Iced tea (or ice tea) is a form of cold tea. Though usually served in a glass with ice, it can refer to any tea that has been chilled or cooled. It may be sweetened with sugar, syrup and/or apple slices. Iced tea is also a popular packaged drink and can be mixed with flavored syrup, with multiple common flavors including lemon, raspberry, lime, passion fruit, peach, orange, strawberry, and cherry. While most iced teas get their flavor from tea leaves (Camellia sinensis), herbal teas are sometimes served cold and referred to as iced tea. Iced tea is sometimes made by a particularly-long steeping of tea leaves at a lower temperature (one hour in the sun versus 5 minutes at 180–212 °F/80–100 °C), which is known as sun tea.
