Straight out of an email I just reveived from Mikkeller.dk
"Beer Geek Brunch Weasel. This is an imperial Oatmeal stout brewed with one of the world's most expensive coffees Cà Phê Chòn, made from droppings of weasel-like civet cats. The fussy Southeast Asian animals only eat the best and ripest coffee berries. Enzymes in their digestive system help to break down the bean. Workers collect the bean-containing droppings for Civet or Weasel Coffee. The beer will be available from the beginning of 2009."
I Shit You Not
None the less, I will try it.
