Hi Bombcup,
I think it might be a combination of grind and the method (Jason was using drip). I will try to get my hands on some paper filters and a porcelain filter holder and see how that tastes. I will also experiment a little with various grind settings and brewing times. I have to be honest I was shocked how good that Yirga was from the drip/Ditting and how bad it was from my Macap MC4 and FP.
