I recently purchased a Coava KONE from Espresso Parts in Oly. A couple of hours in the lab and I had made some solid cups of coffee. Luckily you can go to Coava’s website and watch a beautifully shot video on how to properly use the KONE. What resulted from using the KONE was interesting, I did get a lot of sweetness, the acidity was amplified and there was a lot of sediment. I love the KONE….you should buy one.
