- Bru N Water estimates mash PH will be 5.29. But I add all salts directly to mash and Bru N Water only lets me do salts split between mash and sparge.
- Actual mash PH taken with 20 minute sample was 5.41.
- Not sure I trust this PH meter. Very difficult to calibrate. PH readings jump all over the place. Jumped between 5.3 and 5.46. |

Notes
- Brewed on 1/23/21
- Mash water = 4.54 gallons (17.2 liters)
- Sparge water = 3.41 gallons (12.9 liters)
- Expecting pre-boil volume of 6.6 gallons (25 liters) or 6.86 gallons (25.9 liters) after 4% wort expansion, actually had 25.8 liters or 6.82 gallons.
- Did a protein rest at 122F for 15 minutes before going up to 154F mash temp
- Expecting mash efficiency of 84% (at expanded wort volume) which implies a pre boil gravity of 1.046. This is using grain father's mash efficiency calculator. Would be 83.13% on brewer's friend.
- Mash temp settled right it at ~154F
- Hit 10.3 plato pre boil gravity which converts to 1.041 vs. 1.046 target so 75% mash efficiency (76.6% on brewer's friend) vs. 84% expected.
- Expecting to boil down to 6.0 gallons (after wort cools) so boil-off tool estimates 1.051 OG, Actual original gravity reading was 11.9 plato which converts to 1.048 vs 1.051 expected. Extended boil to 90 minutes to get closer to target OG (this caused me to barely get 5 gallons into keg).
- After boil had ~6.XX gallons [XX.X liters] (expected 6.0 not expanded, 6.26 expanded) in the kettle and ~5.5 gallons made it into the fermenter.
- Pitched 2 smack packs and set fermentation chamber at 68F, slowly ramped up to 72F after a few days and held there.
- Packaged on 2/6/21, batch #50, FG was 1.013 (at 68F) which converts to 1.014 so 71% attenuation vs 74% avg. and 77% expected. Not doing starter most likely led to a slightly lower attenuation.
- Fill keg to 52.03 pounds = (1.014FG x 8.345 x 5 gallons) + 9.72 (empty keg weight + packaging hoses attached). Barely got 52 pounds (had to tip fermenter).
