A flat-bottom approach to pour-over
The Kalita Wave 185 Glass Dripper combines a flat-bottom coffee bed, three drainage holes and dedicated pleated Wave 185 paper filters. The reviewed version uses a heat-resistant glass chamber with a polypropylene holder.
This overview is adapted from our existing equipment review, not a hands-on testing report. Specifications and manufacturer explanations below reflect that source. Confirm the exact size, material and current instructions before buying.

Why consider the Wave?
The Wave offers a different geometry from a cone-shaped dripper. Its flat bed, drainage holes and shaped paper are intended to encourage even water movement through the coffee.
That design can appeal as a structured starting point, but it does not make technique irrelevant or guarantee even extraction. Coffee, grind, filter condition, pouring and water all remain important.
Source-listed features
- Glass Wave 185 model with a polypropylene holder.
- Flat-bottom brewing bed and three drainage holes.
- Wave 185 papers with 20 side pleats.
- Source-listed serving range of approximately 2–4 cups.
- Manual paper-filtered percolation.
- Dishwasher suitability listed in the source, subject to exact-model guidance.
The cup rating is not a promise of four large UK mugs. Choose a suitable recipe and receiving vessel, and follow safe fill requirements.
How the filter and base work together
The original review records Kalita's explanation that the pleated filter reduces paper contact with the brewer walls, helping preserve space around the filter. The three holes provide the drainage route beneath a relatively flat coffee bed.
Those are design descriptions, not measured proof that every brew drains evenly or that this model outperforms every cone dripper.
Use the correct Wave 185 papers
This brewer is designed around Wave 185 filters. Ordinary cone or basket papers are not direct substitutes for the intended shape, and smaller Wave 155 papers should not be assumed interchangeable.
Include filter availability and ongoing cost in your buying decision. Check whether the retailer's package includes papers or only the dripper.
185 versus 155
The source identifies the 185 as the larger standard Wave format and the 155 as a smaller-brew option with its own filters. Choose according to your usual recipe rather than cup labels alone.
A larger dripper is not automatically best for every small dose. Compare the intended batch range for the exact model.
A simple starting recipe
Try 20g coffee and 320g water, a 1:16 ratio, with a medium grind as an initial reference. This is a starting recipe, not a tested ideal for every bean.
- Place a compatible Wave 185 filter in the dripper on a stable, suitable mug or server.
- Rinse the paper carefully with hot water, retaining its shape, and discard the rinse water.
- Add the coffee and gently level the bed.
- Wet the grounds evenly and allow approximately 30–45 seconds for the bloom.
- Add the remaining recipe water in controlled pours without overfilling.
- Allow drawdown to finish before removing the dripper carefully.
Follow the manufacturer's operating guidance and handle hot water and glass safely. Change one main recipe variable at a time and use taste to guide adjustments.
What sort of cup should you expect?
Paper filtration retains much fine sediment and some oils that would remain in metal-filtered immersion coffee. That creates a different texture from a cafetière.
The brewer itself does not impose one flavour. Bean choice, roast, water and preparation still shape the result. This overview does not claim tasting results from our own testing.
Do you need a gooseneck kettle?
No. You can start with a conventional kettle. A gooseneck becomes useful when you specifically want more control over flow and where water lands.
Our TIMEMORE Fish Smart overview and Fellow Stagg EKG Pro overview describe different feature sets. Neither is compulsory before you begin learning the Wave.
Glass versus other Wave materials
This article concerns the glass 185, not the stainless-steel or other versions. They share the broad Wave concept, but construction, thermal behaviour, handling and price can differ.
Do not assume identical drainage or preheating requirements across materials. We have not performed comparative thermal, flow or durability tests. Glass needs protection from knocks and careful storage.
Wave versus V60
The V60 Plastic 02 uses a cone-shaped bed and one large opening, while the Wave uses a flat bed and three holes. Both involve active pouring and recipe adjustment.
Choose according to the workflow and equipment you prefer rather than expecting one geometry to guarantee better coffee.
Wave versus Chemex
The Chemex Classic 6-Cup combines brewing and serving in one vessel and uses its own substantial paper filters. The Wave sits on a separate mug or server.
Compare the exact batch size, filter cost, handling and storage needs of each setup.
Who is it for?
Consider the glass Wave 185 if you want to explore flat-bottom pour-over, enjoy paper-filtered coffee and are willing to keep compatible filters available.
If precise pouring is not appealing, an immersion-led option such as the Clever Dripper may better suit your routine. For rough travel or very small doses, compare other materials and sizes.
Cleaning and care
Remove used paper and grounds appropriately, then clean and dry the dripper as instructed. The source records Kalita's dishwasher-safe listing for the glass 185; follow current guidance for the complete model and its holder.
The original review also records a recommendation to preheat. Rinsing the filter can form part of that routine. Treat heat-resistant glass as breakable, inspect it for damage and avoid knocks or temperature shocks.
Our take
The glass Wave 185 is a distinct route into pour-over: a flat bed, three drainage holes and pleated filters rather than a pointed cone. It gives you a useful platform for learning without eliminating the need for a repeatable recipe.
Its practical buying checks are the exact material, appropriate batch size and continuing supply of 185 papers. Choose it because that setup suits you, not an untested promise of automatic consistency.
