Besides the production of regular coffee, Indonesia also produces several specialty coffees. Most famous of these specialties are luwak coffee (kopi luwak), Toraja coffee, Aceh coffee and Mandailing coffee. The first one - luwak coffee - is possibly the most famous type of coffee as it is known as the world's most expensive coffee. It is brewed from beans that have passed through the digestive system of the Asian palm civet (catlike animal). Due to this special fermentation process inside the animal (and due to the fact that the civet is able to select the juiciest coffee cherries) this coffee is believed to have a richer taste. Its labor-intensive production process and scarcity on the international market cause its expensive price.
