Hi,
I've read a bunch of the older posts dealing with getting the recipe numbers to come out reasonably close to the recipes in Jamil's "Brewing Classic Styles", but I think I have most of it figured out...with the exception of hop utilization. For some reason, my IBU numbers in BS2 are coming out much lower than what Jamil suggests in his recipe.
For example, when entering grains/hops, etc for an American Stout, the estimated gravity comes out pretty close using my equipment profile. However, he's shows a 70+ IBU using 1.4 ounces of 13%AA Horizon for 60 mins, and 1 oz of 10%AA Centennial for 5 mins. My alphas for these hops are different, but for grins I used his alpha numbers in the book just to see how it would come out, and I'm only coming out with just under 55 IBU's.
Anyone have any ideas what I might be doing wrong to have such a wide discrepancy?
