So I pressed 2 weeks ago and then 24hours or so later I racked off gross lees. My wine has been in airlock carboys since and all I've added so for is some tartaric to bring up my low acid levels a little no sullfites yet other than pre-fermentation. I'm sitting at around 3.3-4ph right now and am wondering A. if MLF is mandatory/recommend and B. If its too late to introduce my own bacteria.
Thanks
