A café au lait is drip coffee mixed with hot milk in roughly equal parts, while a latte is espresso topped with steamed milk and a thin layer of foam. The coffee base is the real difference — one uses brewed coffee, the other uses espresso — and that changes the ratio, texture, and caffeine content all at once.
Cafe au Lait vs. Latte: The Difference at a Glance
| Cafe au Lait | Latte | |
|---|---|---|
| Coffee base | Drip/brewed coffee | Espresso |
| Ratio | ~1:1 coffee to milk | ~1:3 espresso to milk |
| Milk texture | Heated, not stretched into foam | Steamed with a thin foam cap |
| Origin | French | Italian |
| Caffeine (12oz) | ~75mg | ~64mg (single shot) |
What Is a Cafe au Lait?
“Café au lait” is French for “coffee with milk.” It’s made by combining strong drip-brewed coffee with hot milk in roughly equal parts — the milk is heated, sometimes lightly steamed, but not stretched into the thick microfoam a latte gets. The result blends smoothly rather than layering, and tastes stronger and more coffee-forward than a latte since it’s a straight 1:1 ratio rather than being diluted by a larger volume of milk.
The drink has a strong New Orleans association — Café du Monde’s version, traditionally made with coffee blended with chicory, is one of the most famous examples in the US.
What Is a Latte?
A latte starts with a shot of espresso, topped with steamed milk and finished with a thin layer of foam. The ratio runs closer to 1 part espresso to 3 parts milk, which mellows the espresso’s intensity into a milder, creamier drink than a cafe au lait’s straight coffee-and-milk blend. If you want the full technique, see our guide to frothing and steaming milk.
How the Ratio Changes the Taste
A cafe au lait’s 1:1 ratio means you’re tasting roughly as much coffee as milk, which is why it comes across stronger and more bitter-forward than a latte, even though a latte’s espresso is more concentrated per ounce. A latte’s much larger proportion of milk — and its stretched, aerated texture — is what gives it that smoother, creamier reputation. Neither is “stronger” in absolute terms; they’re just built around different ratios of the same two ingredients.
Caffeine Compared
A 12oz cafe au lait made with about 6oz of drip coffee carries roughly 75mg of caffeine, based on drip coffee’s typical ~150mg per 12oz cup. A latte made with a single shot of espresso runs closer to 64mg. Add a second shot for a doppio latte and that roughly doubles.

Which Should You Make at Home?
If you don’t own an espresso machine, cafe au lait is the easier and more accessible drink — it only needs a regular drip brewer or French press and a way to heat milk. If you already have an espresso machine or want the classic coffee-shop latte texture, a latte is worth the extra steps. Either way, both come down to good coffee and well-handled milk — see our full coffee drink types guide for where these two fit among the rest of the milk-coffee family.
Frequently Asked Questions About Cafe au Lait vs. Latte
The coffee base — a cafe au lait uses drip-brewed coffee mixed roughly 1:1 with hot milk, while a latte uses espresso topped with steamed milk at a much higher milk ratio.
A 12oz cafe au lait has slightly more caffeine (around 75mg) than a latte made with a single shot (around 64mg), since it uses a larger volume of brewed coffee rather than one concentrated shot.
Yes — that’s actually the point. A cafe au lait only needs regular drip or French press coffee and hot milk, making it the simpler drink to make at home without specialty equipment.
A latte’s much higher milk-to-coffee ratio (about 3:1) and its aerated, steamed milk texture soften the espresso’s intensity more than a cafe au lait’s straight 1:1 blend of coffee and milk.
Essentially yes — “café au lait” is literally French for “coffee with milk.” The distinguishing detail is the roughly equal ratio and that the milk is heated rather than just splashed in cold.
It’s a French tradition, though its most famous American form comes from New Orleans, where Café du Monde serves it made with coffee blended with chicory.
For the drip-coffee base a cafe au lait needs, see our French press guide if that’s your brewing method of choice. And if you’re comparing more milk-coffee drinks, see how a cappuccino stacks up against a latte too.
