To learn how to make a flat white, pull a double shot of espresso (or a strong stovetop or AeroPress substitute) and top it with steamed milk that carries only a thin, glossy layer of microfoam. The drink lands smaller and stronger than a latte, poured to about 150 to 180ml total, with a higher coffee-to-milk ratio and silky, barely-there foam. Get those two things right and everything else is just finishing.
What a flat white actually is
A flat white is an espresso-based milk drink built on a double shot and topped with steamed milk textured into fine microfoam rather than a thick, dry foam cap. The espresso stays close to the surface, so you taste the coffee first and the milk second. If you want the full definition and its cafe history, see what a flat white is; for a side-by-side breakdown of where it parts ways with its bigger cousin, read the flat white vs latte comparison. In short: the same two ingredients as a latte, but less milk, thinner foam and a stronger cup.
Compared with a cappuccino, which is built in roughly equal thirds of espresso, steamed milk and a deep layer of dry foam, a flat white keeps the foam thin and wet so the texture reads velvety rather than airy. The origin is worth a nod too: the flat white is generally credited to cafes in Australia and New Zealand in the 1980s, and it traveled around the world from there.
Ingredients and gear
- Coffee. A double shot of espresso, about 30 to 40ml, is the classic base. No machine? A strong moka pot or a concentrated AeroPress brew stands in well (more on that below).
- Milk. Cold, fresh milk straight from the fridge, roughly 120 to 150ml. Whole dairy milk steams into the silkiest microfoam thanks to its fat and protein, but a barista-formulated oat or soy milk textures nicely too.
- A way to texture milk. A steam wand is ideal, but a handheld electric frother, a small milk steamer, a French press, or even a sealed jar plus a microwave can all get you close.
- A cup. A 150 to 180ml tulip cup or small ceramic mug. It is smaller than a latte glass on purpose.
Choosing your milk
Because the milk is the second-loudest voice in a flat white, what you steam matters. Whole dairy milk is the easiest to texture and gives the sweetest, most stable microfoam. Semi-skimmed foams a little airier and lighter. Among plant milks, barista-formulated oat is the crowd favorite for flat whites because its added protein and fat build a glossy foam and its mild sweetness sits well under espresso; barista soy and some pea-based blends also steam well. Standard almond or rice milk tends to foam thin and can split against a hot shot, so reach for a barista blend if you can. Whatever you pour, start cold, straight from the fridge, since cold milk buys you more time to build texture before it overheats.
How to make a flat white, step by step
Here is how to make a flat white from the first grind to the final pour. Work quickly once the milk is textured, because microfoam sets fast.
- Warm the cup. Rinse it with hot water so the drink holds its temperature while you pour.
- Pull the double shot. Grind fresh, dose about 18g, and pull roughly 30 to 40ml of espresso into your warmed cup. Aim for a shot that runs like warm honey with a hazelnut-colored crema on top.
- Steam the milk to microfoam. Pour cold milk into a jug, introduce just a whisper of air for a second or two, then submerge the wand tip to spin the milk into a glossy whirlpool. You want tiny, paint-like bubbles, not stiff peaks. This texturing step is the make-or-break move; the full technique lives in how to make steamed milk.
- Tap and swirl. Knock the jug on the counter to pop any large bubbles, then swirl until the milk looks like wet paint with a shine.
- Pour close to the surface. Start pouring from a little height to let the espresso and milk mix, then drop the jug spout close to the surface near the end to float a thin foam layer and, if you like, wobble in a little latte art.
The finish should be a barely-there foam cap, maybe half a centimeter, sitting flat and glossy on top. That flat, white surface is exactly where the name comes from.
Ratio and cup size: why it is stronger than a latte
The flat white is a smaller, more concentrated drink than a latte, and the ratio is the reason. A flat white runs roughly one part espresso to three or four parts milk in a 150 to 180ml cup. A latte uses a similar shot but stretches it under far more milk in a 240 to 350ml glass, so the coffee is diluted and the foam is taller. Same espresso, less milk, and you land a bolder, sweeter cup. If you want the milkier version instead, our guide to how to make a latte at home walks through the taller pour.
| Element | Flat white | Latte |
|---|---|---|
| Espresso | Double shot (30-40ml) | Single or double shot |
| Total size | 150-180ml | 240-350ml |
| Coffee-to-milk ratio | About 1:3 to 1:4 | About 1:4 to 1:6 |
| Foam | Thin microfoam, about 0.5cm | Thicker foam cap, 1cm or more |
| Strength | Bolder, coffee-forward | Milkier, milder |
No machine? Make a flat white without a steam wand
You do not need a cafe setup for a homemade flat white. For the coffee, brew a small, strong batch in a moka pot or a concentrated AeroPress shot, using less water than usual so the base stays intense. For the milk, heat it gently on the stove or in the microwave to about 60 to 65C, then froth it: a handheld electric frother, a French press pumped up and down, or a lidded jar shaken hard then microwaved for a few seconds all produce a workable microfoam. Tap and swirl exactly as you would with wand-steamed milk, then pour with only a thin foam layer. It will not be latte-art perfect, but the flavor and texture land close.
Common fixes
- Too foamy. You added air for too long. Cut the stretch to a second or two and spend the rest of the time swirling to break the big bubbles down.
- Milk too hot or thin. Milk scalded past about 70C tastes flat and loses its sweetness. Stop steaming when the jug is just too hot to hold for a couple of seconds, around 60 to 65C.
- Weak shot. A watery base gets lost under the milk. Grind finer, dose a touch more, and keep it to a proper double so the coffee reads through.
- Foam and milk separate. You waited too long to pour. Swirl and pour within a few seconds of texturing, while the microfoam is still folded in.
Dial in the shot, keep the foam thin and glossy, and pour it small. That is really all there is to a great flat white made at home.
