Do you mean Kopi Luwak, the coffee from Indonesian civet poop?
According to James Hoffmann[1], people should stop consuming that as the industry is based on animal abuse and it's nearly impossible to verify your Kopi Luwak has been gained through fair practices that haven't harmed the animals.
If you are coffee aficionado then better stick to Fairtrade coffee that doesn't involve any animals.
A while back I visited a kopi luwak farm in Vietnam, Hue I think it was. The animals were treated really well, but I'm sure that's not going to be the case for all these places.
Anyway, kopi luwak really is amazing stuff - but at the farm I tried "weasel coffee" and "chemical coffee" side by side (the same beans, with the same grind and roast), and I couldn't tell the difference.
I am a fan of quite a few Asian coffee beans, however. Monsooned Malabar is one of my faves as well as some strong flavoured Indonesian beans. I really enjoyed some Thai beans that I bought in a small batch although the flavour was definitely funky and not to all tastes.
If you're a coffee afficianado, watch this video [0] and don't try it.
No, it is not. If we disregard the ethical issues surrounding the coffee, this is what a renowned roaster has to say about the coffee
""" Kopi Luwak. Made from poop, smells like poop and tastes like poop. A complete ripoff to buy in to… """
A much better version of poop coffee is Jacu Bird coffee. They tend to live around good quality coffee plantations and they have a discerning eye for the coffee cherries. Still more of a novelty thing though as it's so expensive. AFAIK Jacu birds aren't force-fed in captivity, so that's much better.
