Water Profile

Brewing Process

  1. Heat Strike Water to achieve Mash Temp of 66°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 66°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 60 minutes adding hops, spices, 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 18-20°C, oxygenating wort (inline or via aeration in fermenter).
  9. Rehydrate and pitch yeast as per manufacturer's recommendations.
  10. Ferment at 20°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 22°C for at least 48hrs to diacetyl rest.

If fining:

48hrs after FG is reached, Crash to 0-1°C.

Wait for the beer to clear naturally or fine and filter as required.

Keg or bottle condition - your choice? Aim for 2.5-2.6 volumes of CO2.
