A classic of twentieth century industrial design, the Bialetti stovetop espresso pot can be found in 90% of Italian homes. With the invention of the Bialetti in the 1930s, espresso – long a staple of Italian cafés and bars – became available for home consumption. As the cold water in the lower chamber heats, the pressure from its boiling forces the water up through the coffee grounds. In just a few minutes, espresso emerges from the spout into the upper chamber as the pot hisses and gurgles. Remove the pot from the heat and let it stand until the lower chamber is releasing only steam. The Bialetti two-part cast aluminum espresso pot has long set the standard for stovetop espresso makers. The lower water tank holds a metal filter and features a safety valve. The upper tank fills with perfectly brewed coffee. Now Italy’s favorite pot can go to work in your kitchen, making delicious espresso on gas or electric stovetops.
