This incisive, Dagueneau-esque Sauvignon Blanc is drawn from vines aged between 20 and 50 years in the west-facing terroir of Les Puits aux Chiens. Sited on the right bank of the Cher River, it’s the highest point of the commune of Noyers, a cool terroir with shallow flint sands and white clay over Turonian limestone rock. Picked ripe, with barely any vestige of Sauvignon-ness, the grapes are pressed as whole bunches and ferment with indigenous yeasts in a selection of used barrels ranging from 228 to 500 litres. These vessels include those made using oak staves from the nearby Loches forest, selected and aged by Valentin Desloges himself (and coopered by François Frères). The wine ages for 12 months with a single racking and plenty of lees contact. It is bottled by gravity without filtration. Despite the negligible use of sulphur (1 g/L at the press and 2 g/L at bottling), it’s an incredibly focused, limpid, penetrating Sauvignon.
