Louis Billard farms tiny hillside parcels in Saint-Aubin, bringing an unusually high pedigree to his work — he spends his days at Domaine de la Romanée-Conti, and you can feel that precision in the glass. Les Castets is bright and finely cut: citrus, white peach, a touch of almond, all wrapped in that chalky, saline minerality that defines this corner of Burgundy.Fermented slowly, aged with a gentle touch of oak, the wine stays focused and elegant — nothing flashy, just honest, expressive Chardonnay from a rising name to watch. Drink now for clarity or hold a few years for extra depth.
