Beta acid in hops for brewing – what you should know.


Beta acid hops brewing is a lesser-known aspect of beer production, yet it plays a crucial role in shaping the final product. In this blog post, we’ll explore the importance of beta acids in hops and their influence on beer taste and quality.


Hops are essential ingredients in beer, containing several critical compounds such as alpha acids, beta acids, and essential oils. While alpha acids contribute to bitterness and essential oils add aroma, beta acids are responsible for other aspects of beer’s taste and stability.

How would pure beta acid taste like?

Pure beta acid would taste astringent and somewhat bitter. However, this bitterness is different from that of alpha acids, as it is perceived as a more subtle and smooth sensation rather than an intense and sharp bitterness.

Influence on beer taste

Beta acids contribute to the overall flavor and stability of beer. While they do not provide the same level of bitterness as alpha acids, they can oxidize over time, resulting in a more subtle and smooth bitterness. Additionally, beta acids have antimicrobial properties that help protect beer from spoilage.

A few examples of beta acid levels in hops

Hops with different beta acid levels can be used for various brewing purposes. Here are some examples of hops with both high and low beta acid levels:

  1. High beta acid hops:
    • Nugget (4-6%)
    • Chinook (3-4%)
    • Galena (7-9%)
  2. Low beta acid hops:
    • Saaz (4-6%)
    • Tettnanger (3-5%)
    • East Kent Golding (2-4%)


In conclusion, beta acids play a vital role in hops brewing, contributing to the taste and stability of beer. Although they are less prominent than alpha acids, understanding their impact on beer’s flavor profile and their antimicrobial properties is essential for brewers. By recognizing the importance of beta acid hops brewing, we can better appreciate the nuances and complexities of our favorite brews.
