I'm not sure if anyone will find this beneficial but I shall try...
I was, of all places, in Hawaii when this was available for me to try. This was quite some time ago but it was still somewhere near $12 for a cup. I didn't care about the expense and simply wanted to try it because, well, it was available and I'd never tried it before and I'd been told it was both "very good" and "quite the experience."
The latter was certainly correct but I can't imagine thinking that the former is true under any circumstances?
I opted to try it unadulterated, no sugar and no cream. No, it didn't taste like fecal matter. It tasted as if someone had let the coffee burn at the bottom of the pot. It was oily, harsh, and did not taste good at all. It had a taste, to me, like burned coffee. It reminded me a bit of the coffee that I'd had served to me years ago in Turkey - like it was a bad imitation of bad coffee. It seriously was not pleasing, not even remotely pleasing at all.
I had paid, as I said, something close to $12 for said cup of coffee so I finished it. I'd ordered it and the intent was to try it. It was ordered mostly so I could have the experience and recount it later in life or, at least, remember it. I'd hoped to enjoy the experience and I'd hoped to be able to tell people that, "You should definitely try this! It's got to be the best coffee I've ever had."
I can not do so. I can only say that I've tried it and that I, personally, found it not only to not be anything special but something that should be avoided. It's not like a single cup is that expensive so if you still feel inclined to try it after having read this then, by all means, you should.
I have been told, since then, that it was, "Obviously fake." I have also been told that it may be the harvesting method? That some people farm the animals and just cram 'em full of beans and this means that the animal is just eating any bean fed to it. I've been told that the person who made it must not know what they were doing. I'm still more inclined to think that it was just really bad coffee. It had a distinct flavor and that flavor was not good.
Again, it reminded me of the coffee that I had in Turkey only that won't make any sense to anyone unless they've had Turkish coffee. The coffee I was served, multiple times in multiple places, in Turkey was burnt and very strong - strong to the point of absurd. Also burnt to the point of gross. It was bitter, burnt, and stronger than anyone should make coffee. It was served like that anywhere that I went so I am assuming it is a cultural thing and I've heard people mention it since. I've even heard a few people claim to like it.
Now, that's the best that I can describe Turkish coffee. Imagine that only make it oilier (Wow, that's a word and I spelled it correctly the first time? Heh!) and make it basically taste like a cheap imitation of that. Oh! Imagine espresso from a gas station as compared to espresso from a coffee shop that actually knows what they're doing. That's sort of how it compares in those regards.
Anyhow, like I said, if you get the chance to buy it by the cup then, by all means, give it a shot. It's not expensive really if you're just getting a single cup. I'd certainly not recommend buying a pound of the stuff. Also the prices quoted are a bit higher than what they were selling it at - they offered the beans for sale by the pound and I think it was $125 per pound BUT this was ten years ago or so. I think... I'm unable to recall the exact year that I went but it was somewhere around 8 to 10 years ago.
So, there's your review from me. I am aware that people's tastes are different so I'd still encourage you to consider trying it instead of relying on my review IF you were already wanting to try it and hadn't had the opportunity. If you probably weren't going to spend $12 on a cup of coffee, even if it came from poop from a Golden Retriever named Benny, then you probably should stick with your plan. It's really not very good... 'Snot very good at all.
