1- I'll be using a 32L boiler and I'm determined to get between 21-22L (hence the volume alterations)
2- With regard to the recipe this is my first attempt at my own after doing a few based on messer Wheelers book
I'm aiming for something with a bit of punch, very hoppy e.g. Joker IPA, Proper job, Ghost ship etc but I want something around the 4.1-.4.4% Mark. I think an IBU of 70 would get me there but Im happy to be completely wrong

Would much appreciate any advice, thanks in advance
