In the northwest of Italy lies the Piemonte region, with Turin as the main city. Piemonte, literally 'land at the foot of the mountain', is surrounded in the north near the Aosta valley by Alpine giants, which offer natural protection. Although some viticulture also occurs here, the vine south of the Po River in particular performs optimally. In this part of Piedmont, microclimates can easily form and, together with the unique soil, form an ideal combination for making top wines. One of the leading wineries in Piedmont is Ceretto. Ceretto is one of Barolo's most famous names. Ceretto built its wineries in 1982 in the village of Castiglione Falletto with vineyards in a number of famous crus, such as Brunate and Cannubi. Ceretto was one of the forerunners in making vineyards from crus at the time. Besides being active in Barolo, Ceretto also makes wine in Barbaresco and other areas in the Langhe.
