Les Choisilles is named after the type of black flint abundant in the parcels that gift this wine. The main vineyards involved are Les Epinais, La Taille aux Loups and Clos Renard. The bedrock across these sites is tuffeau (limestone), and the vines range in age from 30 to 90 years. Chidaine notes that these deep-rooted vines transmit an elegant minerality from the black flint soils.
