You can't have a discussion of the world's most expensive foods without mentioning Kopi Luwak. Originating from Sumatra, Kopi Luwak is created from coffee beans that have passed through the digestive track of the Asian Palm Civet. The civets eat the coffee berries and the undigested beans pass through their system. The beans are then collected and brewed. Many people claim that the coffee has a high level of complex acidity that cannot be achieved through any other brewing method. With only around 500 pounds of beans produced every year, the cost for a pound is upwards of $300.
