A Blanc de Blancs Champagne is made from white grape varieties only. The white grape varieties authorised in AOC Champagne are: Chardonnay, Pinot Blanc, Arbanne, Petit Meslier and Fromenteau. These grape varieties are mainly cultivated in the sub-regions of the Côte des Blancs and Côte de Sézanne, and to a lesser extent in the Montagne de Reims and Vallée de la Marne.
Chardonnay, the most widely used grape, is well-suited to the production of autolytic styles. Its subtle apple and citrus aromas and flavours complement rather than compete with the cookie or pastry aromas from the autolysis of yeasts. Blanc de Blancs Champagne have an unmatched ageing potential.
