Able Brewing, KONE, gen 3.
We used this all weekend, for cupping on Friday and for the Gesha fest.
Pros:
1. Silicone lip over the top edge. Eliminates the sharp edge. +
2. Rounded tip is much better than the pointed end. +
3. Holes HAVE to be different. Keith has virtually eliminated sludge. No more residual fines than a drip or pourover. +
4. Fits Chemex, Hario small and large, as well as the Cilio 6. +
Cons:
None.
Others and I really worked over the Chemex and KONE 3 set-up. Excellent cup. Keith can quit designing -- I believe he has nailed it.
Rich mouthfeel without the "sloppiness" (diminished structure) that I experience in a press pot. Good oils, solid cup. I will be moving away from the standard daily vacpot arrangement and pumping out some KONE 3/Chemex coffee for the next 4-6 weeks. Very, very pleased with it.
