What is the Kalita Wave 185?
The flat-bottom dripper, and the main alternative to the cone everybody starts with.
Kalita publishes a patented wave design credited with reducing contact between the brewing space and the filter for a more balanced extraction, polished stainless steel construction made in Japan, three drainage holes, dishwasher safety, and a capacity of up to four cups. Kalita also states the steel heats faster than ceramic or glass and holds temperature through the brew. It measures 4.5 by 4.8 by 2.5 inches.
Why a flat bed forgives what a cone punishes
A cone concentrates the coffee at the bottom. A flat bed does not, and that changes the difficulty.
In a V60, the bed is deep at the point and shallow at the rim, so water takes very different paths depending on where you pour it. Pour off-centre and part of the bed is over-extracted while part is barely wetted. This is why a V60 rewards a slow, circular, controlled pour and why it can taste different every morning.
A flat bottom spreads the same dose into an even layer. Every part of the bed is the same depth, so the water passes through in a more uniform time regardless of how neatly you poured. Combined with three small holes rather than one large one, which caps how fast the water can leave, the Wave is dramatically more consistent in an untrained hand.
The cost is ceiling rather than floor. A cone in expert hands can be steered by pour technique in ways a flat bed cannot. The Wave gives up some of that control in exchange for repeatability, and for most people that is the right trade.
The wave filter is the running cost nobody mentions
The pleats are the mechanism, and only Kalita makes them.
The filter's corrugations are not decoration. They hold the paper off the steel wall, which is the job ribs do in a ribbed cone, and they are why this dripper has no ribs at all. The filter is a structural part of the brewer.
That means wave filters fit Kalita drippers and nothing else, and no reusable metal version replicates the pleats. Where a Melitta #2 paper is sold in every supermarket for pennies by a dozen makers, a wave filter is a single-source consumable you will be buying for as long as you own the brewer. Over years that is real money and it is worth knowing before, not after.
Kalita Wave vs Fellow Stagg [X]
The two steel flat bottoms, and they differ on what comes in the box.
The Fellow Stagg [X] is sold as a set with a double-walled carafe and a ratio aid, so it is a complete brewing kit rather than a dripper.
The Wave is the dripper alone, cheaper, made in Japan, dishwasher safe, and the one you will actually find in competition cafes. Both use a proprietary paper. If you already own a carafe and a scale, the Wave. If you are starting from nothing, the Stagg set costs less than buying the pieces.
Is the Kalita Wave 185 worth it?
Worth it, and it is the dripper to buy if your pour over is inconsistent.
It costs a little more than a plastic cone and rather less than most ceramic ones, and it solves the single most common complaint about pour over, which is that it tastes different every day.
Kalita publishes no hole diameter, no weight and no warranty term on this listing, and no reusable filter exists. The 185 is the larger of the two sizes; the 155 is the single-cup version and is a different product.
Who should buy it (and who should not)
Buy it if you want good coffee without learning to pour like a barista.
It suits somebody brewing two to four cups, who owns a scale and a gooseneck kettle, and who has grown tired of a V60 that behaves differently every morning.
Do not buy it if you want to experiment with pour technique, because the flat bed deliberately mutes it. And do not buy it if a single-source filter you can only get online is a problem, in which case a Melitta or a V60 is the sensible answer.
Frequently Asked Questions
Why does the Kalita Wave have three holes?
Three small holes restrict the flow more predictably than one large one, so the brew time is less dependent on how you pour.
Can you use other filters in a Kalita Wave?
No. The wave filter's pleats hold the paper off the wall and no other filter does that. There is no reusable version.
Is the Kalita Wave better than a V60?
More consistent, less controllable. A flat bed brews evenly whatever your pour does; a cone rewards technique and punishes its absence.
What size is the 185?
The larger Kalita, up to four cups. The 155 is the single-cup size.
Is it dishwasher safe?
Yes, per the maker.
