Producers of the coffee beans argue that the process may improve coffee through two mechanisms, selection – civets choosing to eat only certain cherries – and digestion – biological or chemical mechanisms in the animal 's digestive tract altering the composition of the coffee cherries.
The traditional method of collecting feces from wild civets has given way to intensive farming methods in which civets in battery cage systems are force -fed the cherries. This method of production has raised ethical concerns about the treatment of civets due to "horrific conditions" including isolation, poor diet, small cages and a high mortality rate.Although 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 €550 / US$700 per kilogram.Kopi luwak is produced mainly on the islands of Sumatra, Java, Bali and Sulawesi in the Indonesian Archipelago. It is also widely gathered in the forest or produced in the 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 island, and kahawa kubing in the Sulu Archipelago ), and in East Timor (where it is called kafé-laku). Weasel coffee is a loose English translation of its Vietnamese name cà phê Chồn.
The origin of kopi luwak is closely connected with the history of coffee production in Indonesia. In the early 18th century the Dutch established the cash - crop coffee plantations in their colony in the Dutch East Indies islands of Java and Sumatra, including Arabica coffee introduced from Yemen. During the era of Cultuurstelsel (1830–70), the Dutch prohibited the native farmers and plantation workers from picking coffee fruits for their own use.
