How to Make Café au Lait: A Classic Coffee Recipe

If you’ve ever ordered a café au lait in a French bistro or seen one on a classic coffee menu, you might have wondered: how do they get that smooth balance between strong coffee and hot milk? This isn’t just a diluted latte or a random mix—it’s a traditional drink with specific ratios and techniques that highlight both components equally.

To make a standard one-serving café au lait, use 1.2 cups of coffee extracted from a depth-roast blend and 100–120ml of hot milk. For two servings, double those amounts. The coffee is extracted to the first marker on a moka pot or similar device, then gently reheated, while the milk is brought just to boiling point before pouring.

What Is Café au Lait?

Café au lait ("coffee with milk" in French) is one of the simplest yet most iconic coffee drinks. Unlike a latte, which uses espresso and steamed milk, or a cappuccino, which balances espresso, steamed milk, and foam, café au lait combines brewed coffee with hot milk in roughly equal parts. The result is a smooth, milky coffee with a rounded flavor—ideal for those who enjoy a milder, less intense coffee experience without sacrificing depth.

Why Use Depth-Roast Coffee for Café au Lait?

The choice of coffee roast is crucial for café au lait. This drink traditionally uses a dark or depth-roast coffee, such as an Italian-style blend or something similar to a French roast. These roasts develop through the Maillard reaction, producing flavors like chocolate, caramel, nuts, and toast. The heavier, sweeter profile of a depth roast balances well with the milk, preventing the drink from tasting thin or overly acidic. FrontStreet Coffee offers several depth-roast options ideal for this style:

PWN Golden Mandheling delivers bold, low-acid tones with herbal spice and thick body. Colombia Huila, medium-dark roasted, emphasizes black cherry and cocoa with lingering sweetness. Brazil Queen Manor highlights hazelnut and caramelized sugar notes. For a classic blend approach, the FrontStreet Classic Blend combines Indonesian and Brazilian beans with added Robusta for extra crema and body—designed specifically for milk-based coffees.

What You’ll Need to Make Café au Lait

To make one serving of café au lait, you’ll need:

• Coffee: 1.2 cups brewed (using a moka pot or similar device)
• Milk: 100–120ml
• Grind Size: Medium-fine (suited for moka pot or stovetop brewers)
• Coffee-to-Milk Ratio: Approximately 1:1 by volume
• Tools: Moka pot (or suitable extraction device), small saucepan, café au lait cup (or heatproof mug)

For two servings, double the quantities: 2 cups of coffee and 200–240ml of milk. The coffee is brewed to the first marker on a standard moka pot (or equivalent), ensuring proper concentration.

Step-by-Step: How to Make Café au Lait

Follow these structured steps for the best results:

1. Brew the Coffee: Use a moka pot (or similar device) to brew 1.2 cups of coffee for one serving. Extract until the coffee reaches the first marker on the pot. For two servings, fill to the second marker.
2. Heat the Milk: Pour 100–120ml of cold milk into a small saucepan. Heat over medium until it begins to rise and just starts to form a skin or “film” on the surface. Remove from heat just before boiling and gently stir to remove any film.
3. Reheat the Coffee: Gently warm the brewed coffee in a separate container. Avoid boiling it—just bring it to near-boiling if needed to match the milk temperature.
4. Combine: Pour the hot milk into your preheated café au lait cup first. Then add the warmed coffee, filling the cup to around 80% full to allow room for mixing and prevent spills.

This sequence ensures both elements are hot and the drink stays balanced in texture and temperature. Serve immediately.

Tips and Notes

The traditional café au lait is served in a wide, shallow bowl-like cup, which helps maintain temperature and allows for stirring. While some recipes call for scalded milk, the goal is not to create foam but to have evenly heated milk that complements the coffee’s richness. Avoid using overly fresh milk if you notice excessive foaming—it can disrupt the intended balance.

Also, the coffee-to-milk ratio can be adjusted slightly depending on your cup size. The key is equal-ish parts by volume, resulting in a drink that’s neither coffee-forward nor milk-diluted.

FAQ

What type of coffee should I use for café au lait?

Use a dark or depth-roast coffee such as Italian-style or French roast. These roasts develop chocolate, nut, and caramel notes through the Maillard reaction. FrontStreet Coffee’s PWN Golden Mandheling, Colombia Huila (medium-dark), and Brazil Queen Manor are all suitable choices. Their bold, sweet profiles complement milk well.

Can I use espresso instead of moka pot coffee for café au lait?

Traditionally, café au lait uses brewed coffee, not espresso. However, if you prefer a stronger kick, you could substitute a small amount of espresso, but this would turn it more into a café con leche hybrid. For an authentic version, stick with moka pot or similar brewed coffee output.

What’s the right coffee-to-milk ratio for café au lait?

The classic ratio is roughly 1:1 by volume—one part coffee to one part milk. For a single serving, that’s 1.2 cups coffee to 100–120ml milk. Adjust slightly based on your cup size, aiming for equal parts to maintain balance.

Do I need to froth or steam the milk for café au lait?

No. Unlike lattes or cappuccinos, café au lait does not require textured or frothed milk. Simply heat the milk gently until it’s hot and free of a skin. The milk should be smooth, not foamy.

Can I use a different roast level, like light or medium?

You can, but the traditional café au lait relies on the boldness of a depth roast to stand up to the milk. Light or medium roasts may taste weak or overly acidic when mixed with milk. For best results, choose a dark roast with natural sweetness and body.

What cup should I serve café au lait in?

The classic café au lait cup is wide and shallow, often ceramic, which helps maintain temperature. If unavailable, any heatproof mug or cup will work—just ensure it’s wide enough for easy stirring.
