Castelnau champagnes are sourced from across the vast selection of 150 of the region’s cru vineyards. Prestigious grand crus from the Côte des Blancs and Montagne de Reims combine with a rich tapestry of crus from the Vallée de la Marne, Massif de Saint-Thierry and Côte des Bars, not forgetting the young, dynamic regions of Vitryat and Sézanne. Meunier, Chardonnay and Pinot Noir come from the entire Champagne region and provide the Cellar Master with a rich portfolio of flavours.
