Malolactic fermentation is the conversion of malic acid to lactic acid by bacteria from the lactic acid bacteria family. Lactic acid is less acidic than malic acid, which in turn decreases acidity and helps to soften and/or round out some of the flavors in wine.

PurePitch^® Next Generation, an evolution of White Labs’ PurePitch^® – the most superior and consistent yeast on the market – has been made even better with new packaging powered by FlexCell^® Technology for ease of use and a pitch rate resulting in a foolproof fermentation every time.
