Notes
  • Brewed on 2/29/20
  • Mash water = 4.6 gallons (17.4 liters)
  • Sparge water = 3.39 gallons (12.8 liters)
  • Expecting pre-boil volume of 6.6 gallons (25 liters) or 6.86 gallons (25.9 liters) after 4% wort expansion, actually had just under 26 liters (I'd say 25.9).
  • Expecting mash efficiency of 84% (at expanded wort volume) which implies a pre boil gravity of 1.049
  • Mash temp settled right it at ~152F
  • Hit 11.8 plato pre boil gravity which converts to 1.048 vs. 1.049 target so 82% mash efficiency vs. 84% expected. Sparge was a bit faster with this batch. ~30 min.
  • Expecting to boil down to 6.0 gallons (after wort cools) so boil-off tool estimates 1.054 OG, Actual original gravity reading was 13.0 plato which converts to 1.053 vs 1.054 expected.
  • After boil had ~6.21 gallons (expected 6.0 not expanded so this is right on) in the kettle and ~5.5 gallons made it into the fermenter.
  • Pitched yeast starter and set fermentation chamber at 64F, changed to 65F 36 hours post brew day, did ~175B yeast cells instead of ~200 so 0.62 vs. 0.75 pitch rate
  • Packaged on 3/10/20, batch #42, FG was 1.013 (at 68F) which converts to 1.014 so 73% attenuation vs 75% avg. and 76% expected
  • Fill keg to 51.86 pounds = (1.014FG x 8.345 x 5 gallons) + 9.548 (empty keg weight). Was just able to get 51.86 pounds so volumes during brew day were spot on.
