Terroir
Natural factors
- Glacial origin of the soils: the glaciers of Monte Rosa formed moraines that bridge the mountains and the plain.
- Soils composed of clays, kaolins, and tuffs at the surface, more compact on the plateau, and gravelly on the western slope.
Human factors
- Viticultural origins documented from the 1st century CE: the funerary stele of Vibius Crispus (Tiberian era) and Pliny's mention of 'spionia', the ancestor of Spanna (the local Nebbiolo).
Product characteristics
- Soils rich in dissolved mineral salts absorbed by the vine roots add savouriness to the grapes.
- Soils of morainic origin, with clays, kaolins, and tuffs, impart savouriness to the wine.
