What to check first

Brewer type and filter type

Frappe is distinct from other iced coffees because it doesn’t rely on traditional brewing methods like drip or pour-over. The key is the instant coffee and how it’s frothed. You won’t need a coffee maker or filters for this recipe.

While this recipe doesn’t require a traditional iced coffee maker, a good milk frother is essential for achieving that signature foam. If you don’t have one, an immersion blender or even a sturdy whisk can work in a pinch.

Water quality and temperature

While frappe uses instant coffee, the water you use still matters for flavor. Use clean, filtered water. The initial mixing of the instant coffee and sugar with a small amount of cold water is what initiates the foaming process, so cold water is essential here.

Grind size and coffee freshness

For a traditional frappe, the “coffee” is instant coffee granules (often Nescafé). This is non-negotiable for achieving the characteristic foam. Freshly ground beans won’t work for this specific recipe.

Coffee-to-water ratio

The ratio of instant coffee to water is crucial for foam development. A common starting point is 1-2 tablespoons of instant coffee to about 1/4 cup of cold water. Too much water will make it hard to achieve a thick foam.

Cleanliness/descale status

Ensure your frothing tool (milk frother, immersion blender, or even a handheld whisk) is clean. Any residue can affect the foam’s texture and flavor.

Step-by-step (brew workflow)

1. Gather your ingredients: You’ll need instant coffee (Nescafé is traditional), cold water, sugar (optional, to taste), and milk (optional, to taste).

• What “good” looks like: All ingredients are readily accessible and measured.
• Common mistake: Not having everything ready. This can lead to your foam collapsing while you scramble for ingredients.
• How to avoid: Measure everything out before you begin.

2. Add instant coffee and sugar to your glass: Choose a tall glass. Add 1-2 tablespoons of instant coffee and your desired amount of sugar.

• What “good” looks like: The coffee granules and sugar are at the bottom of the glass, ready for the water.
• Common mistake: Adding too much coffee or sugar at this stage.
• How to avoid: Start with the recommended amounts and adjust in future attempts.

3. Add a small amount of cold water: Pour about 1/4 cup of cold water into the glass.

• What “good” looks like: Just enough water to dissolve the coffee and sugar, creating a thick paste.
• Common mistake: Adding too much water. This dilutes the mixture and makes frothing difficult.
• How to avoid: Resist the urge to fill the glass; you only need a little to get started.

4. Froth the mixture: Use a handheld milk frother, immersion blender, or a whisk to vigorously whip the coffee, sugar, and water.

• What “good” looks like: A thick, stable, light brown foam that forms on top and holds its shape. This is the signature of a frappe.
• Common mistake: Not frothing long enough or vigorously enough.
• How to avoid: Continue frothing until the mixture is thick and foamy, usually 30-60 seconds with an electric frother.

5. Add ice to a serving glass: Fill a separate, larger serving glass with ice cubes.

• What “good” looks like: The glass is generously filled with ice.
• Common mistake: Not using enough ice.
• How to avoid: Be generous with the ice; it’s crucial for keeping the frappe cold and refreshing.

Fill a separate, larger serving glass with ice cubes. Using tall, clear glasses really showcases the beautiful layers of your frappe.

6. Pour the foam over the ice: Carefully spoon or pour the thick foam from the frothing glass into the serving glass over the ice.

• What “good” looks like: The foam sits atop the ice, creating a distinct layer.
• Common mistake: Pouring too quickly, which can cause the foam to dissipate.
• How to avoid: Gently guide the foam into the glass.

7. Add cold water: Pour cold water into the serving glass until it’s about two-thirds full.

• What “good” looks like: The water mixes with the foam and ice, creating the liquid base of the drink.
• Common mistake: Adding too much water, which can dilute the coffee flavor.
• How to avoid: Leave room for milk if you plan to add it.

8. Add milk (optional): If desired, add a splash of milk.

• What “good” looks like: The milk adds a creamy layer or swirls into the drink.
• Common mistake: Adding too much milk, which can mask the coffee flavor and foam texture.
• How to avoid: Start with a small amount and add more if needed.

9. Stir gently (optional): You can stir gently to combine the layers, or enjoy it with a straw to sip through the foam.

• What “good” looks like: The drink is ready to be enjoyed.
• Common mistake: Over-stirring, which can break down the foam too quickly.
• How to avoid: Stir only if you want to integrate the layers, otherwise, use a straw.

10. Serve immediately: Frappe is best enjoyed right away.

• What “good” looks like: A cold, frothy, delicious drink.
• Common mistake: Letting it sit for too long.
• How to avoid: Make it and drink it.

Common mistakes (and what happens if you ignore them)

Decision rules (simple if/then)

• If you want a very sweet drink, then add more sugar in step 2 because it dissolves best when frothed.
• If you prefer a less sweet drink, then add no sugar or just a tiny pinch because the coffee itself has a strong flavor.
• If your foam isn’t thick enough, then froth for another 30 seconds because you likely haven’t achieved sufficient aeration.
• If your foam is collapsing too quickly, then you might have used too much water initially or not frothed enough because proper foam requires a concentrated coffee base.
• If you like a creamier frappe, then add a splash of milk at the end because it will add richness without diluting the coffee flavor too much.
• If you want a stronger coffee flavor, then use 2 tablespoons of instant coffee and skip the milk because this maximizes the coffee impact.
• If you are new to making frappe, then start with 1 tablespoon of instant coffee and 1 teaspoon of sugar because this is a balanced starting point.
• If you want a very cold drink that stays cold, then use plenty of ice because it’s the primary cooling agent.
• If you want to taste the coffee more, then use less milk or no milk at all because milk can mute the coffee notes.
• If your frother is struggling to create foam, then ensure the mixture is not too watery because a concentrated base is key.
• If you find the drink too bitter, then add a little more sugar or milk because these will balance the bitterness.

FAQ

What kind of instant coffee is best for frappe?

Traditional Greek frappe is made with Nescafé instant coffee. Any good quality instant coffee granules that produce a good foam will work. Avoid instant coffee powders or liquids.

Can I use decaf instant coffee?

Yes, you can use decaf instant coffee if you want to reduce caffeine intake. The frothing process and taste will be similar, though the characteristic “kick” will be absent.

How do I get the thickest foam?

The key to thick foam is using a concentrated mixture of instant coffee, sugar, and a minimal amount of cold water, then frothing vigorously for an extended period until it’s very thick and stable.

Is it okay to add alcohol to my frappe?

While not traditional, some people enjoy adding a shot of liqueur like Kahlúa or a splash of rum for an adult twist. Add it after frothing, before adding milk or water.

Can I make frappe without a milk frother?

Yes, you can use an immersion blender or a handheld whisk. An immersion blender is often the easiest, but a vigorous whisking motion with a manual whisk can also achieve good results, though it requires more effort.

How much sugar should I use?

This is entirely to taste. A common starting point is 1-2 teaspoons of sugar per tablespoon of instant coffee. You can adjust this up or down based on your preference for sweetness.

What if I don’t have a tall glass?

You can use any glass that allows enough room for ice and frothing. A wide-mouth jar can also work, provided it’s deep enough to contain the foam.

How long does the foam last?

A well-made frappe foam can last for a good 15-20 minutes if undisturbed, especially if the drink is kept cold with plenty of ice. Stirring or adding too much liquid can break it down faster.

Can I use evaporated milk?

Evaporated milk can be used instead of regular milk for a richer, creamier texture. Add it in moderation, as it’s quite concentrated.
