Notes
  • Homebrew shop only had 7 month old 2278 czech pils yeast so had to call an audible and went with 2308
  • Brewed on 12/5/20
  • Mash water = 4.17 gallons (15.8 liters)
  • Sparge water = 4.14 gallons (15.7 liters)
  • Expecting pre-boil volume of 6.6 gallons (25 liters) or 6.86 gallons (25.9 liters) after 4% wort expansion, actually had 26.75 liters (could have easily got to 27 liters) or 7.07 gallons.
  • Expecting mash efficiency of 91% (at expanded wort volume) which implies a pre boil gravity of 1.047. This is using grain father's mash efficiency calculator. Would be 90.49% on brewer's friend.
  • Mash temp settled right it at ~152F
  • Hit 10.0 plato pre boil gravity which converts to 1.040 vs. 1.047 target so ~81% mash efficiency (at 7 gallons) vs. 91% expected. Sparge moved much faster than expected and reduced efficiency. Not sure why my sparge lengths have been inconsistent.
  • Expecting to boil down to 6.0 gallons (after wort cools) so boil-off tool estimates 1.052 OG, Actual original gravity reading was 12.0 plato which converts to 1.048 vs 1.052 expected. Extended boil to 2 hours to get to 1.048.
  • After boil had ~6.XX gallons [XX.X liters] (expected 6.0 not expanded, 6.26 expanded) in the kettle and ~5.75 gallons made it into the fermenter.
  • Pitched the yeast starter and set fermentation chamber at 50F, started to slowly ramp up for D rest on day 8, then started crash down on day 11 (12/16) for gelatin addition. Will go down to 45F. Had suck back issues once I got below 50.
  • Packaged on 12/18/20, batch #49, FG was 1.014 (at 53F) which converts to 1.013 so 72% attenuation vs 72% avg. and 72% expected
  • Fill keg to 51.99 pounds = (1.013FG x 8.345 x 5 gallons) + 9.72 (empty keg weight + packaging hoses attached). Easily got ~52 pounds into keg.
