Flat white

What is in the cup

Typical range

Why the foam is thin, and why that matters

CoffeeHQ explanation

Steaming milk does two jobs at once: it heats the milk and it folds air into it. How much air goes in during the first few seconds decides the result. A cappuccino takes a lot of air and ends up with a deep, spoonable foam; a flat white takes very little, so the bubbles stay too small to see and the milk thickens only slightly.

That thin texture is the point. Because the foam is integrated with the milk instead of floating on it, every sip is the same blend of coffee and milk from first to last, and the surface is the smooth, slightly glossy finish the drink is named for. A flat white with a thick dry cap is a small cappuccino.

Making one at home

CoffeeHQ explanation

You need an espresso machine with a steam wand, a small milk jug and a cup of about 150–180 ml. Use a jug sized for one drink: steaming a small amount of milk in a large jug is much harder to control.

1. Pull a double shot into the cup. Brew the espresso first and steam straight away. Espresso left to stand loses its crema and its aroma within a couple of minutes.
2. Add only a little air. With the wand tip just under the surface, let in air for no more than two or three seconds. You should hear a few short, quiet hisses, not a sustained tearing sound.
3. Roll the milk until the jug is hot. Lower the tip slightly so the milk spins in a whirlpool with no more air entering. Stop when the jug is too hot to keep your palm on, which is before the milk begins to smell cooked.
4. Swirl, then pour without delay. Knock out any visible bubbles and swirl until the surface looks like wet paint. Pour steadily from low over the cup so the milk and coffee fold together.

In a café the only real difference is repetition: a barista steams the same quantity dozens of times a day, in a jug chosen so that the quantity needed fills it to the right depth.

If yours does not taste like the café's

Tendency, not a guarantee

It tastes like a small, weak latte

Usually because: Too much milk for the amount of coffee. A flat white made in a 250 ml mug, or with a single shot, has a latte's proportions whatever it is called.

Change first: Use a smaller cup before changing anything else. Keeping the double shot and cutting the milk is what restores the balance.

Work out the milk for your cup

A stiff, dry cap sits on top of thin milk

Usually because: Too much air went in, or the milk stood for too long after steaming and separated into foam and liquid.

Change first: Halve the time you spend letting air in, and pour within a few seconds of finishing.

Fix stiff, dry foam

The milk is hot but has no body or gloss

Usually because: Too little air, or the wand was buried too deep to draw any in. The milk has been heated without being textured.

Change first: Start with the tip closer to the surface so you hear air entering for the first two seconds.

Fix thin, flat milk

The coffee tastes bitter or sharp through the milk

Usually because: The fault is in the espresso. With this little milk there is nowhere for a harsh or sour shot to hide.

Change first: Taste the espresso on its own and correct that first, before adjusting anything about the milk.

Dial in the espresso

Making it stronger or milder

CoffeeHQ explanation

To make a flat white taste stronger, reduce the milk rather than adding coffee: a smaller cup with the same double shot raises the proportion of coffee without changing how the espresso extracts. Some cafés go further and pull the shot shorter, which makes it thicker and more intense for the same dose.

To make it milder, add milk and accept that you are moving towards a latte, or ask for a single shot in the same cup. Lengthening the shot to fill the cup is the one route to avoid, because it adds bitterness along with volume.

How it differs from the drinks next to it

Tendency, not a guarantee

• Latte — Usually the same or less coffee in a much larger cup, so it is milder and milkier, with a slightly deeper layer of foam.
• Cappuccino — A similar size, but with a deep cap of airy foam. The texture changes from foam to liquid as you drink it; a flat white stays the same throughout.
• Cortado — Smaller again and closer to equal parts coffee and milk, with almost no foam and usually no latte art.
• Piccolo — A single short shot with textured milk in a small glass: the flat white's texture at roughly half the size.

Where it came from

Accounts differ

The flat white emerged in Australia and New Zealand in the 1980s, and both countries claim it. Competing accounts credit cafés in Sydney and in Wellington, and there is no agreed first instance; the name itself plainly describes a white coffee without the raised foam of a cappuccino.

It spread through London and then international chains during the 2000s and 2010s. That history is part of why the recipe is so loosely held: the drink was a café habit long before anyone tried to write it down.

What to do next

• Making microfoam — the texture is the half of this drink that most home attempts miss, and it is a learnable skill.
• Latte vs. flat white — a side-by-side of the two drinks most often confused with each other.
• Pouring latte art — milk that is textured correctly for a flat white is also milk that will hold a pattern.
• Oat milk — if you are not using dairy, how a plant milk behaves under steam decides whether microfoam is possible at all.
• Become a barista — A structured programme from dose and grind through milk, drinks and maintenance.
