The white grape variety is a new cross between Bicane x Chasselas. The parentage was revealed by DNA analyses last carried out in 2013, because the variety was indicated in the breeding list as an open-pollinated seedling of Chasselas. Synonyms are Admirable, Admirabl de Kurtile, Blanc de Courtiller, Budaoersi, Chasselas de Courtiller, Courtiller Esodalatosa, Csiri Szölö, Futogyonegy, Oseri, Roux de Courtiller and Shasla Steklyannaya. The cross was made in France in the middle of the 19th century by Auguste Courtiller (1795-1875). It is used as wine grape and table grape. For some time, the variety was mistakenly considered the father variety of Müller-Thurgau (see Madeleine Royale). It is cultivated in southern France (Rhône Valley). In 2016, 27 hectares of vineyard area were designated (statistics Kym Anderson).
