Place the Wave filter in the dripper and rinse thoroughly with hot water. The filter should sit flat with crimps intact. Discard rinse water.

Avoid pushing the filter against the dripper walls — the crimps should maintain an air gap for even drainage.

Add 18g of medium-fine ground coffee. Shake gently to level the bed.

Start timer. Bloom with 40g of 92°C water, pouring from the center outward. Wait 40 seconds.

At 0:40, pour in slow concentric circles to 150g. Stay in the center, avoiding pouring directly on the filter walls.

Keeping pours centered prevents water from channeling down the sides and bypassing the coffee bed.

At 1:15, continue pouring in pulses to 300g total. Add 50g at a time, letting the water draw down slightly between each pulse.

Let the bed draw down completely. Total brew time should be 3:00-3:30. The flat bed should look even with no high-and-dry grounds.
