It's a coffee from Jamaica, and is quite expensive (but not THE
most expensive lor, that would be like the Kopi Luwak).
Unfortunately, the Japanese buy most of the Blue Mountain stocks
each year, so it's not SO easy to get it cheaply outside of here in
Japan. It has a decent mild taste, not too bitter or acid. But it
is kind of over-rated and you can get very very decent coffees for
less. TCC seems like a good place to go to. I do visit when I go
back to SG.
