The “mid slopes” are customarily considered to offer an estate’s best grapes, so Géraldine and Richard proffer a Blanc de Noirs composed of 70% 2017 and 30% 2015 to make the point. It makes for a somewhat cerebral counterpoint to the pleasure-giving “Teroirs d’Écueil”, as the mineral charge is considerable and the dosage negligible (1.5 gm.). This is quite a mouthful.
