Malolactic fermentation (or sometimes malolactic conversion or MLF) is a process in winemaking where tart-tasting malic acid, naturally present in grape must, is converted to softer-tasting lactic acid. Malolactic fermentation tends to create a rounder, fuller mouthfeel. It has been said that malic acid tastes of green apples. By contrast, lactic acid is richer and more buttery tasting. Grapes produced in cool regions tend to be high in acidity much of which comes from the contribution of malic acid. MLF is also thought to generally enhance the body and flavor persistence of wine, producing wines of greater palate softness and roundness. Many winemakers also feel that better integration of fruit and oak character can be achieved if MLF occurs during the time the wine is in barrel.
