The white grape variety (also Geisenheim 22-74) is a new variety between Müller-Thurgau x Chasselas Tokay(Chasselas). According to DNA analyses carried out in 2012, the crossing of two Riesling clones indicated in the breeding list turned out to be wrong. The crossing was carried out in 1939 by Dr. Heinrich Birk (1898-1973) at the Geisenheim Research Institute (Rheingau), plant variety protection was granted in 1984. The name was given after the Arnsburg monastery near Gießen because the Cistercian order had rendered great services to viticulture in the Rheingau. It was a crossing partner in the new breeding of Saphira. The early-ripening, high-yielding vine is resistant to botrytis. It produces fruity white wines which are very suitable for sparkling wine. There are areas under cultivation in Germany (1 ha), on Madeira-Portugal (28 ha) and in New Zealand (2 ha). In 2010, a total of 31 hectares of vineyards were designated (Kym Anderson).
