Kopi Luak or Civet coffee is made from coffee berries which have been eaten by and passed through the digestive tract of the Asian palm Civet and other related Civets. The Civet eats the berries, but the beans inside pass through their system undigested. This process takes place on the islands of Sumatra, Java, Bali and Sulawesi in the Indonesian archipelago. Also found in the Philippines.”motit coffee” in east Timor “cafe-laku and in Vietnam “weasel coffee”.
This coffee has a low production which makes it quite expensive. If you can get some I recommend you try it with your espresso coffee machine.
