Introduction of CDK KONO Type Dripper

Collect Kono-type ceramic drippers has been one of my hobbies, and this dripper from CDK ceramic studio is a lucky find during my internet surfing earlier this year.

Structure: As the name already told, the design of this dripper is similar to Kono, more specifically, MD-21 (first generation). Both with twelve ribs and the length of each ribs is almost 1/2 of dripper. The top half of dripper is sealed with filter so no water will leak from the side, and the bottom half that with ribs create a large air pocket (see picture below) to allow coffee flow out and keep a stable flow rate. Something different in this dripper is, ribs don’t really extend to the bottom hole (similar to Hario V60 Kasuya Model). With this design, filter will “fill in” the hole gradually, it helps to concentrate the water but also slow down the flow rate.

Personal tips: The flow rate of this dripper is stable and belongs to Medium-Slow side in cone shaped drippers, which leads to a sweet and mellow cup. There are two methods I used for this dripper, the first one is: blooming, then two big circle pours to rise the water level and let it drain down, and do a small, slow circle pour to finish. This method makes good use of the flow rate difference on top half and bottom half of the dripper, and due to a longer immersing time, coffee will show more complexity, intense and heavier body. The second one is: blooming, then do multiple quick, small pours (2 to 3 times depend on situation), try to keep the water level at coffee bed on each pour, and one big pour to finish. In this method, we use the faster flow rate in bottom half and rise the extraction rate by multiple pours, coffee will show more acidity and layers of flavour. I use method 1 most of the time due to personal preference.

P.S. Beside its functionality, it is also a beautiful handcrafted pottery.
