The white grape variety originates from Portugal. Synonyms are Cedres, Olho de Pargo and Uva das Eiras. The parentage is unknown. The high-yielding vine is susceptible to botrytis. It is cultivated in the province of Minho, which is located in the very northwest, as well as on Porto Santo (part of the Madeira archipelago). In 2016, an area of 33 hectares was reported under cultivation, with a strong upward trend (Kym Anderson statistics).

There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
