Frappé is a coffee defined by its foam. The vigorous shaking or blending of instant coffee with a minimal amount of water traps air bubbles into a protein-and-coffee-solids matrix — a foam stable enough to persist for several minutes atop a glass of ice. This foam is the drink's signature, and its quality (density, colour, persistence) is the primary measure of a well-made frappé.
Origin and history
The frappé was invented at the Thessaloniki International Trade Fair in September 1957. Dimitris Vakondios, a Nestlé employee demonstrating a new chocolate-milk product for children, needed his break-time instant coffee but could find no hot water. He improvised by mixing Nescafé granules with cold water in a shaker — and discovered the characteristic stable foam that resulted.
The drink spread rapidly through Greek café culture, where it aligned perfectly with the long, leisurely coffee sessions of Greek social life. By the 1970s it was the default summer coffee of Greece; by the 2000s it had spread to Cyprus, Bulgaria, and Greek diaspora communities worldwide.
Technical structure
- Instant coffee: 1–2 teaspoons of Nescafé (or another soluble coffee). The instant format is non-negotiable — brewed coffee does not produce the required foam structure.
- Water: 1–2 tablespoons cold water, mixed with coffee before agitation.
- Sugar: Added before shaking — sketo (no sugar), metrio (medium), gliko (sweet).
- Agitation: Hand shaker (10–15 seconds), electric milk frother, or immersion blender.
- Ice: 4–6 cubes in a tall glass.
- Milk: Optional cold milk to taste — evaporated milk is the traditional choice.
Frappé vs. modern iced coffee drinks
Frappé predates cold brew by several decades and has no relationship to it. It is also distinct from iced Espresso (Freddo Espresso), which uses a real espresso base shaken over ice. The instant coffee base gives frappé a specific flavour profile — slightly bitter, with the particular roast character of soluble coffee — that defines the drink as much as its foam.
Best served as
In a tall glass, straw inserted, consumed slowly over 20–40 minutes as grounds continue to steep in the ice water. Ordering a frappé metrio me gala (medium sugar, with milk) is the standard Greek café default. Served year-round in Greece despite being ostensibly an iced drink.
How to prepare
- Measure 1–2 teaspoons of instant coffee and your preferred sugar (or none) into a shaker or tall cup.
- Add 30–50 ml of cold water only — not the full serving yet. The small volume concentrates the foam.
- Shake or blend vigorously for 10–15 seconds in a hand shaker, or 20–30 seconds with an electric milk frother. The mixture should turn pale and dense.
- Pour the foam into a tall glass. The foam should be thick enough to stand briefly before relaxing.
- Add ice (4–6 cubes) to the glass.
- Add cold water to fill (approximately 150–180 ml), then add milk to taste. Do not stir — the foam should float above the liquid.
- Insert a straw and serve immediately.
What to avoid
- Too much water before shaking. A large volume of water prevents proper foam formation. The pre-shake mixture should be concentrated.
- Not shaking long enough. Inadequate agitation produces a thin, flat layer of foam that dissipates within seconds. 10–15 seconds in a shaker is the minimum.
- Brewed coffee as a base. Frappé foam is a protein-and-soluble-coffee matrix that only instant coffee can produce. Brewed coffee will not foam regardless of technique.
- Skipping the ice. A lukewarm frappé without ice is simply diluted instant coffee. The ice is structural.
Tips
- Evaporated milk (unsweetened, from a tin) is the traditional Greek milk addition — it adds richness and sweetness without the volume of regular milk.
- An electric frother (the battery-operated wand type) produces a faster, more consistent foam than a shaker, especially for single servings.
- Nescafé Classic remains the most widely used brand for authentic frappé foam — the specific protein composition of Nescafé Original produces a reliable, dense foam.
- Order of assembly matters. Foam first, then ice, then liquid — not liquid first. This maintains the layered structure for longer.
