For those using a brand new moka pot, it is important that you remove any labels that may be stuck on its surface. Thereafter, wash all its removable parts in warm water, and ensure that there is no soap residue left behind. According to Bialetti's website, 2-3 pots of coffee must be made in a brand new pot so as to season it properly.
Additionally, choose a moka pot that will fit the size of your burner. In case of gas stove-top pots, while on the burner, the flame must never be larger than the base of the pot and should not come in contact with the sides of the moka pot. This Buzzle moka pot brewing guide discusses the steps involved in using this macchinetta.
The removable chamber at the bottom holds the water for the coffee. This chamber is called the heating vessel and contains the valve.
Now, gently insert the funnel over the bottom chamber. Make sure that you avoid tamping the espresso-ground coffee into the funnel.
Thereafter, firmly screw the upper portion, that being the main moka pot with the base chamber. This pot is where you will collect the coffee once it is made.
Now, it's time to place the pot on the burner. Wait for a few minutes for the water to boil.
The coffee collector/pot will begin to collect the coffee the moment the water begins to boil. Once the pot is adequately filled, you may remove the moka pot from the burner.
Gently stir the coffee in the pot to help blend the coffee and its flavor. The coffee is prepared and ready to be served.
