I adjusted the hop schedule from the original post as I will be doing a 3.25 boil versus the original 6.5. One of the subsequent posts showed an extract/smaller boil version that used this schedule (or something very similar). If I used the original schedule, I think the IBU's came in the 13-14 range. Increasing the time for some of the hops (as listed in my schedule) got me up to 16.4, which is close to the original, but still short.
I'm not sure how big on an impact going from 21 to 16 in IBU will really have on the perceived flavor of the bear.
