Beer Brewed with Doo-Doo Real, drinkable beer brewed with elephant poo? Yes. More specifically, a stout from Japan's Sankt Gallen Brewery called Un, Kono Kuro, brewed with coffee beans fed to elephants and then "recovered" from their excrement (at which point they are referred to as "black ivory"). Seems like a bit of a stretch, but according to one reviewer, "This is some good s***!" Seems as though one might be compelled to wash their mouths out with a bit of beer soap after drinking this one... Would you try it?
