I get huge amounts of break, and leave too much wort behind. I use a converted Sankey keg as a boil kettle, with weld-less fittings (fitted reasonably high as they don't sit we'll on the curved part of the lower wall) and a straight/level copper tube inside reaching to the centre, with a t-style bazooka screen stainless mesh. The screens sit pretty high off the bottom, and I'm losing a huge amount of wort (1-1.5 gallons?) when I drain to my fermenter. Granted, not all of that is actually liquid wort. Some is the whole hops debris. And there is so much break material that realistically I'm not sure how much more wort I could extract anyway without sucking it up. My question is thus: how much break material are others getting from a 5 gallon all grain recipe boil, and how concerned are you with some of it making it into the fermenter in exchange for being able to take more wort from the kettle? I have a copper elbow that I only used once (to drop the bazooka screens down to the very bottom of the kettle) but then they are thoroughly immersed in the thick break/hop gunk, and I sucked half of it up.
Would love your thoughts. I'm tired of filling my fermenter and being under volume, and I don't want to waste grain and hops by just upping my recipe scale to cater for the wastage.
