“Moka pot” is a stove-top or electric coffee maker that produces coffee by passing boiling water pressurized by steam through ground coffee. It was patented for the first time in Italy by the inventor Luigi De Ponti for Alfonso Bialetti in 1933. Bialetti Industries continues to produce the same model under the name "Moka Express”. Legend suggests that the machine was inspired by early clothes-washing machines which used a heat source to boil a pail of water and cause it to rise up out of a tube, which could be aimed at soiled laundry. In fact the moka pot works in the same way: the water which is below the coffee, when it heats up generates steam. The increases of the pressure in the bottom chamber pushes the water steam up through the coffee granules and then into the top chamber, where it cool down. The coffe is ready to be poured and enjoyed.
