The sparkling wines of Mirabelle, second label of Schramsberg, have shown steady improvement and seriousness of intent over the years. The Mirabelle sparklers are always non-vintage, whereas the products under the Schramsberg label always have a vintage date. Today’s particular wine is the Mirabelle Brut Rosé, North Coast, a blend of 55 percent chardonnay grapes and 45 percent pinot noir. Eighty-six percent of the wine is from the 2010 vintage, the rest made up of aged reserve lots. The designation is North Coast because the grapes derive from multiple counties north of San Francisco, mainly Napa and Sonoma but also Mendocino and Marin. Made in the traditional champagne method of second fermentation in the bottle, Mirabelle Brut Rosé offers a beautiful light copper-salmon color and a teeming upward stream of tiny bubbles; aromas of fresh and dried strawberries and raspberries, lime peel and guava open to notes of limestone and chalk and hints of quince and ginger. This sparkling wine is quite dry, very crisp and lively, not only with effervescent but crystalline acidity, though the texture is almost creamy; spicy yet subdued red berry and stone-fruit flavors are heightened by the burgeoning limestone and flint minerality, while the finish is long, elegant and steely. 12.8 percent alcohol. Excellent. About $27.
