Question: 1 / 400

What is the unit used to measure the bitterness of beer?

SRM

ABV

IBU

The correct answer is IBU, which stands for International Bitterness Units. This unit of measurement quantifies the bitterness of beer primarily due to the presence of hops. The higher the IBU value, the more bitter the beer is perceived to be. This system helps brewers and consumers understand the level of hop bitterness in the beer, which is an essential attribute for many styles.

In the context of the other options, SRM refers to Standard Reference Method, which measures the color of the beer; ABV stands for Alcohol by Volume, indicating the percentage of alcohol in the beer; and OG refers to Original Gravity, which measures the specific gravity of the wort before fermentation. These units serve different purposes and do not convey bitterness, which is why IBU is the specific and appropriate choice for measuring the bitterness of beer.
