If I were to use Super Kleer KC or something of that nature, would that precipiate out all of the yeast? I need enough viable yeast to bottle condition/carbonate in a couple of weeks. Would repitching at bottling/priming do the trick?
it might do just that. Personally, I wouldn't bother fining it. I've made 2 batches and haven't fined it, and it comes out crystal clear. That montrachet yeast is really highly flocculating, and the apple juice itself is crystal clear to start with, so...mine comes out looking like white wine.
