Kalita Wave
Brew Guide

10 min read Beginner to Intermediate Updated May 2026

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.

Cone Brewer
Hario V60
  • Single large drain hole
  • Cone shape funnels water to centre
  • Very sensitive to pour technique
  • High ceiling: extraordinary when dialled
  • Steep learning curve
  • Best for: advanced home brewers and competition
Flat Bed Brewer
Kalita Wave
  • Three small drain holes
  • Flat bed distributes water evenly
  • More forgiving of pour variation
  • Consistent and sweet across brews
  • 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.

Equipment

Dripper
Kalita Wave 185
Stainless steel or glass. Stainless retains heat better. Glass allows you to watch the brew. Both produce identical results.
Filter
Wave Filter 185
Match filter number to dripper exactly. Crimped wave structure must sit correctly in the dripper for the design to function.
Grinder
Burr Grinder
Medium grind, slightly coarser than V60. The Kalita's slower drain compensates for coarser grind better than a cone brewer.
Kettle
Gooseneck
Recommended but more forgiving than on a V60. Controlled flow still produces better results than a standard kettle.
Scale
0.1g Precision
Weigh dose and water. The Kalita is more consistent than a V60 but still benefits from precise measurements.
Server
Carafe or Cup
The 185 dripper sits on most standard server rims. Preheat before brewing to maintain temperature stability.

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.

Serve

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

1
Rinse the Filter Thoroughly
Place the Kalita Wave filter in the dripper and rinse thoroughly with at least 100ml of hot water. The wave filter has more surface area than a standard flat filter due to its crimped structure, so ensure water reaches all the folds. The rinse serves three purposes: removes paper taste, preheats the dripper and server below, and settles the filter into its correct seated position against the flat base.
Check the filter is seated flat. After rinsing, confirm the base of the filter is sitting flat and even on the dripper floor. A filter that has shifted or folded at the base will restrict the three drain holes unevenly and create an inconsistent drawdown.
2
Grind and Dose
Grind 20g of coffee to a medium grind: slightly coarser than a V60 grind and noticeably finer than a French Press. On most grinders this is 1 to 2 clicks coarser than your V60 setting. Add the grounds to the filter and gently level the bed with a light tap or shake. The Kalita's flat bed means an even, level coffee surface is particularly important: the three drain holes work best when the coffee bed above them is uniform in depth across the entire base.
3
Bloom
Start your timer. Pour 40ml of hot water evenly across the entire coffee bed, starting from the centre and working outward in a slow spiral. The flat bed means the bloom water distributes itself naturally and evenly. You will see the entire bed swell uniformly, unlike a cone brewer where the bloom tends to dome more toward the centre. Allow the bloom to rest for 45 seconds before your first main pour.
Even bloom, even extraction. One of the Kalita's strengths is that the flat bed gives you a visual confirmation of even saturation during the bloom. If the entire surface swells uniformly, your grind is consistent and your pour technique is working. Uneven swelling indicates grind inconsistency or an unlevelled bed.
4
Main Pours
At 0:45, begin your first main pour of 90ml. Pour in slow, even circles from the centre outward. Unlike the V60, you can pour comfortably to within 1 cm of the filter edge without concern. The wave filter walls prevent the paper from collapsing against the dripper wall, so water poured toward the outer edge still passes through the coffee bed rather than bypassing it. Continue with your second pour at 1:20 and final pour at 2:00, maintaining the same slow, even technique throughout.
5
Drawdown
After your final pour, allow the remaining water to drain through completely. The three-hole drain will produce a steady, even drawdown. Watch the surface of the coffee bed as it drains: it should drop evenly across the entire flat surface rather than forming a crater in the centre as a cone brewer does. Total drawdown should complete by 2:45 to 3:30 from the start of your bloom pour.
Even draw, even bed. A healthy Kalita drawdown leaves a uniformly flat, damp coffee bed sitting flush against the flat filter base. If the bed is uneven or shows a visible low point near one of the drain holes, that hole may be partially obstructed or the bed was not level before brewing. Check filter placement on your next brew.
6
Taste and Adjust
The Kalita Wave produces a cup that is typically sweeter and more balanced than a V60 at the same recipe, with slightly more body and less sharp acidity. If the cup is sour or thin, grind finer or raise temperature. If bitter or dry, grind coarser. If the body feels thin despite good flavour, try increasing the dose by 2g before adjusting grind. The Kalita is particularly responsive to dose changes: more coffee in the flat bed creates more resistance and extends extraction naturally.

Variables and Troubleshooting

Problem
Brew Taking Too Long
Grind too fine, filter not seated flat blocking one or more drain holes, or filter collapsed against the dripper wall restricting airflow.
Grind coarser. Re-seat the filter after rinsing to confirm it is flat and the base holes are unobstructed.
Problem
Brew Finishing Too Fast
Grind too coarse for the three-hole drain resistance. Water is passing through faster than the coffee bed can adequately extract.
Grind finer by 2 to 3 clicks. The Kalita's three-hole drain does provide flow resistance but it needs a fine enough grind to extract fully.
Problem
Sour, Underdeveloped Cup
Under-extraction from grind too coarse, temperature too low, or bloom too short for the roast level.
Grind finer, raise temperature by 2°C, extend bloom to 60 seconds especially with light roasts.
Problem
Bitter, Drying Finish
Over-extraction. Grind too fine or temperature too high causing excessive extraction through the slower Kalita drain.
Grind coarser. Lower temperature by 2 to 3°C. The Kalita's slower drain amplifies over-extraction from fine grinds.
Problem
Wrong Filter Used
155 filter used in a 185 dripper or vice versa. Filter does not seat correctly, wave structure collapses, and extraction becomes unpredictable.
Always match filter number to dripper number exactly. Keep filters for different dripper sizes in labelled separate boxes.
Problem
Uneven Drawdown
One or more of the three drain holes is partially blocked by the filter or a coffee ground cluster. Coffee bed was uneven before brewing.
After rinsing, confirm the filter base is flat and all three holes are visible. Level the coffee bed carefully before the bloom.

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 Principle

"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."
