Controlling Flavors in Wine by Measuring Organic and Inorganic Acids

Application Note 273: Higher Resolution Separation of Organic Acids and Common Inorganic Anions in Wine applies this approach to four red and white wine samples. Testing to validate the repeatability and accuracy of this method shows that this is a reliable method for determining important organic and inorganic acids in wine. Such determination is helpful because the flavors imparted by wine are in part due to its organic acid composition, which contributes to the overall acidity and tartness of a wine. The maturation of a wine also can be followed by changes in organic acid composition that can create flavors that are either pleasing or undesirable.
