The red grape variety originates from Portugal. Synonyms are Azedo, Bogalhal, Bogalhal, Borraco, Espadeiro Redondo, Olho de Sapo, Tinta Femia (Portugal); Caíño Gordo, Caíño Tinto (Spain). It was already described in 1790 by Botelho de Lacerda Lobo (1753-1822). Despite seemingly suggestive synonyms or morphological similarities, it should not be confused with the Amaral variety. The late-maturing, high-yielding vine with thick-skinned berries is susceptible to powdery mildew and especially botrytis, but is well suited to poor, dry soils. It produces ruby-coloured red wines with high acidity and alcohol content. In Portugal, the variety is mainly cultivated in the Douro, Beiras and Rios do Minho or Vinho Verde areas and occupies 163 hectares of vineyards. In Spain, it is cultivated in the Galicia region in the Rías Baixas and Ribeiro areas and occupies 350 hectares. In 2016, a total of 512 hectares of vineyards were designated (Kym Anderson).
