Moka pot guide: adjusting for light, medium and dark

5 min read

Fill the base with hot water just below the valve, fill the basket level without tamping, and brew on medium-low heat with the lid open. Grind finer for light roasts (about 66 clicks on a K-Ultra) and coarser for dark roasts (about 72). Pull it off the heat as soon as it starts to sputter.

A moka pot pushes water up through the coffee using steam pressure. It is not espresso, but it gives a bold, thick cup that is great on its own, with hot milk, or as a base for iced drinks. Most burnt-tasting moka coffee comes from too much heat, not bad beans.

Grind and heat by roast

Roast	K-Ultra clicks	Starting water	Heat
Light	66	Just off the boil	Medium
Medium	69	Hot from the kettle	Medium-low
Dark	72	Hot, not boiling	Low

Method

Boil water and pour it into the base up to just below the safety valve.
Fill the basket with ground coffee until level. Tap to settle, sweep off the excess, and do not tamp.
Hold the hot base with a cloth and screw on the top firmly.
Place on medium-low heat with the lid open. On a gas stove, keep the flame smaller than the base.
When coffee starts flowing, lower the heat. You want a steady honey-coloured stream.
As soon as it turns pale and starts to sputter, take it off and cool the base under a tap to stop extraction.
Stir the coffee in the top chamber before pouring, since the first and last parts taste very different.

Tip: Starting with hot water means the coffee spends less time heating on the stove. That alone removes a lot of the metallic, burnt taste.

Troubleshooting

Symptom	Likely cause	Fix
Burnt, metallic	Heat too high or cold start	Start with hot water, use lower heat, cool the base early
Sour and thin	Grind too coarse for a light roast	Grind 2–3 clicks finer
Coffee spurts or will not flow	Grind too fine or coffee tamped	Go coarser and never tamp
Leaks from the middle	Worn gasket or grounds on the rim	Wipe the rim, replace the gasket
Bitter with dark roasts	Over-extraction	Coarser grind, lower heat
