With all due respect, why is this? Have you experimented to confirm this yourself? I know this is the oft-repeated "common knowledge" but I have done a few side-by-side tests with standard 60 minute addtition vs exact same amount as FWH. The percieved bitterness seemed the same to me and others that have tasted the experiments but there is something "different" about the FWH bittering. It's much more mellow and seems to hit the back off your tongue as it finishes.
The reason I did the experiments is that no one could tell me why hops that were boiled for over 60 minutes (FWH) should result in LESS bitterness than the standard 60 minute boil of bittering hops. So, why should a standard bittering charge boiled for 60 minutes give you "x" amount of IBU's but the same amount done as a FWH (and boiled longer than 60 minutes) only give you 20 minutes worth of IBU's?
I'm not trying to be combative, just so tired of the same old "truths" being repeated constantly and taken as gospel. Doesn't anybody else think to challenege these facts that just don't seem "right" or am I just some kind of rebellious freak?
