Yep I used to like Kona but went back to Yuban.Until proven otherwise, KopI Luwak, obtained from the excreted coffee beans of certain civets, is overpriced novelty coffee.
Same with Jamaica Blue Mountain and Hawaii Kona (which I have roasted and which are EXCELLENT but not better than coffees one eighth of the price), as well as Panama Geisha (which I have refrained from purchasing).
