The red grape variety is a new variety between Grenache Noir (Garnacha Tinta) x Jurançon Noir. Synonyms are Chenason, Chenançon, Pineau Gros, Shenanson and Vaalblaar Stein. The cross was made in France in 1958 by the ampelographer Paul Truel (1924-2014) on behalf of INRA at the Domaine de Vassal. Incidentally, the same parents also gave rise to the Ganson variety. This medium-maturing, high-yielding vine produces dark-coloured, fruity red wines with soft tannins. It is cultivated in southern France, mainly in the départements of Aude, Gard, Hérault and Vaucluse, on a total of 451 hectares. There are small areas of cultivation in the Spanish Penedès as well as in Australia in the Riverina area with 1.5 hectares. In 2016, 452 hectares of vines were reported (Kym Anderson statistics).
