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.
Pulse pours
Pouring water in several short rounds instead of one continuous pour. Increases agitation and extraction; controls drawdown time.
