I've been reading posts, but do not know what MLF means.

I saw a glossary, but did not find this term.

Thanks,

it is the addition of malolactic bacteria to the wine to start a bacterial fermentation. it changes the malic acid in wine to lactic acid . this provides a better mouth fell to the wine. restrictions on ph and suflite content must be maintained before adding bacteria.

+ 1 on salcoco's post..

there are limits on PH, SO2 and ABV levels.

Malic acid is a harsh form of acid (much like that found in a grapefruit).

Lactic acid is a softer form of acid that can be found in milk.

Like Salcoco said above, Malolactic fermentation converts malic acid to lactic acid.

You may hear of a wine tasting buttery and soft? Most of the time this is due to a malolactic fermentation.
