The red grape variety comes from Portugal. Synonyms are Azedo, Bogalhal, Borraco, Espadeiro Redondo, Olho de Sapo, Tinta Femia(Portugal); Caíño Tinto(Spain). It was already described in 1790 by Botelho de Lacerda Lobo (1753-1822). Although it appears to have synonyms or morphological similarities, it should not be confused with the Amaral variety. This late-ripening, high-yielding vine with thick-skinned berries is susceptible to powdery mildew and especially to botrytis, but is well suited to barren, dry soils. It produces ruby red wines with high acidity and alcohol content. The variety is mainly grown in Portugal in the Douro, Beiras and Rios do Minho and Vinho Verde areas. In 2010, 160 hectares of vineyard area were designated with a strong downward trend (ten years earlier it was 2,035 hectares). In Spain, it is cultivated under the name Caíño Tinto in the Galician region, mainly in the Rías Baixas and Ribeiro areas. A total of 523 hectares were recorded here in 2010 (ten years previously there were 619 hectares).
