Notes
Hopped beyond the point at which IBUs are measurable, only the most hardened palate will get beyond Jack Hammer's intensely resinous pithy bitterness and to the grapefruit, orange zest and dry biscuity malt beyond. You could brew this with less hops, but really, why would you bother?
Tagline: Ruthless India Pale Ale. Hoppy. Bitter. Hoppy.
First brewed: 06/2012
Food pairing: Phall Curry; Pork burrito with a habanero and mango chilli salsa; Ginger and grapefruit poundcake
Brewer's tips: Be aware that this is probably the hoppiest beer you will ever make. Make sure you use fresh hops, for a massive fresh grapefruit hit. Have everything else in your store cupboard, and buy your hops last, as close to brew day as possible!
