What is the primary characteristic of a beer with an IBU of 23-35?

A beer with an IBU (International Bitterness Units) of 23-35 is characterized by moderate bitterness. This range typically indicates that the beer will have a noticeable hop bitterness that is balanced and not overwhelming. At this level of IBUs, the bitterness can be perceived as a pleasant aspect of the beer, contributing to the overall flavor profile without dominating it.

Moderate bitterness allows for more complexity in the taste, and it tends to complement the malt sweetness, giving a well-rounded flavor experience. The perception of bitterness can vary based on other elements in the beer, such as malt sweetness, alcohol content, and carbonation, but within this IBU range, brews usually achieve a harmonious balance.

The other options describe levels of bitterness that either exceed or fall short of this profile. Very bitter would suggest a higher IBU range, while low bitterness would imply fewer hop flavors and a lack of the characteristic bite that comes with moderate bitterness. Sweetness indicates a focus on malt flavors, which would not typically align with a moderate bitterness profile.
