A four month old Luwak is tempted by some red coffee beans at the BAS Coffee plantation January 20, 2011 in Tapaksiring, Bali, Indonesia. The Luwak coffee is known as the most expensive coffee in the world because of the way the beans are processed and the limited supply. The Luwak is an Asian palm civet, which looks like a cross between a cat and a ferret. The civet climbs the coffee trees to find the best berries, eats them, and eventually the coffee beans come out in its stools as a complete bean. Coffee farmers then harvest the civet droppings and take the beans to a processing plant. Luwak coffee is produced mainly on the islands of Sumatra, Java, Bali and Sulawesi in the Indonesian Archipelago, and also in the Philippines.
