How to Make a Latte with Proper Espresso and Milk Ratio

If you’ve ever ordered a latte and ended up with something too milky, bitter, or just plain weak, you’re not alone. Many people assume a latte is simply espresso with a lot of milk—but there’s more precision to it. The balance between espresso strength, milk volume, and milk texture makes or breaks your cup. Here’s how to make a proper latte step by step.

To make a classic latte, use a double shot of espresso (about 30–40ml) and add 180–240ml of steamed milk, with 6–7mm of microfoam on top—this keeps the coffee-to-milk ratio around 1:6 to 1:8. The result should be creamy but still coffee-forward.

What Exactly Is a Latte?

A latte, short for caffe latte, is an Italian-style coffee drink made with a shot (or more) of espresso and steamed milk. The name literally means “coffee with milk.” What sets a latte apart from similar drinks like a cappuccino is the higher milk volume and smoother microfoam, which creates a velvety texture and allows for beautiful latte art.

Unlike a macchiato or flat white, a latte has a larger overall volume—usually served in a 350ml glass or ceramic mug—with a thinner layer of foam on top. The bulk of the drink is steamed milk, which tempers the intensity of the espresso.

Espresso-to-Milk Ratio: Why It Matters

Many casual coffee drinkers assume an espresso is too strong and opt for milk-heavy alternatives like a latte or cappuccino. But here’s the twist: a standard espresso shot uses 7–18g of coffee to produce about 30ml of concentrated brew. A latte, which may seem diluted, actually contains more espresso—typically a double shot (around 60ml total brew)—making it richer than you think.

The typical latte is built with a 1:3 to 1:5 espresso-to-steamed milk ratio. That means for every part espresso, you’re adding three to five parts milk. Add another 6–7mm of foam, and your total drink could be around 1:6 to 1:8 coffee-to-total liquid ratio. This ratio ensures the coffee remains present without overwhelming the drinker.

How to Make a Classic Latte (Step-by-Step)

Making a latte involves three key skills: pulling a quality espresso shot, steaming milk to the right texture, and pouring to integrate everything smoothly (and optionally, creating latte art).

1. Pull the Espresso Shot

Start with a double shot of espresso using around 20g of finely ground coffee. Aim for a 40ml yield in 25–30 seconds. This shot should have a rich, reddish-brown crema about 3mm thick—indicating proper extraction and freshness.

For best results, use a blend or single origin roasted medium to medium-dark for optimal body and crema. The espresso should taste balanced, not overly sour or bitter.

2. Steam and Texture the Milk

Pour cold milk (preferably whole milk for best texture) into a steaming pitcher. Start steaming when the milk is around 5–10°C. Position the steam wand just below the surface to create a whirlpool and introduce air for the foam. Once the milk expands slightly and the pitcher gets warm to the touch, sink the wand deeper to heat the milk without creating large bubbles.

Stop steaming when the milk reaches 55–60°C. You want a smooth, glossy microfoam with tiny, uniform bubbles—ideal for pouring latte art. The total milk volume should increase by about 20–30%, leaving you with about 180–240ml of steamed milk plus foam.

3. Assemble the Latte

Pour about ¼ of the espresso directly into your serving cup. Then add steamed milk until the cup is about ¾ full. Finally, spoon the microfoam on top to fill the cup completely. For a cleaner look or latte art, tilt the cup and pour the milk through the foam to integrate it smoothly.

An Alternative Latte Recipe Using Instant Coffee

If you're not set up for espresso, you can still make a latte-like drink using instant coffee. Here's an alternative method using common household ingredients:

Ingredients:

• 20ml sugar syrup
• 100ml hot water
• 1 cup (about 240ml) fresh milk
• 1–2 sachets of instant coffee (e.g. Nestlé Pure)

Steps:

1. Brew the instant coffee using hot water according to package instructions.
2. Heat the milk to 60–65°C, then pour it into a milk frother and texture it into fine microfoam. Tap the pitcher to remove large bubbles.
3. In your cup, add the sugar syrup and 180ml of the steamed milk (from the bottom of the pitcher, avoiding large foam).
4. Stir gently to combine, then spoon the remaining foam on top until the cup is 6–7/10 full.
5. Pour the brewed instant coffee slowly over the back of a spoon to float it on top, or simply stir it in.

This version follows a coffee:milk:foam ratio of approximately 1:8:1, resulting in a milder, milk-forward drink. While not a true espresso-based latte, it offers a similar experience with less equipment.

Latte Art: Getting That Signature Look

The hallmark of a well-made latte is its silky microfoam and optional latte art. To pour basic latte art like a heart or tulip, you’ll need a steady hand, the right milk texture, and practice.

The key is pouring from a height, then sinking the spout into the cup to create patterns as you finish. The foundational step is achieving a “golden circle”—where the crema and foam blend smoothly for a seamless visual effect.

Frequently Asked Questions

What’s the ideal espresso-to-milk ratio for a latte?

A traditional latte uses a 1:3 to 1:5 espresso-to-steamed milk ratio, meaning for every part espresso, you add three to five parts milk. With a double shot (around 60ml), this results in about 180–300ml of milk, depending on your preferred strength. Including foam, the total ratio often ends up around 1:6 to 1:8.

How much milk is in a standard latte?

A standard latte typically contains 180–240ml of steamed milk, plus 6–7mm of microfoam on top. In total, the milk component (including foam) usually makes up 70–80% of the drink, with the rest being espresso.

Can I make a latte without an espresso machine?

Yes. You can use instant coffee or a Moka pot to create a strong coffee base, then add steamed milk and foam. While it won’t have the same crema or depth as espresso, it can still produce a latte-like drink with the right milk texture and ratios.

What’s the best milk temperature for steaming?

The optimal temperature for steaming milk for a latte is between 55–60°C. Going beyond 65°C can scald the milk, ruining both the taste and the ability to create stable microfoam.

Why is crema important in a latte?

Crema is the golden-brown foam on top of a well-extracted espresso. It adds richness, aroma, and visual appeal. In a latte, while the crema gets mixed with milk, starting with a good crema ensures your espresso is fresh and properly extracted, which impacts the final flavor.
