Malic Acid, 2 oz

 3.4g per gallon adjusts acidity by +.1%. It will lower pH less than will tartaric acid. Malic is less sour than tartaric acid and can be used to make acid adjustments in Rieslings Gewurztraminer and Muscat varieties though many winemakers still prefer to use tartaric acid in these situations. You would not want to add Malic acid to any wine that will undergo a malolactic fermentation. As a note only half of the artificially added malic acid will convert to lactic acid during a malolactic fermentation.
