Flat White vs Cortado

Last updated: September 24, 2026

Walk into a specialty café and the flat white and the cortado sit a few lines apart on the menu, often at nearly the same price. Both are small, strong, milk-and-espresso drinks without a cappuccino’s foam cap, so people assume they are interchangeable. They are not. The cortado is a Spanish half-and-half cut; the flat white is an Australian and New Zealand drink built around velvety microfoam and a larger volume. If you make them at home, the difference changes how you steam, what cup you reach for and even which shot recipe you pull.

The Short Answer

A cortado is roughly equal parts espresso and warm, lightly textured milk, usually 120-135 ml (4-4.5 oz) in total. A flat white is a double shot topped with more milk, typically 150-180 ml (5-6 oz), steamed into a thin, glossy layer of microfoam and often finished with latte art. The cortado tastes more like coffee with the edges softened; the flat white tastes like a creamy, coffee-forward milk drink.

How the Espresso Changes the Drink

Cortado shots

Because the milk only matches the coffee, a cortado exposes the espresso. A sharp, underextracted shot shows up immediately as sourness, and a very dark roast can taste ashy. Many home baristas use a standard double of 18 g in to 36-40 g out, then pour the same weight of milk. Medium roasts with chocolate and caramel notes are the forgiving choice here.

Flat white shots

The traditional flat white leans on a double ristretto, something like 18 g in to 25-30 g out. A shorter, more concentrated shot punches through the extra milk so the drink stays coffee-led rather than tasting like a small latte. If your machine or grinder struggles to pull a clean ristretto, a normal double works, but consider keeping the cup at 150 ml rather than 180 ml.

Steaming Technique for Each

Texturing milk for a cortado

You want warmth and a little body, not foam. Keep the steam tip buried just under the surface from the start, stretch for only a second or two, and stop early. Stopping around 55-60 °C preserves the milk’s sweetness and keeps it pourable into a narrow glass without a white cap. On a small single-boiler machine, 80-100 ml of milk in a 350 ml (12 oz) pitcher is easier to control than a big jug.

Texturing milk for a flat white

This is where the drink is won or lost. Stretch briefly to add a small amount of air, then sink the wand to create a whirlpool that folds big bubbles into microfoam with a wet-paint sheen. Aim for a thinner foam layer than a latte; if you can see a stiff white island in the cup, you over-stretched. Pour from a little height first to sink the milk under the crema, then drop close to the surface to draw a heart or tulip.

Equipment That Suits Each Drink

Cortados are the easier drink on entry machines. Even a thermoblock machine with a panarello wand can produce warm, lightly aerated milk for a 4 oz pour. Flat whites need real microfoam, which favors a machine with a traditional steam wand and enough steam pressure to roll the milk: a heat-exchanger or dual boiler is ideal, while thermojet machines like the Breville Bambino Plus manage it well at small volumes. A 12 oz pitcher with a sharp spout matters more for the flat white, because a crisp pour is part of the drink.

Calories, Caffeine and Cost at Home

Both contain a double shot, so caffeine is similar, roughly 120-150 mg depending on beans and yield. The flat white uses 50-100% more milk, so with whole milk it lands around 90-120 kcal against 60-80 kcal for a cortado. At home the cost per drink is dominated by beans at roughly $0.60-1.20 per double, with milk adding only a few cents, so neither drink is meaningfully cheaper to make.

Which Should You Order or Make?

Pick the cortado when you want to taste a specific bean, when you are drinking in the afternoon and want something short, or when your machine’s steam wand is weak. Pick the flat white when you want a creamy morning drink that still tastes clearly of coffee, or when you are practicing latte art on a small canvas. If you enjoy a lighter, fruity roast, the flat white’s extra milk can mute acidity pleasantly, while the cortado will show it off.

FAQ

Is a flat white stronger than a cortado?

Not in caffeine, since both usually use a double shot. The cortado tastes stronger because there is less milk diluting the espresso; the flat white can taste punchy only when it is built on a ristretto.

Can I use oat milk for either drink?

Yes. Barista-style oat milks steam into decent microfoam for a flat white; for a cortado choose a creamier oat or soy blend, because thin plant milks at a 1:1 ratio can make the drink taste watery.

Bottom Line

The cortado is a short, balanced cut of espresso with warm milk; the flat white is a slightly larger, silkier drink that depends on excellent microfoam and a concentrated shot. At home, start with cortados if your steaming is still inconsistent, then graduate to flat whites once you can make glossy, thin foam on demand.
