Overview

Malic acid is a dicarboxylic acid common in the plant kingdom and contributes primarily to the acidity of green apple juice. It is present in pears, apples, grapes and most wines. Although the amount present decreases as the fruit ripens, it contributes a tart taste to wine. Malic acid is converted to lactic acid, which is much milder, through the malolactic fermentation used in winemaking.
