Notes

for initial water from HLT, (80L for both the strike & Decoction water) add 50ml AMS, and Campden.

Top up decocted mash with the heated strike water (85degC) to make 80L liquid in Mash half way through decoction stage.

Ferment at 20degC, cold crash to 6degC once fermentation ends (usually after 5 days).
