Malolactic Bacteria

Malolactic bacteria convert malic acid to lactic acid during malolactic fermentation (MLF). MFL is an optional step in the production of red wines that results in reduced acidity (desirable in high acid wine), higher pH, and greater flavor complexity.

Some commercially available bacteria cultures can be added directly to the wine to initiate malolactic fermentation. The cultures come in packets. The packet should be stored in the freezer.
