Kalita is best known in specialty coffee for the Kalita Wave, a flat-bottom pour-over dripper designed to make extraction more even and repeatable. This guide explains what Kalita is, how the Wave 155 and Wave 185 work, how Kalita filters affect flow, and when a Kalita Wave is a better choice than a Hario V60.
If you are searching for a simple answer: choose a Kalita Wave when you want a balanced, consistent cup with less technique sensitivity. Choose a V60 when you want higher clarity and more room to shape the cup with pouring technique.
What is Kalita?
Kalita is a Japanese coffee equipment maker associated with hand-drip brewing tools, servers, kettles, filters, and drippers. In the pour-over world, the name is closely tied to the Kalita Wave series: flat-bottom brewers that use wave-shaped paper filters and a small set of drain holes at the base.
The practical appeal is consistency. Cone brewers such as the Hario V60 direct water toward a single point, which can produce excellent clarity but also magnifies pour technique. A Kalita Wave creates a flatter coffee bed, spreading water across a wider surface before it exits through the bottom. That geometry can reduce channeling and make the cup easier to repeat.
For VIHI Design, Kalita matters because the Wave 155 is one of the most popular single-cup flat-bottom brewers, and its paper shape directly affects flow stability. Our research focus is the relationship between dripper geometry, filter shape, airflow, and repeatable extraction.
What Makes the Kalita Wave Different?
The Kalita Wave differs from many pour-over drippers in three important ways: a flat coffee bed, multiple drain holes, and wave-shaped filters.
Flat-bottom coffee bed
A flat bed gives water more room to move evenly through the coffee. This is why many brewers describe the Kalita Wave as round, sweet, balanced, and forgiving. It does not remove the need for good grind size or careful pouring, but it usually gives a wider margin for error than a fast conical brewer.
Three-hole drainage
The Wave’s small drain holes slow and regulate flow compared with an open-bottom cone. When grind size and paper shape are right, this creates a stable drawdown window. When the grind is too fine, or when the filter collapses against the dripper wall, the same design can stall.
Wave-shaped filters
Kalita Wave filters use folded ribs to hold paper away from the dripper wall. Those ribs help preserve airflow and reduce sidewall contact. The tradeoff is that the filters can deform in storage, shipping, rinsing, or handling. When the ribs collapse, flow can become less predictable.
Kalita Wave 155 vs 185
The Kalita Wave 155 and 185 use the same flat-bottom concept but fit different batch sizes. The 155 is the better choice for one cup. The 185 is better for two cups or larger recipes.
| Model | Best For | Typical Dose | Strength | Watch Out For |
|---|---|---|---|---|
| Kalita Wave 155 | Single-cup brewing | 12-18g coffee | Compact bed, efficient extraction, easy daily recipe | More sensitive to filter shape and clogging |
| Kalita Wave 185 | Two cups or larger servings | 20-30g coffee | More brew volume, easier larger pours | Can taste flatter if the dose is too small |
For most home brewers making one cup at a time, the Kalita Wave 155 guide is the most relevant next read. If you are comparing brewers before buying, start with the 155 if your normal recipe is 15g coffee to roughly 230-250g water.
Kalita Wave Brew Recipe
This recipe is a reliable starting point for a Kalita Wave 155. Adjust grind and ratio to taste, but keep the first test simple so you can understand the dripper before changing too many variables.
Kalita Wave 155 starting recipe
- Coffee: 15g
- Water: 240g
- Ratio: 1:16
- Water temperature: 92-95C for light to medium roasts
- Grind: medium to medium-fine filter grind
- Total brew time: about 2:30 to 3:15
- Place the Kalita Wave filter in the dripper and rinse it thoroughly.
- Add 15g coffee and gently level the bed.
- Bloom with 45g water for 30-40 seconds.
- Pour to 140g using a slow spiral, keeping the water level controlled.
- Pour to 240g in one or two steady pours.
- Let the bed drain. The final bed should be mostly flat, not deeply cratered.
If the cup is sharp, thin, or sour, grind a little finer or raise water temperature. If the cup is dry, bitter, or the drawdown is very slow, grind coarser or reduce agitation.
Grind Size, Flow, and Troubleshooting
Kalita brewing is controlled by three overlapping variables: grind size, pour pattern, and filter geometry. Many people focus only on grind size, but the paper shape can be just as important for repeatability.
If your Kalita Wave drains too fast
- Grind slightly finer.
- Use a slower spiral pour to improve saturation.
- Check whether the filter is seated evenly and the coffee bed is level.
If your Kalita Wave stalls
- Grind coarser.
- Use less agitation during the main pours.
- Make sure the filter ribs are not collapsed against the dripper wall.
- Avoid pressing the filter into the brewer during rinsing.
If your Kalita cups taste inconsistent
Use the same dose, kettle height, pour timing, and water temperature for three brews in a row. If the recipe is stable but drawdown still swings widely, inspect the filter. Uneven rib spacing or a distorted paper wall can change bypass and airflow from one brew to the next.
Kalita Wave vs V60
The Kalita Wave and Hario V60 are both excellent pour-over brewers, but they reward different brewing styles.
| Question | Choose Kalita Wave | Choose V60 |
|---|---|---|
| Flavor preference | Balanced, sweet, rounded body | Clear, bright, high-definition acidity |
| Technique sensitivity | More forgiving | More responsive to pour changes |
| Bed shape | Flat-bottom | Conical |
| Best user | Someone who wants repeatability | Someone who enjoys fine control |

Kalita Wave Filters and Paper Geometry
Kalita Wave filters are not just containers for coffee grounds. Their folds create the air gap that helps the brewer work as intended. If the paper ribs collapse, water may contact the wall unevenly, flow can slow, and the same recipe may taste different from one brew to the next.
VIHI Design studies filter paper geometry for Kalita Wave 155 brewing, including how fold angle, rib spacing, and paper deformation influence airflow and drawdown. The goal is not to change the Kalita Wave into another brewer, but to help explain why filter shape matters for repeatable extraction.

V-Fold 155 Paper Former for Kalita Wave 155
If you brew mainly with the smaller Kalita Wave 155, paper shape has a bigger effect than many people expect. A compressed rib, tilted wall, or uneven rinse can change how air moves between the paper and the dripper. The V-Fold 155 paper former is VIHI Design’s dedicated tool for pre-shaping compatible wave-style 155 filter papers before brewing.
V-Fold 155 is not a coffee filter and it does not replace the Kalita brewer. It is a repeatability tool: use it before rinsing, then brew with your normal recipe.

Kalita Setup Checklist
- Use Wave 155 for one cup and Wave 185 for larger batches.
- Use the correct size Kalita Wave filters for your dripper.
- Rinse gently so the filter keeps its ribs and does not collapse.
- Keep your recipe stable before changing grind size.
- Track drawdown time, but judge the final cup by taste first.
Kalita FAQ
Is Kalita better than V60?
Kalita is not universally better than V60. The Kalita Wave is usually better for consistency and balanced body. The V60 is usually better for clarity and fine control.
What is the difference between Kalita Wave 155 and 185?
The Kalita Wave 155 is smaller and best for single-cup brewing. The 185 is larger and better for two cups or bigger recipes.
Why does my Kalita Wave brew stall?
Common causes are too fine a grind, too much agitation, fines migration, or a collapsed paper filter that restricts airflow and drainage.
Can I use V60 filters in a Kalita Wave?
It is not recommended. Kalita Wave brewers are designed for wave-shaped flat-bottom filters. Cone filters change the geometry and can affect flow.
What grind size should I use for Kalita Wave?
Start around medium to medium-fine. If the cup tastes sour or thin, go finer. If it tastes bitter, dry, or drains slowly, go coarser.
