A Frappuccino is the Starbucks compromise between the original Greek coffee frappé and a milkshake, using a recipe they acquired 26 years ago. The only consistent commonalities between a frappé and a Frappuccino is that both are cold blended drinks with foam. A Greek frappé is always made of instant coffee, ice, and cold water, with sugar optional. The Frappuccino recipe may or may not contain coffee and is always sweet.
