Eh, I’m not impressed. The “blackberry” tastes and smells overwhelmingly fake and it’s more like a fruity-berry flavour with some hibiscus thrown in than anything that resembles blackberries (which I love eating). The tea base is bland and close to flavourless; this could almost be a tisane for all the role it plays in this tea.
It’s not a godaweful tea I guess, but not one I’m going to be running out to go buy.
