Wine Acids

The acid content of a wine helps to determine its color, intensity, brightness and flavor, among other characteristics. While all grapes contain a certain amount of naturally occurring acid, winemakers check the pH level of the wine throughout the fermentation process and often refine their products by adding tartaric acid, malic acid, citric acid or an acid blend containing some combination of the three. These wine acids lend a tart flavor to the wine and contribute to its character, balance and texture -- or mouthfeel. Ascorbic acid, which acts as a natural preservative by preventing oxidation, is sometimes added during filtration, just prior to bottling.
