Gladfield Hefeweizen
Batch Size
30L Kettle Full; ~23L (in fermenter)
Ingredients
Malts
- 2.75kg Gladfield Pilsner Malt (48.3%)
- 2.40kg Gladfield Wheat Malt (42.1%)
- 0.35kg Harraway’s Flaked Wheat (6.1%)
- 0.20kg Gladfield Oat Hulls (3.5%)
Hops
- 60min – 20g Spalt Select 5.0% aa (10 IBU)
Yeast
Lallemand Munich Classic Hefeweizen yeast (1 packet)
Mash Additions:
5.00g Calcium Chloride
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 90 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 17-18°C, oxygenating wort (inline or via aeration in fermenter).
- 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:
- 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).
- Keg or bottle as desired. Aim for 2.7-2.8 volumes of CO2.
