Nebbiolo is a native black grape variety from Piedmont (Italy), considered valuable and suitable for high-quality wines for aging (DOC and DOCG). It is grown mainly in the hills of Langhe-Roero, then in some areas of Monferrato, Canavese, Asti and, to a lesser extent, Vercellese-Novarese (with the name of Spanna). Its partial cultivation is also authorized in some neighboring regions of Piedmont, such as Lombardy (in Valtellina, with the name of Chiavennasca) and in the Province of Varese (IGT Ronchi Varesini), in Valle d'Aosta (with the name of Picotener, Picotendre or Picotendro), and some areas of Sardinia (Luras).
