American craft beers keep upping the hops content, making them more and more bitter. But, reports Lizzie Buchen, in New Scientist magazine, humans have a universal dislike for bitter flavors. "Many bitter substances are at best nutritionally useless and at worst downright toxic," Buchen writes, "so we have evolved ways to protect ourselves. Placing a bitter foodstuff on the tongue will trigger a reflex reaction that encourages us to spit it out, or increase saliva flow to wash the taste away. A harmless bitter substance inserted directly into a person's stomach will generally induce nausea."
So why are we running after bitter beers with names like HopSlam?
Psychologists, chemists, neuroscientists and brewers offer Buchen a complex web of reasons, ranging from our craving to be considered connoisseurs to a basic love of carbs ("bitter, hoppy beers often have a higher content of sugar-releasing malts, making for a more intense carbohydrate fix"). And, of course, there's the old "benign masochism" that University of Pennsylvania psychologist Paul Rozin speaks about: pure and simple thrill-seeking, pushing ourselves to the limits of pain, for pure pleasure.
