Mirabelle North Coast Sparkling Wine. Mirabelle is Schramsberg's Multi-Vintage Brut sparkling wine. It is exclusively crafted with Chardonnay and Pinot Noir grapes grown in our cool climate North Coast vineyards. Twenty-five percent of barreled reserve wine add depth and roundness to the fruitful core wines. Bottle fermentation and a minimum two years of aging on our historic, hand-dug, hillside caves create the tiny bubbles and complex flavors. Cheers! - Hugh Davies, Vintner. Alc. 12.8% by vol. Produced and bottled by Schramsberg Vineyards, Calistoga, CA.
