Stéphane Rousset’s vineyards are in Crozes-Hermitage’s northern communes of Erôme, Gervans and Crozes-Hermitage, including the legendary Les Picaudières. The hill structures and soil types differ significantly throughout the appellation with various exposures on moderate to very steep rock terraces. Rousset’s Marsanne grows mostly on loess topsoil and granite bedrock. The Crozes-Hermitage red wine terroirs are largely on granite with some variations of igneous and metamorphic rock. Across the river, in Tournon, two adjacent blocks of St. Joseph grow on extremely steep granite slopes. Whites are whole cluster pressed, fermented in concrete, mostly aged in steel without malolactic with remaining in oak. The reds are partial stem inclusion and are fermented in steel and then racked to barrel or tank where they age for about a year.
