I got this iced a while ago while I happened to be around a DAVIDs (an all too rare occurrence these days I’m afraid!) It was super refreshing but I didn’t find it all that flavourful, but considering that it is based off of watermelon, which is also mostly water, I guess that is to be expected. Refreshing and fruity, it makes a great summer tea, but I am a little disappointed by the weakness.
I find it does require a fair bit of tea to bring out the flavour, which does make it a touch expensive if you do it yourself, and weak if they brew it for you :)
