The red grape variety originates from Portugal. Synonyms are Bastardão, Bastardo, Espagnin, Monvedro Dão, Monvredo do Algarve and Preto João Mendes. The parentage (parentage) is unknown. It should not be confused with the varieties Monvredo, Parraleta (Espagnin, Monvedro) or Trousseau Noir (Bastardo), despite seemingly indicating synonyms or morphological similarities. Its distinctiveness was confirmed by DNA analyses carried out in 2010. The variety is grown in the Beiras area. In 2016, four hectares of vines were designated (Kym Anderson).
