Iced coffee is a type of coffee beverage served chilled, brewed variously with the fundamental division being cold brew – brewing the coffee cold, yielding a different flavour, and not requiring cooling – or brewing normally (hot) and then cooling, generally by simply pouring over ice or into ice cold milk. In hot brewing, sweeteners and flavourings are often mixed into the hot coffee before cooling, due to faster dissolution in hot water. Alternatively, syrup (sugar pre-dissolved in water) may be used, particularly gum syrup. 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. Regardless of brewing method, iced coffee is generally brewed at a higher strength than normal coffee, due to the dilution caused by the ice.
