The reason that most craft beer has such a high IBU is to hide the off-flavors. If your local small brewery suddenly has a "special" IPA on their menu for a short time, it is because they brewed a bad batch of something else and spiked it with a ton of hops in order to make it sell-able. There is a lot of really bad beer out there. The really good stuff is the target of these buy-outs.
