Water treated with brewing salts to our Hoppy lite flavour profile: Ca=110, Mg=18, Na=16, Cl=50, SO4=100 (Basically Randy Mosher's ideal Pale Ale numbers with slightly less Sulphate and a Cl:S04 ratio of 1:2. We're not making a hoppy American beer here so we go a bit easy on accentuating bitterness.).
1.25 qt/lb mash thickness.
Single infusion mash at 154F for 90 mins.
Raise to 168F mashout temperature and hold for 10 mins.
~90 min fly sparge with ~5.6-5.8 pH water (measured at mash temperature).
Boil for 60 minutes, adding Whirlfloc and hops per schedule. Lid on at flameout, start chilling immediately.
Cool the wort quickly to 66F and transfer to fermenter.
Pitch yeast and ferment at 66-68F (wort temperature).
