Valentin Desloges’ flagship white comes from the Bel Air terroir, a south-facing site on the left bank of the Cher River and home to the Domaine’s oldest Sauvignon Blanc vines (some reaching 60 years). It’s not simply the older, lower-yielding vines that contribute to this cuvée’s ravishing intensity. The soils are dominated by red clay, just below a layer of flinty sands, which add to the wine’s spicy generosity and textural breadth. The winemaking is not so different from the Chapitre I. However, this wine fermented in barrel and matured (for 18 months instead of 12) in ex-Coche-Dury barrels with 20% new oak from the Domaine’s tailor-made barrels.
