Hops in beer is what keeps the malt from being too sweet. There are two types of acid in hops. They are alpha acid (AA) and beta acid (BA). The alpha acids are the precursor to beer bitterness. The beta acid is not as strong and loses its potency in the brewing process. The species of common hops are Humulus Lupulus. The flowers are dioecious (male and females grow on separate plants). Only the female cones are used for hops. The hops alpha and beta percentages are the weight in the mixture. The hops are a preservative, a head regulator, act as a natural filter and brings out the flavor of the beer.
It also cuts the sweetness of the malt.
