Fast Fixes
- Grind slightly coarser.
- Shorten brew time by 15 to 30 seconds.
- Lower water temperature toward 92 C.
- Use a slightly higher ratio number (for example 1:17 instead of 1:16).
Method-Specific Notes
- Chemex: avoid stalling drawdown and over-pouring late.
- French press: reduce steep time or use coarser grind.
- Moka pot: lower heat and remove from burner earlier.
