Indonesian kopi luwak is often cited as the most expensive coffee in the world. It is made from coffee beans that are digested and excreted by the civet (luwak)—a catlike mammal that is native to Southeast Asia—before they are washed, ground, and roasted.
It is believed that when the coffee beans pass through the animal’s digestive tract, they lose their astringency, which makes the coffee softer, smoother, and less bitter. The coffee was allegedly discovered in the 19th century during the Dutch colonial rule when the local farmers were forbidden to harvest coffee for their personal use.
Since it is almost impossible to get the beans from wild animals, most producers keep the animal in cages, and in some cases, the civets are force-fed. These conditions often raise concerns over animal rights and the entire future of the civet population.
