My last few brews have had very low yield to fermenter, primarily due to break and trub left in the kettle--up to 2 gallons' worth!

I'm hitting my target gravities, and getting good yields from my mashes (75%+), with average boil-off and top-up consistent with my pre-brew volume calculations.

I suppose I should be glad that I'm getting really clear beer, but at a 20% loss of product, I'm not very happy about it. I thought perhaps I was using too much rice hull (always keep it below 5%) and perhaps not letting the grain bed settle enough during sparge, so today, I didn't use any. I had a good mash, looked like I got a good clear wort, and I had hopes for a full batch's yield, but no change.

Maybe my crush is too coarse?

What type of filter are you using? Braid? False bottom? PVC?

I wouldn't worry about getting break material in the fermenter. It will settle to the bottom during fermentation and shouldn't cause any flavor issues.

Ditto that.

Also, are you using leaf hops?

Have to agree. I used to worry about break material, etc in the fermenter, but after the first couple years, I just a coarse filter to keep the hop cones out.

I just dump everything into the fermenter. My beers still end up clear and I don't give up 2 gallons of my precious brew.

I use a false bottom. I vorlauf until I get a clear wort flow, then I fly sparge. I don't filter from kettle to fermenter.

Jon,

No, I use pellet.

For you guys that are throwing it all in...I'm assuming you're leaving behind the hop trub?

Are you seeing head retention loss due to protein content?

I throw it all in... until it gets solid. No worries about hop gunk in the fermenter.
