Kopi Luwak Coffee
Kopi Luwak is the world's most expensive coffee. The main factor for its high price is the uncommon method of production. It's produced from coffee beans which have been digested by a certain Indonesian cat-like animal called Palm Civet or Civet Cat. This is why Kopi Luwak is often called cat poop coffee or Civet cat coffee. the feces of this cat are collected, finished and sold as Kopi Luwak.
The short supply, high demand, different taste and the uncommon production methods define the value of Kopi Luwak - making it the most expensive coffee in the world.
