Kopi Luwak originates in Indonesia. Touted as the World's Most Expensive Coffee, the product's uniqueness is attributed to its unusual journey through the digestive system of the civet, a tree-cat. Basically they eat the coffee berries, and crap the whole beans out the other end. These are then collected, cleaned and processed for sale. Having a partner who lives in Indonesia who knows my appreciation of a good coffee, he was kind enough to fork out the big bucks to bring a packet home for me to try.
So the verdict? For me it was different, and after reading the Wikipedia article about it, I understand this is because it lacks the bitterness of the coffee we are used to, and I admit that I usually select coffee based on their strength and bitterness. I also wonder if having ground coffee as opposed to beans may have affected it's freshness. But it was definitely not crap.
PS Kopi Luwak appeared in this scene of the movie The Bucket List. Quite funny :)
