Good cup. A pile of fines at the bottom. Bunn commercial grinder.
Might be worth $60 for someone with an expensive grinder. There's no way I'd recommend this to the average consumer, even if they had a passable burr grinder.
What shape are those burrs in? With my KONE/MACAP set-up (just 58mm burrs), I get a residual dust about the size of a dime in a Chemex. Amount isn't worth mentioning. Superb cup. Guess our experience differs.
I am a ritual-type with the morning routine. I am using the KONE 3 with the Chemex, then pouring the finished coffee into a preheated Zojirushi 1-liter insulated serving thermos. High putz, high satisfaction. Meets the 'need-a-ritual' factor.
Couldn't figure out Peter's "Bonavita bumps the KONE" until I did it with my goose necked Paico this morning. I am also using the NCho theory of pouring - get the spout right down tight. With the Paico, I can keep a crest going on the coffee wherein the tip of the spout can touch the crest. I keep it right above that, for a continuous pour instead of the pulse pour.
He was smart to deal with the sharp point and sharp edge. I think that kept it out of retail shops -- worker's comp issues/staff safety. It is a breeze to clean up in comparison to earlier models. No need to gingerly pamper it during the wash. Love it.
