Why the Kalita Wave 155 Filter Produces Stable Brews

If your pour-over coffee tastes uneven—some sips too sharp, others weak or overly bitter—you’re likely dealing with inconsistent extraction. One major culprit? Your coffee filter’s design. Many drippers concentrate flow through just one or two small holes, leading to channeling where water finds easy paths and misses parts of the coffee bed. The result? Uneven flavor and wasted coffee potential.

The Kalita Wave 155 solves that with a flat-bottom design and three small extraction holes positioned evenly under the coffee bed, ensuring a balanced flow and reducing over- or under-extracted pockets.

What Makes the Kalita Wave 155 Different?

The Kalita Wave 155 is a flat-bottomed pour-over dripper made from stainless steel. Unlike cone-shaped brewers that funnel water through a central point, the 155 features a wide, level filtration surface. Its key feature is the three small extraction holes arranged symmetrically at the base. This layout forces water to pass evenly through the entire coffee bed rather than escaping through a single channel. The result is a more uniform extraction and a cleaner, more balanced cup.

How the Multi-Hole Base Prevents Over-Extraction

Most single-hole drippers (like the Hario V60) rely on a vortex and precise pouring technique to avoid channeling. But even small pouring errors can lead to water finding a fast route through the coffee, over-extracting those areas and under-extracting others. The Kalita Wave 155 avoids this problem entirely. With three evenly spaced holes, extraction happens across the whole bed. There's no dominant escape path, meaning you get a smoother, more consistent extraction regardless of your pour technique. The wide, flat filter also ensures even saturation and prevents the coffee grounds from being pushed to one side.

Using the Kalita Wave 155: What You Need to Know

To get the best results from your Kalita Wave 155, use it with the proprietary Kalita Wave 155 paper filter. These filters are designed with a unique folded structure that surrounds the entire brewing chamber, creating channels along the sides for water flow—further supporting even extraction. The filters also prevent any papery taste and help maintain a flat coffee bed. For optimal performance, pair the dripper with a gooseneck kettle, a digital scale, and a timer. A medium-fine grind (similar to table salt) and a standard brew ratio of around 1:15 to 1:17 (coffee to water) work well. Pour water in stages: start with a bloom, then add the rest in controlled increments to keep the bed level.

Frequently Asked Questions

Why does the Kalita Wave 155 have three holes instead of one?

The Kalita Wave 155 has three small holes to distribute water flow evenly across the coffee bed, preventing channeling and ensuring a balanced extraction. This design minimizes the risk of over- or under-extracting certain areas compared to single-hole drippers.

Does the Kalita Wave 155 work better than a V60?

The Kalita Wave 155 is not necessarily 'better' but offers a different brewing experience. It produces more consistent and balanced extractions due to its flat bed and multi-hole design, while the V60 allows for more variability and experimentation depending on pour technique.

What kind of coffee grind should I use with the Kalita Wave 155?

A medium-fine grind, similar to table salt, is ideal for the Kalita Wave 155. This grind size works well with the flat-bed design and helps achieve an even extraction when paired with proper water flow and brew ratios.

Can I use any paper filter in a Kalita Wave 155?

For best results, use the official Kalita Wave 155 paper filters. They are designed to fit the dripper’s unique shape and help create even water distribution. Other filters may not sit properly or could affect flow and taste.

Is the Kalita Wave 155 suitable for beginners?

Yes, the Kalita Wave 155 is beginner-friendly. Its flat-bottom design and multiple holes make it more forgiving of pouring technique, helping new brewers achieve consistent results without needing perfect control.
