Glossary3
- Bloom
- Pre-infusion. A small water dose over the grounds (usually 2x the coffee weight) that releases CO2 from fresh coffee. Without it, extraction gets uneven.
- Agitation
- Any action that disturbs the coffee bed (vigorous pour, swirl, stir). More agitation means more extraction. Use sparingly.
- Drawdown
- The time between the final pour and the end of drainage. Too long suggests grind too fine or a clogged bed; too short, grind too coarse.
