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.
- Immersion
- Brewing method where coffee soaks in water for a set time (Aeropress, Clever, French Press). The opposite of percolation, where water flows through (V60, Chemex).
- 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.
