Some just call this “The Wave” and it is offered from Kalita Co., a family owned Japanese company which has been making coffee since the 1950s.
The Kalita Wave dripper is a pour-over, similar to the Chemex or V60 but has a noticeably different extraction configurations. Rather than the water dripping through a single hole, the water drips through three extraction holes with the Kalita Wave’s flat bottom.
This allows for a crisp cup since there is no channeling of water in the coffee bed
- Place and rinse Kalita Wave filter in the dripper while on the scale. This will also heat up your mug.
- Discard the rinse water from the carafe or mug and place the 21g of fresh ground coffee into the filter - make sure the bed of coffee is flat then place the Kalita Wave on top of a carafe or mug. Tare your scale to zero.
- First Pour (:10 seconds) - Saturate the grounds with 60g of hot water off the boil (205°F) in the first 10 seconds and allow it to bloom. Coffee degasses or blooms when it’s fresh and you should see the coffee bed rise up and bubble a bit. Give it a stir with a spoon.
- Second Pour (:45 seconds) - At :45 seconds, pour water up to 200g in a spiral motion by 1:00. The spiral motion helps even the extraction and keeps everything integrated.
- Pulse and Wait - Pour small amounts (25 -50g of water) periodically to hit 375g by 2:00. Submerging dark spots and avoiding light spots and slowly bring the water level to the top for an even extraction.
- Serve and enjoy - total brew volume should be about 300ml or 10 oz mug at 2:45 to 3:00 minutes of brew time. Remove the Wave from the carafe or mug and in the sink for the rest of the water to drain through.
