Which of the following is true about the solubility of beta acids?

Beta acids, which are found in hops, are characterized by their low solubility in water. They remain largely non-soluble throughout the brewing process, including during boiling. This is an important distinction, as it affects their role in beer production. While alpha acids, on the other hand, are responsible for bitterness and are soluble during the boil, beta acids do not contribute significantly to the bitterness or flavor profile of the finished beer due to their poor solubility.

The other options do not align with the characteristics of beta acids: they do not dissolve easily in water, they do not become soluble during the boil, and they do not contribute to increases in bitterness in the same way alpha acids do. Understanding the solubility of these compounds helps brewers make informed decisions about their hop usage and the overall flavor profile of the beer.
