Kalita Wave 185 - Stainless Steel The Stainless Steel Kalita Wave Dripper 185 is thoughtfully crafted for achieving a strong robust coffee taste without the harsh bitter bite for all your pour-over coffee brews.

When hot water is poured it does not accumulate but quickly drips to the Wave Zone avoiding bitterness and the result is a solid brew. The Kalita Wave is easy to use and will delight baristas and beginners alike. Don’t forget to add the Kalita Wave 185 filters for a better coffee brewing experience.
