Flat White: Recipe, Differences, and Origin
The Flat White is the milk drink for anyone who really just wants coffee. Double espresso, little milk, barely any foam – and an origin story that three countries are still fighting over. Here's what's documented and what's just claimed.
Up front: if you'd rather drink a cappuccino, you're not missing out. The Flat White isn't an upgrade – it's just a different distribution of the same ingredients.
What Is a Flat White?
A Flat White is a double espresso with frothed milk, topped with only a paper-thin layer of microfoam. One widely used recipe calls for 50 milliliters of espresso, about 130 milliliters of milk, and a foam layer of roughly five millimeters – around 175 milliliters together.
The name describes exactly that: flat for the flat surface with no mountain of foam, white for the milk. Not a marketing term, but a description.
Unlike the cappuccino, there's no institutional definition for the Flat White. The figures above come from a widely used professional recipe, not a standard. Order one each in Auckland, Sydney, and London, and you'll get three different drinks.
Our Flat White
- About 30 grams of espresso in the cup – a double shot per our Espresso Dial-In.
- 120 milliliters of milk, frothed with as little air as possible.
- About 150 milliliters together – at the lower end of the usual range.
That works out to a ratio of 1:4 – exactly the same as the Italian cappuccino's 25 to 100 milliliters. So for us, the difference between the two drinks isn't in the amount of coffee, but purely in the foam and the shape of the cup.
That's more milk-forward than the professional recipe of 50 to 130 milliliters, which comes to roughly 1:2.6. Both are valid – we deliberately build our Flat White closer to the cappuccino, because we value the dense, glossy texture more than maximum coffee intensity. If you want it stronger, pull the same shot into 90 milliliters of milk instead of 120.
What's the Difference Between Flat White and Cappuccino?
Two things: foam thickness and the amount of coffee. The cappuccino carries a distinct foam cap and classically works with a single espresso; the Flat White has almost no foam and usually a double shot.
Where the difference lies
Layer thicknesses drawn to scale relative to the stated amounts; the split between liquid and foam for the cappuccino is an assumption.
That shifts the taste noticeably. In a cappuccino, air is an ingredient in its own right – it makes the cup lighter and milder. In a Flat White, that air is missing. The cup feels denser, shorter, and more intense, even when the amount of coffee is the same.
That's exactly what the third cup in the chart shows: our house version has the same coffee-to-milk ratio as the Italian cappuccino. It still tastes completely different – because without a foam cap, nothing stands between you and the milk.
What's the Difference Between Flat White and Caffè Latte?
The Flat White contains less milk and less microfoam than a Caffè Latte. The latte has a creamy, velvety layer; the Flat White a thinner layer of textured milk, ideally with a glossy surface.
| Flat White | Cappuccino | Caffè Latte | |
|---|---|---|---|
| Coffee | usually double | classically single | single or double |
| Milk | little | medium | a lot |
| Foam | approx. 5 mm, glossy | thick cap | creamy layer |
| Size | approx. 150–200 ml | approx. 125–180 ml | approx. 250–350 ml |
| Character | dense, coffee-forward | airy, balanced | mild, milk-forward |
Only the cappuccino figures trace back to an institutional specification. The other numbers describe common practice in the specialty coffee scene and vary considerably from café to café.
Where Does the Flat White Come From?
That's not conclusively settled – and that's the most honest answer there is. Three countries have documented claims, and none of them is proof.
Three countries, three pieces of evidence
Documented mentions, not proof of invention. The point at the 1950s is a hypothesis from coffee historian Ian Bersten, not a discovered artifact.
England has the oldest evidence for the term. In a British film from 1963, a character orders a flat white in an espresso bar, and in 1971 the expression appears in a published English source. Coffee historian Ian Bersten suspects an origin in England in the 1950s – a hypothesis, not a discovery.
Australia has the oldest evidence for the drink on a menu. In May 1983, a Sydney café is mentioned with "flat white coffee," and in April 1984 a Sydney newspaper equates "cafe latte" with "flat white." In 1985, Alan Preston puts the Flat White permanently on the menu of his Moors Espresso Bar and says he brought the idea from his home in North Queensland. In January 1985, during a milk shortage, a sign reading "flat white only" hangs in Parliament House in Canberra.
New Zealand pushes back. Derek Townsend and Darrell Ahlers of Auckland's Cafe DKD claim the invention as an alternative to the Italian latte – they say they heard the name from a staff member from Sydney. In Wellington, Craig Miller made the Flat White in the mid-1980s using an Australian recipe, and Bar Bodega on Willis Street is credited in 1989 with a botched cappuccino that supposedly gave rise to the Flat White.
What we like about this is that the story doesn't resolve. A drink that could plausibly have been invented in three places at once was, apparently, simply missing.
Why Does a Flat White Often Use a Ristretto?
Because the coffee has to hold its own against the milk. A double ristretto is more concentrated and less bitter than a regular double shot – exactly what a small amount of milk needs so it doesn't get covered up entirely.
It's not mandatory, though. A regular double espresso works just as well, especially with beans that already bring plenty of body. For how to nail both, see Espresso Dial-In – it also explains why we set the grind size once and then control everything through the dose.
What Is Microfoam – and Why Does It Shine?
Microfoam is milk foam with very fine, even bubbles. It doesn't sit on top as a lid, but is part of the milk: pourable, dense, and with a surface that reflects light evenly. That's exactly where the shine comes from.
Why the surface shines
Schematic illustration of the bubble structure – not a microscope image.
Coarse foam does the opposite. The large bubbles pop quickly, the foam separates from the milk, and the surface turns matte and stiff. That can still work for a cappuccino – in a Flat White, it shows immediately, because the thin layer hides no mistakes.
If you want to explore how air, temperature, and steam power interact without using up milk: our milk foam simulator shows it as a model.
How Do You Make a Flat White?
Flat White – Step by Step
- Choose your cup. 150 to 200 milliliters, wider rather than tall. We work at the lower end of that range. In too large a cup, the coffee gets lost.
- Pull a double shot. For us, that's about 30 grams of espresso in the cup – at a ratio of 1:2, that's roughly 15 grams of dose. Straight into the pre-warmed cup.
- 120 milliliters of milk, little air. Just one to two seconds at the surface – noticeably less than for a cappuccino. Then immediately go deeper and roll it.
- Up to 55 to 60 degrees. When the pitcher gets too hot for your hand, stop. Then swirl until the milk shines like wet paint.
- Start low, pour briskly. First pour the milk under the crema from a bit of height, then get close to the surface and lay down the final layer.
The critical point is step three. Almost every failed Flat White has too much air in it – and you can't take air back out afterward. A barista scale helps with the shot; with the foam, only practice helps.
What's fixed for us is the drink volume: about 30 grams of espresso to 120 milliliters of milk. The resulting dose of roughly 15 grams follows from our 1:1.5 to 1:2 ratio – it's calculated, not measured. For how we set the grind size to match, see Espresso Dial-In.
How Much Caffeine Does a Flat White Have?
Around 130 milligrams, if a double espresso forms the base. That puts it at roughly double a classic Italian cappuccino made with a single shot. The milk doesn't change that – it contains no caffeine and just makes the drink bigger.
With our house version, using about 15 grams of dose, the figure lands in the same range. If you want less caffeine, switch to a single shot and keep the same amount of milk – that gives you a milder, but still dense, Flat White.
This is where a lot of people get it wrong: a Flat White tastes milder than an espresso, but carries more caffeine than a single cup of espresso.
Which Milk Suits a Flat White?
Whichever one produces fine foam – and for a Flat White, that matters more than for any other milk drink, because the thin layer hides nothing. Cow's milk makes it easiest; barista versions of plant-based drinks come close.
The numbers behind this – protein content, foam stability, and why plant-based drinks curdle in coffee – are covered in detail in the cappuccino article. In short: protein holds the foam, coffee lowers the pH, and barista formulations compensate for both.
In a Flat White, the inherent flavor of a milk alternative stands out more than in a cappuccino, because there's less air and less volume standing in between. Which combination works with which roast is best found out by trying it yourself – we've got suitable coffee beans.
Frequently Asked Questions About Flat White
What is a Flat White?
A Flat White is a double espresso with frothed milk, topped with only a paper-thin layer of microfoam. A widely used recipe calls for 50 milliliters of espresso, about 130 milliliters of milk, and a foam layer of roughly five millimeters. There is no binding standard.
What's the difference between Flat White and cappuccino?
The cappuccino has a thick foam cap, the Flat White almost none. Common recipes also give the Flat White more espresso. But the foam is what really matters: even at the same coffee-to-milk ratio, the Flat White tastes denser, because the air is missing.
What's the difference between Flat White and latte?
A Flat White contains less milk and less microfoam than a Caffè Latte. The latte has a creamy, velvety layer; the Flat White a thinner layer of textured milk with a glossier surface – and, as a result, more coffee flavor per sip.
Where does the Flat White come from?
That's not conclusively settled. England has the oldest evidence for the term – a film from 1963 and a dictionary entry from 1971. Australia and New Zealand have the oldest evidence for the drink appearing on a menu, from 1983 in Sydney and the mid-1980s in Auckland and Wellington.
How much caffeine does a Flat White have?
Around 130 milligrams, if a double espresso forms the base – roughly double a classic Italian cappuccino made with a single shot. The milk doesn't change that; it contains no caffeine.
How big is a Flat White?
Usually between 150 and 200 milliliters. One widely used recipe names 175 milliliters as the ideal size. We work with about 150 milliliters – 30 grams of espresso to 120 milliliters of milk.
How do you make the Flat White at the Coffee Coaching Club?
With about 30 grams of espresso in the cup and 120 milliliters of milk, roughly 150 milliliters together. That works out to a 1:4 ratio – the same as the Italian cappuccino. For us, the difference lies entirely in the foam: as little air as possible, in favor of a dense, glossy texture.
Is a Flat White made with ristretto?
Often, but not necessarily. A double ristretto makes the cup denser and sweeter, and helps the coffee hold its own against the milk. A regular double espresso works just as well – it's a question of the bean and of taste.
Why does the surface of a Flat White shine?
Because the foam is made of very fine bubbles. Microfoam blends with the milk instead of sitting on top, stays pourable, and reflects light evenly. Coarse foam, by contrast, looks matte and separates within seconds.
Now What?
The Flat White is a good test of your own milk technique. It forgives nothing, but it doesn't demand wizardry either – just less air than you're used to, and an espresso that can hold up.
You'll find the right espresso machines and barista tools in the shop. And if you'd rather go through it once at the machine than read about it: join a workshop in Bern or Zurich. We're United by Coffee – foam cap or not.
