Water Profile

Brewing Process

  1. Heat Strike Water to achieve Mash Temp of 67°C (~6°C above strike).
  2. Add minerals to Strike or Foundation water.
  3. Begin mashing in. Measure the mash pH (once all the grain is added) to achieve 5.2-5.5 (adjust with 1 mL additions of 88% lactic acid, if required).
  4. Mash at 67°C for 60 mins. Confirm no residual starches remain.
  5. Batch sparge with 78°C water until kettle volume is achieved (or stop runoff when the last runnings drop below 1.010 and pH rises above 5.75).
  6. Boil for 90 minutes adding hops and kettle finings at indicated times.
  7. At End Of Boil, whirlpool while chilling (immersion style) or for 10 mins, stand 15 mins or until chilled to pitching temperature.
  8. Transfer to fermenter at 17-18°C, oxygenating wort (inline or via aeration in fermenter).
  9. Rehydrate and pitch yeast as per manufacturer's recommendations. Ferment at 18°C until 4-6 SG points (1-1.5Po) from FG, then cap the fermentation (spunding valves are great for this). Raise the fermentation set point to 20°C for at least 48hrs to diacetyl rest.

If fining:

  1. 48hrs after FG is reached, Crash to 0-1°C. Do not filter, or cold-condition or the yeast will drop out of suspension (this beer should be cloudy).
  2. Keg or bottle as desired. Aim for 2.7-2.8 volumes of CO2.
