MALOLACTICFERMENTATION

Malolactic fermentation

Malolactic fermentation is a process in winemaking in which tart-tasting malic acid, naturally present in grape must, is converted to softer-tasting lactic acid. Malolactic fermentation often occurs shortly after the end of the primary fermentation but can sometimes run concurrently with it. The process is standard for most red wine production and for some white grape varieties such as Chardonnay, where it can impart a "buttery" flavor from diacetyl, a by-product of the reaction.
