Unexpectedly high efficiency?
So the last couple brews I’ve been getting really high efficiencies. Today I got an 87% BHE according to Brewers friend (after the brew day I adjusted final volume and BHE until it matched my OG). I use an igloo mash-tun with a bazooka tube, a MM3-pro that I scooped up for $50 set to 0.040”. I’m attempting a pilsner urquell clone and did a triple decoction (that took forever, and probably wasted my time since my decoctions were too thin). I then batch sparge to hit my pre boil volume.
Grains:
10 lb Weyermann floor malted Bohemian Pilsner
8 oz Weyermann acidulated malt
Final fermenter volume was 5.5 gallons and hit a 1.060 OG according to my tilt at 75 deg F.
I’m kind of shocked/don’t believe that number since by all accounts 80% is pretty exceptional unless you do BIAB. What I error am I likely making/overlooking in my calculation?
I will say that I pretty much have zero equipment losses from the kettle to fermenter and get a good tilt on my mash tun and get all the liquid out at the end of the sparge and press on the grain bed a bit to squeeze as much out as I reasonably can. Anyways that’s for reading and any thoughts.
