Gloria Ferrer produces sparkling wines in Los Carneros, where cool maritime air and morning fog shape the character of Chardonnay and Pinot Noir. The winery's portfolio centers on traditional-method cuvées: the Reserve Cuvée Extra Brut, a refined blend rated 92.5 by prestige critics including Wine Enthusiast, Wine Advocate, Decanter, Wine Spectator, and Falstaff; the Royal Cuvée Rosé, which balances the same grape varieties at 91.0; and the Vista Brut, also at 91.0. Each wine reflects the region's signature cool-climate precision—high acidity, mineral tension, and the complexity that extended aging on the lees imparts. Los Carneros' terroir, straddling Napa and Sonoma, has long favored sparkling wine production, and these cuvées demonstrate the region's aptitude for the style.
