Joséphine Dubois produces wines from Bourgogne, the French region celebrated for its expression of terroir through Chardonnay and Pinot Noir. The winery's Chablis, made from Chardonnay, represents the mineral precision characteristic of that northern subregion. Les Saint Secret Les Clos Chablis Grand Cru, also Chardonnay-based, draws from one of Chablis's most prestigious vineyard classifications, where limestone-rich soils impart distinctive structure and complexity. The Grand Réserve Bourgogne Pinot Noir rounds out the portfolio with the silky, nuanced character typical of Burgundy's signature red variety. Wine Spectator has rated these offerings, reflecting their standing within the broader Burgundy landscape.
