A British department store is selling a special coffee, harvested from the dung of Indonesian jungle cats, for $100 a cup.

The pricey coffee known as Caffe Raro is a blend of extremely rare Jamaican Blue Mountain coffee and Kupi Luwak, an Indonesian coffee bean that is harvested from the bodily waste left behind by Indonesian civet cats, The Daily Telegraph reported Thursday.

Even so, the Peter Jones store says the luxury blend is one of the world's rarest and most expensive coffees.

The beans of Kupi Luwak are harvested after being ingested by civet cats, and only about 260 kilos (about 573 pounds) of the coffee is produced each year.

"The cats select the best beans to chew. The flesh of the fruit are ingested and the hard beans are evacuated. It's rather like a natural filtering process," said Carie Barkhuzen, a spokeswoman for the upmarket store in London's Sloane Square.

The coffee, which went on sale Thursday, is available at $100 for a shot at the Peter Jones Espresso Bar, or shoppers can buy 100g (3.5-ounce) packs of the coffee beans to take away for the same price.

"It's not exactly flying off the shelves -- it's very expensive, after all -- but customers are buying it," Barkhuzen said.

The proceeds from the coffee sales will go to charity.

英国一家百货商店目前正在出售一种特殊的咖啡，这种咖啡取材于印尼一种丛林猫的粪便，每杯售价100美元。

据《每日电讯报》本周四报道，这种昂贵的“猫粪咖啡”由极为稀少的牙买加蓝山咖啡和印尼鲁瓦克咖啡豆混合调制而成，鲁瓦克咖啡豆是从印尼麝香猫的排泄物中提取出来的。

尽管是“猫粪咖啡”，但彼特•琼斯商店称这种咖啡是世界上最稀少、最昂贵的咖啡品种之一。

鲁瓦克咖啡豆从麝香猫消化后排泄的粪便中提取出来，每年的产量仅有约260千克。

据这家位于伦敦斯隆广场的商店的女发言人凯莉•巴克胡兹恩介绍：“麝香猫只挑选最香甜的咖啡果实食用。果肉被消化掉，坚硬的咖啡豆则被排出体外。这很像一个自然过滤的过程。”

这款咖啡已于本周四在彼特•琼斯浓缩咖啡馆上架，每杯售价100美元，顾客也可以同等价格购买100克的咖啡豆带回家享用。

巴克胡兹恩说：“这款咖啡卖得不算快，毕竟它比较昂贵，但还是有人买。”

“猫粪”咖啡的销售收入将捐给慈善机构。
