IBUs, or international bettering units, is a system for measuring the amount of bitter compounds found in beer. Most of these bitter compounds come from hops, but some can come from tannins and roasted grains. IBUs are very important for brewers during recipe formulation, a brewer will use IBUs to balance against residual malt (grain) sweetness, and ensure each beer has an appropriate amount of bitterness for its style. That said, the IBUs of any given beer won’t tell anyone – even a brewer – much about the beer’s actual flavour. Most people attribute high IBUs to high bitterness of a beer, but this is not necessarily accurate. The best way to gauge the bitterness of a beer is to ask our bartender, or simply try it for yourself!
