The flat white is the espresso drink that changed how coffee shops think about milk drinks. Smaller than a latte, stronger than a cappuccino, and smoother than either — it sits in a sweet spot that converted a generation of café drinkers who thought they were latte people. If your latte feels watered down but a macchiato feels too extreme, the flat white is probably exactly what you’ve been looking for.
This guide explains exactly what a flat white is, where it came from, how it differs from lattes and cappuccinos, what “microfoam” actually means, and how to make one at home.
What is a flat white?
A flat white is a double espresso shot with a thin layer of velvety microfoamed milk, served in a 5–6 oz ceramic cup. The “flat” in the name refers to the foam: flat white foam is dense, silky, and barely raised above the rim — not the thick pillow of a cappuccino, not the minimal foam of a latte. It’s the Goldilocks of coffee foam.
The result is a small, strong milk coffee with an intense espresso flavor. The milk texture is the defining feature: tighter and silkier than a latte, which makes the espresso taste more present and integrated rather than diluted in milk.
Where did the flat white come from?
The flat white was independently developed in Australia and New Zealand in the 1980s — both countries claim invention and the dispute remains affectionately unresolved. What’s agreed is that it emerged from dissatisfaction with two existing options: the cappuccino’s excessive foam and the latte’s excessive milk. Australian and New Zealand café culture became globally influential partly through the flat white, which spread to the UK and US through the specialty coffee movement.
Starbucks added the flat white to their US menu in 2015, cementing it as mainstream. Their version uses ristretto shots (shorter, slightly sweeter extraction) with whole milk steamed to a specific microfoam texture — a reasonable interpretation of the original concept at scale.
Flat white vs latte: the real difference
The flat white and latte are the most commonly confused pair in coffee shops. Both use a double espresso and steamed milk. The difference is purely ratio and volume:
| Feature | Flat White | Latte |
|---|---|---|
| Volume | 5–6 oz | 10–12 oz |
| Espresso | Double (sometimes ristretto) | Double (standard) |
| Coffee ratio | ~33% espresso | ~18% espresso |
| Foam | Thin, dense microfoam | Thicker, more airy foam |
| Flavor | Stronger, coffee-forward | Milder, creamy |
| Caffeine | ~126 mg | ~126 mg |
The critical insight: same two espresso shots, but in half the volume. That makes the flat white taste roughly twice as coffee-forward, even though it contains identical caffeine. If your latte feels watery, a flat white solves it without changing how much coffee you’re actually drinking. See our latte guide for context on milk ratios.
Flat white vs cappuccino: a matter of foam
A cappuccino is traditionally equal thirds espresso, steamed milk, and foam — a drier, airier texture with a more substantial foam cap above the rim. The flat white has much less foam (it’s “flat,” meaning barely raised) and slightly more milk, making it silkier and less airy than a cappuccino despite being a similar size.
Choose a cappuccino for texture and foam drama. Choose a flat white for a silkier, stronger, more integrated espresso-milk experience. Our cappuccino guide covers the full comparison including ratios and how to make one.
Flat white vs cortado: the closest comparison
The cortado (Spanish) and flat white (Australian) are the closest cousins in espresso drinks — both prioritize espresso intensity with minimal milk. Key differences:
- Cortado: 1:1 espresso to milk. ~4 oz. Minimal foam. Served in a small glass.
- Flat white: 1:2 ratio with a defined microfoam layer. 5–6 oz. Latte art is possible. Served in ceramic.
The cortado is more concentrated; the flat white has a more defined foam texture that holds latte art. See our cortado guide for the side-by-side breakdown.
What is microfoam and why does it matter?
Microfoam is steamed milk where the bubbles are so small they’re invisible — the texture looks glossy and thick, almost like wet paint, rather than bubbly or frothy. Microfoam is what makes latte art possible, and it’s what gives a flat white its defining silky texture.
To create microfoam: keep the steam wand tip just at the surface of the milk while steaming, incorporating as little air as possible. The milk should spin in the pitcher rather than bubble up. Stop at 130–140°F — the milk should feel uncomfortably hot to the touch but not scalding. Swirl the pitcher to break any remaining bubbles before pouring.
Without a steam wand, a handheld milk frother held just below the milk surface for 15–20 seconds gets you close enough. The texture won’t be identical but the flat white ratio still works well with lightly frothed milk.
How to make a flat white at home
Equipment: Espresso machine with steam wand (a moka pot and handheld frother as a workaround), a 5–6 oz ceramic cup preheated with hot water.
- Preheat your cup — fill with hot water, wait 30 seconds, discard. The flat white’s small volume loses heat fast in a cold cup.
- Pull a double espresso — 18g of freshly ground coffee, targeting 36g yield. A ristretto (shorter pull, 30g yield) is sweeter and works especially well in a flat white.
- Steam 3–4 oz of whole milk to 130–140°F, creating microfoam. Keep the wand tip near the surface and don’t let the milk bubble up. The finished milk should look thick and glossy.
- Pour the milk into the espresso in one smooth, continuous motion from low to the cup. The microfoam should integrate into the espresso, leaving just a thin layer of foam on the surface.
- For latte art: tilt the cup, pour a thin stream into the center, then move the pour through the front to create a heart. Takes practice — the milk texture does most of the work.
Why whole milk makes the best flat white
Whole milk creates the most stable, silky microfoam because of its fat and protein structure. Skim milk foams lighter and drier — the foam collapses faster. Barista oat milk is the best alternative — it emulsifies similarly to whole milk and creates comparable microfoam texture. Almond milk tends to separate under steam. For a flat white specifically, where the foam texture is the whole point, milk choice matters more than in a latte. Our brewing guide has more on how milk type affects espresso drinks.

Frequently Asked Questions About Flat White
What is a flat white coffee?
A flat white is an espresso drink originating in Australia and New Zealand — a double espresso with 3–4 oz of thinly microfoamed milk in a 5–6 oz ceramic cup. Smaller and stronger than a latte, with less foam than a cappuccino. The foam is “flat” — dense and barely raised above the rim.
What is the difference between a flat white and a latte?
Same espresso, very different ratios. A flat white is 5–6 oz total (about 33% espresso). A latte is 10–12 oz total (about 18% espresso). The flat white tastes significantly stronger because there’s less milk. The foam on a flat white is also denser and thinner than a latte’s slightly airier top layer.
Is a flat white stronger than a cappuccino?
In caffeine: about the same — both typically use a double espresso. In flavor: the flat white often tastes more coffee-forward because its foam is thinner and less airy than a cappuccino’s, so the milk adds less perceived sweetness and dilution to the espresso.
What size is a flat white?
Traditional flat whites are 5–6 oz (150–180ml). Starbucks serves theirs in a 12 oz “tall” cup by default — significantly larger than traditional, which dilutes the espresso-to-milk ratio toward latte territory. If you want the proper flat white experience at Starbucks, ask for it in a short (8 oz) cup.
Can you make a flat white without an espresso machine?
The flat white really needs concentrated espresso for the right flavor balance. A moka pot is the closest substitute — brew 2 oz of strong moka coffee and add 3 oz of lightly frothed whole milk. The texture won’t be identical to proper microfoam, but the ratio and flavor direction will be similar. See our latte at home guide for moka pot technique.
Is a flat white sweet?
A flat white has no added sweetener. The sweetness you taste comes from a well-extracted espresso (a properly pulled shot should taste slightly sweet without sugar) and the natural lactose in the steamed milk. If you want sweetness, add simple syrup — but try it without first, since good espresso in a flat white often doesn’t need it.
