It’s the vineyard that most needs care and attention, but it can offer excellent Nebbiolo grapes for elegant, mineral and long-living Roeros.

Bric Valdiana: soil
In Bric Valdiana vineyard two types of soil, typical of Roero, can be identified: at the top of the hill there is a layer of soil that can be traced back to the sands of Asti, yellow-greyish; it is largely composed of sand and silt, with calcium concentration in the order of 5-7%. This complex was formed about 4.5 million years ago by a shallow sea bottom (200 m) and densely populated by mollusks (710 species have been classified).
In the middle band of the hill, sand of Asti mix with older geological formations: the clays of Lugagnano, which have been originated 5,5 million years ago by a medium deep seafloor (500m), therefore less oxygenated. The soil is mostly composed by clay and silt, it has a bluish-gray color, and it’s moderately calcareous (10-15%).
This type of soil ensures sufficient water supply in summer and a balanced availability of nutrients, very important for a production of quality grapes.
The texture of the soil has on average 35% sand, 40% silt, 25% clay with a total calcium content of 12%.
