Régnard produces Chardonnay from Chablis, the northernmost region of Bourgogne. The vineyard's portfolio spans the appellation's hierarchy: entry-level Chablis, the single-vineyard Chablis Saint Pierre, and the Grand Cru Les Preuses, which draws from one of Chablis's most prestigious sites. Les Preuses, with its mineral-driven character shaped by Kimmeridgian limestone soils, represents the apex of the range. Chablis Chardonnay at this latitude expresses steely acidity and flinty notes, with complexity that deepens in the Grand Cru designations. Wine Spectator, Wine Enthusiast, and Decanter have assessed Régnard's releases across this vertical.
