The white grape variety (also Geisenheim 17-52) is a new variety between Müller-Thurgau x Weißer Gutedel(Chasselas. According to DNA analyses published in 2012, the paternity of Chasselas Napoleon(Bicane), as stated in the breeding list, was found to be incorrect. The crossing was made in 1928 by Heinrich Birk (1898-1973) at the Geisenheim Research Institute (Rheingau). The late ripening, somewhat yield-insecure vine is well suited for cool climatic conditions. It produces rather neutral tasting white wines with a subtle grape aroma. However, the variety has not finally established itself in Germany. In England, two hectares of vineyard area were designated in 2010 (statistics Kym Anderson).
