Kalita Wave Dripper - Consistent Flat-Bottom Pour-Over

Kalita Wave 185 Glass Dripper – A Forgiving Flat-Bottom Pour-Over Brewer

The Kalita Wave 185 Glass Dripper is a manual pour-over brewer built around a flat-bottom design, three drainage holes and Kalita's distinctive Wave 185 paper filters.

Rather than using the cone-shaped brewing bed found in many pour-over drippers, the Wave creates a relatively flat bed of coffee. Combined with its three-hole base and pleated filters, this helps distribute water across the grounds and makes the brewer relatively approachable when you're learning pour-over.

The 185 is the larger Wave format, designed for approximately 2–4 cups. This particular version combines a heat-resistant glass brewing chamber with a polypropylene holder.

Why Consider the Kalita Wave 185?

The Wave's main attraction is its approach to controlling water flow and extraction.

Kalita combines a flat-bottom brewing bed with three drainage holes and specially shaped paper filters. The filters have 20 waves around their sides, reducing the amount of contact between the paper and the brewer.

Kalita says this arrangement helps water move through the coffee without accumulating unevenly inside the filter.

For the person brewing the coffee, the practical benefit is a pour-over method that's designed to encourage relatively even saturation without requiring you to direct every pour towards the walls of a cone.

Key Features

• Flat-bottom brewing bed – Helps water spread across the coffee rather than concentrating everything towards a single point.
• Three drainage holes – The characteristic Kalita Wave base controls how brewed coffee leaves the dripper.
• Wave 185 filters – The dedicated paper filters use 20 pleats around their sides.
• Reduced filter contact – The pleated design limits contact between the filter and brewer wall, helping maintain airflow and drainage.
• Heat-resistant glass dripper – The main brewing chamber is glass rather than stainless steel.
• Polypropylene holder – Supports the glass dripper over your mug or server.
• 2–4 cup capacity – The 185 is the larger format within the standard Wave range.
• Dishwasher safe – Kalita lists the glass Wave 185 as suitable for dishwasher cleaning.

How Does the Kalita Wave Work?

Pour-over coffee sounds simple: place coffee in a filter and pour hot water over it.

In practice, the shape of the brewer, filter and coffee bed all affect how that water travels through the grounds.

The Wave approaches this with a flat bottom rather than a pointed cone. Three holes in the base allow the brewed coffee to drain, while the pleated filter helps keep much of the paper away from the walls of the brewer.

The aim is to encourage water to move relatively evenly through the coffee bed.

What Makes the Wave Filter Different?

The Kalita Wave isn't designed around an ordinary cone or basket paper filter.

Its dedicated Wave 185 filters have 20 pleats around their sides. These create the distinctive wave shape and reduce the contact area between the filter and the dripper.

You'll therefore need to factor replacement Wave 185 papers into the ongoing cost of using the brewer.

Generic cone filters aren't a direct substitute.

185 vs 155 – Which Size Do You Need?

Kalita produces more than one Wave size, so it's worth checking before ordering filters or a brewer.

The Wave 185 shown here is intended for approximately 2–4 cups and uses Wave 185 filters.

The smaller Wave 155 is designed around smaller brews and uses its own 155-size papers.

If you usually brew more than a single small cup or want greater flexibility over batch size, the 185 is generally the more versatile option.

What Does Kalita Wave Coffee Taste Like?

The brewer itself doesn't dictate one particular flavour.

Your coffee, grind size, water, ratio, temperature and pouring technique all have a significant influence on the finished cup.

As a paper-filtered method, however, the Wave tends towards a relatively clean cup because the filter removes much of the fine sediment and coffee oils that would pass through a metal-filtered French press.

That can make it particularly useful when you want to explore the differences between coffees and roast profiles.

A Simple Starting Recipe

There are many Kalita Wave recipes, but you don't need to begin with anything complicated.

A useful starting point for a medium-sized brew is:

• Coffee: approximately 20g
• Water: approximately 320g
• Ratio: around 1:16
• Grind: medium as an initial starting point

1. Place a Wave 185 filter into the dripper.
2. Rinse the paper thoroughly with hot water. This also helps preheat the glass brewer and your mug or server.
3. Discard the rinse water.
4. Add your ground coffee and gently level the coffee bed.
5. Add enough water to wet all the grounds and allow the coffee to bloom for approximately 30–45 seconds.
6. Continue adding water gradually in controlled pours.
7. Try to keep the coffee bed evenly saturated rather than pouring heavily against the paper walls.
8. Allow the brewer to drain completely before removing it.

Treat those numbers as a starting point rather than a fixed recipe. Adjust grind, ratio and pouring according to the coffee and the result in your cup.

Do You Need a Gooseneck Kettle?

No – but it can make the process easier.

A gooseneck kettle gives you greater control over where and how quickly water enters the coffee bed.

That becomes particularly useful when you're trying to repeat the same recipe consistently.

One of the Wave's attractions, however, is that its flat-bottom design can be relatively accommodating. You don't need to buy an expensive kettle before you're allowed to start making pour-over coffee.

If you're new to the method, we'd learn the brewer first and add equipment when you understand what problem you want it to solve.

Glass vs Stainless-Steel Kalita Wave

It's worth highlighting this because Kalita produces the Wave 185 in several materials.

The model linked on this page is the glass version.

Its brewing chamber is made from heat-resistant glass with a polypropylene holder.

Kalita also produces stainless-steel and other versions of the Wave. They share the same broad flat-bottom Wave concept, but construction, thermal behaviour, durability and price differ.

The glass model lets you see the coffee and filter while brewing and doesn't require much preheating compared with a substantial metal brewer, but it obviously requires more care when handling and storing.

If break resistance is your priority, a metal version may be worth considering instead.

Who Is the Kalita Wave 185 Best For?

The Wave 185 is particularly worth considering if you:

• want to start exploring pour-over coffee;
• prefer paper-filtered coffee with relatively little sediment;
• want a flat-bottom alternative to cone-shaped drippers;
• usually brew between one larger serving and several smaller cups;
• enjoy experimenting with coffee ratios, grind and pouring;
• want a simple manual brewer without moving parts; or
• prefer a glass brewer to a metal or ceramic alternative.

Who Should Look Elsewhere?

If you want a brewing method that requires almost no pouring technique, an immersion brewer such as a French press or AeroPress may be easier to incorporate into a rushed morning routine.

If you frequently travel with your coffee equipment, glass may not be your preferred material.

You should also remember that the Wave uses its own 185-size filters, so this isn't a paper-free brewing method and you'll need to keep the correct filters available.

And if you normally make only very small single-cup brews, the smaller Wave 155 may be worth comparing before you choose the 185.

Cleaning and Care

The Wave has very little to maintain.

After brewing, remove the paper filter and coffee grounds, rinse the dripper and allow it to dry.

Kalita lists the glass Wave 185 as dishwasher safe, although the glass construction still means it should be handled with reasonable care.

Kalita also recommends warming the dripper before brewing. Rinsing the paper with hot water provides an easy way to preheat the glass at the same time.

Our Take

The Kalita Wave 185 is a good example of a brewer that uses its physical design to make pour-over more manageable.

The combination of a flat coffee bed, three drainage holes and dedicated pleated filters is intended to encourage even flow without demanding an elaborate brewing routine.

That doesn't make technique irrelevant – grind, ratio, pouring and water still matter – but it gives beginners a sensible platform from which to learn.

The main compromises are straightforward: the glass model is breakable and the Wave requires its own proprietary 185 paper filters.

If those aren't concerns and you want a relatively approachable way into manual pour-over brewing, the Wave 185 remains a strong option.
