Rehydrate yeast, added gypsum, sodium chloride to reach a balanced profile. Didnt want it to high in calcium/magnesium as ive used late hops to bitter/flavour and aroma (as per Mr Maltys website ). Going tom be more hop flavour and aroma then the profile however it wont be overpowering due to hop selection. Dont use american hops for this style.
Mash19lt @67c sparge 14lt and top up to desired level.
Ph 5.2/5.4 is target.
Never used mangrove jack yeast will give it ago. Otherwise Danstar windor/nottinghmam or safale will be a good choice.
