Kopi luwak, or civet coffee is produced mainly on the Indonesian islands of Sumatra, java, Bali and Sulawesi. The history of this rare delicacy stems from Dutch coffee plantations which were established in these areas during the 18th century. Locals and plantation workers were forbidden to pick the coffee fruit for their own use, however they realized that a species of musang or luwak (the Asian Palm Civet), a cat like creature consumed the coffee fruits, yet they left the coffee seeds undigested in their droppings. The natives collected these luwaks' coffee seed droppings, then cleaned, roasted and ground them to make their own coffee beverage. Eventually the Dutch plantation owners became aware of this coffee and it became their favorite. It was expensive even in the colonial era because of its rarity and unusual production process.
Most professionals in the coffee industry say that Civet coffee is usually purchased because of its rarity, price and the story behind it rather than having an outstanding taste profile. Many professional taste testers have not rated it any higher than any of the other good coffees on the market, with one even saying that it tasted just like Folgers coffee, which is hardly remarkable or worth $600 per pound.
There is also growing concern that the civets are now being caged up and force fed the coffee fruit to increase production levels, which makes civet coffee quite unethical and something I doubt you’ll ever be seeing at a Starbucks.
