I'm developing a recipe for an imperial chocolate stout (trying to come up with an Abraxus clone). The recipe I'm working with came out of Craft Beer & Brewing magazine and was used at WeldWerks in Colorado. The base recipe has 1.5 oz of Magnum Hops @ 10.5% AA for an IBU of 45. However, when I put this into BS3, I get an IBU estimate of 24.7. If I go back to BS2, I get 43.1. I'm at 8200' elevation which is programmed into my equipment profile and am using a 90 min boil.
Would you expect the impact of elevation to reduce the IBU's by this much? Just want to be sure before I amp things up on this recipe!
Thanks,
Mike
