The white grape variety is a new breed between Couderc 603(Bourrisquou x Rupestris) x Pedro Ximénez. Synonyms are 299-35, Couderc 19 and Couderc 299-35, and genes from Vitis rupestris and Vitis vinifera are included. The hybrid was crossed in 1894 by the breeder Georges Couderc (1850-1928) in France. The variety was a crossing partner for the new breeds L'Acadie Blanc and Valvin Muscat. However, the variety has no significance in cultivation; no stocks were reported in 2010 (Kym Anderson).
