Korbel Sweet Rose Rosé Sparkling Wine from CaliforniaThe broad array of red grapes used in the Korbel Sweet Rose blend give us an incredibly diverse selection of blending alternatives. Varieties like Pinot Noir, Gamay and Zinfandel give us light bright wines with high levels of acidity. The Sangiovese is more intensely aromatic, while the syrah contributes a deeper color and more tannin for body and richness.
