Bialetti is the world's largest manufacturer of domestic coffee makers. In 1933, Bialetti produced the first Moka Express Stove-top Espresso Maker - a simple yet delicious way to make coffee. Now it is estimated that somewhere in the region of 120 million cups of coffee are made every day using this design of coffee maker. Body made from top quality aluminium alloy Made in Italy Stay-in-cool Bakelite handle and knob Safety Valve Multi cooktop compatible Ergonomically designed Hand wash in warm water only Care and use Instructions on Box 1 cup = approx. 60ml of espresso coffee INFORMATION Your Bialetti coffee maker begins to work when heat is applied to the base causing heat to build up in the lower chamber. (Many believe that the water begins to rise only when the water reaches boiling point however this is not the case). It actually works by heating the air causing it to expand and force the water through the funnel and into the upper chamber. This begins to occur at a temperature of 500C and will end at a temperature of 900C. The end result is a perfect coffee at 700C which, depending on the heat source, will be brewed in approximately 5 10 minutes. Bialetti are able to achieve this temperature by creating the ideal pressure and temperature in the lower chamber. Many imitation units are unable to achieve this ideal temperature and therefore burn the coffee before reaching the upper chamber. The end result is a burnt and bitter coffee. Bialetti uses food grade certified Aluminium which many competitor products around the world simply dont have.
