Don't tell the Teavana-haters I said this, but . . .
You should try some green rooibos from Teavana. It is very different than the red rooibos blends from Adagio. Personally, I can hardly even drink Adagio's red rooibos teas, and they don't sell green.
Also, Teavana also has some teas with green and red rooibos mixed, which are also pretty good.
I would recommend Teavana's Rooibos Tropica, as opposed to Adagio's Rooibos Tropics, as a starter rooibos tea. It is very good, and blends well with almost any tea you would ever want to put it with!
