Citric acid

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 citric acid.  It lends a tart flavor to the wine and contributes to its character, balance and texture — or mouthfeel. Use as per instructions in wine recipes. Popular with bath balms.
