Ok, please forgive me if this is somewhere else (I'm sure it is, just didn't know how to search for it). I'm about to foray into yeast ranching to get a stash of pacman going. I understand the process, but here is my question: say after my wash I have about 4 jars or so of slurry. I understand that those are good for a couple of months to over six months, ymmv. But what if I take one of those jars and pitch to a starter for a new batch- then harvest again after primary. can this be done ad nauseum, or is there a limit to the number of times you can re-harvest? If yes, why? Just trying to figure out the mechanics of it all...
