Taste, then fix
If it tastes wrong
| It tastes | Why | Do this on the Barista Express (built-in grinder) |
|---|---|---|
| Sour, salty, fast (under 22 s) | Under-extracted: grind too coarse | Go 1 to 2 steps finer and pull again |
| Bitter, ashy, slow (over 35 s) | Over-extracted: grind too fine | Go 1 to 2 steps coarser |
| Sour and bitter at once | Channeling: water found a crack in the puck | Keep the grind; stir the grounds (WDT), tamp level, check the dose fits the basket |
| Right time, still sour | Ratio too short for the roast | Pull a longer shot: go from 1:2 toward 1:2.5 |
| Right time, still bitter | Ratio too long or brew too hot | Pull a shorter shot (toward 1:1.8) or drop the temperature 1 to 2 C |
What you are aiming for
Espresso needs the finest grind of any method. Small moves matter: one step on most grinders shifts the shot by several seconds.
On the Breville Barista Express (built-in grinder), 5 is the documented start. If your grounds look much finer or coarser than this, your grinder may be calibrated differently: trust the taste, then the number.
Fix the beans too
The grind is set. Now the beans.
Espresso is where stale beans show first. Coffee 7 to 30 days off roast holds a setting; old coffee drifts every day.
