Notes


PRIOR to BREW DAY

  • Attach torpedo buoy with filter attachment to fermentation keg
  • Sanitize fermentation keg
  • Attach torpedo buoy with filter attachment to serving keg
  • Fill serving keg 99.99% full with Starsan (tip and inject Starsan
    until water escapes from gas QD)
  • Collect RO water needed for brew day
  • Mill grains

    Yeast Starter

  • None. Use dry yeast.

    PREHEAT MASH TUN##

  • Heat 5 gallons of brewing liquor to 180-degrees in HLT
  • Transfer 2 gallons of 180-degree water to the MLT
  • Close lid and let sit for 10 minutes
  • During this time, add remaining brewing liquor to HLT and heat to 158-degrees
  • Return the 2 gallons from the MLT back into the HLT (so the HLT now contains the full amount of brewing liquor)
  • Continue heating HLT until it reaches 158-degrees
  • Recirculate HLT water through HERMS pump, HERMS coil, back into HLT for 5 or so minutes to stabilize the loop

    MASH

  • Transfer strike water from HLT to MLT
  • Add mash salts/acid
  • Dough in and stir
  • Start HERMS recirculation
  • Add a drop or two of lactic acid to sparge water

    BOIL

  • Add kettle salts
  • Boil timer settings: nE=3, AD=10, T1=60, T2=15, T3=10
  • Use stainless/tubular hop spider to contain hop residue
  • Add table sugar at 10 minutes left in boil
  • When there are 10 minutes left in the boil sanitize Tilt hydrometer
  • When fermentation keg is around 1/3 full, add Fermcap-S drops
  • Start pitching yeast progressively while wort level is low
  • Pitch dry yeast directly onto wort (no need to oxygenate when using dry yeast)
  • When filling is complete, put sanitized Tilt hydrometer into fermenter

    STC-1000 settings:
    SP0=64, DH0=47
    SP1=64, DH1=1
    SP2=67, DH2=72
    SP3=72, DH3=0

    FERMENTATION

  • Use an OPEN FERMENT to maximize esters
  • Remove blowoff valve from fermentation keg
  • LOOSELY cover the fermenter to reduce possibility of spoiling organisms from falling in.
  • Pitch at 63 degrees
  • Ferment at 64 degrees for 2 days
  • On morning of day 3, add an airlock
  • Ramp to 72 degrees over 3 days
  • Keep at 72 degrees until fermentation is complete

    PACKAGING

  • Pressurize serving keg to 9 psi
  • Do a closed-loop/pressurized transfer to serving keg
  • Set keezer pressure to 18 psi of CO2 to 2.9 volumes of CO2 at 43 degrees (F)
