How Do You Make an Iced Latte?
Brew a double espresso, combine it with cold milk and ice, then stir before tasting. This measured recipe uses 36 g finished espresso, 150 g cold milk and 120 g ice in a roughly 350 ml glass. The espresso-to-milk ratio is about 1:4.2 by mass; ice is tracked separately because it changes the drink as it melts.
Key Takeaways
- 1Use a double espresso so the coffee remains clear after milk and melting ice are added.
- 2Start with 36 g finished espresso, 150 g cold milk and 120 g ice.
- 3Track ice separately from the espresso-to-milk ratio because meltwater changes strength over time.
- 4Leave 20-30 ml headspace and stir before judging the balance.

What Is an Iced Latte?
An iced latte is espresso served with cold milk and ice. Unlike an iced Americano, it uses milk rather than water as the main diluent. Unlike cold brew coffee, the coffee is brewed hot under pressure immediately before assembly.
The drink is simple, but its balance changes as the ice melts. Measuring espresso, milk and ice independently makes the first sip repeatable and shows which variable to adjust next time.
Measured Iced Latte Recipe
Use a glass with about 350 ml usable capacity and leave at least 20-30 ml headspace. A glass filled to the rim is difficult to stir and more likely to spill as the ice shifts.
Recipe Snapshot
- Yield: 1 iced latte
- Prep time: 3 minutes
- Cook time: 1 minute
- Total time: 4 minutes
- Glass: About 350 ml usable capacity
- Starting ratio: About 1:4.2 finished espresso to milk by mass; ice measured separately
Ingredients
- 18 g coffee, ground for espresso
- 150 g cold milk
- 120 g ice
Equipment
- Espresso machine and grinder
- Scale
- 350 ml glass
- Long spoon
Method
- Brew 18 g ground coffee to 36 g finished espresso.
- Pour 150 g cold milk into a 350 ml glass with at least 20-30 ml headspace.
- Add 120 g ice to the milk.
- Pour the espresso over the ice and milk.
- Stir thoroughly before tasting so temperature and dilution are even.
Iced Latte Ratio Guide
This table scrolls horizontally on smaller screens.
| Style | Finished Espresso | Cold Milk | Approximate Ratio | Result |
|---|---|---|---|---|
| Coffee-forward | 36 g | 120 g | 1:3.3 | More espresso definition |
| Balanced starting point | 36 g | 150 g | 1:4.2 | Creamy but still coffee-led |
| Mild | 36 g | 180 g | 1:5 | Softer and milk-forward |
Keep the ice at 120 g while testing these rows. If milk and ice both change, it becomes difficult to identify why the cup improved or weakened.
Best Assembly Order
Milk first, then ice, then espresso is practical at home: the glass is chilled before the espresso arrives, and the visible swirl makes it easy to see when the drink has been stirred evenly. Espresso-first also works, but hot espresso sitting against an empty glass or a small amount of ice can melt more ice before the milk is added.
Layering is visual, not a quality test. The drink should be stirred before serving so temperature, strength and sweetness are consistent.
Milk, Cold Foam and Sweeteners
Whole milk creates the roundest texture. Two-percent milk gives a lighter result, and barista-style oat or soy drinks are practical dairy-free options. Product sweetness and stability vary, so the best milk for coffee guide can help with selection.
Cold foam is optional. If you add it, keep enough glass headspace and reduce the liquid milk slightly. Dissolve syrups in the hot espresso before assembly; thick sweeteners are harder to disperse once the drink is cold.
How to Make an Iced Latte Without an Espresso Machine
These coffee bases are not equally concentrated, so adjust each one separately. Start with 50 g short AeroPress or strong moka pot coffee and 110 g cold milk. For cold brew concentrate made at about 1:4 to 1:6 by input mass, start with 60 g concentrate and 120 g milk. Add 120 g ice, stir, then add milk in 10-15 g increments until the coffee and milk taste balanced. The result is a latte-style alternative rather than a conventional espresso-based iced latte.
Iced Latte vs. Similar Cold Drinks

| Drink | Coffee Base | Main Diluent | Typical Character |
|---|---|---|---|
| Iced latte | Espresso | Cold milk | Creamy and milk-forward |
| Japanese iced coffee | Hot-brewed filter coffee chilled over ice | Optional milk | Lighter body, brew-dependent |
| Iced Americano | Espresso | Cold water | Clean and coffee-forward |
| Iced flat white | Espresso | Less cold milk | More concentrated than an iced latte |
| Cold brew latte | Cold brew concentrate | Cold milk | Smooth, low-temperature extraction character |
Iced Latte Troubleshooting
This table scrolls horizontally on smaller screens.
| Problem | Likely Cause | Fix |
|---|---|---|
| Weak after a few minutes | Fast ice melt or too much milk | Use colder ingredients, larger cubes or 120 g milk |
| Too intense | Too little milk | Increase milk in 15-30 g steps |
| Watery from the start | Wet, partially melted ice | Use fresh, fully frozen cubes and weigh them quickly |
| Sweetener sits at the bottom | Added directly to the cold drink | Dissolve it in hot espresso first |
| Drink is uneven | Served without stirring | Stir until the color and temperature are uniform |
| Glass overflows | No headspace | Use a larger glass or reduce milk before reducing ice |
Calories, Caffeine and Allergens
The unsweetened recipe made with 36 g espresso and 150 g whole milk is estimated as follows. This calculation uses USDA reference values for whole milk and espresso.
| Nutrition per house serving | Estimated amount |
|---|---|
| Calories | 95 |
| Carbohydrate | 7.8 g |
| Total sugar | 7.6 g |
| Added sugar | 0 g |
| Protein | 4.8 g |
| Total fat | 4.9 g |
| Saturated fat | 2.8 g |
| Fiber | 0 g |
| Sodium | About 70 mg |
Melting ice adds water but no calories. Syrups, cold foam and toppings must be counted separately, and milk labels vary by product.
Caffeine comes from the espresso, not the milk, ice or finished glass size. In one controlled study, all-Arabica double-shot extractions made with a dose comparable to this 18 g recipe contained roughly 152-174 mg in regular shots, while longer extractions approached 200 mg. Those are planning examples, not a measurement of this house recipe; species, blend, dose and extraction can move the result outside that range. See the Espresso caffeine reference note for the separate USDA serving proxy.
Dairy milk is a major allergen in the United States. Plant-based products may contain soy or tree nuts, and cafe equipment can introduce cross-contact.
