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.
