Assembly : Chardonnay, Pinot Noir, Meunier. Winemaking: Collection is based on a selection of plots chosen in the heart of the Champagne region, adapted to its identity, with priority given to sustainable viticultural practices. To bring freshness even further and balance the beautiful ripeness of the harvests, Louis Roederer Collection is composed of a “Perpetual Reserve” which brings new sensations, both tactile and gustatory: the wine thus finds more breadth, depth, material and relief; its more enveloping, fleshier texture enhances its complexity. Collection is also composed of Reserve Wines aged in wood.
