The world’s most expensive cup of coffee - made partly from cat droppings - is to go on sale at £50 a time.

The brew is a blend of Jamaican Blue Mountain coffee and Kopi Luwak, a south-east Asian bean collected from civet cat droppings that sells for £324 a kilo.

Created by expert David Cooper, the blend is on sale at Peter Jones department store in London.

It is believed to be the most expensive cup of coffee in the world, reports the Daily Telegraph. Proceeds go to the MacMillan Cancer Trust.

Mr Cooper said: “These rare coffees have been slowly hand roasted for around 12 minutes to ensure that we maximise the potential of each coffee.

“The final roast colour is quite dark to ensure that the espresso is perfect for a smooth latte or cappuccino.”

Kopi Luwak (”civet coffee”) is made from partially digested beans recovered from the droppings of the civet cat, a native of Indonesia.

They are said to pick the best and ripest coffee berries, before digesting the flesh of the fruit, leaving just the bean.

Customers will be relieved to know that workers wash the dung away from the beans before sale.
