Kopi Luwak comes from the excrement of an animal called civets (commonly known as civets in Indonesia). Although it comes from smelly poop, it only feels sweet and indescribable sweetness after a sip. This wild musk cat likes to eat fat and pulpy coffee fruits, but the hard hard nuts (raw beans) are indigestible and are excreted with feces. After being cleaned, they become Kopi Luwak coffee raw beans! So many people call it "cat shit" coffee. The Indonesians found that the coffee beans fermented by the civets' intestines and stomach are particularly thick and mellow, so they collect the civets' feces, sift out the coffee beans and brew them to drink. Because the yield is rare and the fermentation process is unique, the flavor is very different from that of ordinary coffee. Traditionally, coffee fruit is washed or sun-treated to remove the peel, pulp and sheep skin, and finally take out the coffee beans. However, Luwak uses natural fermentation in the body to remove the coffee beans, so it has a special flavor.

It is said that early Indonesian coffee farmers regarded civets that specialize in ripe coffee fruits as mortal enemies, but at some point someone began to think of picking coffee beans from the civet droppings to make a unique Kopi Luwak. Coffee experts everywhere have tried and were amazed. Since then, local farmers spend a lot of time collecting civet droppings in the forest every day during the coffee ripening season.

Kopi Luwak is produced by the feces of Indonesian coconut cats (a kind of civet) as raw materials, so it is called "Kopi Luwak". This kind of animal mainly feeds on coffee beans. After completing fermentation in the coconut cat's stomach, it destroys protein, produces short peptides and more free amino acids, reduces the bitterness of coffee, and then excretes feces as the main raw material. Because coffee beans cannot be digested, they are excreted and Kopi Luwak is made after washing and baking. Coffee critic Chris Rubin said, "the aroma of the wine is so rich and strong, and the coffee is incredibly rich, almost like syrup." Its thickness and chocolate taste, and lingering on the tongue for a long time, pure aftertaste. The civet likes to choose the most ripe, sweet, juicy coffee fruit in the coffee tree as food. The coffee fruit passes through its digestive system, and only the pulp on the outside of the fruit is digested, and the hard coffee beans are then excreted intact by the civet's digestive system.

In this way, in the process of digestion, the coffee beans have an unparalleled magical change, the flavor tends to be unique, the taste is particularly mellow, and the rich, round and sweet taste is also incomparable to other coffee beans. This is because the civet's digestive system destroys the protein in the coffee beans, making the Kopi Luwak much less bitter from the protein and increasing the roundness of the coffee beans.
