Grind Details

Coffee grind size affects extraction and flavor.

Grind sizes by brew method:

Brew Method Grind Setting Microns Description
Turkish coffee Extra fine 100-200 Powder-like
Espresso Fine 200-400 Table salt
Moka pot Fine-medium 400-500 Fine sand
AeroPress Medium-fine 500-700 Sand
Pour over (V60) Medium 600-850 Sea salt
Drip coffee Medium 700-1000 Rough sand
Chemex Medium-coarse 800-1100 Coarse sand
French press Coarse 1000-1200 Kosher salt

General rule:

  • Finer grind = faster extraction = stronger, more bitter.
  • Coarser grind = slower extraction = lighter, less bitter.
  • Shorter brew time needs finer grind.
