Wave filter

The same flat-bottom paper as the Kalita. The pleats keep the paper off the wall and the water drains evenly through the bottom.

Do not crush the pleats when seating it; rinse with a gentle stream so the filter keeps its shape.

Glossary 3
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.
