What is ibu?

IBU stands for International Bitterness Units and is a measure of the bitterness in beer. It indicates the amount of iso-alpha acids, which are derived from hops, in a beer.

IBU is measured on a scale from 0 to over 100, with higher values indicating a more bitter taste in the beer. Beers with low IBU values are typically less bitter and have a milder taste, while beers with higher IBU values are more bitter and have a stronger taste.

It is important to note that the perceived bitterness of a beer can also be influenced by factors such as malt sweetness, alcohol content, and carbonation level, in addition to the actual IBU value.

Brewers use IBU measurements to help ensure consistency in the bitterness of their beers and to provide consumers with information about the taste profile of a particular beer.
