Dialing in espresso is the process of adjusting your grinder, dose, and brew time to produce a balanced, flavorful shot. It's the single most important skill in home espresso — and the one that separates a good cup from a great one.
The Basic Recipe
Start with these parameters and adjust from there:
- Dose: 18g of ground coffee (for a double basket)
- Yield: 36g of liquid espresso (1:2 ratio)
- Time: 25–30 seconds from pressing the button
- Temperature: 200°F / 93°C (most machines default here)
Step-by-Step Process
- Weigh your dose. Use a scale. 18g is standard for most double baskets (17g for 54mm Breville baskets).
- Pull a shot and time it. If it runs in under 20 seconds, grind finer. Over 35 seconds, grind coarser.
- Weigh the output. You're aiming for roughly double your input weight. 18g in → 36g out.
-
Taste it. This is the real test:
- Sour/acidic? Under-extracted. Grind finer or increase time.
- Bitter/harsh? Over-extracted. Grind coarser or decrease time.
- Sweet, balanced, full-bodied? You're dialed in.
- Change one variable at a time. If you adjust grind AND dose simultaneously, you won't know what fixed (or broke) it.
Common Mistakes
- Not using a scale. Eyeballing dose and yield is the #1 reason for inconsistent shots. A $15 kitchen scale changes everything.
- Stale beans. Coffee peaks 7–21 days after roast. If your bag is older than a month, that's probably the problem.
- Ignoring the puck. A wet, soupy puck usually means channeling — water finding the path of least resistance. Focus on even distribution before tamping.
- Changing too many things at once. Adjust one variable per shot. Patience pays off.
Machine-Specific Tips
Breville (54mm basket): Use 17–18g dose. The Impress system handles tamping, but you still need to dial in grind size. Start at setting 12 and adjust.
E-61 machines (Lelit, ECM, Rocket): 18–20g dose in a 58mm basket. These machines need 20+ minutes warmup. Flush the group before your first shot.
Jura/Delonghi super-automatics: You control strength and volume settings rather than grind directly. Start at medium grind, medium strength, and adjust from there.
When to Re-Dial
You'll need to re-dial whenever you:
- Open a new bag of beans
- Change bean origin or roast level
- Notice shots running significantly faster or slower than usual
- Haven't used the machine in several days (beans degas over time)
🔧 From Our Repair Bench
We see a lot of machines come in for "repair" that actually just need dialing in. Before booking a service appointment, try adjusting your grind size — it solves about 30% of the "my espresso tastes bad" complaints we get. If your machine is making normal sounds and holding pressure, the problem is usually in the cup, not the machine.
