Stop and Smell the Hops: 4 Fun Facts About Hops and Your Senses

By Bryan Roth @bryandroth

Summer is a time for vacations and travel – things I have been busy with lately.

There has been plenty of time sitting in airports, on planes and by the pool, so filling it up with worthwhile reading makes everything a little easier. Naturally, I’ve been opting for something a little more educational than the normal easy beach reading.

Among the books I’ve been working through has been Stan Hieronymus’ For the Love of Hops, an incredible compendium of research and interviews on the history and science of this important beer ingredient. It’s chock-full of incredible information, most of which goes above and beyond my beer-loving head.

However, that doesn’t mean there aren’t some easy, accessible things to learn from Hieronymous’ work. Instead of sifting through the pages yourself, here are just four cool tidbits I learned from the book about hops and our senses.

1. The Nose Knows

Ever wonder why so many hop heads adore the process of sticking their nose in a glass filled with an IPA? It’s because our noses are pivotal in our beer drinking experience. While we have four receptor types in our brain geared toward sight, we have about 350 active receptors for smell. Like the unique snowflake you are, not every person has same active receptors, which helps result in our wide range of palates and ability of sense.

2. Frankie Says ‘Relax’

Maybe the way to a man’s heart isn’t through his stomach, but his nose.

A beer lover’s sense of smell, unlike other senses, takes a unique detour after that first whiff of a beer. When taking a deep inhale of your next brew, consider this: your reaction is first routed through the right (emotional) side of your brain before the left (analytical) side. This is compounded when you drink beers with high levels of hop aromas, which have a significant correlation with creating a relaxed feeling.

3. Battle of the Sexes

Even if you still buy into the idea that women are the “fairer sex” there’s one undeniable thing they’ve certainly got on us men. Women are better at sensing different aspects of beer:

“Women (on average) detect odors at lower concentrations, are more likely to rate smells as more intense and unpleasant, and are better able to identify them by name.”

On a basic level, odor perception between men and women is differentiated thanks to the cellular architecture of brain structures associated with smell. During a test on using the Citra hop, Sierra Nevada found that men would comment on Citra’s smell in a simple means of “tropical fruit,” while women could narrow it down to “catty” and “tomato plant.”

4. Practice Makes Perfect

Whether you’re male or female and want to get better at identifying and understanding hops, plain old research and development is your best bet.

Much like the evolution of our palates as we drink a variety of beers and learn more about them, so too does our ability to detect hop characteristics. Practice smelling hops enough and your brain activity will adjust to help you better remember and ID aspects of hops.

What’s really cool is that even though the sense of smell is routed through the emotional side of your brain, practice (drinking/smelling/etc) begins to even out brain activity to be more analytical than emotional. This may help explain why beer judges can more easily be straight-laced and analytical whereas “non-expert” brains may be more wired to act emotionally to a strongly-hopped beer.

… but don’t take my word for it. Head out to your local bookstore, library or Amazon to check out For the Love of Hops. As a bonus, Hieronymous includes recipes for 15 beloved brews, including Dogfish Head’s Indian Brown Ale, Firestone Walker’s Union Jack and Victory’s Kellerpils. Homebrewers, rejoice!
