The “blue” part is the novelty of this tea, but why I really enjoy it is that Adagio saw fit not to add any hibiscus (I don’t know why that is perceived as a necessity with fruit teas). It is just gently lemony and blueberry-y without tartness. Another reviewer suggests a longer steep, and I agree—I got impatient last night and pulled it a little too soon. It was still a good nightcap.
Hallelujah for the NO HIBISCUS part. I want some fruity summer tea and they all seem to have it! Just ordered some promising prospects, though!
