Bérêche & Fils produces champagne from the region's premier terroirs. The house works with the classic blend of Chardonnay, Pinot Noir, and Pinot Meunier across its cuvées. The Champagne Grand Cru 'Mailly' marries Chardonnay with both Pinot varieties, while the Grand Cru 'Aÿ' leads with Pinot Noir and Pinot Meunier alongside Chardonnay. A single-varietal expression, Les Monts Fournois, showcases pure Chardonnay. Wine Spectator, Wine Advocate, and Decanter have rated these releases. The house's approach reflects Champagne's tradition of blending to achieve complexity and balance across distinct vineyard sites.
