The white grape variety originates from Portugal. Synonyms are Camarate, Fernam Pires, Fernan Piriz, Fernão Pirão, Fernão Pires de Beco, Gaeiro, Gaieiro, Maria Gomes (second main name), Molinha, Molinho, Torrontés. It must not be confused with the varieties Bical (Fernão Pires Galego), Camarate, Fernão Pires de Colares (no longer cultivated) or Trebbiano Toscano, despite seemingly suggestive synonyms or morphological similarities. There is also a color mutation with pink berries called Fernão Pires Rosado. Fernão Pires is a common Portuguese surname. This suggests that some important but unknown personality was to be honored. The exact origin is probably Bairrada, where there are several varieties of this vine. The variety was a crossing partner in the new varieties Alvarinho Silvestre, Campanario, Casalze, Castelo Branco, Fepiro, Generosa, Marquinhas, Rio Grande and Seara Nova.
