Moet & Chandon Nectar Imperial Rose is rich, luscious and vibrant. This champagne is a spontaneous, radiant and romantic demi-sec style that reflects the Moet & Chandon expression. The MoÃ«t et Chandon champagne house was founded in 1743 by Claude MoÃ«t. It is the largest champagne house in France. The house produces large volumes of non-vintage wine under the White Star and Brut Imperial designations, but is best known for its premium brand Dom PÃ©rignon.
