I generally don't drink tea, but regularly drink hot coffee gone cold, and occasionally iced coffee. I hasten to add that if I had milk in my coffee, I would, in all probability, drink it neither iced nor gone-cold.
(Softers, Graham III) No, I meant tea gone cold. Great! Coffee gone cold is just as good. I make a virtue of necessity because having brewed it I get on with doing something and forget about the drink.
