Domaine Bersan operates in Bourgogne, the French region that defines Chardonnay and Pinot Noir. The winery's portfolio centers on two classical expressions: Chablis, a mineral Chardonnay from the region's northernmost appellation, and Cuvée Louis Bersan Irancy, a Pinot Noir from the lesser-known Irancy zone south of Auxerre. A third offering, Bourgogne Côtes d'Auxerre Chardonnay, rounds out the range with a regional take on the white grape. Decanter and Wine Enthusiast have rated these wines, with the Chablis and both Chardonnay bottlings earning particular marks of distinction. The winery's focus on Chardonnay and Pinot Noir—the twin pillars of Burgundian viticulture—reflects the region's uncompromising commitment to terroir-driven winemaking.
