Located about eleven kilometers southwest of Alba, the Barolo wine-growing region is situated in a horseshoe-shaped valley. The vines thrive on slopes at altitudes ranging from 300 to 500 meters above sea level. A large portion of the vineyards faces south, though recently, north-facing vineyards have also been permitted.
The region is generally divided into two areas. The Serralunga Valley lies in the east, with soils made up of sand and sandstone, as well as elements like calcium, iron, phosphorus, and potassium. The central valley in the west encompasses the municipalities of Barolo and La Morra, with soils containing higher levels of clay, manganese, and magnesium oxide. 87% of Barolo is produced in the five original municipalities—Barolo, La Morra, Castiglione Falletto, Serralunga d'Alba, and Monforte d'Alba—established in 1896. However, there are now a total of 11 Barolo municipalities, across which the 181 Crus are spread. The best vineyard sites include Arborina, Arione, Cannubi, Cerequio, Brunate, Bussia, Fisaco, Francia, La Serra, Lazzarito, Monprivato, Ornato, Ravera, Rocche, Sarmazza, and Vigna Rionda.
