The grind size for espresso is fine, similar to table salt or slightly finer, so that pressurised water takes about 25 to 30 seconds to pull a shot. If the shot runs too fast and tastes sour, grind finer; if it runs too slow and tastes bitter, grind coarser. Espresso is the most grind-sensitive brewing method, so a good burr grinder and small adjustments are key.

Quick Answer

Espresso needs a fine grind, around the texture of table salt. Aim for a 25 to 30 second shot. Too fast and sour means grind finer; too slow and bitter means grind coarser. Adjust in small steps.

Short Answer

Grind espresso fine, near table salt or a touch finer. Use the shot time as your guide: about 25 to 30 seconds for a balanced shot. Dial the grind in small increments until the time and taste are right.

How Fine Is Espresso Grind?

Espresso grind is fine but not powdery. A useful reference is table salt: drip coffee is closer to coarse sand, French press is like coarse sea salt, and espresso is finer than both. Because the grind is so fine, only a burr grinder with espresso range can do it consistently.

Brew method Grind Reference
French press Coarse Coarse sea salt
Drip Medium Coarse sand
Pour-over Medium-fine Fine sand
Espresso Fine Table salt

Key Takeaway: Use shot time, not just looks, to judge grind. A 25 to 30 second shot from your dose usually means the grind is dialled in.

Dialling In Your Espresso Grind

  1. Start near the middle of your grinder’s espresso range.
  2. Pull a shot and time it from when the pump starts.
  3. If it runs under about 20 seconds and tastes sour, grind finer.
  4. If it runs over about 35 seconds and tastes bitter, grind coarser.
  5. Adjust one small step at a time and re-taste.

Why Grinder Quality Matters for Espresso

Espresso amplifies any unevenness in the grind, so a precise burr grinder is essential; a blade grinder cannot make espresso. If you are buying for espresso, choose an espresso-capable grinder; see our best burr grinders and best coffee grinders.

Common Espresso Grind Problems

  • Shot gushes, sour: grind too coarse, grind finer.
  • Shot drips, bitter: grind too fine, grind coarser.
  • Uneven flow (channelling): distribute and tamp evenly.
  • Inconsistent shots: often a weak grinder; upgrade to a burr.

FAQ

What does espresso grind look like?

Espresso grind is fine, around the texture of table salt or slightly finer. It is finer than drip or French press grind and needs a burr grinder to produce consistently.

How do I know if my espresso grind is right?

Use the shot time. A balanced shot from your dose usually takes about 25 to 30 seconds. Too fast and sour means grind finer; too slow and bitter means grind coarser.

Can you make espresso with pre-ground coffee?

You can use pre-ground espresso coffee, but you lose freshness and the ability to adjust the grind. For the best shots, grind fresh with a burr grinder.

Bottom Line

Grind espresso fine, around table salt, and use a 25 to 30 second shot as your target, adjusting in small steps. A precise burr grinder makes this possible. To choose one, see our best burr grinders, and for machines, our best espresso machines.
