Why test for Malic Acid in wine?
Quantitative determination of malic acid is important in the manufacture of wine & beer. L-Malic acid levels decrease during fermentation and in the final stages of ripening malic acid decomposes and the grape can become over ripe. Therefore malic acid is used in the wine industry to determine the ripeness and variety of grapes.
