Black Currant tea is sweet on it's own, so if you like Rosehip without sweetener, Black Currant might be okay without anything added :)
Tea without Milk/Cream? NOooOOOoooooo! (JK! .... I've been known to have my tea without anything in it except splenda)
Black Currant Tea is rich and fruity and is excellent with a bit of sweetener/sugar/honey/whatever. I don't think it handles milk very well, though. I can't remember. Been 3 years since I found a package! LOL! It smells absolutely stunning. I could sit snorting the bags all day, LOL!
