This cuvee is a blend of Cote des Blancs (Avize, Chouilly, Le Mesnil-sur-Oger and Vertus); Montagne de Reims (Ambonnay, Bouzy, Trepail, Verzenay, Verzy, Ludes et Rilly la Montage) and Vallee de la Marne (Mareuil-sur-Ay, Avenay Val d'Or, Cumieres, Dizy).Champagne Duval-Leroy was one of the first Champagne houses to be HVE3 certified and a multitude of sustainable practices are employed. Measures are taken to combat the run-off of rain water, to limit the pollution of both underground and superficial water; grass cover crops are grown and processes to combat soil erosion are employed. Biodiversity is positively encouraged, sustainable fertilisers are used and sexual confusion of predators takes place instead of insecticides. The plots and weather conditions encountered are carefully monitored, with soil testing and cartographic, computerised methods in place for full traceability of products used in the plots. Above all, preventative measures are in place to minimise the use of
products, which if necessary, are carefully chosen to have the least impact on the environment.
