These teas can resemble virtually any flavor imaginable.
Back when I used honey in tea (prior to diagnosis of diabetes) I used to put it in afterwards. I don't know if the tea would completely dissolve the honey if it was put in a cold cup. But now I use splenda in my tea instead of honey. I don't really think it matters much either way, but I'm still a newb to tea so maybe someone else will chime in with an answer.
Honey contains fructose, glucose, and a little sucrose, while sugar is pure sucrose. When it hits your mouth, fructose is sweeter than sucrose, which is why honey tastes sweeter and thus you’ll probably use less of it, making the calorie difference a wash.
