Terroir
Natural factors
- Glacial origin of the soils: the glaciers of Monte Rosa formed morene that connect the mountain to the plain.
- Soils composed of argille, kaolins, and tufi at the surface, more compact on the plateau, gravelly on the western slope.
- Abundance of dissolved mineral salts in the soil, absorbed by the vine and expressed as sapidity in the grape.
Human factors
- Viticultural origins documented from the 1st century AD: the funerary stone of Vibius Crispus (Tiberian era) and Pliny's reference to 'spionia', ancestor of Spanna (the local Nebbiolo).
Product characteristics
- Soils of morenica origin containing argille, kaolins, and tufi impart sapidity to the wine.
- Soils rich in dissolved mineral salts, absorbed by the roots, add sapidity to the grape.
