My mind blowing experience of coffee came from Bali. I haven't had coffee exploratory trip in about a year. I normally do few times but I have been busy opening few more coffee shops and just haven't had chance. Bali and Indonesia is very close by but they do have some distinctive differences in flavor. If you would like, I can send you the link to the coffee I have tried.
When I had Kopi Luwak, it was from Indonesian government program. They wanted to promote their product and that was the part of experience I had privileged of having to try last year. Before that, I was in Japan when I had my cup about 4 years ago. The flavor is very complex and very aromatic. Nothing was very over kill or over powering but very gentle and persuasive. It almost like complex blend but came from just one bean. That was my experience of Kopi Luwak. I would have given around 90-91. Not over 92 if I had to give points.
