Notes
  • add 10g of Mandarin Hops as bittering addition to bring IBU from 14 to 22. IBU target fell short due to decreased hops utilization in a high-gravity brewing.
  • For water profile, following J. Palmers suggestions on section 'Brewing your hometown pilsner'. Since ions in Kamloop's water is low, just adding some salts to increase Ca levels to 50ppm.
  • Topped up the high gravity wort to 21 liters (5.5 gals) with 3 gallons of Great Value natural spring water with ions: HCO3:250, Ca:72, Cl:2, Mg:18, Na:7, SO4:52. Note that high level of HCO3 is ok since that's how Munich water profile is like as well as Ca at 70s.
  • pre boil OG for 13.2 liters (3.5gals) mash measured to be 1.062 at 16C (60F) implying 60% ish conversion efficiency which below expectation. Hence, conversion efficiency might not be constant after all down to 2l/kg wort-to-grist ratio as suggested in J. Palmer's book based on experimental data.
  • pre-boil OG of 1.062 for V=13.2 liters corresponds to OG of 1.039 for V=21 liters.
