Kopi Luwak is a very rare type of coffee that is suppose to be the best of the best but it is not made from a coffee bean or it comes from a special cat poo. A cat called the civet.
Kopi Luwak 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 Luwak process takes place on the islands of Sumatra, Java and Sulawesi in the Indonesian Archipelago.
"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.
Kopi Luwak in coffee shops will cost $80 for a 4 ounce cup or $450 for a pound.
