The white grape variety comes from Portugal. Synonyms are Cedres, Olho de Pargo and Uva das Eiras. The parentage (parenthood) is unknown. The high-yielding vine is susceptible to botrytis. It is cultivated in the province of Minho, which is located in the far northwest, and on Porto Santo (part of the archipelago of Madeira). In 2010, the area under vine was 33 hectares, with a strong upward trend (Kym Anderson).
