Iced coffee

Iced coffee is a coffee beverage served cold. It may be prepared either by brewing coffee normally 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. Iced coffee is made by brewing hot coffee, and pouring it over ice; Cold brew coffee is made without heat by steeping coffee grounds into lukewarm water. 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.
