Nebbiolo is the native Piedmontese grape par excellence. According to some sources, the origin of its name is to be found in the word “nebbia” (fog), as the berries are coated in a wax-like substance called pruinescence; others link it to the time of the harvest, late October, when the vineyards are shrouded every day in the morning fog. Nebbiolo is the most refined italian black grape variety of all; it is also the Piedmontese grape that presents the most heterogeneous “population”, which is likely the result of more frequent mutations.
It takes the name of Spanna in the areas of Boca, Bramaterra, Fara, Ghemme, Lessona and Sizzano.
