What's the Difference Between Latte and Flat White? What's the Coffee-to-Milk Ratio in Latte? What are the Characteristics of Flat White?

Latte vs. Flat White: The Key Differences

"Latte" is the most popular Italian milk coffee, while "Flat White" is the rising star of the milk-coffee world. Both are milk coffees, but because they are built differently, they end up tasting and feeling quite unlike each other. To a beginner, asking about the difference can feel like asking how Ultraman Tiga differs from Ultraman Taro. So today, FrontStreet Coffee will walk through what really sets these two much-loved drinks apart.

Only joking. Today, FrontStreet Coffee will share the real differences between Latte and Flat White - in both preparation and flavor.

What Are Latte and Flat White?

Latte comes from the Italian "latte," and refers to a milk coffee made with a generous amount of milk and espresso. Its distinctive latte art and crowd-pleasing taste have made it enormously popular.

Flat White is a specialty milk coffee that developed in Australia. Because its flavor and texture differ from traditional Italian milk coffees, it spread widely after being popularized by the big coffee chains. Most specialty coffee shops now serve one, which is why it truly deserves its "rising star" label.

FrontStreet Coffee believes the differences come down mainly to three things: the espresso base, the cup size, and the thickness of the milk foam. Let's start with the espresso base. "For those curious about the history of these two milk coffees, see our two articles 'Latte Portal' and 'Flat White Portal.' FrontStreet Coffee won't go into that here."

1. Espresso Base

As everyone knows, the espresso base used in a Flat White differs somewhat from that of a standard Italian milk coffee. The espresso in a Latte, for instance, is a fully extracted shot with a balanced blend of sweet, sour, and bitter flavors, with no single taste pushed to the fore.

The espresso base in a Flat White has a name of its own: Ristretto. A Ristretto extracts only the front and middle portions of the shot, cutting back on the bitter compounds so the coffee reads sweeter. That is why a Flat White usually tastes more strongly of coffee than a Latte yet is not particularly bitter.

It helps to know, though, that a Ristretto works much like iced pour-over coffee - less liquid is used to draw out more compounds. Getting there means adjusting the grind size or the dose, which for a busy café is an extra hassle. In practice, most cafés simply use a regular espresso to make their Flat Whites.

2. Cup Size

The second difference is how much milk goes in. Because a Latte uses so much milk, Italians named it "caffè latte" outright. A Latte generally uses five times as much milk as espresso, a 1:5 ratio, though this should be adjusted to suit the beans. With that much milk, the lactose makes the drink easier on the palate, so even people who dislike bitterness can enjoy it - which is why it is praised as a milk coffee for all ages.

A Flat White, by contrast, uses relatively less milk, because the goal is to highlight the coffee's sweetness. The milk is held back so it does not simply cancel out the coffee. A Flat White generally uses 3.5 to 4 times as much milk as espresso. At that ratio, the coffee's own flavor survives and the drink still has a fuller, richer texture.

3. Milk Foam Thickness

The final difference is the thickness of the milk foam. Foam gives the coffee a creamy texture and makes latte art possible, so for many milk coffees a fine, delicate foam is essential.

When the Flat White was first created, though, baristas did not want a thick layer of foam weighing down the texture. Its foam is therefore very thin - less than 0.5mm. It gives up the creamy thickness that a "thick" foam brings, but in exchange you taste the milk coffee far more directly. One sip and you are straight into the coffee.

To sum up: if you want a creamy texture and more sweetness, choose a Latte, with its greater volume of milk and slightly thicker foam. If you would rather experience the coffee flavor directly, a Flat White - light, thinly foamed, and less bitter - is the right call.

One Small Extra Difference

There is one more small distinction worth mentioning: the options each drink offers. A Latte can be made hot or iced, but a Flat White cannot. Although the Flat White, like the Latte, was hot from the start, even today it is served only hot. Since there is no iced version, "Iced Flat White" remains a phrase that makes baristas break into a cold sweat. Why? Those who know, know.

FrontStreet Coffee Recommendation

If you want to practice your own latte art at home, FrontStreet Coffee's Classic Blend is a great place to start. This medium-dark espresso recipe is built from three origins, inspired by the old-school "Mamba" combination of Mandheling and Brazil, with a small amount of Robusta added for aroma and body. It releases clear notes of butter, toasted bread, and caramel cookie during extraction, with a strong flavor, a solid mouthfeel, and fine, delicate crema that extracts very consistently - a must-have home coffee for beginners.

If you prefer a nutty, full-bodied style, try FrontStreet Coffee's Specialty Blend. Also a medium-dark espresso, it pairs washed Colombian beans with semi-washed Brazilian beans for classic nut, dark chocolate, and caramel notes. Whether you make an Americano or a milky drink like a latte or flat white, it brings forward creamy, almond, and cocoa aromas, with crema every bit the equal of a café's - more than enough for practicing latte art.

And if you are aiming to open a shop, FrontStreet Coffee's Commercial Blend was made for you. It is a traditional Italian-style recipe built on the Specialty Blend with a little Robusta added, which contributes more fine, deep-brown crema and a heavier body. Americano, latte, or mocha, it carries nut, cocoa, and caramel flavors throughout - and makes latte art effortless.
