Coffee production in Indonesia in the classic Indonesian cup profile. Larger processing mills, estates and some farmers' cooperatives on Sumatra, Java, Sulawesi and Bali produce "fully washed" coffee. The most unusual form of coffee processing in Indonesia is "Kopi Luwak". This coffee is processed by the Asian palm civet ("Paradoxurus hermaphroditus"). The animals eat ripe coffee cherries and their digestive process removes the outer layers of the fruit. The remaining coffee beans are collected and washed. Coffee experts believe that the unique flavour of Kopi Luwak comes, at least in part, from the extraction of naturally occurring potassium salts from the beans during the
Kopi Luwak are eaten by a civet for their fruit pulp. After spending about a day and a half in the civet's digestive tract the beans are then defecated in clumps, having kept their shape and still covered with some of the fleshy berry's inner layers. Despite being in contact with faeces and pathogenic organisms, the beans contain negligible amounts of the enteric (pathogenic) organisms associated with feces. Moreover, the "cherry" or endocarp surrounding the bean is not completely digested by the luwak, and after being collected, the farmer performs thorough washing and removes the endocarp. The final roasting of the beans
