Sweet tea, also known as sweet iced tea, is a popular style of iced tea commonly consumed in countries such as the United States (especially the South) and Indonesia. Sweet tea is most commonly made by adding sugar or simple syrup to black tea either while the tea is brewing or still hot, although artificial sweeteners are also frequently used. Sweet tea is almost always served ice cold. It may sometimes be flavored, most commonly with lemon but also with peach, raspberry, or mint. The drink is sometimes tempered with baking soda to reduce its acidity.
