The plots where Giacometto’s red grape varieties grow feature morainic soils from the Quaternary Period. These soils are typical of a subalpine zone known as the Canavese, which is centered on the town of Caluso. The soils are sandy and stony, composed of pebbles originating from the glacier on the Mont Blanc massif. They are rich in mineral salts and yield remarkable acidity and sapidity in the wines of the zone. The IndoEuropean Celtic tribes were the first to cultivate this vine in the area.
