This Moroccan Mint from Numi is said to contain one ingredient: organic nana mint from Morocco. It does not taste at all like the Mighty Leaf Organic Mint Mélange, which struck me as straight-up spearmint. I drank the glasses side-by-side and found very little overlap between the two. Interestingly enough, Numi describes the flavor of nana mint as similar to spearmint. What I found, in contrast, was a much more complex flavor, with an almost bread-like quality to it.
I really enjoyed the flavor and complexity of the Numi and will certainly be drinking more of this tisane, as it strikes me as unique among the many mint tea contenders.
