The white grape variety is a new cross between Raffiat de Moncade x Sauvignon Blanc. The crossing was carried out on behalf of INRA by the Basque Pierre Marcel Durquéty (1923-2016) with the support of the University of Montpellier. Incidentally, the same parents also gave rise to the Arriloba variety. The vine yields a fruity white wine reminiscent of Sauvignon Blanc. No stocks were reported in 2016 (Kym Anderson statistics).
For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.
