Okay, so I'm harvesting yeast for the first time. I'm getting pretty good separation between the yeast, trub, and beer water on top. Every time I pour to a new container, some of the trub comes with, so I keep doing this, getting less trub each time. Is it okay to keep some of the trub on the bottom? How much is acceptable?
Also, once the yeast completely settles, do you pour off the remaining liquid that's on top, or leave it on the yeast? I've read conflicting information on this. And, if there's still a little trub under the yeast at this point, is it okay to leave the yeast on it?
