Kopi Luwak - World's Most Expensive Coffee

At $160 per pound, what makes this coffee so expensive ? Apparently, the cherry beans of the coffee plant are eaten by a nocturnal animal called a Luwak. Oh..this gets better. The entire bean does not get digested, just the outer layer. So it basically passes through the animal's digestive tract and is excreted..yes..pooped out. It gets washed, and then sun dried. Locals believe that the "animal stage" provides some kind of enzyme which ferments leading to the exquisite flavor it yields. It is described as a rich flavor with hints of caramel or chocolate. In short, Indonesia produces the world's most expensive coffee because of this unique processing.
