Served over ice
Iced coffee and cold brew are made differently. Here is the distinction.
Coffee, cooled.
This version starts with hot brewed coffee and is chilled before serving.
Brewed coffee · Ice · Milk or sweetener, optional
Mazagran, a sweetened cold coffee from Algeria, is an early example. Brew coffee hot, let it cool, and pour it over ice.
Cold brew gets its flavor from several hours of contact between cool water and coffee grounds.
Ground coffee · Cool water
Cold brewing has a long history in Japan. Steep the grounds in cool water for several hours, strain them out, and serve the coffee chilled.
