Iced tea had started to appear in the USA during the 1860s. Seen as a novelty at first, during the 1870s it became quite widespread.
Though usually served in a glass with ice, it can refer to any tea that has been chilled or cooled. It may be sweetened. Iced tea is also a popular packaged drink.
It can be mixed with flavored syrup, with multiple common flavors including lemon, raspberry, lime, passion fruit, peach, orange, strawberry, and cherry.
Iced tea is traditionally served with lemon slice used as a garnish, which is often placed on the rim of the glass.
