Jean Claude Courtault produces Chardonnay from Chablis, the northernmost region of Bourgogne. The winery's portfolio spans the appellation's hierarchy: a village-level Chablis, the Premier Cru 'Beauroy', and the Grand Cru 'Valmur'. Chablis Chardonnay is defined by mineral precision and bracing acidity, shaped by the region's cool climate and limestone-rich soils. The 'Valmur' Grand Cru represents the apex of this terroir expression, while 'Beauroy' offers a more accessible entry to the Premier Cru tier. Wine Advocate, Wine Enthusiast, Decanter, and Wine Spectator have all assessed the winery's releases.
