Bernard Defaix produces Chardonnay from Chablis, the northernmost region of Bourgogne. The winery's portfolio spans the appellation's hierarchy: entry-level Chablis, Grand Cru selections from Bougros and Vaudésir, and the mineral-driven whites that define the region. Chablis Grand Cru 'Bougros' and 'Vaudésir' represent the upper tier of the appellation, where Chardonnay achieves complexity and structure on limestone-rich soils. The standard Chablis offers the characteristic acidity and flinty character expected from the region's cooler climate. Wine Enthusiast, Wine Advocate, Wine Spectator, and Decanter have all assessed the winery's offerings, reflecting its standing within the appellation.
