Chardonnay is harvested throughout the cooler parts of day to preserve the quality and freshness of juices. Grapes from each site are pressed and separately vinified in temperature controlled fermenters to ensure the unique characteristics of each parcel is retained. Fifteen individual Chardonnay Cuvée are selected on the basis of subtle yet concentrated varietal flavour, balanced structure and generous palate length, all essential for the delicate and elegant Blanc de Blancs style. Following tirage and a secondary fermentation, essential parts of the Methode traditionnelle process, Chandon spends over forty months ageing on sedimentery yeast lees.
