Had this tea at a restaurant today, one of my favourite sushi places, though it’s not terribly authentic. I was cold so I ordered this as a hot tea. Sweetener got interesting because the restaurant was completely out of white sugar so I put some brown sugar in instead (sacreligious I know, I don’t care). It was..interesting and not awful. Which is about what I expect from restaurant bagged tea where I have no idea what any of the parameters are.
