Coffee Grind Size Guide

Why Grind Size Matters

Grind size is one of the most important — and most overlooked — variables in brewing great coffee. Too fine and your coffee over-extracts, turning bitter and harsh. Too coarse and it under-extracts, tasting weak and sour. Matching your grind to your brew method is the single fastest way to improve your cup without changing anything else.

The Grind Size Spectrum

Coffee grind sizes range from extra fine (like powdered sugar) to extra coarse (like rough sea salt). Here's how they map to brewing methods:

Extra Fine

Best for: Turkish coffee

Almost powder-like. Coffee is boiled directly in water, so maximum surface area is needed for quick, intense extraction.

Fine

Best for: Espresso

Fine but not powdery — similar to table salt. High pressure forces water through quickly, so a fine grind creates the resistance needed for proper extraction and crema.

Medium-Fine

Best for: Pour-over (V60, Kalita Wave), AeroPress (short brew)

Slightly coarser than espresso. Allows controlled flow rate through a paper filter for a clean, bright cup.

Medium

Best for: Drip coffee makers, siphon, Chemex (with some adjustment)

The most versatile grind — resembles coarse sand. Works well with most automatic drip machines and produces a balanced, approachable cup.

Medium-Coarse

Best for: Chemex, Clever Dripper, café solo

Slightly chunkier than medium. The thicker Chemex filter requires a coarser grind to prevent over-extraction during the longer brew time.

Coarse

Best for: French press, cold brew (short steep)

Resembles rough sea salt. The long steep time of a French press requires a coarse grind to avoid over-extraction and bitterness.

Extra Coarse

Best for: Cold brew (long steep, 12–24 hours), cowboy coffee

The chunkiest grind. Extended cold brew steeping needs maximum coarseness to prevent over-extraction over many hours.

Quick Reference Chart

• Turkish → Extra Fine
• Espresso → Fine
• AeroPress / Pour-over → Medium-Fine
• Drip / Siphon → Medium
• Chemex → Medium-Coarse
• French Press → Coarse
• Cold Brew → Extra Coarse

Burr vs. Blade Grinders

For consistent grind size, always use a burr grinder over a blade grinder. Blade grinders chop beans unevenly, producing a mix of fine dust and large chunks that leads to uneven extraction. A burr grinder crushes beans between two abrasive surfaces for a uniform, consistent grind every time.
