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. Pre-packaged iced coffee is available as a grocery item in several countries, though without ice. Iced coffee is also 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.
