The Champagne House with its headquarters in Vertus was founded in 1859 by the two families Duval and Leroy. It is still family-owned and is now run by Carol Duval-Leroy, the sixth generation of the family. Sandrine Logette-Jardin is the cellar master. The vineyards cover 200 hectares, 40% of which are in Grand Cru and Premier Cru sites in the Montagne de Reims and Côte des Blancs. The vines are cultivated in an environmentally friendly manner, which is also documented by solar panels on the new cellar building. The champagnes have an aromatic, fruity style. For example, the qualities "Blanc de Chardonnay", "Femme de Champagne", "Brut Rosé", "Premier Cru", and "Vintage" are produced, as well as two organically certified wines. A Duval-Leroy champagne was the favourite brand of the German actor Heinrich George (1893-1946). Together with ALCAN Packaging Capsules, the special bottle closure MAESTRO was developed and presented to the public in 2009.
