The white grape variety (also Antonio Vaz) comes from Portugal. According to DNA analyses carried out in 2013, it is the result of a presumably natural cross between Cayetana Blanca x João Domingos. However, this is based on only 20 DNA markers (see molecular genetics). The medium ripening vine is generally well resistant to vine diseases and drought. It produces fresh white wines with a balanced alcohol-acid content and aromas of tropical fruits. The variety is mainly used as a blend in the Alentejo, Extremadura and Península de Setúbal areas. The area under cultivation in 2010 was 1,252 hectares, with a strong upward trend (ten years earlier it was 376 hectares).
