Taste, then fix
If it tastes wrong
| It tastes | Why | Do this on the C40 MK4 |
|---|---|---|
| Sour, thin, sharp | Under-extracted: grind too coarse or steep too short | Go 2 to 3 steps finer, or add 30 to 60 seconds of steep time |
| Bitter, dry, harsh finish | Over-extracted: grind too fine or steep too long | Go 2 to 3 steps coarser, or cut 30 seconds of steep time |
| Muddy, silty cup | Too many fines for a metal filter | Go coarser and pour gently off the top of the grounds |
| Weak but not sour | Not enough coffee for the water | Tighten the ratio: use 1 to 2 more grams per 250 g of water |
What you are aiming for
A French press uses the coarsest hot-brew grind. It steeps the full four minutes, so a coarse grind keeps it from turning bitter or muddy.
On the Comandante C40 MK4, 30 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 French press starts with fresher beans.
The right grind only gets out what the beans have. A subscription keeps fresh coffee arriving before you run out.
