The red grape variety comes from France; the name means "red" after a local dialect. Synonyms are Arhuya, Aroyat, Arrouyat, Arroya, Arruya, Dourec Noir, Dourech Noir, Dourecq Noir, Eremachaoua, Eremachoua, Erematxahua and Rouja. Nothing is known about the parentage (parenthood) and a possible genetic relationship to the white variety Ondenc (with synonym Dourec). It should not be confused with the Cabernet Franc, Camaraou Noir, Fer, Manseng Noir or Petit Courbu varieties, despite synonyms or morphological similarities that seem to indicate this. The late maturing vine is susceptible to downy mildew, black rot and botrytis. It produces a light red, acidic simple red wine with a bitter hue. The endangered variety is cultivated in small quantities in the Jurançon area in south-west France. In 2016, only 0.1 hectares of vineyard area were designated (statistics Kym Anderson).
