Glossary2
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.
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.
