Fiano is a white Italian wine grape variety that is grown primarily in the Campania region of southern Italy and on the island of Sicily. In Campania, this fairly strong flavored white wine grape is particularly noted around Avellino where the Denominazione di origine controllata e Garantita (DOCG) wine of Fiano di Avellino is produced. The grape has a long history in the Campanian region and is believed to have been the grape behind the ancient Roman wineApianum. Even today, the name Apianum is permitted to appear on wine labels of the DOCG wine Fiano di Avellino.
Outside of Italy, several Australian wine producers have begun to use the grape. Production seems to be increasing, although the number of vineyards growing it is still small. One place of production is in the McLaren Vale wine region of South Australia. More recently, some winemakers in Argentina are producing Fiano in the La Rioja district, north of Mendoza.
Beyond its strong flavors and intense aroma notes, the Fiano grapevine is noted viticulturally for the relatively low yields it produces.
