How to Brew with KalitaWave: A Flat-Bottom Pour-Over Guide

If you've tried brewing pour-over coffee but found your results inconsistent—sometimes under-extracted, sometimes bitter—you're not alone. Many home brewers struggle to get even extraction across the coffee bed, especially with cone-shaped drippers. What if there was a brewer that promoted a more balanced flow and fuller extraction without requiring perfect pouring technique? That’s where the KalitaWave comes in.

The KalitaWave is a flat-bottom pour-over dripper designed in Japan. Its flat base features three small holes that allow for more even water flow and extraction compared to conical drippers like the Hario V60. Whether you're brewing one cup or serving multiple people, the KalitaWave offers a reliable way to get clean, balanced coffee with less effort.

What Is the KalitaWave Dripper?

The KalitaWave is a flat-bottom manual pour-over coffee dripper originally made in Japan. Unlike the Hario V60’s single hole or cone-shaped brewers like Clever or Bonavita, the KalitaWave has a flat base with three small holes. This design encourages a more even extraction by distributing water flow across the entire coffee bed. The result is a cleaner, more balanced cup with less channeling risk. It's available in two sizes (#155 and #185) and in glass, stainless steel, and (for the larger size) ceramic materials.

KalitaWave Sizes and Materials

The KalitaWave dripper comes in two main sizes:

• #155: Ideal for brewing a single cup; uses about 17–18g of coffee with 300g water.
• #185: Designed for 2–4 people; uses around 29–30g of coffee with 500g water.

Materials vary by size: both #155 and #185 are available in glass and stainless steel, while the #185 also comes in ceramic. The stainless version is widely recommended for durability and heat stability.

What You’ll Need to Brew with KalitaWave

To brew with the KalitaWave, you’ll need a few essential tools beyond the dripper itself:

• KalitaWave filters: They are not standard-sized; you must use Kalita-brand paper filters specific to your dripper model.
• Glass server or mug: For catching brewed coffee. A Kalita glass server is common, but any vessel will work.
• Kitchen scale: For weighing both coffee and water accurately; helps hit the right brew ratio and track time.
• Gooseneck kettle: For controlled pouring. Bonavita and Kalita both make models with temperature control.
• Timer: To monitor brew time, aiming for around 3 to 3½ minutes total.

Step-by-Step: How to Brew Coffee with a KalitaWave

1. Place the Filter

Use the KalitaWave filter that matches your dripper model. Insert it into the dripper and place the whole setup on top of your server or mug.

2. Rinse the Filter (Optional but Recommended)

Rinsing the filter with hot water removes paper taste and preheats your server. Pour water directly in the center—not the edges—to avoid warping the filter. Pour enough to wet the filter and then discard the rinse water. Note: World Brewers Cup winner Erin McCarthy didn’t pre-wet his KalitaWave filter—and still won. But preheating your server is still smart.

3. Add Coffee Grounds

For best results, aim for a brew ratio between 1:15 and 1:17. That means:

• #155: 17–18g coffee to 300g water
• #185: 29–30g coffee to 500g water

Grind size should be medium to medium-coarse, similar to sea salt. Your target brew time is around 3 to 3½ minutes. Adjust your grinder finer if brews finish too fast, or coarser if too slow.

4. Bloom and Pour

You can choose either a continuous pour or a pulse (pause-and-pour) method. For beginners, the pulse method is easier to control. Start by pouring just enough hot water to saturate the grounds (about double the coffee weight, e.g., ~36g water for 18g coffee), let it bloom for 30 seconds, then continue pouring in a circular motion, keeping the water level steady. You can also pour straight down gently without swirling for an expert-level, splash-free technique.

5. Serve

Once brewing is complete (usually around 3–3½ minutes), lift off the KalitaWave and pour the brewed coffee into your cup. There’s no need to swirl or mix—the flat bottom already promotes even extraction.

Tips and Notes

• You don’t need a high-end kitchen scale to brew great coffee with KalitaWave—but it does help with consistency.
• The included 10g coffee scoop is handy if you prefer measuring by volume instead of weight.
• When using a gooseneck kettle, pour slowly and keep the spout close to the coffee bed to avoid disrupting the brew.

Frequently Asked Questions

Do I have to pre-wet the KalitaWave filter?

No, you don’t have to pre-wet the KalitaWave filter to make good coffee. While rinsing removes paper taste and preheats the server, World Brewers Cup champion Erin McCarthy brewed with a KalitaWave without pre-wetting the filter. That said, rinsing still helps warm your server and avoid paper flavors.

What’s the best grind size for KalitaWave?

The ideal grind size is medium to medium-coarse, similar to sea salt. This helps achieve a balanced extraction within a 3 to 3½ minute brew window. Adjust based on your actual brew time.

Which KalitaWave size should I buy?

Choose the #155 for single servings (about 1 cup), and the #185 for 2–4 people. The #185 also comes in ceramic if you prefer that material. Both are compatible with Kalita’s specially designed filters.

Can I use a regular V60 filter in a KalitaWave?

No, you must use KalitaWave-specific filters. They are not interchangeable with other drippers like V60 or Chemex. Using the wrong filter can affect flow rate and extraction.

How long should a KalitaWave brew take?

Aim for a total brew time of 3 to 3½ minutes. If it’s too fast, grind finer. If too slow, go coarser. Time is a key indicator of extraction balance.

What kind of kettle should I use with KalitaWave?

A gooseneck kettle is highly recommended for precise pouring. Models with temperature control (like Bonavita or Kalita’s own kettles) help you hit optimal brew temperatures, usually around 93°C.
