Let me get one thing straight. This juice is really something else and I, not unlike many others, would love to give it a higher review but unfortunately, I can't. The juice comes with a nice package and the kind of attention to detail that you'd expect at this price range. The colour really is dark and the smell very potent. In my Joyetech Delta 16 with 1.6 Ohm attached to a Spinner 2 the vapor production is as good as you'd want it to be. The taste is, to my distaste, very powerful.
You get all the sensations mentioned in the description, Truffle, (old) coffee and a nondescript sweetness //: EDIT* The sweetness is reminiscent of a full bodied dark bread that you suckle on and play with in your mouth. Bread, especially dark bread like pumpernickel, has a lot of long chain sugar molecules that are broken down chemically in your mouth to regular sugar. On the tongue you have the same lasting sensation with this. Personally, I would have preferred more of a milk coffee taste, but that is not what you're getting here. I could have imagined a less powerful mixture of the flavours with a little spicy orange to counterbalance the coffee and give it an interesting twist.
In conclusion: If you like Truffle and cold or at least black coffee, dark bread and powerful juices, grab this one. It stands for everything dark and rich without shenanigans, without cream, without milk. Otherwise look to another of the truly great juices from Five Pawns. This is not a bad juice but I can not imagine many would actually like this juice. Perhaps every once in a while, but there are so many other good juices that, for me, this doesn't win any battle
