More specifically: Some time ago I switched from fly sparge to batch sparge. My motivation was that I noticed quite a bit of channeling on deeper grain beds with the fly sparge. Batch is quicker and at least as efficient, but seems to generate a fair bit of trub. I'm guessing this comes from the fact that I have to settle the grain bed multiple times, and run off multiple times.
I vorlauf the friggin' bejesus out of it. I have a March pump and recirc the mash for at least a couple of minutes. Maybe some kind of inline filter would help me but I don't want to deal with the BS of having a stuck sparge because my filter is clogged.
My other thought is opening up the gap (currently 0.035) to something more like 0.050 so less of the malt gets powdered.
Yes? No? Maybe? What else?
