The most expensive coffee in the world comes from civet poop. Kopi Luwak are coffee beans that come from Civet (a cat sized mammal) poo. The animals gorge on only the finest ripe berries, and excrete the partially-digested beans, which are then harvested for sale. Kopi Luwak is the most expensive coffee in the world, selling for between $120 and $600 USD per pound, and is sold mainly in Japan and United States, but it is increasingly becoming available elsewhere. My question is: who the hell discovered that it tasted good?
