The red grape variety comes from France. The name is derived from "col" (grape stalk) and "tor" (twisted) and refers to the strongly twisted stalk. Synonyms are Assadoule Bouvier, Binxeilla, Bouteillan, Canseron, Cayau, Colitor, Col Tor, Coulitor, Coy Tor, Dameron des Vosges, Foirard, Foirat, Fouiraire, Fouiral, Fouirassan, Garriga, Pécoui Touar, Pécoui Tovar, Picpoul de Fronton. Although it appears to have synonyms or morphological similarities, it must not be confused with the varieties Bouteillan Noir (Fouiral), Brachetto del Piemonte (Calitor), Braquet Noir, Jurançon Noir or Piquepoul Noir. Two colour mutations are Calitor Blanc and Calitor Gris. The variety was already mentioned in 1600 by the agronomist Olivier de Serres (1539-1619) in a list of grape varieties under the name Colitor. The late ripening vine is resistant to powdery mildew, but susceptible to downy mildew and botrytis. It produces light-coloured, low acid and alcohol red wines for blending. The variety was formerly widespread in France on the southern Rhône and in Provence. However, the besatand has shrunk considerably. In 2016, only 26 hectares of vineyards were planted (Kym Anderson).
