Ok I know Jayse has progressed beyond these brews, but I'm a year or two behind Jayse in my brewing and I figure its a rite of passage, so I did the Demon!
1.075, 70 IBU, dropped the crystal a bit and upped the melanoidin a bit, only did 10 minute hop additions, and used pretty much 100% Amarillo front to back (like Doc my scales must be dodgy, I ran out of Amarillo and substituted chinook for the flame out additions).
And....its bloody lovely. Such a rich malty fruity flavour, theres no way you would pick this as 7.5% cos the alcohol is hidden behind everything else. Really tropical fruit flavours and aromas, a bit of lychee, a bit of passionfruit, backed by a solid malt flavour. Definitely worth a go for anybody thinking about it.
