Kalita Wave

How the Kalita Wave works

The Kalita Wave is a flat-bottom dripper with three small holes and a wavy filter that barely touches the wall. The flat bed extracts more evenly than a cone — water travels through the same depth of coffee across the whole area — and the three holes restrict flow, taking much of the responsibility off your pour.

In practice it is the most forgiving pour-over: where the V60 punishes an uneven pour, the Wave delivers consistency. A sweet, round cup with high clarity.

Grind, ratio and temperature

Medium grind — one step coarser than your V60 setting, because the holes already restrict flow — a ratio of 1:15 to 1:17 and water between 92 and 96°C depending on the roast. If the drawdown stalls, the cause is almost always a grind too fine clogging the three holes.

The house recipe

The Standard Kalita Wave uses 22 g for 360 ml (1:16) at 94°C, with short pulsed pours that keep the water level low and steady over the bed. Pulse pouring is the method’s signature: instead of filling the dripper, you top the water up gradually, always at the center, keeping extraction constant from start to finish.

Common mistakes

Pouring onto the filter wall — water escapes through the waves without passing through the coffee (bypass); rinsing the filter with a hard stream and collapsing the waves, which exist precisely to keep the bed off the wall; grinding too fine and clogging the holes; and flooding the dripper with one big pour instead of the short pulses the flat bed wants.
