Agitation helps wet grounds and move fresh water to coffee surfaces. Excessive movement can send fines into filters and create slow, inconsistent drawdown.
What to evaluate
Keep the decision connected to the actual coffee, brewer and serving goal.
- Use the least effective agitation
- Keep kettle height repeatable
- Use gentle bed leveling
- Avoid needless stirring
A repeatable workflow
Use one baseline, then change only what the evidence supports.
- Choose one pour pattern
- Measure additions
- Observe flow
- Adjust agitation after grind is close
Common mistakes
These errors make comparisons unreliable or create avoidable problems.
- Random extra stirs
- Pouring continually on filter walls
- Dramatic kettle height
- Changing pour count and grind together
Repeatable motion matters more than theatrical technique.
