The white grape variety comes from Switzerland or Hungary. Synonyms are Bordeaux Blanc, Bourgogne Blanc, Gamay Blanc, Gros Bourgignon and Gros Bourgogne. The Swiss-German name is derived from "Blanchier" (white). According to DNA analyses carried out in 2004, it is a direct descendant of the Hungarian variety Furmint; the second parent is unknown. In Switzerland, the variety is counted among the Old Growths grape variety group. The medium maturing vine is susceptible to Botrytis. It produces white wines with moderate acidity and light camilleton. It is cultivated in small quantities in the commune of Visperterminen in Valais and Vaud. However, no stocks were recorded in 2010 (statistics Kym Anderson).
