The red grape variety originates from Spain. Synonyms are Castañal, Mourisco and Rabo de Cordeiro. According to DNA analyses carried out in 2009, there is a parent-offspring relationship with the variety Amaral (Caíño Bravo). Until the beginning of the 20th century, it was widespread and very popular. The vine, which is almost extinct today, is cultivated in very small quantities on the Spanish-Portuguese border on the Spanish side of the river Miño. In 2016, three hectares of vines were reported (Kym Anderson statistics).
