Luwak Coffee is noted for its scaresity and most expensive coffee in the world.
Luwak Coffee are robusta or arabica coffee beans which have been eaten by and passed through the digestive tract of the Indonesian Civet (family of Viverridae).
“Kopi” is the Indonesian word for coffee and “Luwak” is local name of this animal which eats the raw red coffee ‘cherries’ as part of its usual diet. This animal eats a mixed diet of insects, small mammals and fruits along with the softer outer part of the coffee cherry but does not digest the inner beans, instead excreting them still covered in some inner layers of the cherry.
Locals then gather the beans — which come through the ‘animal stage’ fairly intact — and sell them on to dealers. It is believed that enzymes in the stomach of the civet add to the coffee’s flavour through fermentation of some type.
