The obvious comparison (given that many reviewers have mentioned it, and it was my first thought as well) is to Harney’s Hot Cinnamon Spice black tea . Which personally, I find is like getting kicked in the face with cinnamon (which sometimes I am in the mood for…but usually not).
This one is slightly less cinnamony, and it does have a little kick to it, but from the chili peppers! I never imagined having a “hot,” in the chili peppers sense, tea but … I like it :) The heat comes right at the end, and it’s pretty mild. If you enjoy Mexican hot chocolate, which usually has cinnamon and some kind of chili, then you should try Hot Lips!
I should add that sometimes I find that green tea tastes like soap…this one doesn’t :)
