The question is whether you need MLF culture
If the cider finishes tasting pretty good, except for an intense sour apple gumball finish (high malic acid) which does not fade in a couple months due to natural MLF (or you do not want to wait a couple months), then yes, adding culture is helpful. Otherwise you dont need it.
How long should it take for the MLF to kick off after inoculation? Is there a usual lag? It has been 3 days and I'm not seeing bubbles.
