Mumm Napa Brut Prestige

The Brut Prestige grapes are harvested by hand during the crisp morning hours to ensure they arrive at the winery in pristine condition. Fermentation is conducted at cool temperatures, mainly in stainless steel tanks to preserve freshness and fruit intensity. A few selected lots are aged in French oak barrels to add depth, complexity and spiciness to the final blend. After initial fermentation, the art of the blending begins. Our winemakers find the perfect blend of wines to create our signature taste. Then the finished blend is bottled for the second fermentation. An average of 18 months' yeast aging adds complexity, contributing subtle bread dough flavors and layers of creaminess. The wine is disgorged as a brut style and a dosage is added back to balance the wine's acidity. Brut Prestige then ages another 3 months on the cork to fully marry the dosage to the base wine.
