How to Grind Coffee: Grind Sizes by Brew Method
Getting the grind right is the key to good coffee, and it changes with every brew method. This guide covers the right grind size for each method and how to dial it in by taste.
The short answer
Match the grind to the brew: fine for espresso, medium-fine for AeroPress, medium for pour over, and coarse for French press. Then adjust by taste - if coffee is bitter, grind coarser; if it is weak or sour, grind finer. A burr grinder with good adjustment makes this easy. Grind size controls how fast water extracts, which is why it matters so much.
Grind sizes by brew method
- Espresso: fine, like caster sugar, for fast pressurised extraction.
- AeroPress: medium-fine, around table salt, adjustable by recipe.
- Pour over (V60, Chemex): medium, for an even flow.
- French press: coarse, like sea salt, for clean steeping.
- Cold brew: coarse, for a long, gentle extraction.
These are starting points; tune from there.
Why grind size changes extraction
Finer grounds have more surface area, so water extracts faster; coarser grounds extract slower. Each brew method gives water a certain contact time, so the grind has to match: espresso's seconds need fine, French press's minutes need coarse. Get this balance wrong and the coffee is either over-extracted (bitter) or under-extracted (sour and weak).
Dialling in by taste
Use taste to fine-tune from the starting grind. Bitter, harsh coffee usually means over-extraction - grind coarser (or shorten brew time). Sour, weak, thin coffee usually means under-extraction - grind finer (or lengthen brew time). Change one thing at a time, and a grinder that returns to settings makes it easy to find and keep your sweet spot.
Consistency is half the battle
Even the right average grind tastes poor if it is inconsistent, which is why a burr grinder matters. Uniform particles extract evenly; a blade grinder's mix of dust and boulders extracts unevenly whatever the average. So the path to good grinding is a burr grinder set to the right size for your method, then tuned by taste.
Common mistakes to avoid
- Using one grind for everything instead of matching the method.
- Changing several variables at once when dialling in.
- Grinding too fine for French press (sludge) or too coarse for espresso (sour).
- Relying on a blade grinder, so consistency undermines the grind.
- Not tasting and adjusting from the starting point.

Frequently asked questions
What grind size do I need for different coffee?
Fine for espresso, medium-fine for AeroPress, medium for pour over, and coarse for French press and cold brew. These are starting points - adjust by taste, grinding coarser if bitter and finer if weak or sour.
How do I know if my grind is too fine or too coarse?
Taste tells you: bitter, harsh coffee usually means it is too fine (over-extracted), while weak, sour, thin coffee usually means it is too coarse (under-extracted). Adjust one step at a time toward balance.
Why does grind size matter so much?
Grind size controls how fast water extracts the coffee. Finer grounds extract faster, coarser slower, so the grind must match each method's brew time. The wrong grind gives bitter over-extraction or sour under-extraction.
