Cafe Au Lait Vs Flat White

5 Key Differences Between Cafe Au Lait Vs Flat White

1. Origin

Now:

The Cafe Au Lait coffee drink originated in France in early 1600. This is before the invention of the Caffè latte (Coffee with milk) by the Italians.

The French word Cafe Au Lait also means “Coffee with milk” in English just like the Italian Caffè latte.

Unlike the Cafe Au Lait, which is more than 400 years old, the Flat White is a recent invention. Flat White’s origin is contested, but it originated in either Australia or New Zealand in the mid-1980s.

Most scholars point out that the drink originated in Australia but was perfected in New Zealand. 

Note:

Since Café au lait is coffee and milk, the drink has different names.

  • Poland – Kawa biala
  • Brazil – Café com leite
  • Germany – Milchkaffee
  • Portugal – Café com leite
  • Hungary – Tejeskávé
  • Dutch – Koffie verkeerd

Sometimes:

Coffee Shops have a different name for the Cafe Au Lait. For instance, Starbucks’ Cafe Au Lait is called Caffe Misto.

There are also variations of Cafe Au Lait such as the New Orleans version that contains chicory.

2. Ingredients

Traditionally, Cafe Au Lait is made with brewed coffee (not espresso) and milk. This can be French Press coffee, Drip coffee, or Moka coffee.

Now:

The reason why Cafe Au Lait is traditionally made with brewed coffee is that during its invention, there were no espresso machines. Today, however, some cafes use espresso to make a Cafe Au Lait.

The milk can be steamed or warmed over a stove.

Flat White, on the other hand, is an espresso drink made with espresso shots or ristretto shots, and microfoam. The velvety smooth microfoam is the signature feature of this drink.

Since you don’t require an espresso machine and a milk frother to make a Cafe Au Lait, it’s one of the easiest coffee drinks to make as long as you know how to brew coffee.

3. Taste

 Now:

Unlike Flat white, which has espresso as the base, Cafe Au Lait is prepared with either Drip coffee, French Press coffee, Moka Pot coffee, or sometimes espresso.

Since the drink contains equal parts of the base coffee and steamed or hot milk, the coffee taste is toned down and the drink gets a little bit sweet.

The specific taste will depend on the base coffee, beans, and roast.

Since a flat typically contains 2 shots of espresso, it has a strong espresso flavor. The steamed milk injects some sweetness and texture.

4. Serving

Get this:

The French Cafe Au Lait is traditionally served in a wide-mouth porcelain bowl. This design allowed the person drinking to dip their favorite pastries, which are commonly baguettes or croissants.

Since the bowl has no handles, it is held with both hands, helping to keep the hands warm in the morning. However, it is not uncommon to find Cafe Au Lait being served in cups.

Note:

The standard serving size of a Cafe Au Lait is 13 -16 Oz.

Fun Fact:

Cafe Au Lait bowls are favorite collector items among coffee connoisseurs.

While the standard Flat White serving is 5-6 Oz that is 2 shots of espresso and 4 ounces of microfoam, some coffee shops sell larger sizes of up to 20 Oz.

Flat white is served in ceramic cappuccino cups.

5. Nutritional Value

Look:

Since an espresso shot contains an average of 63 mg of caffeine, the standard Flat White serving containing 2 shots of espresso has about 126 mg of caffeine.

Conversely:

A standard 16 Oz Cafe Au Lait serving containing 8 ounces of coffee and 8 ounces of milk contain about 95 mg of caffeine.

What does this mean?

A Flat White serving containing 2 shots of espresso has more caffeine than a 16-ounce Cafe Au Lait.

When it comes to calories, a 6 Oz Cafe Au Lait contains 3 ounces of milk, while a 6 Oz Flat White has 4 ounces of milk and 2 shots of espresso.

So:

In terms of calories, a Flat White has more calories since it contains more milk and also has more caffeine.

Conclusion

Cafe Au Lait and Flat Whites are two completely different coffee beverages. Here is a recap of how they differ.

  • The Cafe Au Lait originated in France in the 1600s.
  • A Flat White came from Down Under in the mid-1980s.
  • A Cafe Au Lait contains half coffee and hot or steamed milk.
  • A Flat White is made with 1/3 espresso and 2/3 microfoam.
  • A Flat White is traditionally a small drink of around 6 Oz.
  • A Flat white has more caffeine and calories than Cafe Au Lai.
