Most expensive coffee. Do you know how this is prepared?

Kopi Luwak, the most expensive coffee in the world selling for between $100 and $600 USD per pound or about $50 a cup. Its also known as Civet coffee or Weasel coffee. Kopi Luwak is an Indonesian word, Kopi which means coffee, and luwak is a common name of a cat size mammal Asian Palm Civet. Kopi Luwak has an exceptional aroma and most pleasing taste.
But I’m sure many of us don’t know how this delicious coffee is obtained. Civets consumes red coffee cherries, containing fruits and seeds. But, its not able to digest the coffee beans so they are passed out. The beans and collected washed and dried. Though Civets are not able to digest the beans but their digestive juices penetrate the beans break down the proteins and enhance its flavour.
We may worry about the safety, but rigourous washing, sun drying and roasting at high temperature help to eliminate bacteria making it a safe coffee.
Really, an unusual way to get an unusual flavour…….
