Stéphane Coquillette Diane Brut Blanc de Blancs

Stéphane Coquillette Diane Brut Blanc de Blancs is the clearest Chardonnay-focused bottle in a range that brings together fruit from several of Champagne’s most recognisable villages. The family estate is based in Chouilly Grand Cru at the northern end of the Côte des Blancs. Stéphane Coquillette represents the fourth generation, with Diane and Louis identified by the domaine as the fifth. The estate works a little over six hectares across the Côte des Blancs, Grande Vallée de la Marne and Montagne de Reims, using only estate-grown fruit for its Champagnes. Diane narrows that broader vineyard picture to Chardonnay. The cuvée is 100% Chardonnay from Chouilly and Cuis, making it the most direct route into the white-grape side of the estate. That position is especially useful because the wider range also includes Pinot Noir from Aÿ and Mareuil-sur-Aÿ, giving buyers a clear way to compare grape and origin within one family domaine. For a first bottle, L’Entrecœur provides the broadest introduction by bringing Pinot Noir and Chardonnay together. Diane is the next logical step when Chardonnay is the priority, while Les Clés moves in the opposite direction towards pure Aÿ Pinot Noir. Marie-Aimer covers the rosé style, and the vintage wines add harvest-specific detail. Choose Stéphane Coquillette Diane Brut Blanc de Blancs when you want the estate’s most straightforward Côte des Blancs expression. Its appeal lies in its clarity: one grape, two named Chardonnay villages and a direct connection to the family’s own vineyards. For buyers trying to understand how this grower moves between Chardonnay and Pinot Noir across different parts of Champagne, Diane is the obvious white-grape reference point.
