Moka pot or Moka Express is a type of coffee maker machine that produces coffee beverages by passing very hot and pressurized water through ground coffee. This type of pot was first registered in 1933 by Luigi de Ponti and exclusively for the Italian company Alfonso Bialetti. Bialetti Industries produced and marketed this type of coffee maker under the name of Moka Espresso.
There’s a lot going on inside the Moka Pot to finally get you a cup of delicious coffee. The steps are as follows:
1: When the water boils at the bottom, the hot air expands and creates pressure. This pressure causes the boiling water to move in to the tunnel coffee powder chamber.
2: After the boiling water moves upwards, the coffee powder in the chamber is compressed and condensed towards the filter.
3: By absorbing boiling water, the coffee also expands and creates more pressure between the two chambers.
4: When the coffee is completely wet and saturated, the water passes through a metal filter and goes to the upper tunnel.
5: When the last drops of boiling water go to the upper chamber, you will hear a familiar and exciting sound. A sign that says coffee is ready to serve.
If you are not strict, you can make several other types of coffee with Moka pot. Although there are many coffee maker machines today such as French press coffee maker and siphon coffee maker, the Italians still use this machine to make espresso.
