There really isn’t much oomph to either the chocolate or the mint here, and maybe that’s indicated by the “smooth” modifier. There’s nothing offensive about this one, no odd taste at any point, but it’s just not that interesting or exciting. I have a whole 8 ounces of it, though, and while I’ll certainly work my way through it quickly enough, I don’t think that I’ll be in a hurry to replace it.
For a chocolatey tea, I adore Teavana’s Haute Chocolate. No mint, but it’s got a little kick of pepper… if that kind of spicy is your thing (as it is mine), I’d check out that one.
