The red grape variety originates from France. Synonyms are Baccalan, Bacclan, Baclan, Baclans, Baitran, Becclan, Béclan du Jura, Beikian, Beitran, Durau, Dureau, Duret, Margillin Petit, Petit Baclan, Petit Béclan, Petit Dureau, Petit Margillin, Roussette Noir, Saunoir, Saut Noir, Sceau Noir, Seaut Noir and Süßschwarz. Despite seemingly suggestive synonyms or morphological similarities, it must not be confused with the varieties Durif, Peloursin (with synonym Gros Béclan) or Pinot Noir. The early-maturing, low-yielding vine is susceptible to downy mildew. It produces light-coloured, rather low-alcohol red wines. In a catalogue of grape varieties published in 1897 by the ampelographer Charles Rouget, about 500 hectares are still mentioned. Today, the variety is threatened with extinction and is only grown in tiny quantities in the Jura region. In 2016, 0.1 hectares of vines were identified (Kym Anderson statistics).
