How to use a moka pot without burning the coffee

The moka pot, the eight-sided aluminium pot that Bialetti made famous, sits on the stove in millions of kitchens, above all in Italy. It makes a small, strong, intense coffee without an espresso machine. It is not quite espresso: a moka pot brews at around 1 to 2 bar of steam pressure, an espresso machine at about 9 bar. But done well, it is concentrated, sweet and perfect on its own or with hot milk. Done badly, it tastes burnt and metallic. The difference is almost always heat.

How a moka pot works

A moka pot has three parts: the bottom chamber for water, a funnel-shaped basket for the coffee and the top chamber where the coffee collects. As the water heats, steam pressure pushes it up through the coffee and into the top. That is why the water level, the grind and the heat all matter: they decide how fast the water passes through the coffee.

What you need

• A moka pot in the size you drink. The "cup" sizes refer to small espresso cups of about 50 ml, so a 3-cup pot makes about 130 to 150 ml. Pots are made for one size; do not fill a large pot halfway. Browse espresso makers or the Bialetti pots in the catalog.
• Coffee ground fine, but a little coarser than for espresso machines (more in the grind size chart). Ground coffee labelled for moka pots, or espresso beans you grind yourself, both work.
• A kettle. Starting with hot water is the most important trick on this page.

How to make moka pot coffee, step by step

1. Fill the bottom with hot water, just below the safety valve. Never cover the valve. Hot water (just off the boil) shortens the time the pot sits on the flame, so the coffee does not cook and taste metallic.
2. Fill the basket with ground coffee until it is level with the rim. Tap it to settle, wipe the edge clean. Do not press it down: a tamped basket can block the flow and build up too much pressure.
3. Screw the pot together with a cloth, because the bottom is hot. Make it tight, but do not force it.
4. Medium-low heat, lid open. On a gas stove, the flame should not reach past the bottom of the pot.
5. Watch the coffee rise. It should flow in a steady, honey-coloured stream. If it spurts, the heat is too high.
6. Take it off as it starts to gurgle and turns pale, before it sputters. Cool the base under cold water or with a wet towel to stop the brewing at once.
7. Stir and serve. The first coffee to come out is the strongest; stirring in the top chamber evens it out.

Why does my moka pot coffee taste bitter or burnt?

• Too much heat for too long. Start with hot water and keep the flame low.
• Leaving it on until it sputters. The last part is steam forced through spent coffee. Take it off earlier.
• Too fine a grind or a tamped basket. The water struggles through and over-extracts.
• Very dark beans. A moka pot concentrates roast flavours. A medium or medium-dark roast is often sweeter.
• A dirty or new pot. Old coffee oils taste rancid; a brand-new aluminium pot often tastes metallic for the first few brews. Make two or three pots and pour them away.

Which coffee for a moka pot?

Italian-style blends are the classic choice, and many contain some robusta for body and crema. If you like chocolate and caramel, look at medium-dark roasts from Brazil or blends labelled for moka. If you like a brighter cup, a medium-roasted single origin from Colombia or Ethiopia can be lovely in a moka pot, as long as you keep the heat gentle. Many Italian coffees in the catalog are roasted with the moka pot in mind.

Cleaning and care

Rinse all parts with hot water after each use and let them dry apart. Most traditional aluminium pots should not go in the dishwasher, and soap is best avoided on aluminium; check the maker's instructions. Stainless steel pots are easier to clean and work on induction. Replace the rubber gasket and filter plate when the pot starts to leak at the joint, usually every year or so with daily use.

Quick answers

Is moka pot coffee espresso?

No. It is strong and concentrated, but brewed at far lower pressure, so it has little or no crema and a different texture. It is closer to a very strong filter coffee.

Does a moka pot work on induction?

Only if it is made of magnetic stainless steel, or with an induction adapter plate. Classic aluminium pots do not work on induction.

Can I make a cappuccino with a moka pot?

Yes, moka coffee with frothed milk makes a good home cappuccino. See how to make a cappuccino at home.
