Target Water Profile
City of Chicago (North) - Q4 2017
Ca+2 Mg+2 Na+ Cl- SO4-2 HCO3-
36 12 8 14 25 127
Adding 3 grams of gypsum, 3 grams of calcium chloride, 2 ml of lactic acid to the mash to achieve the following:

Ca2 - 82, Mg - 12, Na - 8, CI - 57.9, SO4 - 75.8, HCO - 80.904

Expected mash PH = 5.38. Initially mash PH was reading close to 5.5.

Had to add an extra 1ml of lactic acid. Then actual PH reading came out to 5.37.

1ml of lactic acid in 6-7 gallons of sparge water only dropped PH down to 7.5-7.75 from 8

Notes
  • Hit 153F mash temp vs. 152F target
  • Hit 1.046 for pre boil gravity vs. 1.039 expected
  • Hit 1.061 vs. 1056 expected original gravity (so 80% vs. 70% expected brewhouse efficiency)
  • Also ended with 5.5 gallons in fermentor vs. 5.25 expected
  • Used 1 smack pack of wyeast and started fermentation at 65F
  • Final gravity was 1.012 measured at 68F, this converts to 1.013 so 78% attenuation vs. 72% expected
