The territory of Piedmont occupies the north-west of the peninsula and extends to the foot of the Alps, while its vineyard is concentrated in the provinces of Cuneo and Asti. The wines of Piedmont are born on the hills which chant a good part of the region. It is also this type of relief that characterizes the Langhe and Roero areas, home to the most famous wines. Although Barbera is the most widespread grape variety, Nebbiolo, another local variety, is responsible for the great Piedmont reds, which are called Barolo and Barbaresco. These two names are at the peak of the consideration given to the products of the Italian vineyard. However, the Barbera and, to a lesser extent, the Dolcetto have gained esteem in ambitious hands, in the many denominations bordering the Piedmontese vineyards. In white, the main grape variety is Moscato, which shapes the famous sparkling wines of Asti.
