Wow...I haven't tried just plain Rooibos tea. I'm not sure I'd dig drinking pickle juice. I don't care how much it helped my acne I couldn't drink it.
I tried a blend of rooibos tea at a gourmet tea shop (WAY too expensive) and the get gorgeous. Both of them tasted very good. I don't add sugar to the GG because I think it has a hint of sweetness from the orange peel. Well, I don't like the taste of Chamomille tea at all but my friends love it!!! Anyway, to answer your question, the rooibos teas that I have tried don't taste like pickles...at least not to me.
