The white grape variety (also Geisenheim 7116-26) is a new breeding between Geisenheim 323-58 (Seibel 7053 = Chancellor x Riesling) x Ehrenfelser. It contains genes from Vitis labrusca, Vitis lincecumii, Vitis rupestris and Vitis vinifera. The crossing of the hybrids was carried out in 1971 at the Geisenheim Research Institute (Rheingau) by Professor Dr. Helmut Becker (1927-1990). The plant variety protection was granted in 1997. The medium to late-maturing, frost-hardy vine is resistant to both types of mildew and only slightly susceptible to botrytis. It is therefore considered a PIWI variety. However, it is susceptible to red distillers. It produces fragrant, fruity white wines similar to Riesling. In Germany, the variety occupied three hectares of vineyards in 2009.
