Our roots can be traced back to GH Mumm, the leading international champagne brand in France. Established in California in the late 1970s, Mumm Napa follows traditional wine making techniques of its French heritage to create the finest, hand-crafted sparkling wines. Our dedication to quality has been rewarded with accolades and awards over the decades.
Mumm Napa holds true to Guy Devaux's original vision of creating the best possible sparkling wines in the United States.
