I'm finding the Kone to highly dependent on the grinder. My normal grinder for pourover (and press pot) is a KitchenAid Proline. Yesterday I tried my Compak K10, and you would think it was a different coffee; sweeter, better-defined flavors, less sludge, vs. slightly flatter and edgier flavors from the KA. The coffee I used was a very good Guat sample from Vournas, already about 12 days old, so it wasn't a matter of the bean coming into its own due to more rest. I have enough to go back and forth a couple more days, so I'll test it out again.
