Frappe is a foam covered iced coffee drink usually made with spray-dried instant coffee and evap milk.
Its invention dates back to the 1957 International Trade Fair in Thessaloniki. A representative of the Nestlé company, Yannis Dritsas, was exhibiting a new product for children, a chocolate beverage produced instantly by mixing it with milk and shaking it in a shaker. Dritsas' employee Dimitris Vakondios was looking for a way to have his usual instant coffee during his break but he could not find any hot water, so he mixed the coffee with cold water in a shaker. This improvised drink has been called the national coffee of Greece, and is available at virtually all Greek cafés.
