Terroir
Natural factors
- Valley floors and alluvial fans: colluvial-alluvial soils with low to medium-high skeleton content, predominantly Inceptisols.
- Continental alpine climate with annual precipitation of approximately 500 mm, among the lowest along the entire Alpine arc.
- High solar exposure: approximately 2,200 hours per year and an average solar radiation of 4,829 MJ/m²d, owing to limited cloud cover. (via Wikipedia · CC BY-SA 4.0)
Human factors
- Terraces built over centuries to wrest land for viticulture, with selection of indigenous varieties such as Mayolet, Fumin, Cornalin, Petit rouge, Premetta, Vuillermin, and Prié blanc. (via Wikipedia · CC BY-SA 4.0)
- Colluvial-alluvial soils (Inceptisols) on alluvial fans, comprising two calcareous types: eroded and skeletal on the slopes, and deep alluvial soils on the valley floor.
Terroir / wine link
- The marked diurnal temperature fluctuations of September and October, favored by the valley's geomorphology, contribute to defining the aromatic profile of the grapes.
