Yeast
Lallemand Lalbrew Voss Kveik Ale Yeast (1 Packet)
Mash Additions:
6.00g Calcium Chloride
5.00g Calcium Sulfate
3.00g Magnesium Sulfate
3-4mL 80% Lactic Acid (for pH Adjustment - requires pH Meter)
Brewing Process
- Heat Strike Water to achieve Mash Temp of 68°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 68°C for 45 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) to ~80°C. Turn the cooling off but continue whirlpooling.
- Add your Whirlpool hops and stand for 10 mins.
- Chill wort to the required pitching temperature of ~28°C. Transfer to fermenter and oxygenate wort (inline or via aeration in fermenter).
- Rehydrate and pitch yeast as per manufacturer's recommendations. Ferment at 30°C for the first 1-2 days. Yes. You read correctly; Ferment at 30°C!
- Aim to add the 1st dry hop addition on day 3 or ~4-8 Specific Gravity points (1.5-2.0Po) from the predicted Final Gravity - whichever comes 1st. The Final addition should be in before terminal gravity (FG) is reached at ~1-1.5 Plato (4-6 SG points) to FG.
- Once added, cap the fermentation (spunding valves are great for this), raise the fermentation set point to 33°C for at least 48hrs to diacetyl rest.
Fining/ Filtering
- 48-72hrs after FG is reached (i.e. Taste No Diacetyl), Crash to 5-6°C.
- Add preferred finings (Klarsol, Gelatine, etc.). This particular Yeast Strain is a high flocculator so may not require any fining orr filtration
- Crash cool to 0-1°C wait for the beer to clear naturally or filter as required.
- Keg or bottle condition - your choice? Aim for 2.55-2.65 volumes of CO2.
