A complex profile due in part to a special dosage of Brandy that emphasizes vanilla and toasty yeast. This blends with a pleasant fruit and mild floral character to provide a harmonious bouquet. Winemakers sometimes add a small batch of liquid, called a "dosage," to champagne immediately before the final bottling. The dosage of brandy in Cook's Brut Grand Reserve adds depth and complexity along with smooth vanilla and oak flavors.
