The white grape variety is a new breed between Bicane x Chasselas. The parentage was last revealed by DNA analyses carried out in 2013, as 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). The early-maturing vine is susceptible to coulure (Millerandage). It is used as a wine grape and table grape. The variety was mistakenly regarded as the father variety of Müller-Thurgau (which is Madeleine Royale). It is cultivated in the south of France (Rhône Valley). 27 hectares of vineyards were designated in 2016 (Kym Anderson statistics).
