An iced latte is made by combining espresso, cold milk, and ice. For a balanced 16-ounce drink, start with a double espresso made from 18 grams of coffee, produce about 36 grams of espresso, add 180 grams (about 6 fluid ounces) of cold milk, and serve it over 120–150 grams of ice. The result should taste creamy and refreshing while retaining a clear espresso flavor.
The recipe is simple, but the order of assembly, espresso strength, ice quantity, and choice of milk all affect the final drink. This guide explains how to make an iced latte at home with repeatable measurements, how to prevent it from becoming watery, and how to adjust the recipe for different cup sizes and milk preferences.
Iced Latte Recipe at a Glance
| Ingredient | Starting amount | Purpose |
|---|---|---|
| Fresh coffee | 18 g | Produces a double espresso |
| Espresso yield | 36 g | Creates a 1:2 starting brew ratio |
| Cold milk | 180 g / approximately 6 fl oz | Adds sweetness, body, and balance |
| Ice | 120–150 g | Chills the drink with enough reserve to limit rapid melting |
| Glass size | 16 fl oz / approximately 475 ml | Leaves room for ice and stirring |
Quick method: Fill a 16-ounce glass with ice, add 180 grams of cold milk, brew 36 grams of espresso, and pour the espresso over the milk. Stir before drinking. If you use syrup, dissolve or mix it into the warm espresso before assembly.
What Is an Iced Latte?
An iced latte is a cold espresso drink made with espresso, milk, and ice. Unlike a hot latte, its milk is normally poured cold rather than steamed. Unlike iced coffee, its coffee base is espresso rather than chilled drip coffee. And unlike cold brew with milk, an iced latte is prepared around a freshly extracted, concentrated shot.
Espresso matters because a small amount of concentrated coffee can remain noticeable after milk and melting ice are added. The National Coffee Association’s espresso guide describes espresso as a concentrated drink brewed under pressure and gives a 1:2 dry-coffee-to-beverage ratio as a useful starting point. That ratio works well here: 18 grams of coffee produces approximately 36 grams of espresso before milk and ice are introduced.
What You Need to Make an Iced Latte
Espresso
Use a double espresso with enough sweetness and body to stand up to cold milk. A medium or medium-dark roast is an accessible starting point, but roast labels are not rules. A lighter coffee can make a bright, fruit-forward iced latte, while a darker coffee may contribute more chocolate, caramel, or roasted flavors.
Freshly grind the coffee immediately before brewing when possible. Start with 18 grams in and 36 grams out, then adjust the grind until the shot tastes balanced. If your espresso rushes through the basket or barely drips, use the troubleshooting steps in our guide to an espresso shot running too fast or too slow.
Cold milk
Whole milk creates a full, creamy drink, while 2% milk produces a lighter result. Barista-style oat milk is a practical dairy-free option because it generally has more body than many standard plant beverages. Almond milk tends to make a lighter latte, and some products may separate when they meet hot espresso. Separation is usually a texture and appearance issue rather than a brewing failure; using cold milk and assembling the drink gradually can reduce it.
You do not need to steam milk for a classic iced latte. If you want a soft foam cap, froth a small portion of cold milk separately and spoon it on top. For a better understanding of milk texture, see our guide to steaming and texturing milk, while remembering that cold foam and steamed microfoam are different preparations.
Ice
Use enough ice to chill the entire drink quickly. A few cubes melt fast and can leave the latte cool but diluted. Starting with 120–150 grams gives a 16-ounce drink a larger cold reserve. Large, solid cubes usually melt more slowly than small or crushed ice because they expose less surface area relative to their volume.
Fresh, neutral-tasting water matters because melted ice becomes part of the recipe. If your tap water has a strong taste or odor, make ice with filtered water.
Optional sweetener
Simple syrup, maple syrup, honey, vanilla syrup, and caramel syrup can all work. Granulated sugar dissolves poorly in a cold finished drink, so stir it into the hot espresso first. Begin with 10–15 grams of syrup, taste, and increase only if needed.
How to Make an Iced Latte Step by Step
- Chill the glass if possible. A cold glass reduces the amount of work the ice must do.
- Add 120–150 grams of ice. Fill roughly half to two-thirds of a 16-ounce glass, depending on cube size.
- Pour in 180 grams of cold milk. Leave room for the espresso and for stirring without spilling.
- Prepare the espresso. Grind 18 grams of coffee, distribute and tamp it evenly, then brew approximately 36 grams of espresso. A 20–30 second contact time is a useful diagnostic range, but flavor and even extraction matter more than hitting one exact number.
- Add sweetener while the espresso is warm. Stir until fully combined before pouring it into the glass.
- Pour the espresso over the milk and ice. Pour slowly if you want a visible layered effect.
- Stir before drinking. The layers look appealing, but stirring distributes the espresso and gives a more consistent flavor from the first sip to the last.
A machine with an integrated grinder and scales can make the espresso portion easier to repeat. The Meraki Espresso Machine, for example, measures both coffee dose and espresso yield, so the 18-gram input and 36-gram output can be tracked without a separate scale. These measurements do not replace tasting, but they help keep the base recipe stable while you adjust one variable at a time.
Should You Pour Espresso or Milk First?
For an easy, visually layered iced latte, add ice and milk first, then pour in the espresso. The cold milk begins cooling the espresso immediately, and the darker coffee remains visible near the top until the drink is stirred.
You can also mix the espresso and milk before pouring them over fresh ice. This produces an evenly combined drink and limits the time that very hot espresso sits against a few cubes. Neither order is universally “correct.” Use milk first for presentation and convenience; pre-mix the espresso and milk when you prioritize uniform temperature and flavor.
Avoid letting the espresso sit uncovered for a long time in an attempt to cool it completely. Its aroma and temperature will change as it rests. Instead, prepare the glass before pulling the shot, then assemble promptly.
How to Keep an Iced Latte from Tasting Watery
Start with a balanced espresso
Milk and ice cannot correct a poorly extracted shot. If the espresso is sharply sour, thin, or hollow, grind finer while keeping dose and yield stable. If it is harsh, dry, or excessively bitter and runs slowly, grind coarser. Uneven puck preparation can also create weak and bitter flavors in the same cup; our guide to espresso channeling explains the signs and common causes.
Do not solve every problem by adding more coffee
A second double shot can overpower the milk and substantially change the drink. First check whether the original shot is properly extracted. If it tastes balanced on its own but disappears in the latte, reduce the milk from 180 grams to 150 grams or use a slightly shorter espresso yield, such as 32–34 grams from an 18-gram dose.
Use more ice, not less
This sounds counterintuitive, but a glass with plenty of cold ice can chill the drink faster and retain unmelted cubes. A small amount of ice absorbs heat, melts, and leaves no reserve. Begin with cold milk, a cool glass, and a generous quantity of solid cubes.
Choose coffee that remains clear in milk
Chocolate, nut, caramel, and deeper fruit notes are often easy to recognize in milk, but any well-roasted coffee can work. Explore the available coffee beans by flavor preference rather than assuming that only a product labeled “espresso roast” can be used.
Iced Latte Ratios for Different Glass Sizes
| Glass size | Espresso | Cold milk | Ice |
|---|---|---|---|
| 12 fl oz / 355 ml | 30–36 g | 120–150 g | 90–120 g |
| 16 fl oz / 475 ml | 36 g | 180 g | 120–150 g |
| 20 fl oz / 590 ml | 36–54 g | 220–250 g | 160–200 g |
These quantities are starting points rather than formal drink standards. Ice shape changes how much will fit in a glass, and milk preference changes perceived strength. Keep the espresso recipe consistent, measure the milk, and adjust one component on the next drink.
Easy Iced Latte Variations
Iced vanilla latte
Stir 10–15 grams of vanilla syrup into the espresso, then pour it over the milk and ice. Reduce the syrup if your milk is already noticeably sweet.
Iced caramel latte
Mix 10–15 grams of caramel syrup with the warm espresso. A decorative drizzle adds sweetness quickly, so taste the mixed drink before adding more.
Brown sugar oat milk iced latte
Dissolve 8–12 grams of brown sugar in the espresso and add a small pinch of cinnamon if desired. Pour over ice and 180 grams of barista-style oat milk.
Unsweetened iced latte
Use only espresso, milk, and ice. If it tastes flat without syrup, improve the espresso or try a naturally sweeter-tasting milk before adding sugar.
Iced Latte vs Iced Coffee vs Cold Brew
| Drink | Coffee base | Typical milk role | General character |
|---|---|---|---|
| Iced latte | Espresso | Core ingredient | Creamy and espresso-forward |
| Iced coffee | Chilled or ice-brewed filter coffee | Optional | Lighter body and longer coffee flavor |
| Cold brew | Coffee extracted in cool water over hours | Optional | Round, smooth, and brew-dependent |

Frequently Asked Questions
What is the best ratio for an iced latte?
Start with 36 grams of espresso and 180 grams of milk, which is an espresso-to-milk ratio of approximately 1:5 by weight before ice dilution. Use 120–150 grams of ice in a 16-ounce glass. For a stronger drink, reduce the milk to 150 grams before adding another shot.
How many shots of espresso are in an iced latte?
A 16-ounce iced latte commonly works well with a double espresso. Shot terminology varies by basket and café, so weight is more reliable: use approximately 18 grams of dry coffee to produce 36 grams of espresso.
Do you need to cool espresso before making an iced latte?
No. Prepare the cold milk and ice first, then add the freshly brewed espresso and stir. If minimizing immediate ice melt is your priority, mix the espresso with the cold milk before pouring the mixture over fresh ice.
Can you make an iced latte without an espresso machine?
You can make a similar milk drink with concentrated AeroPress or moka pot coffee, but technically the base is not machine-brewed espresso. Use a small amount of strong coffee so the flavor does not disappear in the milk, then adjust the label and expectations accordingly.
Can you froth cold milk for an iced latte?
Yes. Cold foam is optional and changes the texture rather than defining the drink. Froth a small portion of cold milk separately, assemble the latte, and add the foam last.
Why does my iced latte taste bitter?
The espresso may be over-extracted, the roast may be darker than you prefer, or the shot may have extracted unevenly. Taste the espresso before adding milk. If it runs slowly and tastes dry or harsh, try a slightly coarser grind while keeping dose and yield unchanged.
Final Takeaway
To make a balanced iced latte at home, start with 18 grams of coffee, brew 36 grams of espresso, and combine it with 180 grams of cold milk and 120–150 grams of ice in a 16-ounce glass. Prepare the glass first, mix sweetener into the warm espresso, and stir the completed drink before tasting. Once the base recipe is repeatable, adjust the milk or espresso yield—not several variables at once—to create the strength and texture you prefer.
