Nebbiolo is an autochthonous black-berry vine from Piedmont (Italy), considered valuable and suitable for high quality aging wines (D.O.C. and D.O.C.G.). The term seems to derive from "fog", but it is unclear whether to define the appearance of the berry, dark, but clouded (clouded) by abundant pruina, or if due to the very late ripening of the grapes, which often leads to harvest in the period of autumn mists. Nebbiolo has its first historical citations at the end of the thirteenth century, for its presence in various places, primarily in Piedmont, especially for the Asti and the Langhe: in 1431 it is mentioned in the statutes of La Morra together with Pignolo. Only since the nineteenth century Nebbiolo is frequently cited in the works of the most famous ampelographers.
