Espresso needs a fine grind, a little finer than table salt: it should feel like fine sand and clump slightly when pinched, but not be a powder like flour. The exact setting is different for every grinder and every bag of coffee, so you find it by timing a shot: aim for about 25 to 30 seconds for a 1:2 ratio.
How to dial in, step by step
- Pick a dose and keep it fixed. Use what your basket is made for, often 16 to 18 g for a double.
- Pull a shot and time it. Stop when the espresso weighs about twice the dose, for example 36 g from 18 g.
- Under 20 seconds or sour? Grind finer.
- Over 35 seconds or bitter? Grind coarser.
- Change one thing at a time, in small steps, and purge a little coffee after each grinder change so old grounds don't mix in.
- Taste it. The time is a guide; the right setting is the one that tastes balanced.
Grind size by brew method
| Method | Grind | Feels like |
|---|---|---|
| Turkish | Extra fine | Flour |
| Espresso | Fine | Fine sand, finer than table salt |
| Moka pot | Fine to medium-fine | Table salt |
| Pour-over / drip | Medium | Regular sand |
| French press | Coarse | Sea salt |
Why your grinder matters
Small changes in grind make big changes in espresso, so you need a burr grinder with small steps in its fine range. In our data: Baratza Encore ESP (ZCG495) (40 settings), Fellow Opus 2 Conical Burr Grinder (single-dose), Breville Smart Grinder Pro (BCG820) (60 settings), Eureka Mignon Specialità (flat burrs), Turin DF54 (v4.1) Single Dose Flat Burr Grinder (single-dose).
When to adjust again
- New bag of coffee: always re-dial.
- As beans age: they usually need a slightly finer grind after a couple of weeks.
- Pressurized basket: much more forgiving. A slightly coarser grind works and timing matters less.

Frequently asked questions
What grind size is best for espresso?
A fine grind, slightly finer than table salt, that gives roughly a 1:2 ratio in 25 to 30 seconds. The exact setting varies by grinder and coffee.
Can espresso be ground too fine?
Yes. If the grind is too fine the water can barely pass through, the shot drips slowly and tastes bitter and harsh. Grind a step coarser.
Can I use pre-ground coffee for espresso?
Only with a pressurized (dual-wall) basket. Pre-ground coffee is too coarse and too stale for standard single-wall baskets.
