Physicists unlock another clue to brewing the perfect espresso

This latest work focuses less on the chemical changes that occur during the brewing process and more on the mechanical and physical processes. "To a physicist, brewing coffee is a reactive flow through a complex porous medium that undergoes dynamic reconfiguration—a fascinatingly complex phenomenon," Maciej Lisicki, a physicist at the University of Warsaw in Poland, told Ars.

Just drinking a regular old cup of joe, is where we'd be.
