So I finally got to use my new Cereal Killer mill on my Vienna lager yesterday. I’m wondering if my crush was a little too fine. I adjusted the gap to the suggested .037" using a feeler gauge. First thing that was weird was that 10lbs of grain absorbed over 2 gallons of water. I started with 4.5g of strike water and ended up with 2.3g in the kettle.
I sparged with 5 gallons and only got about 4.5 gallons out but realized the “mush” was blocking the bazooka screen so I scraped some of that away from the screen and the remaining half gallon (and a whole bunch of grain/meal drained out. Is this normal to have the last 0.5g or so blocked?
Total efficiency was around 77% at the end of the boil. I ended up with a bit of ground meal/flour type material in the kettle. I realize this is probably unavoidable to a certain degree since the bazooka screen can only stop the husks from getting through. I did vorlauf about 3 times and I was still getting a little bit in my runoff.
