Using the water for mash a day before add juniper berries lemon peel and branches to the water and bring to 80 Deg C
let stand and cool over night
Taste water on brew day if flavour not strong enough keep branches and berries in water during mash as well
I've done this mash as a brew in a bag
Start with 15 litres and sparge with 2 litre over drained bag
You will loose about 2 litre to the grain
End up with 15 litre as no boil loss
Note - hop addition is a hop Tea. 250 ml boiling water over 15 gm of hops let stand for 15 min and add drains hop tea to mash
Ferment @ 28 C start day 1
Ferment @ 30 C day 3
Make only 15 litres at a time as is meant to be drank fresh
Can take on a sour taste if kept too long
note - make 18 litre as will loose some to grain and some to trub at end of ferment
IBU is not representative of the bitterness of the final product as the juniper branches and berries also contribute
