Picture this: Turin, Italy, 1884, the year the espresso machine was born. Its creator: Angelo Moriondo, an inventor. A few years pass, and two men become entranced by this glorious creation that brews divine coffee with water and steam.

These two men, named Luigi Bezzerra and Desiderio Pavoni, were compelled to make improvements to the machine's design, including Pavoni's addition of a pressure release valve that prevents baristas from getting burned with the splash of hot coffee.
