Less Beans, More Flavor: The Astonishing Physics Trick Transforming Coffee

Penn researchers discovered how to make a richer cup of pour-over coffee using fewer beans by tapping into fluid dynamics. Through creative experiments using transparent particles, lasers, and high-speed cameras, they revealed how specific pouring techniques—like using a gooseneck kettle and pouring from the right height—can maximize flavor extraction. Their findings not only improve coffee [...]
