Italy's smallest and highest wine DOC in the Western Alps between Mont Blanc and the Gran Paradiso, producing indigenous Petit Rouge, Fumin, Cornalin, and Prié Blanc from terraced gneiss and granite soils at 500–1,300 metres altitude. The steep valley sides and extreme alpine microclimate create conditions for small quantities of highly characterful wine from ancient pre-phylloxera varieties found nowhere else on earth — a viticultural time capsule.
