What is weasel coffee or Kopi Luwak?

Weasel coffee or Kopi Luwak translates as "Civet Coffee" and is created in several regions of the world where the Palm Civet or similar species resides. Palm Civets are primarily "frugivores" (fruit eaters) and were once considered a pest by coffee farmers, because the furry little beasts would feed at night on only the ripest coffee cherry fruits. They would swallow the coffee fruit and bean in its entirety, dissolve the fruit away from the bean, and pass the beans onto the ground by morning. At some point some frustrated farmer decided to wash the beans and roast them, and was amazed to discover the best coffee he had ever had. Now, many years later, the Civet is literally treated more like the Goose that Laid the Golden Egg than a pest, for obvious reasons, since Kopi Luwak coffee can fetch from $180 to $600 per pound and is the world's most expensive coffee.
