I'm using the default AA% for the hops - perhaps that's where the difference is?
Using whole or pellets? I try to input the actual AA% for each hop. I use whole hops almost exclusively and BeerTools defaults to pellets, so I have to go in and change to whole hop utilization. The IBU levels drop a bit using whole hops, and the Jamil show did not say the hops form as far as I remember. I am hopeful that as long as you followed the hops schedule, you will get the great results that Jamil and Tasty did on the podcast.
I just brewed this today,( I listened to the podcast, and put it all in BeerTools) I changed the utilization curve from "basic" which gave me 61.1 IBU, to Rager and got 71.4 IBU. Tinseth put me at 55 IBU, which is what the brewery quotes as the bitterness level. Hmmm, I never really thought about the wide range of the utilization curves before, and my numbers were sort of opposite yours? Weird that BeerSmith and BeerTools would give different numbers using the same curve. (I did sub Magnum (14%) for the Galena/Nugget(13%), so nothing odd there. Otherwise the Willamette(5.2 %) and NB(7.8%) were pretty much with the recipe.)
Well, the brew went perfect, hit 1.067 chilled to 65f and pitched a pint of Wyeast 1968 I got from a local brewpub this morning. Blowing off in 4 hours. Can't wait to try this one!
