Kopi Luwak source:

Kopi Luwak, produced in Indonesia, is one of the most expensive coffee in the world. Indonesia grows a lot of coffee crops, including wild animals called civets, omnivores, pointed mouths and dark gray fur. The favorite food is fresh coffee beans, which are fermented and digested in the body and eventually excreted by cats. Feces are grains of coffee beans and become the most expensive feces in the world. Because the quantity is very rare, so the price is very expensive. Civet cats are found in Indo-China, India (northeast), Bangladesh, Bhutan, Sikkim, Nepal and Kashmir, but can produce Kopi Luwak.

Only Sumatran civets, or Indonesian civets,

After processing and baking, Kopi Luwak has become a luxury coffee drink and spread to luxury kingdoms around the world. Local coffee farmers, in pursuit of high profits, bring wild civets home to raise them so that they can produce more Kopi Luwak. However, the Kopi Luwak produced by breeding civets will be much worse in color and taste. Even so, the output of this kind of coffee is still very rare, and it is not affordable for all people who like coffee.
