The Effect of Flow Rate on Espresso Extraction
Investigating how changes in espresso flow rate influence flavour clarity, sweetness, body, and extraction characteristics.
Question
How does controlling flow rate affect espresso flavour when other brewing variables remain consistent?
Hypothesis
Slower flow rates may increase contact time and extraction, potentially increasing sweetness and body, while faster flow rates may preserve brighter acidity and lighter characteristics.

Limitations
- Taste evaluation is subjective.
- Only one coffee may be tested initially.
- Flow rate changes may influence other extraction variables.
Next Steps
Repeat across different roast profiles to determine whether flow rate preference depends on coffee style.
