Helfensteiner is a dark-skinned German wine grape crossing of the species Vitis vinifera, that was created in 1931 with the crossing of Frühburgunder (Pinot Précoce noir) and Trollinger (Schiava Grossa). It was created by August Herold at the grape breeding institute in Weinsberg in the Württemberg region.
A relatively small amount of Helfensteiner is cultivated in Württemberg, 19 hectares (47 acres) in 2008 (and less than 1 ha in the rest of Germany combined). It produces red wines of a fruity character, and rosé wines. The reason for the variety's limited popularity with growers is its very variable yield, which is due to its susceptibility to flowering problems.
Helfensteiner is also known under its breeding code Weinsberg S 5332 and the synonyms Blauer Weinsberger and Helfensteyner.
