New Zealand Pale Ale

Based on Hopwired IPA

Add 500mg potassium metabisulphite to 20 gallons water to remove chlorine / chloramine (if required).
Water treated with brewing salts to our Hoppy flavour profile: Ca=110, Mg=18, Na=16, Cl=50, SO4=275 (Basically Randy Mosher's ideal Pale Ale numbers with slightly less Sulphate). For complete details on how to adjust your water, refer to our step by step Water Adjustment guide.
1.25 qt/lb mash thickness.
Single infusion mash at 152F for 90 mins.
Convoluted counterflow chiller
MORE INFORaise to 168F mashout temperature and hold for 10 mins.
~90 min fly sparge with ~5.6-5.8 pH water (measured at mash temperature). Collect 13.9 gallons.
Boil for 60 minutes, adding Whirlfloc and hops per schedule. Lid on at flameout after post-boil hops are added, start chilling immediately.
Cool the wort quickly to 66F (we use a one-pass convoluted counterflow chiller to quickly lock in hop flavour and aroma) and transfer to fermenter.
Aerate well. Pure oxygen from a tank may be used at a rate of 1 litre per minute for 60 seconds per 5 gallons.
Pitch yeast and ferment at 66-68F (wort temperature). We use modified stainless fermenting buckets in wine fridges.
Add dry hops once fermentation is nearing completion (i.e. 5 points from terminal gravity) and raise the temperature to 70-72F. In our case we simply turn off the fermenting fridges and allow the beer to naturally rise to room temperature. Steep hops for 3-5 days while fermentation finishes. Assume fermentation is done if the gravity does not change over ~3 days.
