High Quality Content by WIKIPEDIA articles! Greco is an Italian wine grape that may be of Greek origin. The name relates to both white (Greco bianco) and black (Greco nero) wine grape varieties. While there is more land area dedicated to Greco nero, the Greco bianco is the grape most commonly referred to by the shorthand "Greco". In the Campania region it is used to produce the Denominazione di Origine Controllata e Garantita (DOCG) wine Greco di Tufo. In Calabria, it is used to make the Denominazione di Origine Controllata (DOC) wine Greco di Bianco. The name "Greco" is sometimes used as a synonym for several varieties of supposed Greek origins-most notably Trebbiano.
