Kalita Wave
Brew Guide
The Kalita Wave is the pour over brewer that forgives where the V60 punishes. Its flat-bed design, wavy filter walls, and three-hole drain produce a more even, predictable extraction that rewards consistency rather than demanding perfection with every pour.
Designed by Japanese manufacturer Kalita, the Wave series uses a flat-bottomed stainless steel or glass dripper combined with a distinctive crimped filter that keeps the paper away from the dripper walls. This design slows drainage slightly compared to the V60 and creates a more uniform water saturation across the coffee bed. The result is a sweet, balanced, full-flavoured cup that sits between the precision-dependent V60 and the body-forward French Press.
The Kalita is widely used in specialty cafés as a service brewer precisely because it delivers consistent quality across multiple cups without the pour technique sensitivity of the V60. For home brewers, it is an excellent step up from the French Press or an accessible alternative to the V60 for those who want clarity and sweetness without the steep learning curve.
Flat Bed vs Cone: Why It Matters
The fundamental design difference between the Kalita Wave and the Hario V60 is the shape of the brew bed. The V60's conical shape means water naturally converges toward the single centre drain hole, creating a faster, less forgiving flow path. The Kalita's flat bed distributes water evenly across the entire coffee surface before it drains through three small holes spaced evenly at the base.
Three small holes rather than one large one gives the Kalita a built-in flow resistance that the V60 lacks. This resistance acts as a buffer: even if your pour is slightly uneven or your grind is marginally off, the flat bed and three-hole drain tend to self-correct more than a cone brewer would. The wavy filter paper adds another layer of buffering by creating an air gap between the filter and the dripper walls, preventing the paper from collapsing against the metal and restricting airflow.

- Accessible for most skill levels
- Best for: home brewing and café service
Kalita Wave Filter Sizes
Kalita Wave drippers and their corresponding filters come in three main sizes: 155, 185, and 185 large. The number refers to the diameter of the flat base in millimetres. Each size has its own matching filter, and filters are not interchangeable between sizes. Using the wrong filter size collapses the wavy structure and defeats the design entirely.
| Filter Size | Dripper | Dose Range | Servings and Best Use |
|---|---|---|---|
| 155 Small | Kalita Wave 155 | 10 to 20g | Single cup. Ideal for dialling in a new coffee or solo brewing. Best for pour-over bars and home single-serve setups. |
| 185 Standard | Kalita Wave 185 | 20 to 35g | One to two cups. The most commonly used size in cafés and specialty shops. The recommended starting point for most brewers. |
| 185 Large | Kalita Wave 185 (large) | 30 to 50g | Two to four cups. Batch brewing for small groups or café service. Requires a larger server or carafe below. |
Kalita Wave filters are available in two materials: paper and stainless steel mesh. Paper filters produce the cleaner, brighter cup by removing oils and fine particles. Metal filters allow more oils through and produce a heavier-bodied brew closer to a French Press in texture but with pour over clarity. For most applications, paper filters are preferred. When purchasing paper filters, ensure you are buying the correct numbered size for your dripper: a 155 filter will not function correctly in a 185 dripper and vice versa.
Paper Kalita filters are also available in natural (unbleached) and bleached white versions. As with Chemex, bleached filters require less aggressive rinsing and produce a marginally cleaner cup. Both work well. Always rinse before use regardless of which type you choose.

Starting Ratios
The Kalita Wave uses a 1:15 to 1:16 ratio. The recipe below is for a 185 dripper producing a generous single serving or a light two-cup brew. The Kalita's flat bed and slower drain mean it performs well at slightly coarser grind settings than the V60 at the same ratio.
Brew time target on the Kalita is slightly longer than the V60: 2 minutes 45 seconds to 3 minutes 30 seconds for a 20g brew. If your drawdown completes faster than 2:30, grind finer by a few clicks. If it exceeds 3:45, grind coarser. Unlike the V60 where a 20-second variance is significant, the Kalita tolerates a slightly wider brew time window due to the buffering effect of the flat bed and three-hole drain.
Water temperature follows roast profile: light roasts at 92 to 94°C, medium roasts at 89 to 92°C, dark roasts at 86 to 90°C. The Kalita's slightly slower extraction means you can typically brew light roasts at a degree or two lower temperature than you would on a V60 and still achieve full extraction.
The Pour Timeline
The Kalita Wave works well with both pulsed and continuous pour techniques. The recipe below uses a four-pour structure which gives you maximum control over the extraction and takes advantage of the flat bed's even saturation properties. Once you are comfortable with this, try a continuous pour from 0:45 onward for a simpler, faster workflow.
The key difference in Kalita pour technique versus V60: on the Kalita, you can pour more toward the outer edges of the bed without significant risk of channelling. The flat bed distributes water laterally before it drains, so a slightly wider pour pattern works well and ensures the full coffee bed is evenly saturated. On a V60, pouring toward the edges carries more risk of hitting the filter directly. On the Kalita, this concern is significantly reduced.
Step by Step
Variables and Troubleshooting
The Brewer That
Rewards Consistency
I recommend the Kalita Wave to anyone who wants the quality of a specialty pour over without spending months learning the V60. The flat bed is genuinely forgiving in a way that the cone is not. If your pour is slightly off on a V60, the cup tells you immediately and harshly. The Kalita absorbs minor pour variation without punishing you in the cup. For café service especially, that consistency across multiple brews across a long shift is exactly what you need.
The one thing I always emphasise when training baristas on the Kalita: check the filter seat every single brew. The wave filter looks secure after rinsing but it is easy for one edge to lift slightly or for the base to not sit completely flat. When that happens, one or two of the three drain holes get partially covered, and your drawdown becomes uneven without you realising why. Make it a habit to press the filter base gently flat with your fingertip after rinsing and before adding coffee. Ten seconds that saves you a confused cup.
On filter choice: if you can get the bleached Kalita paper filters, use those. The natural filters work fine but require a more thorough rinse. In a café setting where you are brewing continuously, the bleached filters are more consistent. For home use, either is fine as long as you rinse properly.
"The Kalita does not reward brilliance. It rewards consistency. Same grind, same dose, same pour, every time. That is exactly why it belongs in every serious café."
