards in Germany with a constantly falling trend (D-STATIS).
