Kopi luwak

A specialized coffee tagged the most rare and expensive coffee in the world. Coffee beans are injested by the luwak (paradoxurus hermaphroditus). The undigested beans are passed through the little civet cat's digestive system then collected by the local enthusiasts. The digestive process causes the beans to ferment and creates a very specific flavor to the later roasted beans.http://www.sallys-place.com/beverages/coffee/kopi_luwak.htm
