The red grape variety probably comes from Hungary. Synonyms are Kékmedoc, Médoc Noir and Menoire. For a long time it was considered a fact that the well-known Hungarian grape breeder János Mathiász (1838-1921) imported it from France to Hungary. An apparent confirmation was that Pierre Galet (1921-2019) equated it with the French variety Mornen Noir. According to DNA analyses carried out in 2013, it is a cross between Chasselas x Muscat d'Eisenstadt(Ingram's Muscat). However, this is based on only 20 DNA markers (see molecular genetics). Menoir was a crossing partner of the new breeding Gárdonyi Géza.
The variety was called Kékmedoc or Médoc Noir (also synonymous with Cot and Merlot) in Hungary. Due to protests from France, in 2004 the name was changed to the present name, which is a shortened form of the old one.

The variety is mainly cultivated in the Eger area. In 2010, 65 hectares of vineyards were designated in Hungary (Kym Anderson.
