I make my own iced tea. Boil up a big pot of water, drop the tea bags in, let steep for five minutes, dump out the tea bags, then put it in one of those gallon bottles with a spigot near the bottom and stick it in the refrigerator.
Then pour it into a glass over ice with a splash of grape juice. Not lemon. That's how you make iced tea.
"Refreshing" doesn't even begin to describe it.
