Mirabelle Blanc de Blancs (white from whites) is made from Chardonnay, one of the classic three grape varietals used in champagne. The grapes are grown in the unique pockets of California’s North Coast, including the Napa-Carneros, Sonoma Coast, Mendocino County, and Marin County. After bottle fermentation and two years of aging en tirage, subsequent trials determine the ideal dosage to finish this lively, fruitful style.
