Iced coffee is a coffee beverage served cold. It may be prepared either by brewing coffee normally (i.e. carafe, French press, etc.) and then serving it over ice or in cold milk or by brewing the coffee cold. In hot brewing, sweeteners and flavoring may be added before cooling, as they dissolve faster. Iced coffee can also be sweetened with pre-dissolved sugar in water. Iced coffee is regularly available in most coffee shops. Iced coffee is generally brewed at a higher strength than normal coffee, given that it is diluted by the melting ice. In Australia, "iced coffee" is a common term for packaged coffee-flavored and sweetened milk beverage. History Mazagran, a cold, sweetened coffee beverage that originated in Algeria circa 1840, has been described by locals as "the original iced coffee". It was prepared with coffee syrup and cold water. Frozen coffee beverages, similar to slush, are documented in the 19th century. Similar is the Italian granita al caffè. Coffee brewed then chilled with ice, called "iced coffee", appears in menus and recipes in the late 19th century. Iced coffee was popularized by a marketing campaign of the Joint Coffee Trade Publicity Committee of the United States in 1920. Much later, it was marketed by chain outlets like Burger King, Dunkin' Donuts and Starbucks. Variations by country Australia In Australia, iced coffee may include syrup, cream, cocoa powder or coffee beans. The café style is something like an unblended milkshake, and may be made from espresso coffee or only coffee flavoring, such as that sold commercially since the late 19th century in the form of a syrup, an example of which is Bushells Coffee And Chicory Essence. The packaged beverage is a different product altogether. In South Australia, Farmers Union Iced Coffee has outsold Coca-Cola and is one of the state's biggest brands.
