A variety of French origin, historically associated with the Languedoc region. It is a grey mutation of the Rivairenc (Aspiran) variety. It belongs to late-maturing varieties, with the berry ripening period occurring approximately 4.5 weeks after the Chasselas variety.
Bunches and berries are large, and the skin color at maturity is grey. In terms of morphological traits and disease resistance, the variety is similar to the base Rivairenc variety. The wines produced are characterized as light, neutral, with a relatively low sugar accumulation potential.
The variety is rare; a certified clone exists under number 1408. Specific agrotechnical data in open publications are practically non-existent.
