The coffee is called Kopi Luwak.
Luwak is the local name for the Palm civet in Indonesia.

Call it Civet Coffee if you prefer!
It is also named Kape Alamid in the Philippines and weasel coffee in Vietnam. As you can see from the link, most of the info in Wikipedia is already in this thread.

What isn't in this thread is taste test reports.

That's your assignment, dear DiningBuzz reader... Use your trip through SE Asia or abroad as a reason to try what is supposed to be a great coffee.

You heard it first on FT.

Further to that first link, the ability of the Luwak/civet to choose the ripest berries to eat is a good reason to choose 'wild' luwak beans rather than those farmed through luwak in cages.

The synthetically processed bean story there is interesting too.
Recommended reading, roasting and drinking. Maybe.
