Coffee Grind Size Guide: How to Dial It In
If your coffee tastes sour, bitter, too fast, or too slow, grind size is often the real issue. This guide shows beginners the right grind ranges for common brew methods and how to adjust them in practice.
Coffee Grind Size Guide
Grind size directly affects extraction speed.
Finer grinds extract more easily; coarser grinds extract less easily.Remember This First
- Too sour, too fast: usually grind finer
- Too bitter, too slow: usually grind coarser
Typical Grind Ranges
| Brew Method | Suggested Grind | | Espresso | Very fine | | V60 pour over | Medium-fine | | Kalita Wave | Medium-fine to medium | | Clever dripper | Medium | | French press | Coarse | | Cold brew | Coarse |
How to Tell If You're Close
- For a 15g / 240g pour over, if drawdown finishes well under 2 minutes, the grind is often too coarse
- If it takes longer than 3:30, it's often too fine
- Thin, sharp cups often point coarser than ideal
- Bitter, heavy cups often point finer than ideal
The Right Way to Adjust
- Change only one small step at a time
- Compare two cups of the same coffee
- Keep ratio and water temperature stable while dialing grind
Common Beginner Mistakes
- Making huge changes all at once
- Reusing the exact same grinder setting for every bean
- Ignoring weather and bean freshness
Even with the same recipe, different origins, processes, and roast levels often need small grind adjustments.
