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
Giling Basah called “luwak”. The coffee beans, still coated with mucilage, are then stored for up to a day. Afterwards the mucilage is washed off and the parchment coffee is partially dried for sale, retaining only 30% to 35% of the moisture content. Processors and collectors then hull the coffee in a semi-wet state, which gives the beans a unique bluish-green appearance. This method is thought to reduce acidity and increase body, resulting in the classic Indonesian cup profile. The Giling Basah process can create a "goat's foot," a split on one end, in green coffee beans. Sometimes the hulling machine partially
