Cortado vs Flat White: Size, Ratio and Taste Compared (2026)

The cortado and the flat white are two of the most misunderstood drinks on the espresso menu. They are both small. They both use espresso and steamed milk. They both have minimal foam. And they are both ordered by people who want something stronger than a latte but smoother than a straight espresso.

So what actually separates them? The answer comes down to origin, ratio, milk texture, and the philosophy behind each drink. They are similar enough that many cafes treat them as interchangeable, but they are distinct enough that understanding the difference changes how you order and how you brew.

This guide breaks down every dimension of the cortado vs flat white comparison so you know exactly what you are getting when you order either one.

What Is a Cortado

Origin and Definition

The cortado is a Spanish espresso drink whose name comes from the Spanish verb cortar, meaning to cut. The milk cuts the intensity of the espresso, reducing its acidity and bitterness without diluting it the way a larger milk drink would. It originated in Spain and is a staple of cafe culture across the Iberian Peninsula and Latin America.

A cortado is made with a single or double espresso shot and an equal volume of warm, lightly steamed milk. The ratio is 1:1, meaning equal parts espresso and milk. A standard cortado is served in a small glass of around 60 to 90ml total volume. The milk is steamed to a warm temperature but with very little foam, just enough to soften the espresso without adding significant texture or volume.

What Makes a Cortado Distinctive

The cortado is defined by its strict 1:1 ratio. This is not a guideline. It is the structural principle of the drink. The equal parts espresso and milk produce a drink that is simultaneously intense and smooth, with the espresso character fully present but its harshest edges softened by the warm milk. The small volume means you drink it quickly, in two or three sips, rather than nursing it over 10 to 15 minutes the way you might a flat white or latte.

The milk in a cortado is steamed to a warm temperature with minimal foam. It is not the fine, glossy microfoam of a flat white. It is simply warm milk with a light surface texture, enough to integrate with the espresso but not enough to add significant body or creaminess to the drink.

What Is a Flat White

Origin and Definition

The flat white is an Australian and New Zealand invention that emerged in the early 1980s as a smaller, stronger alternative to the latte. It is made with a double ristretto or double espresso shot and a larger volume of steamed milk than a cortado, typically 100 to 130ml, giving a milk-to-espresso ratio of approximately 3:1 to 4:1. It is served in a 150 to 180ml ceramic cup.

The defining characteristic of a flat white is the milk texture. The microfoam must be extremely fine, glossy, and fully integrated into the milk, producing a smooth, flat surface with no visible bubbles. This is a higher technical standard than the cortado, which uses simply warmed milk rather than precisely textured microfoam. For the full story of the flat white's origins and global spread, our guide to what is a flat white covers everything in detail.

Key Differences: Ratio, Size and Milk Texture

Ratio

The cortado uses a 1:1 ratio of espresso to milk. The flat white uses a 3:1 to 4:1 ratio of milk to espresso. This is the most fundamental difference between the two drinks. The cortado has significantly more espresso relative to milk, making it more intense and less creamy. The flat white has more milk relative to espresso, making it smoother and more substantial while still being noticeably stronger than a latte.

Size

A cortado is typically 60 to 90ml total. A flat white is 150 to 180ml. The cortado is a two to three sip drink. The flat white is a drink you sit with for 10 to 15 minutes. This size difference reflects the different drinking cultures they come from: the Spanish tradition of a quick, intense coffee at the bar versus the Australian tradition of a considered, sit-down coffee experience.

Milk Texture

The cortado uses warm milk with minimal foam. The flat white uses precisely textured microfoam that is integrated throughout the milk. The flat white's microfoam standard is significantly more demanding technically and produces a noticeably different mouthfeel: smoother, creamier, and more velvety than the simply warmed milk of a cortado.

Taste Comparison

How a Cortado Tastes

A cortado tastes intensely of espresso with a warm, softening presence of milk. The 1:1 ratio means the coffee character is dominant and the milk plays a supporting role. The drink is bold, direct, and short. There is no creaminess in the way a flat white or latte has creaminess. The milk simply takes the edge off the espresso's acidity and bitterness without adding significant body or sweetness.

If you enjoy the flavour of espresso but find it too harsh or acidic to drink straight, a cortado is the minimal intervention that makes it more approachable without fundamentally changing its character.

How a Flat White Tastes

A flat white tastes bold and coffee-forward, but with a noticeable creaminess and smoothness that the cortado lacks. The larger milk volume and the fine microfoam add body and sweetness to the drink, rounding off the espresso's edges more fully than the cortado's warm milk does. The flat white is more satisfying as a standalone drink and more suitable for slow, considered drinking.

If you want the intensity of espresso with the comfort of a milk drink, the flat white delivers that balance more completely than the cortado. If you want the espresso to be the undisputed star with milk playing the smallest possible supporting role, the cortado is the better choice.

Which One Should You Choose

Choose a Cortado If...

You love the flavour of espresso and want the smallest possible amount of milk to soften it. You prefer a quick, intense coffee experience rather than a drink you sit with. You find flat whites and lattes too milky but straight espresso too harsh. The cortado is the most espresso-forward milk drink on the menu and is ideal for people who want their coffee to taste like coffee first and milk second.

Choose a Flat White If...

You want a strong, coffee-forward drink with a smooth, velvety texture and enough milk to make it a satisfying, sit-down experience. The flat white is ideal for people who appreciate espresso intensity but want the comfort and creaminess of a milk drink. It is also the better choice if you enjoy latte art, as the fine microfoam is the canvas that makes it possible.

The Honest Answer

Both drinks are excellent and serve different purposes. The cortado is a quick, intense hit of espresso with minimal milk. The flat white is a considered, satisfying coffee experience that balances strength and smoothness. Try both and see which one fits your drinking style.

How to Make Each One at Home

Making a Cortado at Home

Pull a double espresso shot into a small glass of around 90ml capacity. Steam approximately 30 to 40ml of full-cream milk to around 55 to 60 degrees Celsius with minimal air introduction. The milk should be warm and smooth with very little foam. Pour the warm milk directly over the espresso. The finished drink should be around 60 to 80ml total and taste intensely of espresso with a warm, softening presence of milk.

Making a Flat White at Home

Pull a double ristretto into a prewarmed 150 to 180ml ceramic cup. Steam 120 to 130ml of full-cream milk to 60 to 65 degrees Celsius, introducing a very small amount of air in the first two to three seconds and then focusing on creating a fast circular whirlpool to develop fine, glossy microfoam. Pour the milk over the espresso in a slow, controlled stream. The finished drink should have a smooth, flat surface of integrated microfoam.

FAQ About Cortado vs Flat White

Is a cortado stronger than a flat white

Yes, in terms of espresso intensity. The cortado's 1:1 ratio means the espresso is less diluted by milk than in a flat white, producing a more intense, espresso-dominant flavour. The caffeine content is similar when both are made with a double shot, but the cortado tastes significantly stronger because there is less milk to soften the espresso character.

Is a cortado the same as a flat white

No. They are similar in that both are small, strong espresso drinks with steamed milk and minimal foam, but they differ in ratio, size, milk texture, and origin. The cortado uses a 1:1 ratio and is 60 to 90ml total. The flat white uses a 3:1 to 4:1 milk-to-espresso ratio and is 150 to 180ml. The flat white also uses a more precisely textured microfoam than the simply warmed milk of a cortado.

What is a cortado called in Australia

In Australia, a cortado is usually called a cortado, though some cafes may list it as a piccolo latte, which is a similar drink made with a single ristretto and around 90ml of steamed milk. The piccolo latte is the Australian equivalent of the cortado and is more commonly found on Australian menus than the cortado itself.

Which has more milk: cortado or flat white

The flat white has significantly more milk. A cortado uses equal parts espresso and milk, typically 30 to 40ml of milk for a double shot. A flat white uses 100 to 130ml of steamed milk for the same espresso base. The flat white is a noticeably milkier, creamier, and more substantial drink.
