The most expensive coffee-Ruwak

The most expensive coffee in the world-Kopi Luwah coffee from Sumatra. The price is as high as $300 per pound!

Usually, after the coffee fruit is picked, the peel, pulp and silver skin are removed either by the sun or by washing. But Ruwak coffee takes advantage of natural fermentation in the animal's digestive system to extract coffee beans. The civet in the mountains of Indonesia likes to eat a kind of coffee fruit called "Ruwak". The seed coffee beans of the fruits eaten by civets cannot be digested and will be excreted with the excrement of civets. Indonesians found that the Luwak coffee beans fermented by the civets' intestines and stomach had a rare and peculiar aroma, so they collected the civet's feces, separated the coffee beans and brewed coffee. Because the output is very small, it is currently the most expensive coffee in the world.
