Somebody please correct me if I'm wrong, but from my admittedly limited understanding, I thought FWH gave the same # of actual IBUs as a standard bittering addition. It's just the perceived bitterness that is different.
And I think the 20 min reference is referring to the effect it has on taste/aroma, but again I am not even close to an expert on FWH. This was actually the first recipe I designed using it.
