1. In the North-West part, at altitudes between 320 and 360m above sea level, the soil is almost totally sandy (80% of the total), very loose and a little calcareous, with strong draining capacity. Sands of marine origin are mixed with other more recent, formed by fluvial deposits. These lands, mostly covered with woods and
orchards, are voted to the cultivation of white grapes.
2. Under the Rocche, a typical geological formation of Roero, at lower elevations
(320 to 250 m above sea level), the matrix is formed by sandy soil, but it has a more ancient formation
(3.5 million years ago) and a marine origin
(Pliocene sands), which is the reason of the presence of many different species of fossil mollusks. The soil is rich in mineral elements, ideal for Arneis and fruity, soft and salty red wines.
3. When this matrix is combined with a silty soil, richer in clay and more calcareous
(which originated from a deeper sea bottom), you have the ideal soil conditions for well structured red wines.
In the territory of Montà
three main types of soil
can be identified.
