Where does Luwak Coffee come from?

Kopi luwak or civet coffee, is coffee that includes partially digested coffee cherries, eaten and defecated by the Asian palm civet. Fermentation occurs as the cherries pass through a civet's intestines, and after being defecated with other fecal matter, they are collected.
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 and in East Timor Weasel coffee is a loose English translation of its Vietnamese name cà phê Chồn.
