This seems to be a popular topic lately, and while I have written about this in greater detail in my story The Straight Poop on Kopi Luwak Coffee a couple new sites have come to my attention since then to warrant a re-visit.
Most notable is AnimalCoffee.com which hosts some of the only images I’ve seen of the Luwak, the Indonesian animal which eats raw coffee cherries and excretes undigested coffee beans in its droppings.
They also have the only pictures I’ve ever seen of the droppings before processing. They sell attractively packaged Kopi Luwak coffee gift boxed with your very own luwak dropping. Check out their souvenir page for a very attractive paperweight.
