I refer to one major-marketed tea as "floor sweepings," but I think there’s such a thing as tea that’s too good to make into iced tea. Most Americans never taste such teas, though. A British vessel on which I sailed used the floor sweepings brand, so I bought teas while on shore tours. Ironic, isn’t it? Let me add water quality to your list, 1chef. Brew that tea, any tea, at home, and make a superior beverage for a fraction of what bought tea costs.
