The 30-second answer
- 💧 Water up to the valve, never above it.
- ☕ Medium-fine ground coffee, no tamping: fill the basket to the brim, level it off, and that's it.
- 🔥 Medium heat, and take it off as soon as it gurgles: that's what prevents bitterness.
- 🧽 No soap and no dishwasher: a rinse with hot water is enough.

The moka pot, or stovetop espresso maker, is in almost every kitchen. Yet many people end up with bitter or "burnt" coffee without knowing why. With the right technique and good coffee, it makes a strong, aromatic cup with no bitterness. Here is the complete method.
How does a moka pot work?
It has three parts: the bottom chamber, for water; the funnel basket, for ground coffee; and the top chamber, where the coffee rises. As it heats, the water is pushed up by steam pressure, passes through the coffee and rises into the top chamber. The pressure is much lower than in an espresso machine: the coffee is strong, but without the crema of a true espresso.
Step by step
- Fill the bottom chamber with water up to the safety valve, no higher. Tip: use water that is already hot, so the coffee spends less time on the heat and is less bitter.
- Fill the basket with ground coffee to the brim, without tamping. Level it with your finger or a spoon and wipe the rim.
- Screw the top on firmly, holding the bottom chamber with a cloth if it's hot.
- Place on medium heat, lid open so you can watch the coffee rise. On gas, the flame should not extend beyond the base.
- Take it off the heat as soon as the coffee starts to gurgle or the stream turns pale and foamy.
- Stir the coffee in the top chamber before serving: the first and last coffee to rise don't taste the same.
The move that changes everything: run the base under cold water right after taking it off the heat. Extraction stops instantly, and the coffee doesn't pick up a burnt taste.
6 mistakes that make coffee bitter
- ❌ Tamping the coffee: the water struggles to pass through, pressure builds and the coffee over-extracts.
- ❌ Filling the water above the valve: it's dangerous and dilutes the coffee.
- ❌ Using too high a heat: the coffee rises too fast and gets too hot.
- ❌ Leaving the pot on the heat after it gurgles: the coffee boils in the top chamber.
- ❌ Using too fine a grind (espresso or Turkish): it clogs the filter.
- ❌ Washing with soap or in the dishwasher: the aluminium gets damaged and the coffee picks up a metallic taste.
Which grind and which coffee?
You need a medium-fine grind, slightly coarser than for espresso. On our coffee pages, simply choose "Ground for Moka Pot". If you have a grinder, see our guide Coffee grinder: which grind for which brewer?.
In terms of taste, the moka pot brings out rounded, chocolatey coffees and gives body to more intense ones. Our favourites: Mexico Altura ORGANIC, Guatemala SHB ORGANIC, Honduras SHB Santa Barbara ORGANIC and, for lovers of bold coffee, Sumatra Gayo Mountain ORGANIC.
OUR FAVOURITE FOR THE MOKA POT
Mexico Altura Organic Coffee
Milk chocolate, hazelnut praline and a delicate acidity: in a moka pot, it becomes rounded, indulgent and free of bitterness. Grown at altitude in Chiapas, organically farmed.
Which size of moka pot?
Sizes are given in "cups", but these are small cups of about 50 ml. So a 3-cup pot makes a little more than one large coffee. Choose the size based on how much you usually drink: a moka pot should always be used full; you can't make a half dose in a large pot. For induction hobs, choose a stainless steel model.
Cleaning
Rinse all three parts with hot water after each use, without soap, and leave them to dry taken apart. Check the rubber gasket and the filter regularly: a hardened gasket lets water leak and should be replaced. A thin brown layer inside the aluminium is normal.
Frequently asked questions
Should you tamp coffee in a moka pot?
No. Fill the basket to the brim and level it without pressing. Tamping stops the water from flowing properly and makes the coffee bitter.
How much coffee goes in a moka pot?
Always fill the basket completely. Allow about 15 to 20 g of coffee for a 3-cup pot.
Why is my moka pot coffee bitter?
Usually: heat too high, pot left on the heat after gurgling, or tamped coffee. Take it off sooner and cool the base.
Can you use a moka pot on induction?
Yes, with an induction-compatible stainless steel model, or with an adapter plate for aluminium models.
What is the best coffee for a moka pot?
A 100% arabica coffee with a medium-fine grind. Chocolatey coffees such as Mexico Altura or Guatemala are excellent in it.
