What is the difference between a cortado and a flat white?

Quick answer

The main difference between a cortado and a flat white is the ratio of espresso to milk and the texture of the milk. A cortado is a 1:1 ratio of espresso to steamed milk with little to no foam. A flat white features a higher ratio of milk to espresso and is topped with a thin layer of microfoam.

The real story

Navigating espresso-based drinks is a core part of coffee basics, and the distinction between a cortado and a flat white often comes down to the balance of strength and texture. Both drinks are designed to highlight the espresso, but they achieve this through different approaches to milk preparation and volume.

A cortado, which takes its name from the Spanish word 'cortar' (to cut), is intended to 'cut' the intensity of the espresso with an equal amount of warm milk. It is typically served in a small glass, usually around 4 to 5 ounces total. The milk is steamed to a silky, liquid consistency without creating significant foam. The result is a drink that is bold, punchy, and retains the distinct flavor profile of the espresso shot, making it a favorite for those who want a bit of creaminess without masking the coffee.

A flat white, which originated in the scenes of Australia and New Zealand, is a larger drink, typically ranging from 5 to 6 ounces. It uses a double shot of espresso topped with steamed milk that has been textured into 'microfoam'—tiny, uniform bubbles that give the milk a velvety, paint-like consistency. The 'flat' in the name refers to the thin, smooth layer of foam on top, which is distinct from the thick, airy 'cap' of foam found on a traditional cappuccino.

In practice, the choice between the two depends on what you are looking for in your morning cup. If you want a quick, intense hit of coffee with just enough milk to take the edge off the bitterness, the cortado is your best bet. If you prefer a longer, more indulgent drink with a creamy, luxurious mouthfeel that integrates the espresso and milk into a single, harmonious flavor, the flat white is the superior choice. Both rely on high-quality espresso, so the quality of your beans and the precision of your extraction will ultimately dictate the success of either drink.
