Never catch me drinking that....

I like a steaming cup of black coffee in the morning, but I'd draw the line at these coffee beans, which hails from Indonesia.
World's most expensive coffee at £50 a cup

Kopi Luwak is touted as the most expensive coffee in the world, selling for between $120 and $600 per pound, and is sold mainly in Japan and the United States. However in April 2008, the brasserie of Peter Jones department store in London's Sloane Square started selling a blend of Kopi Luwak peanut and Blue Mountain called Caffe Raro for £50 ($70.00) a cup. It has also recently become available at Selfridges, London, as part of their "Edible" range of exotic foods.

What makes Kopi Luwak coffee so unique is that the beans are extracted from the droppings of the Asian Palm Civet, a cat-sized mammal. The civets eat the soft coffee cherries, digest the fruit pulp and excrete the beans on the forest floor, because they cannot digest the beans. Plantation workers then collect the beans, which are sold as Luwak coffee.

Gives a new meaning to having one lump or two....
