The intensity and simultaneous lightness of Ruinart Blanc de Blancs is achieved by using a blend of 100% chardonnay, mainly from premiers crus in Côte des Blancs (69%) and Montagne de Reims (31%), and 20-25% reserve wines. The chalkiness of the soil allows for a pure expression of the grape’s flavours, and ageing in the crayères develops its aromatic richness.
