The white grape variety comes from France. The name means "smoky" in the local dialect and refers to the colour of the flowers. The assumption that the variety Sauvignon Gris (a mutation of Sauvignon Blanc) is identical was disproved by DNA analyses carried out in 2007. There is a great morphological similarity with the variety Camaralet de Lasseube. However, the parentage (parenthood) is unknown. The early ripening vine is sensitive to spring frosts and powdery mildew, but resistant to botrytis. It produces white wines with storage potential. The variety is grown in small quantities in south-west France in the Jurançon and Madiran areas. However, no stocks were reported in 2010 (statistics Kym Anderson).
