Greek frappe, another whipped coffee concoction, is super similar to Dalgona coffee and actually dates back to 1957 Greece. Dimitris Vakondios, a Nescafe representative, was at the International Trade Fair in the Greek city of Thessaloniki and accidentally created the drink by mixing coffee + water in a shaker. What a happy accident! The biggest differences between a Greek frappe and Dalgona coffee are the milk base and the amount of water used. While Dalgona coffee calls for equal parts water, instant coffee, and sugar whipped and poured over milk, Greek frappes are made with cold water + ice poured into the finished instant coffee, sugar, water whip with an optional splash of milk to finish.
