The Roero, situated on the left orographic bank of the Tanaro river, is characterised by fossiliferous marly sands with a sandy or sandy-silty texture.
The Langhe, on the right orographic bank of the Tanaro, also have marly soils but with a greater proportion of silt and, above all, clay compared to the Roero.
The soils of the Roero are relatively younger owing to greater river erosion and the continuous, more recent uplift of the land and the underlying seabed.
The final wine produced from the grapes can display very different characteristics depending on the soil, the lie of the land, the vineyard's aspect, the altitude, and the viticultural practices employed.
Human factors
Alba wine is obtained by skilfully blending Nebbiolo and Barbera, the two grape varieties most widely cultivated in the production zone, according to the vineyard of origin and the winemaking objective pursued.
The Albese area, encompassing the Langhe and Roero, was until the middle of the last century an almost exclusively agricultural territory.
