The white grape variety is a new breed between Bicane x Chasselas, which was only discovered by DNA analyses carried out in 2009. In the breeding list it was listed as an open flowered seedling of Chasselas. Synonyms are Admirable, Admirable de Kurtile, Blanc de Courtiller, Chasselas de Courtiller, Csiri Szölö, Oseri and Roux de Courtiller. The crossing was made in France in the middle of the 19th century by Auguste Courtiller (1795-1875). It is used as a wine press and table grape. In some sources the variety is wrongly called the father variety of Müller-Thurgau (see under Madeleine Royale). It is cultivated in southern France(Rhône Valley). In 2010, 28 hectares of vineyards were designated (Kym Anderson).
