The red grape variety originates from Algeria. Synonyms are Cherraga, Cot Cheraga, Cot Chernagua, Gros Mourvèdre de Cheragas and Mourvèdre d'Afrique. According to DNA analyses carried out in 2015, it comes from a presumably natural cross between Hebén x Monastrell. However, this is based on only 20 DNA markers (see molecular genetics). It should not be confused with the Valdiguié variety (Cot de Cheragas, Mourvèdre d'Afrique) due to synonyms or morphological similarities. No stocks were reported in 2016 (Kym Anderson statistics).
