- Charcoal coffee (Charcoal coffee)

The "kopi joss" or charcoal coffee has become a specialty of the city of Yogyakarta (Jogja), on the island of Java. Although sold on "angkringan" (mobile stands), this coffee is made from the best coffee beans from Klaten and Jogja. Unlike Vietnamese coffee, Indonesians do not use filters, snowshoes or other devices to prepare it. They simply put coffee powder directly into a cup. The water for cooking the coffee must come from a large tin pot. It is believed that cooking with charcoal gives a different flavour than cooking with a regular gas stove. The boiled water is added directly into a glass containing coffee powder and a moderate amount of sugar. Then people stir to dissolve the coffee with the sugar.  This kind of noise can only be felt when you are close by. This also explains the Indonesians' name "kopi joss". After adding charcoal, the seller will use a small spoon to dip the charcoal into the glass. The lump of coal in the coffee is used only once during combustion. "kopi joss" appeared more than 30 years ago. To explain the origin of this particular coffee, it is said that an old man used it to boil water but unfortunately he dropped a piece of coal into a half-empty coffee cup. After tasting and feeling that the coffee tasted different when there was coal inside, he decided to market it.


- Luwak Coffee

The "kopi luwak" is a coffee harvested from the excrement of an Asian civet, the luwak (Paradoxurushermaphroditus) of the viverridae family, due to an almost absent digestion. The civet consumes the coffee cherries, digesting their pulp but not their stone, which is found in its excrement.

The coffee beans of the luwak civet will be washed and used to make the most expensive coffee in the world. The price is about US$35 to US$100 per cup. Kopi luwak is no longer wild civet coffee. Most luwak civets are caught and caged in cages on giant coffee plantations.

"Like foiegras, civets are forced to eat coffee beans," SuwannaGauntlett, founder of the Wildlife Alliance, told Globalpost. In 2013, coffee expert Tony Wild called for an end to the exploitation of civets to harvest kopi luwak. Civets are stressed when they live near each other. A diet based solely on coffee causes them many health problems.
