Flat-bottom drippers spread coffee across a wider bed and can be forgiving when pours are even. Their flow differs from cone brewers.
What to evaluate
Keep the decision connected to the actual coffee, brewer and serving goal.
- Use the designed filter
- Keep the bed level
- Do not crush wave filters
- Match pour rate to drainage
A repeatable workflow
Use one baseline, then change only what the evidence supports.
- Start medium-fine
- Bloom gently
- Use centered pours
- Record drawdown
Common mistakes
These errors make comparisons unreliable or create avoidable problems.
- Collapsing filter waves
- Copying cone settings
- Overfilling a small brewer
- Using cone visual cues
Geometry changes flow, so recipe transfer needs a new baseline.
