Kopi Luwak
It is the most expensive coffee in the world. "Waiter your coffee tastes like cat shit."
"Thank-you. That will be $186.50 please".
$1:
Research by food scientist Massimo Marcone at the University of Guelph in Ontario, Canada showed that the civet's endogenous digestive secretions seep into the beans. These secretions carry proteolytic enzymes which break down the beans' proteins, yielding shorter peptides and more free amino acids. Since the flavor of coffee owes much to its proteins, there is a hypothesis that this shift in the numbers and kinds of proteins in beans after being swallowed by civets brings forth their unique flavor. The proteins are also involved in non-enzymatic Maillard browning reactions brought about later by roasting. Moreover, while inside a civet the beans begin to germinate by malting which also lowers their bitterness
So many jokes about UofG so little time.

It might be good Coffee and perhaps the Civet has some unique ability to make it. However, Who and How TF did anyone discover this?
