My take on this is that the "product recommendation" might be a little misleading. Let's focus instead about what you're really asking, and what type of answer you're looking for. It seems that there's quite a bit of interest in the topic of Kopi Luwak, because there are several questions about it and much discussion. I think there's a lot of room for interesting Q&A related to this topic!
Fundamentally, what's your question or what are you trying to solve? From your initial question, it sounds like...
- you have never tried Kopi Luwak;
- you don't know how it tastes,
- you are unable or unwilling to try it;
- you are looking for an alternative.
Are any of those a more fundamental question that you have? How about changing the question to, "What does Kopi Luwak taste like?" Then you can also ask in the body of the question, or infer from the answer, "What other coffees taste like it?" Though similar in concept, I think "how does it taste" comes across better. What do you think? I'd be happy to re-articulate the question with you, or un-lock it if you change it around. For example:
What does Kopi Luwak taste like?
I have never had the opportunity to try Kopi Luwak, but I'd like to know how it tastes. How is does the taste differ from more traditionally processed coffee from the same region? Are there other coffees that have similar tasting notes?
Or something like that. That said, this answer says Kopi Luwak is delicious, and has some descriptions, but there's probably room for another question on the topic.
Another question might be something more like "Why does Kopi Luwak taste different?" For example, what is it about the Kopi Luwak digestion process that changes the beans? What happens to the beans during digestion (e.g., protein digestion)?
There might also be room for a question about Black Ivory Coffee, which is apparently coffee digestively "processed" in a similar way by rescued elephants.
