Espresso Calibration Guide

Dialing in the perfect shot, every time
Espresso calibration is the process of adjusting your variables to achieve a balanced, consistent shot. Whether you’re a home brewer or a café barista, mastering this step ensures your coffee tastes exactly as intended.
Espresso calibration (or “dialing in”) is adjusting:
- Grind size
- Dose (coffee weight)
- Yield (espresso output)
- Extraction time
The goal is simple: balance sweetness, acidity, and body.
1. Set Your Dose
Keep your dose consistent (e.g. 18g).
👉 Always weigh your coffee.
2. Adjust Grind Size (Most Important)
- Too fast (under 20 sec) → grind finer
- Too slow (over 35 sec) → grind coarser
👉 Grind size is your primary control.
3. Check Your Yield
- Sour / sharp → increase yield (more extraction)
- Bitter / dry → decrease yield
4. Taste and Adjust
This is key. Use taste, not just numbers
