I've been looking to brew a Black IPA and that link is very helpful. Just one question; why are my IBU's so far off when I plug this into Beersmith. I plugged the hop additions in identical and the AA% are the same. I have both batches set to 5 Gallons, any more and the IBU'a go down of course. I'm sure I'm missing something.
