What Causes Coffee Too Bitter?
Lavazza A Modo Mio machines use proprietary capsules and compact brewing systems.
- Maintenance neglect: Irregular descaling and cleaning are the top causes.

Step-by-Step Fix
Follow these steps specifically for Lavazza machines:
- Decrease grind size on the Lavazza. Over-extraction causes bitterness.
- Clean the brew group. Old coffee oil residue makes coffee taste bitter.
- Verify water temperature. Lavazza machines above 96°C over-extract.
- Use filtered water. Hard water minerals cause bitter off-flavors.
