Notes
  • Take off 0.86gal prior to grain for sparge.
  • Mash recirculation power 45%
  • Add 1 oz mash hops
  • Add 3 grams ascorbic acid to mash
  • Goal mash pH 5.3.
  • Boil 50 minutes, wait 10 minutes before first hops. Let hard break simmer down before adding hops or they will get stuck on sides.
  • At 10 minutes remaining check pH for goal pH 4.9
  • Goal BU:GU ratio ~1.0, leave wiggle room for IBU contribution from knockout time to not go over 1.2.
  • Adjust knockout time to get to 170F and adjust whirlpool additions accordingly to keep IBU in range. If too long of a knockout drop whirlpool to below 165 for 0 IBU addition in whirlpool or shorten whirlpool time from 15 to 10 minutes.
  • Oxygenate wort for 30 seconds.
  • 210 billion yeast cells required
  • Each pack reporting at least 110B so ~20 g yeast total should do.
  • Ferment at only ~2-3 psi to not suppress ester formation
  • Once within 0.05 gravity points of FG raise temp to75 F and let PSI climb to 10.
  • Drop yeast after final gravity stable 3 days
  • Drop temp to 50F and dry hop.
  • Cold cash
  • Add lactic acid to keg for final beer pH 4.5
  • Add ascorbic acid to keg as antioxidant.
  • Purge keg with CO2
  • Force carb to 2.5 vol

    Brew Day##########:

    Kept at 153F mash consistently.
    Mash pH 5.2
    Post mash wort OG refractometer 1.057
    10 minutes left wort pH 5.1
    ~2ml lactic added
    Recheck pH 5, add 2ml more then hit pH 4.9
    Takes ~2.5 minutes to drop 212 ->165
    Whirlpool lasted about 15 minutes but only ~5 minutes of that was at 170F.
    final wort pH 4.9, OG refractometer 1.065

    Fermentation######

    Pitched around 74F. Fridge set to 66F.
    Day 0: tilt temp remained 73F for the next day.
    Day 1: Tilt temp reflecting fridge temp. Less than 1 day went from 1.064->1.019. Raised tempt to 72F. Opened dump valve to allow yeast to settle.
    Day 4: hit final gravity 1.015
    Day 7: s/p 3 days at final gravity, drop temp to 50 overnight
    Day 8: Dump yeast and dry hop. Ended up adding 1.49 oz riwaka, 1.31oz Amarillo, 1.39oz mosaic.
    Day 11: s/p 3 days dry hoping. Cold crash to 34F overnight.
    Day 12: Pull sample for pH. Worth pH was 4.9.

    Hypothetically: Dry hopping charge estimated raising pH by ~ 0.2. But Carbonating to 2.5 volumes will decrease pH by ~ 0.2-0.3. Already partially carbonated since fermenting under pressure and charged to 15 psi when cold crashing. Would assume its half way there so additional CO2 would drop pH ~0.1-0.15. So shooting for lactic addition to get to pH 4.6-4.7 for final pH once carbonated to 4.5. Estimated will need 3mL lactic acid.
    But prior to this pH was actually 4.3 so no lactic was added.
    Add ascorbic acid to keg 3/5th tsp
    Purge Keg with CO2
    Keg beer
    Force carb to 2.5 volumes. Currently measuring tilt temp at 40F so 12.3psi needed.

    Final beer: pH 4.3, FG 1.015, ABV 6.4. Kegged 9/13/25.
