Yeast
Lallemand BRY-97 West Coast Ale Yeast (1 Packet)
Mash Additions:
3.00g Calcium Chloride
1.50g Magnesium Sulfate
6.00g Calcium Sulfate
3-4mL 80% Lactic Acid (for pH Adjustment - requires pH Meter)
Brewing Process
- Heat Strike Water to achieve Mash Temp of 67°C (~6°C above strike).
- Add minerals to Strike or Foundation water.
- 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).
- Mash at 67°C for 60 mins. Confirm no residual starches remain.
- 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).
- Boil for 60 minutes adding hops and kettle finings at indicated times.
- At End Of Boil, whirlpool while chilling (immersion style) or for 10 mins, stand 15 mins or until chilled to pitching temperature.
- Transfer to fermenter at 18-20°C, oxygenating wort (inline or via aeration in fermenter).
- Rehydrate and pitch yeast as per manufacturer's recommendations. Ferment at 18°C for the first 3-4 days.
- Aim to add the dry hop addition on day 5 or ~4-8 Specific Gravity points (1.5-2.0Po) from predicted Final Gravity.
- Once added, 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 2.55-2.65 volumes of CO2.
