I am inclined to refrain from giving this one a numerical rating, as it tastes like exactly what it promises to- sweet potato pie. I can really taste the sweet potatoes in it, and even the marshmallow. But it turns out this is too sweet for me (don’t laugh, it was a kind donation by silvermage). I don’t even put sugar or any sweetener in my tea, so there’s that to take into account- if you generally sweeten your black tea, you might be in for a treat here.
Actually, I have to say that this is one of the Adagio blends that best delivers on its description, of those I’ve tried. I’m going to keep at it and see if I can develop a taste for it, as I don’t have much tea with me here in Japanese-immersion-camp land.
