Stéphane Coquillette produces Champagne from the region's premier terroirs, drawing on the classic grapes of the appellation. The house works with Pinot Noir, Chardonnay, and Pinot Meunier to craft its range, which includes a Brut Rosé from the Grand Cru site of Chouilly—a wine built on Pinot Noir's structure and depth. The flagship Brut Champagne Grand Cru 'Chouilly' blends all three varieties, while the Carte d'Or Brut Premier Cru showcases Chardonnay's mineral precision. Both Wine Spectator and Wine Advocate have rated the house's releases, reflecting the technical rigor evident in each cuvée. The wines reflect Champagne's hallmark balance of acidity, complexity, and refinement.
