Which hops are considered low alpha acid hops?

The choice of Fuggle, Hallertau, and Liberty as low alpha acid hops is correct because these varieties typically exhibit alpha acid levels that are significantly lower than the more commonly used high alpha acid hops found in modern brewing.

Fuggle hops, for instance, are traditional English hops known for their mild and earthy flavor profile, and their alpha acid content generally ranges from 3% to 5%. Hallertau hops, primarily used in German-style lagers and wheat beers, also have a low alpha acid range, usually between 3% to 5.5%. Similarly, Liberty hops, an American variety designed for German brewing styles, feature a low alpha acid level typically around 4% to 5%.

In contrast, other choices contain hops that are known for their higher alpha acid percentages. For example, Chinook, Citra, and Galaxy are often used for their intense flavors and high bitterness, making them unsuitable for classification as low alpha acid hops. Columbus and Bravo also have notable alpha acid levels and are frequently selected for their strong bittering potential. Pride of Ringwood and Super Alpha are known higher alpha varieties as well, often used for their bold bittering capabilities.
