The house's iconic cuvée, first created in 1876 for the Tsar of Russia, Cristal is produced from 45 exceptional plots, spread over 7 Grand Crus of the Montagne de Reims, the Vallée de la Marne and the Côte des Blancs. Cristal 2015 thus originates from 3 emblematic vineyards of the house: 1/3 from the vineyards of "la Rivière", 1/3 from "la Montagne" and 1/3 from "la Côte". The crus used to make this exceptional champagne are Verzenay, Verzy, Beaumont-sur-Vesle, Ay, Avize, Mesnil-sur-Oger and Cramant. The year 2015 had a mild and wet winter and a hot and particularly dry summer. The rainy spells recorded in the second half of August saved the vineyard, thus preserving the freshness and concentration of the grapes. The harvest was quantitative and of exceptional quality for this year marking the recognition of the Champagne region as a UNESCO World Heritage Site.
