I've brewed variations on this recipe 4 or 5 times
Always, by necessity mostly, substituted Hersbrucker for MtHood and Chinook for Columbus - they work fine but who knows how close to the original??
Since the first time I have gradually been knocking the OG and bitterness levels back... now when I make it, its more a rye APA and is generally a tiny bit drier - but the ratios of everything have stayed fundamentally the same as the original recipe. its just a good flavour mix that I dont think needs any messing with, so all I do is make the experience little less intense and a little less likely to make me fall off my chair.
Last time with 1272 which I like a lot more than 1056
