This is the question that will likely generate some debate.

I used to innoculate soon after primary was underway, on the
presumption that the ml bacteria would get a better start while the
alcohol was lower. Then, some fellow winemakers who profess to knowing
far more than I ever could suggested that I was risking some
undesirable volatile acidity by doing so (I am still uncertain of the
biologic basis for this). So I now innoculate late in primary - soon
before press. Not sure it really makes a difference, but done this two
years in a row now with no problems, so planning on continuing thus
until better information convinces me otherwise.

How about you? When do you innoculate with ml bacteria?

When, relative to primary fermentation, do you innoculate for MLF?
at start?
-or-
50% through?
75% through?
90% through?
