Milk tea comes in a transparent, squarish plastic bottle. It’s an opaque tan liquid not too different from the milk coffee that you can find in America. But it’s better because it’s tea. I’m not sure what kind of tea (or what kind of milk, for that matter), but it’s very very good; I typically had half of a small bottle at breakfast and then stuck the rest in my backpack for an early afternoon refresher. It’s sweet, and I don’t usually sweeten my tea, but it works with milk tea.
My favorite milk tea is made by Kirin. It’s far more addictive than the caffeine alone should account for. I think they put crack in it or something.
