* HUGELY MASSIVE DISCLAIMER: Not all beers list IBUs. Not all beers with IBU information have that information recorded at RateBeer. IBUs reported by the brewer may not be accurate - the quantity of bittering hops that brewers put into their beer is not what's actually extracted into the beer. IBUs may also vary from batch to batch. Furthermore IBUs are not a very good indicator of perceived bitterness. A beer's perceived bitterness is a combination of many factors of a beer and the taster. So take this list with a big huge grain of salt.
