In a small house in State College, a group of college students and recent graduates sip Bolivian black coffee around a dining room table in silence — their eyes fixed on graphs displayed on multiple tablets and smartphones in front of them. After each one takes a sip, they record the flavors they taste on a circular graph via a mobile application they built from scratch.
