The red grape variety originates from Portugal or from France. Synonyms are Alfrocheiro Preto, Alfurcheiro, Bastardo, Bastardo Negro, Tinta Bastardinha, Tinta Fina, Tinta Francesa de Viseu (Portugal); Albarín Frances, Albarín Negro, Albarín Tinto, Baboso Negro, Bruñal, Caíño Gordo, Negrona (Spain). This is probably a very old variety, although it was first mentioned relatively late, in 1971. According to a hypothesis, it was imported from France, which could be indicated by the synonym Tinta Francesa de Viseu. The parentage is unknown. It is not a colour mutation of the two white varieties Albarín Blanco or Alfrocheiro Branco (Trebbiano Toscano) or vice versa. According to DNA analyses carried out in 2018, it comes from a presumably natural cross between Traminer x unknown partner.
