Malic Acid (ML)


Malolactic fermentation (secondary or MLF) occurs when a strain of lactic acid bacteria is introduced into a finished primary fermented product. The lactic acid bacteria convert the tart-tasting malic acid to a soft-tasting lactic acid during secondary fermentation. The Malic Acid test is useful for acid adjustments prior to primary fermentation as well as monitoring conversion during secondary fermentation.
