JAKARTA, Indonesia - Indonesia's top Islamic body declared on Tuesday that Muslims can drink civet coffee - the world's most expensive coffee - which is extracted from the dung of civet cats.

A preacher recently suggested the beverage might not be "halal" - or religiously approved - because its unusual provenance makes it unclean. But after a long discussion on Tuesday, the influential Indonesian Ulema Council said that the coffee, known locally as Kopi Luwak, could be consumed as long as the beans were washed.

Kopi Luwak, which takes it name from the Indonesian word for civet, is made from hard beans that have been eaten by the nocturnal critters and then fermented in their stomachs before being pooped out and roasted. Civet cats are mongoose-like animals.

It's highly prized for its smooth flavor and bitterless aftertaste, sometimes fetching well over $200 a pound ($440 per kg) online.

"Kopi Luwak can be declared 'halal' after passing through a washing process," said Maruf Amien, acting head of the council. "Producing, selling and drinking it is allowed."

In Indonesia, the world's most populous Muslim nation, Kopi Luwak is produced in the main Java island, Sumatra and Sulawesi.

It is also found under different names elsewhere in Southeast Asia.
