The white grape variety originates from Italy. Synonyms are Grechetto, Grechetto Bianco, Grechetto Spoletino, Greco, Greco Spoletino, Montanarino Bianco, Montanaro, Pistillo, Pizzinculko, Pocinculo, Pulce, Pulcinculo Bianco and Strozzavolpe. The "Greco" could possibly indicate a Greek origin. Despite synonyms or morphological similarities that seem to indicate this, it should not be confused with the varieties Maceratino or Pignoletto (with synonym Grechetto di Todi). However, according to DNA analyses carried out in 2004, there is a parent-progeny relationship between Grechetto di Orvieto and Pignoletto, which is why they used to be considered two clones of the same variety and were often named only "Grechetto" in DOC determinations, which naturally leads to some confusion and confusion with other Grechetto varieties. There is also the red-berried variety Grechetto Rosso (Greghetto) of uncertain parentage.
