I'm having a few friends round tonight for a few games of poker and some homebrew - tomorrow I'm hoping that one or two of them will stick around to help me out with two brews as my girlfriend (who gets very bored when I brew!) is going to be working tomorrow all day

I will be brewing two beers; One of them is going to be the starting point for my house bitter - I plan to use this recipe as a starting point, and tweak it every time I brew it until it is perfect. The other is going to be a strong (7.5 to 10% abv) bitter, but I need help deciding on my recipes
My 'Henry's Best' recipe, is based on Dave Line's recipe for Harvey's Sussex Best but uses different hops because a) I want it to be original and b) I've got a few bags of hops in the freezer which need using up!
