The red grape variety comes from Portugal. Synonyms are Ramisco de Colares, Ramisco nos Açores and Ramisco Tinto. According to DNA analyses carried out in 2015, it is a parent of the Concieira variety. However, this is based on only 21 DNA marhers (see molecular genetics). There is also a close genetic relationship with the Sercial and Trincadeira Preta varieties. The late ripening vine has particularly thick berry skins. It produces extremely dark-coloured, acid and tannin-rich red wines with earthy aromas of mushrooms and cedar wood, and storage potential. The variety is cultivated in the DOC area Colares on the Atlantic coast. A special feature is that the vineyards were spared from phylloxera due to the deep sandy soil there and therefore the variety is cultivated true to its roots. The area under cultivation in 2010 was 23 hectares (Kym Anderson).
