The white grape variety originates from the border region Vinho Verde in Portugal and Galicia in Spain. SSynonyms are Alvarinho, Caino Branco, Cainho de Moreira, Caíño Branco and Caíño de Moreira. The variety was first mentioned in 1772. DNA analyses carried out in 2011 showed that the variety originated from a (most likely natural) cross between Caíño Bravo (Amaral) x Albariño (Alvarinho). This is why there has often been confusion between these three varieties in the past. The late-ripening vine is susceptible to powdery and downy mildew. It produces acidic, alcohol-rich white wines with a mineral tone, which are mostly used in blends with the Albariño variety. In Galicia, the vine is permitted in the DO areas of Monterrei and Rías Baixas and occupies 72 hectares. In Portugal, it is cultivated on 5 hectares. In 2016, a total of 77 hectares of vines were designated (Kym Anderson).
