How Is Kopi Luwak Made?

Kopi Luwak is made from coffee beans that have been eaten, partially digested, and excreted by the Asian palm civet. The civets select the ripest coffee cherries, and enzymes in their digestive tract alter the protein structure of the beans, reducing bitterness before the beans are harvested from the waste, cleaned, and roasted.
