The white grape variety comes from Italy. It must not be confused with the Fiano variety, for which the synonym Santa Sofia is confusingly used and which was long considered identical. This was refuted by DNA analyses carried out in 2005 and a close relationship was found with the local variety Rosso Antico, which is no longer cultivated. Until the phylloxera catastrophe, the variety was widely used as a wine press and table grape in the Campania region in the province of Salerno. Today there are only a few old vineyards south of Salerno. The white wine made from it is blended with the varieties Fiano and Trebbiano Toscano in the Campania DOC white wine Cilento. In 2010, however, no stocks were reported (Kym Anderson).
