- Using Chicago tap water for mash (~52%) to keep ion levels, specifically calcium, higher (~34ppm) during the mash
- Using distilled water for sparge (~48%) to dilute total ion levels down to target which will be sub 18 ppm across the board
- Adding 1ml of lactic acid to the mash water to lower PH below 6, normally add 2 ml but sparge water was distilled so PH was 7 vs. my tap water which is 7.9 |

Notes
- Brewed on 1/1/20
- Took mash water and sparge water volumes from the Grainfather brew session tool
- Expecting mash efficiency of 85% which implies a pre boil gravity of 1.042
- Mash temp settled right it at ~152F
- Hit 11.8 plato pre boil gravity which converts to 1.048 vs. 1.042 target so ~93% mash efficiency vs. 85% expected. Very slow sparge, close to an hour (**upon further research it seems with grain bills under 10 pounds the standard grainfather pipe length can create slow/stuck sparges. Mine did not get stuck but ran really slow and increased my efficiency). Also only had ~6.3 (24 liters) gallons pre-boil, been getting a bit under 6.6 frequently, going to assume lower for now on maybe 6.4-6.5.
- Expecting to boil down to ~6 (5.9) gallons so boil-off tool estimates 1.047 OG. Actual original gravity reading was 12.8 plato which converts to 1.052 (would have expected 1.053 with new assumptions) vs 1.047 expected.
- After boil had ~5.7 (21.5 liters) gallons (expected ~5.9) in the kettle and ~5.5 gallons made it into the fermenter
- Pitched the yeast starter and set fermentation chamber at 54F, held here for 12 days and then raised to 65F for a 3 day diacetyl rest.
- Packaged on 1/15/20, batch #39, FG was 1.013 (at 68F) which converts to 1.014 so 72% attenuation vs 72% avg. and 74% expected
