Taste, then fix
If it tastes wrong
| It tastes | Why | Do this on the C40 MK4 |
|---|---|---|
| Bitter, burnt, metallic | Grind too fine or heat too high | Go coarser and pull the pot off the heat as soon as it starts to gurgle |
| Sour and thin | Grind too coarse | Go 2 steps finer and start with pre-boiled water |
| Pot sputters or stalls | Grind too fine or basket tamped | Go coarser and level the basket without pressing |

What you are aiming for
A moka pot wants a grind a little coarser than espresso. Too fine and the pot sputters, over-extracts and tastes burnt.
On the Comandante C40 MK4, 17 clicks is the documented start. If your grounds look much finer or coarser than this, your grinder may be calibrated differently: trust the taste, then the number.
Fix the beans too
Better moka pot starts with fresher beans.
