NV Champagne Ruinart Brut Blanc de Blancs

100% Chardonnay from various years; 20 to 25% of which are reserve wines from the 2 previous years.  A large majority of Premiers Crus from the Côte des Blancs and Montagne de Reims vineyards for aromatic refinement, supplemented by Sézannais wines known to provide maturity. Finally, several wines from the north of the Vesle valley give a light, fresh touch.
