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.
- Swirl
- A gentle circular motion of the dripper. Levels the coffee bed and releases fines stuck on the walls, improving extraction uniformity.
- 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.
