“Dom Ruinart, always 100% Chardonnay from grand cru vineyards, was created by Bertrand Mure, who was part of the extended Ruinart family. The sources of the base wines vary with each vintage but generally it's about two-thirds from the Côte des Blancs and one-third from the northern part of the Montagne de Reims.” Jancis Robinson
