Beta acids

Beta acids are natural compounds found in hops, the flowering plant used in brewing beer. They contribute to the beer's bitterness and aroma, especially during the brewing process. When hops are boiled, beta acids can break down and transform into compounds called cohumulones, which enhance bitterness and stability. Unlike alpha acids, which are the primary source of bitterness through isomerization, beta acids are less soluble and less bitter on their own but can influence the beer's flavor profile over time. Overall, beta acids play a subtle but important role in shaping the beer's taste and aroma characteristics.
