This is not good quality tea or even as good as tea you get at a fast food restaurant. I bought this at a upscale grocery store in my area so surprised the taste was "funky" like a bad taste to it I couldn't quite put my  finger on.  A friend of mine came by an saw what was left of it in my fridge, which was most the bottle, and I told them go ahead an have it if they liked it, as I didn't.  They took two sips and made the same conclusion, they didn't like it either.  They said it tasted like it had been made with low quality water, as in unfiltered - even dirty tap water!  Maybe that was the unpleasant under taste I could not identify?
