Champagne Pommery is a Champagne house located in Reims. The house was founded as Pommery & Greno in 1858 by Alexandre Louis Pommery and Narcisse Greno with the primary business being wool trading. Under the guidance of Alexandre's widow, Louise Pommery, the firm was dedicated to Champagne production and soon became one of the region's largest Champagne brands. Champagne Pommery was the first house to commercialize a brut Champagne in 1874. It is possible to visit this Champagne cellar and also the Villa Demoiselle, just in front of Champagne Pommery House in Reims.
