The red grape variety (also Kaladok) is a new variety between Grenache Noir (Garnacha Tinta) x Cot, which was confirmed by DNA analyses carried out in 2013. The crossing was carried out in 1958 by the Frenchman Paul Truel (1924-2014) on behalf of the INRA at the Domaine de Vassal (branch of the University of Montpellier). The medium to late ripening vine is resistant to trickle (the primary breeding objective) and botrytis, as well as less susceptible to powdery mildew. It produces colourful red wines rich in tannin and alcohol, but is also used for the production of rosé wines. The variety is widespread in southern France and occupies a total of 3,062 hectares here. In Portugal, it is mainly planted in the Lisboa-Estremadura area on 2,180 hectares. There are also other smaller stands in Argentina (15 ha), Brazil (0.3 ha), Spain, Lebanon, Morocco and Switzerland (0.2 ha). In 2016, a total of 5,258 hectares of vineyard area were reported with an upward trend. This puts the variety in 111th place in the worldwide grape variety ranking (statistics Kym Anderson).
