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
Coffee production in Indonesia farmers remove the outer skin from the cherries mechanically, using rustic pulping machines, called "luwak". The coffee beans, still coated with mucilage, are then stored for up to a day. Following this waiting period, the mucilage is washed off and the coffee is partially dried for sale. At least one U.S. manufacturer, soft drink producer Bai, purchases the non-bean remnants of coffee cherries for use in their products. Otherwise, these remnants are discarded. Collectors and processors then hull the coffee in a semi-wet state, which gives the beans a distinctive bluish-green appearance. This process reduces acidity and increases body, resulting
