I only really drink types of green tea, sometimes other herbal teas if there's nothing else.

I don't take caffeine, but I can enjoy the tiniest of caffeine that's found in green tea without my stomach twisting in protest. I love all types of green tea, all except ones that has a citrus flavour to it because that's just nasty.

I've yet to find hydrangea tea, though, despite looking everywhere to try it.
