I've read a few things about weasel coffee and similar coffee from cats/civets/etc. I've read it was first consumed in Indonesia but is also found in Vietnam, it's expensive and there are outright fakes as well as scientifically manufactured replicas.
I am finding it hard to believe that anyone really does collect and use coffee beans that have passed through the digestive system of an animal, yet I've also read that Australian customs siezes weasel coffee because of the animal traces it contains.
So... can anyone shed any further light on the phenomenon of weasel coffee? Does it really exist - and can it be found in Hanoi?
