Strength of Iced Tea
I'm trying to limit my daily caffeine intake, but I love drinking iced tea. Obviously if I'm making it at home I can control the strength of the tea and thereby have an idea what the caffeine content is, but I have no control when I'm eating out. I'm talking run of the mill restaurant black iced tea (most likely Lipton or Nestea or Luzianne or generic) brewed fresh, not bottled or from a soda fountain. Does anyone know of a way of judging tea strength by color or some other method? I know that darker=stronger and lighter=weaker, but some sort of scale would be nice since tea can apparently be anywhere between 40-120 mg per 8 oz serving.
