Bialetti Moka Express Espresso Maker

This model produces approximately 18 ounces of coffee. Note that in the world of Moka pots, a 'cup' refers to a small 1.5-ounce espresso serving, not a standard 8-ounce coffee mug.

The standard Bialetti Moka Express is made of aluminum and is designed for gas, electric, and ceramic stovetops. It will not work on an induction cooktop unless you use an induction adapter plate.

Aluminum is a porous metal that can absorb the scent and chemical residue of soaps. Rinsing with warm water preserves the seasoned interior, which helps maintain the flavor profile of your coffee over time.

For the best extraction, use a medium-fine grind, similar to the texture of table salt. Avoid using a fine espresso grind, as it can clog the filter and create too much pressure.

The safety valve is a critical pressure-relief mechanism. If the pressure inside the lower chamber exceeds safe levels—often due to an overfilled basket or an incorrect grind—the valve releases excess steam to prevent the unit from over-pressurizing.
