As the international demand for kopi luwak increased, some producers turned to caged production methods to increase yields. Traditionally, excreted coffee beans were collected directly in plantations and forests.

When performed in nature, or in the wild, these two mechanisms achieve the same goal as selective picking and the wet or washed process of coffee milling: 1) harvesting optimally ripe cherries and 2) mechanically and chemically removing the pulp and skin from the cherry, leaving mainly the seed. The beans begin to germinate by malting, which reduces their bitterness. This selection influences the flavour of the coffee, as does the digestive process. The palm civet is thought to select the most ripe and flawless coffee cherries. In the roasting process, the proteins undergo a non-enzymatic Maillard reaction. This alters the composition of amino acids and impacts the aroma of the coffee. During digestion, digestive enzymes and gastric juices permeate through the endocarp of coffee cherries and break down storage proteins, yielding shorter peptides. Kopi luwak is brewed from coffee beans that transversed the gastrointestinal tract of an Asian palm civet, and were thus subjected to a combination of acidic, enzymatic, and fermentation treatment.

In the 19th century, farmers in central Java started to brew and drink coffee from excreted beans collected at their plantations. The origin of kopi luwak is closely connected to the history of coffee production in Indonesia Dutch colonialists established coffee plantations in Indonesia and imported beans from Yemen. Another epithet given to it is that it is the 'Holy Grail of coffees.' History Īlthough kopi luwak is a form of processing rather than a variety of coffee, it has been called one of the most expensive coffees in the world, with retail prices reaching US$100 per kilogram for farmed beans and US$1,300 per kilogram for wild-collected beans. This method of production has raised ethical concerns about the treatment of civets and the conditions they are made to live in, which include isolation, poor diet, small cages, and a high mortality rate. The traditional method of collecting feces from wild Asian palm civets has given way to an intensive farming method, in which the palm civets are kept in battery cages and are force-fed the cherries. Producers of the coffee beans argue that the process may improve coffee through two mechanisms: selection, where civets choose to eat only certain cherries and digestion, where biological or chemical mechanisms in the animals' digestive tracts alter the composition of the coffee cherries. 'Weasel coffee' is a loose English translation of its Vietnamese name cà phê Chồn. It is also widely gathered in the forest or produced in farms in the islands of the Philippines, where the product is called kape motit in the Cordillera region, kapé alamíd in Tagalog areas, kapé melô or kapé musang in Mindanao, and kahawa kubing in the Sulu Archipelago. Kopi luwak is produced mainly on the Indonesian islands of Sumatra, Java, Bali, Sulawesi, and in East Timor. Asian palm civets are increasingly caught in the wild and traded for this purpose.

The cherries are fermented as they pass through a civet's intestines, and after being defecated with other fecal matter, they are collected. Kopi luwak, also known as civet coffee, is a coffee that consists of partially digested coffee cherries, which have been eaten and defecated by the Asian palm civet ( Paradoxurus hermaphroditus).
