Hop Alpha Acid Calculator

Our Alpha Acid Calculator is an easy one-stop tool for you to determine the amount of hops you need for your hop additions on brewdays when the alpha acid percentage of the hops you have does not match the percentage listed in the recipe. For example, look for the AA% on your package of hops, determine the amount of the addition in ounces, and find the expected AA% from your recipe to determine the new amount to contribute the same number of IBUs with the addition.
