Coffee, Expresso or Cappuccino

This is a guide to using a stovetop moka pot, the classic Italian coffee maker that brews a concentrated, espresso-style beverage right on your burner. No expensive machine needed, just cold water, finely ground coffee, and a few minutes of heat.

The reducer insert is the key to getting the right strength at different volumes. Flip it one way for three cups, the other way for six, or remove it entirely for a full nine-cup brew. Fill the basket right to the rim with coffee grounds and make sure the rim and o-ring are clean before sealing. Even a few stray grounds can prevent a proper seal and cause weak, sputtery extraction.

Listen to the pot. The coffee starts dripping out dark and slow, then builds to a steady stream as pressure increases. When the flow stops and you hear a gurgling, hissing sound, the brewing is done. Pull it off the heat immediately. Leaving it on the burner scorches the coffee and gives it a bitter, burnt taste.

For cappuccino, close the valve after brewing and let steam pressure build, then open it to froth milk in a cup. The steam won’t be as powerful as a commercial machine, but it produces a respectable foam.

Chef Tips

• Always start with cold water. Hot water heats the coffee grounds before pressure builds, leading to over-extraction and bitterness.
• Use a medium-fine grind, not true espresso fine. Too fine clogs the basket and stalls the brew. Too coarse makes it watery.
• Don’t tamp the grounds. Just level them off. Packing them tight restricts water flow and can damage the safety valve.
• Clean the o-ring regularly. Old coffee oils build up and eventually cause leaks and off flavors.
