Notes
  • Brewed on 8/18/18
  • Expecting mash efficiency of 78% which implies a pre boil gravity of 1.056
  • Initial PH was 5.8, added 3ml of lactic acid and second reading was 5.55, added 1 more ml of lactic acid and reading didn't change, then added 1 more ml of lactic acid and final reading was 5.5. **Update. Think my issue was not mixing the lactic acid with the water prior to doughing in.
  • Mash temp fluctuated a bit but was able to settle it at ~154F
  • Hit 13.1 plato pre boil gravity which converts to 1.053 vs. 1.056 target so 74% mash efficiency vs. 78% expected
  • Original gravity reading was 17.1 plato which converts to 1.070
  • After boil had ~6.0 gallons in the kettle and ~5.5 gallons made it into the fermenter
  • Pitched 1 smack pack of wyeast 1056; started fermentation at 64F. The two thermometers had different readings so ferm temp was in the range of 64-66F and held it there.
  • Packaged (too early) on 8/27/18, once out and ready to package noticed some airlock activity but decided to keg anyways since the hydrometer did not taste too sweet. Attenuation was at 72% and expected 78%. Probably could have let this one go and got to 75-78%.
