Area of the Great Whites - Côte des Blancs, Coteaux du Morin & Côte de Sézanne

The name Côte des Blancs (literally “side of white”) could allude to the white grapes that thrive here, but in fact it refers to the calcareous soil that characterises the otherwise diverse terroirs of the general area of the Côte des Blancs, Coteaux du Morin, Côte de Sézanne, Montgueux and Vitryat. The latter two subregions have a dedicated map, given their distance from the other three areas.
The Côte des Blancs includes 6 from the total of 17 grand cru villages in Champagne: Avize, Chouilly, Cramant, Le Mesnil-sur-Oger, Oger and Oiry.

In contrast to the terroir of Côte des Blancs in the north of this region, the Côte de Sézanne, despite sitting on the same chalk seam, has large amounts of marl and sand. The slightly higher percentage of clay in this subsoil produces a floral, fruity style of champagne from chardonnay grapes, less refined than the traditional style blanc de blancs (white from white) wines encountered further north. Although chardonnay still dominates at 77%, pinot noir (18%) and meunier (5%) are also grown in this subregion. The Coteaux du Morin is less chardonnay dominated, with a varietal breakdown of 47% meunier, 40% chardonnay and 13% pinot noir. It is known for its diverse, yet still chalky, soils that produce elegant champagnes. The wines of the Côte des Blancs, using 98% chardonnay and only 2% pinot noir, are crisp and thirst-quenching, so it is natural that they are designated on the map in a summery yellow shade that reminds us of sun and sand.
