A visual guide to stovetop espresso
aka Moka Pot, Bialetti, etc
Fill the bottom chamber of the moka pot with water (just off the boil) up to the bottom of the pressure release valve.
Fill the filter basket* to the top with coffee and gently level off without compressing the grounds.
* Note: You cannot 1/2 fill the basket or brew a 1/2 batch
Place the filter basket into the bottom chamber.
Carefully screw the top and the bottom chambers together. Caution: the bottom compartment will be hot so take care.
Place the pot on a stove plate or gas burner with the heat at about 75% or a flame just big enough to cover the base.
Pressure built up by the steam allows the extraction to occur. The water from the bottom chamber will make its way to the top chamber, passing through the coffee grounds.
When you hear a hissing, bubbling sound, the extraction is done, this should take about 2 min.
Remove from the heat source quickly, in order to not over extract the brew.
