What does IBU measure in beer?

• A. Alcohol content
• B. Color intensity
• C. International bitterness unit
• D. Sugar content

Answer: (C)

The term IBU, or International Bitterness Unit, is a standard measurement used to quantify the level of bitterness in beer. It measures the concentration of iso-alpha acids, which are the compounds responsible for the bitter flavor in beer, resulting from the hops used during brewing. A higher IBU value indicates a more bitter beer, while a lower value denotes a less bitter taste. Understanding the significance of IBU is essential for beer appreciation and brewing, as it directly affects flavor profile and balance. Brewers often consider IBU levels when formulating recipes to achieve the desired taste experience, particularly when balancing hops with malt sweetness and other flavor components. The other options provided do not relate to IBU: alcohol content is measured in ABV (alcohol by volume), color intensity is typically indicated by SRM (Standard Reference Method) or EBC (European Brewery Convention), and sugar content is assessed through various other measures, none of which are linked to the bitterness measurement that IBU represents.
