A Brief Guide to Hops, and Hop Varieties

Hops, that little green flower that you add to your beer. They are vital most beer styles. They add a bitterness that balances the sweet malty wort, flavors and aromas that range from spicy and piney to fruity and citrusy, and provide anti spoiling agents in their bitter oils to help keep beer from becoming infected.

The longer hops are boiled, the more bitterness they add, but the less aroma and flavor they add. After 15 minutes, your aroma contributions will be almost none, and after 20 the flavor drops off. Between 21 and 44 minutes is kind of a dead zone where you aren’t getting great use from your bittering additions and not getting flavor or aroma either. 45-60 minutes is where you’ll get the most from your bittering hops.

Evaluating Hop Information for Brew Planning

When looking at a hop package in your local homebrew store, or browsing hops online, you may see a few words with percentages after them. These typically refer to Alpha Acids (AA), Beta Acids (BA), and Cohumulones.

Hop Acids(1)

Alpha Acids contribute the bitterness to your beer through boiling. The higher the Alpha Acid content, the more bitterness you’ll get. So something with an AA of 4% like a noble hop, won’t add as much as a hop with 9% AA.

Beta Acids are a bit more tricky. They don’t add any bitterness to your beer when boiled and only contribute a bitterness when beer becomes oxidized during long periods of aging or lagering.

Cohumulones are a type of Alpha Acid, (the other relevant one being Humulones). Cohumulones add a harsher bitterness, while Humulones add a softer bitterness. These aren’t always listed on hop varieties so if you don’t see it, you can assume it’s an average amount. If it is particularly low or high it may be listed.

Being familiar with how these acids work with your beer will help determine hops to use in recipe formulation along side their flavor and aroma profiles. Now let’s go over some popular hops in the homebrewing community.
