The most expensive and rarest coffee in the world is Indonesian Kopi Luwak, which is extracted from the turds of the civet cat. For a mere $150-$600 a pound, you too can drink the stuff some critter was unable to digest. Where do I sign up!
Supposedly the digestive process makes the taste and aroma stronger - make your own joke here. Supposedly it's heavy and rich, caramel and chocolatey. I'd try it if somebody else bought it for me.
But really, who thought of trying this? "Hey, that cat just pooped some stuff out. Let's roast and drink it!"
And there are articles galore on it. A university study (from the University of Guelph, who earlier reminded us not to eat poop), as well as USA Today, BBC, CBC, the East Coast Family.
