The luak, that's a small catlike animal, gorges after dark on the most ripe, the best of our crop. It digests the fruit and expels the beans, which our farm people collect, wash, and roast, a real delicacy. Something about the natural fermentation that occurs in the luak's stomach seems to make the difference. For Javanese, this is the best of all coffees—our Kopi luak.
