Mumm Napa was established in the late 1970s.

Mumm Sparkling wines are made from grapes sourced from high-quality sparkling wine regions throughout the state of California. These wines are made in the méthode traditionnelle (traditional method), which is the same method used to make sparkling wines in Champagne. This specialized process imparts toasty notes and creamy texture to complement the fruit-forward style of these wines that’s well-suited to spontaneous everyday celebrations or mixing into cocktails.

Mumm Napa wines are a true expression of Napa, which can be tasted in the ripe fruit flavors and creamy texture typical of the Mumm Napa style. These wines spend an average of two years aging on the lees as part of the méthode traditionnelle sparkling winemaking process, giving them extra complexity, toastier flavors and creamier texture. These special wines elevate meals with friends or add extra sparkle to celebratory occasions.

Mumm Napa and Mumm Sparkling wines are made using an intricate process called Méthode Traditionnelle—the same time-honored approach used to make French Champagnes. Read more about our winemaking here.

Sparkling wines can be stored either upright or on their sides. Still wines should be stored on their sides to keep the cork moist.

We recommend storing our wines around 55°F for best quality, but the most important part of wine storage is avoiding too much temperature fluctuation, so wherever you store your bottles, try to keep the temperature consistent and ideally below 70°F.

This will vary depending on the wines. Our core wines generally taste their best within a year or two, but our Reserve wines can often age 5 to 10 years or even longer. Recommended aging is listed in the tasting notes for specific wines.
