6% acidity About The Taste: We use the French Champagne Method to create the California Sparkling Wine that we then handcraft into our crisp white wine vinegar using the traditional Orleans Method and barrel aging. KATZ Sparkling Wine Vinegar, with its pristine clarity, is made from 100% Suisun Valley, California Chardonnay. Its desirable low acidity level of 6%, creates a tart, full-bodied vinegar with “soft” edges and a fruity aroma. Offering crisp and pleasant acidity, hints of vanilla from the oak and subtle nuances of melon and cucumber in the finish, its clean taste lends itself to a myriad of culinary uses. Well-made vinegar and acid in general really acts as the yin in much of the yang of good cooking.
