The vineyard ‘Côte Rozier’ sits north of the village of Ampuis, on the same, east-facing flank of hillside as ‘La Landonne.’ Steeply graded, the plot’s soils are mostly schist, with some mica pieces; classic ‘Brune’ terroir. The family farms three small parcels within ‘Rozier,’ one of which was planted in 1942 by winemaker Christophe Billon’s grandfather.
