Beta acid is one of the two primary resins that are present in hops, the other being alpha acid. Although beta acid imparts only a small portion of the bitterness that alpha acid provides, it is important because, as the alpha acid bitterness breaks down over time during fermentation and storage, beta acid creates a sharper bitterness in beer as oxidation occurs. Unlike alpha acid, beta acid does not isomerize during the boil and is primarily responsible for the hop aroma in a beer.
