The grapes for the Prelude cuvee come exclusively from fruit grown in Grand Cru classified vineyards. 50% Chardonnay grapes from the Cote des Blancs, including Avize and Le Mesnil sur Oger, and 50% Pinot Noir from the Montagne de Reims area, including Mailly and Ambonnay. There are 17 named Grands Crus in Champagne, covering approximately 9% of the vineyard's surface. A selection of these is used in Prelude, each Grand Cru site bringing precise characters to the blend such as minerality, structure, or fruitness. All Taittinger’s vineyards are managed under the watchful eye of Christelle Rinvelle, Champagne Taittinger’s highly regarded vineyard manager. Taittinger manages its vineyards with sustainability at the heart of every decision, meticulously cultivating every vine. They are HVE certified and accredited to Viticulture Durable En Champagne.
