Grind size controls extraction speed: finer extracts faster, coarser slower. Match your grind to your brewer, and adjust one step at a time.
| Grind size | Feels like | Use for |
|---|---|---|
| Extra coarse | Peppercorns | Cold brew, cowboy coffee |
| Coarse | Sea salt | French press, percolator |
| Medium-coarse | Rough sand | Chemex, café solo |
| Medium | Regular sand | Drip machines, siphon |
| Medium-fine | Fine sand | Pour over cones, AeroPress |
| Fine | Table salt / sugar | Espresso, moka pot |
| Extra fine | Powdered sugar | Turkish coffee |
Troubleshooting: bitter cup → grind coarser. Sour or weak cup → grind finer.
