American here. I drink tea hot and iced, every day. I prefer black, with no milk or sugar. I can't think of the last time I saw anyone put milk in their tea. Sometimes sugar or honey (both seem to be equally popular here), but never milk.
I'll have to join with the others here who don't group tisanes into the category of 'tea.' I don't like when I choose tea from a list of beverages, just to be presented with lots of herbals and no real tea whatsoever. I do like a pure peppermint infusion, but not when I'm expecting tea.
I boil water in an electric kettle that sits out on my counter, then pour into a teapot with loose leaf tea, and I like nearly any kind of black tea I've tried. Green, white, oolong are all nice enough, but black is the best. I suppose it is a faux pas that I let the tea steep waaaay too long before my 3rd & later cups and it gets awfully strong. I actually kind of like that, though!
