The Kalita Wave is the pour-over we hand to people who love what a V60 makes but hate how easily it goes wrong. Its flat bed, three tiny drain holes, and ridged filter do the evenness work your pouring technique would otherwise have to do. It is the most forgiving dripper in the pour-over family, and one recipe covers both sizes.
Why Is the Wave So Forgiving?
Kalita, the Japanese filter company that has been making coffee gear since the late 1950s, built the Wave around three design choices that all push in the same direction.
The flat bed. In a cone, the coffee bed is deep in the middle and shallow at the edges, so water finds uneven paths through it. A flat bed keeps depth uniform, which means every particle sees roughly the same water for roughly the same time. Coffee author Scott Rao has argued for years that flat beds extract more evenly than cones, and our flat-bottom vs cone comparison unpacks the geometry.
Three small holes. A V60 has one large hole, so your pour rate effectively sets the drawdown. The Wave's three small holes restrict flow and let the dripper meter itself. Pour a little clumsily and the brew barely notices.
The waved filter. The filter's 20 ridges hold the paper off the dripper wall. That creates an insulating air gap and stops water from slipping down the walls around the coffee, the bypass problem our guide to flow and agitation covers in detail. Water goes through the bed because it has nowhere else to go.
Kalita 155 or 185: Which Size?
- Wave 155: The one-cup size. Happy between 10 and 22 g of coffee, with a sweet spot around 15 g coffee to 250 g water.
- Wave 185: The two-cup size. Happy between 20 and 42 g, with a sweet spot around 30 g to 500 g.
Bed depth is why sizing matters. Drop 15 g into a 185 and the bed sits shallow, drains fast, and underextracts. Push 25 g into a 155 and the bed gets so deep the bottom overextracts while the drawdown crawls. Buy for the brew you make most days, not the occasional crowd. Solo drinkers should take the 155 and resist the bigger-is-safer instinct.
The Base Recipe
The numbers below fit the 185. For the 155, use 15 g coffee and 240 g water: bloom with 30 g, then pour to 135 g at 0:45 and 240 g at 1:30, finishing near 3:00.
- Dose: 25 g coffee
- Water: 400 g at 93°C (199°F), or 88°C (190°F) for dark roasts
- Ratio: 1:16, inside the SCA's Golden Cup range (adjust with the ratio calculator)
- Grind: Medium, similar to V60; start from the middle of our grind size guide
- Total time: 3:30 to 3:45
- Fit the filter, rinse it quickly, dump the rinse water, add coffee, and shake the bed level.
- At 0:00, pour 50 g to bloom. If dry spots survive, give one gentle stir. Wait until 0:45.
- At 0:45, pour to 160 g in slow, coin-sized circles at the center.
- At 1:30, pour to 280 g.
- At 2:15, pour to 400 g.
- The bed should sit flat as it drains, finishing between 3:30 and 3:45.
Sour or weak, grind finer. Bitter or drying, grind coarser. The Wave responds to grind changes cleanly because pour technique barely muddies the signal.
Technique Notes That Actually Matter
- Keep the bed flat. Level the dry grounds before you start and aim for a flat bed after drawdown. A flat finish is visual proof the extraction was even.
- Pour gently, in the center. Keep the kettle low and let the dripper spread the water. High, hard pours dig craters and drive fines downward.
- Stay off the walls. Water aimed at the filter's edge slides around the coffee instead of through it.
- Pulse, do not flood. Several small pours keep the slurry level low and steady, which is what protects that flat bed.
Do Genuine Wave Filters Matter?
More than the dripper itself, honestly. The waves are structural. Generic flat-bottom papers slump against the wall once saturated, closing the air gap and reopening the exact bypass channel the design exists to prevent, so brews stall or race unpredictably. Kalita's papers hold their ridges when wet.
Two practical notes. Rinse briefly, because a heavy rinse can soften and collapse the waves; plenty of brewers skip the rinse entirely and taste no paper. And treat filters as the true running cost of Wave ownership, so stock up when you find them.
Kalita Wave vs V60
| Kalita Wave | Hario V60 | |
|---|---|---|
| Bed shape | Flat, three small holes | Cone, one large hole |
| Who controls flow | Mostly the dripper | Mostly your pour |
| Cup character | Round, sweet, even | Bright, delicate, transparent |
| Skill ceiling | Lower, tight consistency | Higher peaks, more misses |
| Bad-day cup | Still good | Can be rough |
The V60's ceiling is real. With excellent technique, a great grinder, and a delicate light roast, it reaches a transparency the Wave does not quite match. Averaged across a real week of mornings, though, most people drink better coffee from the Wave. Our V60 guide makes the opposite case if you want to hear it.
Steel, Ceramic, or Glass?
- Steel is our default pick: nearly indestructible, light enough to travel, and its thin wall steals very little heat from the brew.
- Ceramic looks great on a shelf but is a big cold mass. Preheat it thoroughly with hot water or it will pull several degrees out of your slurry.
- Glass sits in the middle, lovely to watch and the easiest to break. Kalita also makes a copper version, which is gorgeous and unnecessary.
The Bottom Line
The Kalita Wave is the pour-over for people who want excellent coffee more often than they want a project. It trades the V60's highest highs for a floor so high that a rushed Tuesday brew still tastes like care went into it. If the ritual and the ceiling are your joy, buy a V60 and enjoy the practice. Everyone else should buy the Wave, in the size that matches their daily cup, and spend the saved attention on better beans.
