As a biochemistry major and barista at Beltway Coffee in Abilene, Chandler Graf has a deep passion and appreciation for the integration of science in the art of brewing coffee. Chandler’s TEDxACU talk, filmed at Beltway Coffee and delivered via TED’s live-to-camera video format, shares the science behind choosing the best bag of coffee at the grocery store, making great coffee at home, and even understanding what you’re really ordering the next time you go out for coffee.
