What Is Café Au Lait? The Classic French Coffee Drink

If you’ve ever sipped a creamy coffee with just the right balance of espresso and steamed milk, you might have been drinking something close to café au lait—but likely without knowing its true origin. This classic French coffee drink is loved for its simplicity and comforting warmth, especially during cold mornings. But what exactly makes it different from a latte, and how do the French really enjoy it?

Café au lait is simply a 1:1 combination of one shot of Italian espresso and one cup of hot milk, served with two spoonfuls of milk foam on top. That’s the traditional formula.

What Is Café Au Lait?

In French, café au lait literally means “coffee with milk.” It’s a smooth, velvety coffee drink where the strong taste of espresso is balanced by a generous amount of heated milk. The result is a drink that feels rich yet approachable—much like what many know as a “French-style latte.”

While similar to other milk-based coffee drinks, café au lait stands apart due to its specific French preparation style and cultural context. It’s not just a drink; it’s part of the French café experience.

The Traditional Way to Make Café Au Lait

Making café au lait is straightforward. You need:

• One shot (about 30ml) of Italian espresso
• One cup (about 150–200ml) of hot milk, heated (not frothed or steamed as in a cappuccino)
• A ratio of 1:1 coffee to milk
• Two spoonfuls of milk foam for garnish

To prepare it the classic way, hold both the espresso and the hot milk in separate containers. Pour both simultaneously into your cup to create a balanced mix. Then, add two spoonfuls of foamed milk on top. That’s it.

Why the French Love Café Au Lait

The French are the most enthusiastic fans of café au lait. It’s a staple of their breakfast routine, often enjoyed alongside a buttery croissant. Due to France’s colder northern climate, people prefer to drink it from large, handleless bowls or wide cups—sometimes called “bouillotte” cups—that let them wrap their hands around the vessel for warmth.

These oversized cups are possibly the largest used for any style of coffee worldwide. They’re practical for a reason: keeping your hands warm while sipping your morning coffee is part of the experience.

Café Au Lait vs. Other Milk Coffees

Many coffee drinkers wonder how café au lait differs from a latte or flat white. Here’s the breakdown:

• Café au lait: 1:1 espresso and hot milk, traditionally poured together, with foam on top. Served in large cups or bowls.
• Latte: Typically 1/3 espresso to 2/3 steamed milk, with a thin layer of microfoam. Often made with an espresso machine.
• Flat White: 1/3 espresso to 2/3 steamed milk, with a velvety microfoam layer, smaller in volume than a latte.

Unlike lattes and flat whites, café au lait traditionally doesn’t use textured or microfoamed milk from an espresso machine’s steam wand. The milk is simply heated, then poured alongside the espresso.

Frequently Asked Questions

What is the traditional coffee to milk ratio in café au lait?

The classic ratio is 1:1—equal parts espresso and hot milk. For example, one shot (around 30ml) of espresso is mixed with roughly the same amount of heated milk (150–200ml).

Do you steam the milk for café au lait?

No, the milk for café au lait is heated but not steamed or frothed like in a cappuccino or latte. It’s gently warmed, then poured directly into the cup along with the espresso.

Is café au lait the same as a latte?

No. While both contain espresso and milk, café au lait uses a 1:1 ratio and traditionally combines both liquids as they’re poured. Lattes usually have a higher milk-to-espresso ratio and feature steamed milk with microfoam.

What kind of cup is café au lait served in?

Traditionally, it’s served in a large, wide cup or bowl—often without handles—to help retain warmth. In France, it’s common to use your hands to hold the cup for warmth, especially in cooler weather.

Can you make café au lait at home?

Yes. All you need is a shot of espresso and a cup of hot milk. Pour them together, then top with a bit of foamed milk. No special machine is required, though an espresso maker helps.
