To effectively dial in your espresso, follow a systematic approach:

  1. Set a Starting Point: Begin with a standard ratio of coffee to water, typically 1:2 (e.g., 18g coffee to 36g espresso).
  2. Adjust Grind Size:
  • If the shot is too fast (under-extracted), decrease the grind size.
  • If the shot is too slow (over-extracted), increase the grind size.
  1. Monitor Brew Time: Aim for a brew time of 25-30 seconds. Adjust the grind size accordingly to achieve this.
  2. Taste and Analyze: Assess the flavor. Under-extracted shots may taste sour, while over-extracted shots may be bitter.

Fine-Tuning Parameters

After the initial extraction, refine your parameters:

  • Adjust Dose:
  • Increase the dose for a bolder flavor.
  • Decrease the dose for a milder profile.
  • Change Water Temperature:
  • Lower the temperature for lighter, fruitier notes.
  • Raise the temperature for deeper, chocolatey flavors.
  • Experiment with Brew Time: Slightly extend or shorten the brew time based on taste feedback.

Recording Results

Maintain a log of your adjustments and outcomes. A simple table can help track your findings:

Date Dose (g) Grind Size Water Temp (°C) Brew Time (s) Tasting Notes
2023-10-01 18 Fine 93 28 Sour, under-extracted
