The most expensive coffee in the world does not hail from Jamaica or Hawaii, but instead from Indonesia.
Kopi Luwak the most expensive coffee in the world does exist, and those who drink the expensive coffee insist that it is made from coffee beans eaten, partly digested and then excreted by the Common palm civet, a weasel-like animal.
“Kopi” the Indonesian word for coffee along with “luwak” is local name of this animal which eats the raw red coffee beans. The civet digests the soft outer part of the coffee cherry, but does not digest the inner beans and excretes them.
Apparently the internal digestion ends up adds a unique flavor to the beans, removing the bitter flavor, and then beans are then picked up by locals and sold. The most expensive coffee beans can cost up to $600 a pound, and up to $50 per cup, if you can get over the fact that you are drinking such a strange brew.
You would know if you drank the most expensive coffee in the world, because the quantities of it are tiny amounts.
