I could go for some right now! Not Kopi Luwak - just plain joe. :-)
I have not had the pleasure of drinking a Kopu Luwak although the Trung Nguyen site offers a special coffee that has been treated with enzymes to replicate a bean's travel through a weasel's gut called "Legendee." At $17 for 9 oz. I'd probably just get a pound of Kona. That's a smooth cup too. :-)
