Actually this is a difficult one- as coffee served in homes in Indonesia and called "Kopi Luwak", is actually nearly all the time (but not always) coffee picked super ripe from the tree. Its called Kopi Luwak because it is the coffee (kopi) that would have been eaten by the Luwak if it had got the chance to get there first :grin: Also one of the biggest brands in Indonesia is "Kopi Luwak" (complete with a picture of a rather stretched looking luwak) on the outside of the packet. Again this is not kopi luwak "asli" (original) but rather hopefully as above. The packet does say "with luwak flavouring added", or something along those lines.
If your wife did infact have real kopi luwak (ie from the animal, rather than the packet) then she was probably very fortunate. As mentioned it is not a favourite in the city or larger towns, but is drunk in the kampung. I would imagine she was also fortunat that the coffee was most likely consumed by a luwak living in a fruit rich environment, as the luwak (an ominivore) often eats mice, eggs etc which give KL a rather gamey and not too pleasant cupping character.
Either way, good to always see posts from those who live (or have lived) in Indonesia. I would also give you "2 thumbs up" for your Durian comments. I am a huge Durian fan and have an excellent Durian and coffee recipe which I was given by a roaster in the Philippines. Excellent fruit alone or also consumed with a sprite chaser :shock:
