Taste, then fix
If it tastes wrong
| It tastes | Why | Do this on the Sette 270 |
|---|---|---|
| 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 Baratza Sette 270, 6E 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.
