The white grape variety comes from Italy. The name is derived from the Ligurian dialect word pigà or pigau and refers to the spots on the berries. It is also erroneously called Rossese Bianco, but should not be confused with this variety. Pigato is referred to in the M.I.P.A.A.F. catalogue of grape varieties as an independent variety, but also as a variety(mutation) or, as in Wine Grapes and in the VIVC catalogue, as identical to the variety Vermentino. In the DOC regulations of Liguria both Vermentino and Pigato are mentioned. In 2010, however, no stock was reported under the name Pigato (Kym Anderson).
