How to Make a Flat White

A flat white is one of the more satisfying drinks to get right at home. Small, strong, and draped in silky microfoam, it rewards a bit of technique in a way that larger milk drinks tend to hide. Once you nail the ratio and the steam, you will find yourself reaching for it most mornings instead of a latte.

This guide covers what a flat white actually is, how it differs from a latte, what you need to make one, and a step-by-step flat white recipe you can follow at home today.

What Is a Flat White?

A flat white is a small espresso-based drink, typically 5 to 5.5 oz (150 to 160 ml) total, made with a double ristretto or double espresso and a thin layer of steamed milk with very little foam. The name refers to the surface: flat, with just a thin coat of microfoam rather than the thick cap you get on a cappuccino.

The drink originated in Australia and New Zealand sometime in the 1980s, though both countries still argue the details. What both agree on is the character: concentrated espresso flavor with enough milk to round off the bitterness, served in a small ceramic cup.

Because the drink is small, the coffee-to-milk ratio sits around 1:3 to 1:4 by volume. That makes it noticeably stronger than a latte, which typically runs 1:6 or more. You taste the espresso first; the milk is there to support it, not to dilute it.

Flat White vs. Latte: The Real Differences

The flat white and the latte share the same ingredients, so the difference comes down to ratio and texture.

Size and ratio

A standard latte runs 8 to 12 oz (240 to 360 ml), built on a single or double espresso. The result is a milk-forward drink where the coffee flavor is present but gentle. A flat white comes in at roughly 5.5 oz, using a double ristretto (or double espresso) as the base. That smaller cup means less milk diluting the shot, so the espresso character stays front and center.

Milk texture

Both drinks use steamed milk, but the target texture differs. A latte has a bit more foam on top, usually half an inch or so. A flat white calls for thinner, silkier microfoam stretched to a very fine texture with almost no visible bubbles. The milk pours in a thin ribbon rather than spooned on. That texture is what gives the flat white its characteristic mouthfeel, smooth and coating without being heavy.

Cup size

Serving a flat white in an 8 oz cup defeats the purpose. You want a 5 to 6 oz ceramic cup or glass so the proportions stay correct. Cafes sometimes serve them in a 6 oz tulip cup; at home, a small ceramic mug works fine as long as it is not oversized.

What You Need for a Flat White at Home

You do not need commercial gear, but a home espresso machine with a steam wand is required. A French press or pour-over cannot replicate the pressure extraction and the steamed milk texture that define the drink.

For the espresso:

• Freshly ground coffee: 16 to 18 g (double basket)
• Grind: fine, similar to table salt or slightly finer
• Target yield for a double ristretto: 24 to 28 ml out, in 20 to 25 seconds
• Target yield for a standard double espresso: 32 to 36 ml out, in 25 to 30 seconds

For the milk:

• Whole milk, cold from the refrigerator: approximately 100 to 110 ml (3.5 to 4 oz)
• Cold milk steams better, giving you more time to build texture before reaching target temperature
• Non-dairy alternatives work, but oat milk tends to texture the most reliably; nut milks can produce thinner, less stable foam

Equipment:

• Home espresso machine with a steam wand
• 20 ml shot glasses or a small pitcher for measuring
• Steaming pitcher, ideally 12 oz (350 ml), which gives enough room to swirl without spillover
• A thermometer (optional, but helpful until you can read temperature by touch)
• 5 to 6 oz ceramic cup, preheated

How to Make a Flat White: Step by Step

1. Preheat your cup

Run a small amount of hot water into your cup and let it sit while you prepare everything else. A cold ceramic cup drops the temperature of a small drink noticeably, and a flat white has very little thermal mass to spare.

2. Dose and tamp

Dose 16 to 18 g of freshly ground coffee into your portafilter. Distribute evenly, then tamp with firm, level pressure (around 30 lbs / 14 kg). Uneven tamping causes channeling, where water finds a path of least resistance through the puck and produces a thin, sour shot.

3. Pull the espresso

Lock in the portafilter and pull your shot. For a ristretto-style flat white, stop the shot at 24 to 28 ml; for a standard double, aim for 32 to 36 ml. Both work. The ristretto yields a sweeter, more concentrated base with less bitter edge; the double espresso produces a more familiar character. Try both and see which suits you.

Brew temperature should be in the range of 195 to 205°F (90 to 96°C), which most home machines handle automatically.

4. Steam the milk

Pour approximately 100 to 110 ml of cold whole milk into your steaming pitcher. Submerge the steam wand tip just below the milk surface at a slight angle so the milk starts to spin in a slow whirlpool.

Open the steam valve fully and hold the tip just at the surface for the first few seconds. You want to hear a soft, papery hiss rather than a loud, airy screech. That quiet hiss means you are incorporating small amounts of air to stretch the milk rather than blowing large bubbles into it. Once you hear that sound, lower the pitcher very slightly so the tip is about half an inch (1 to 1.5 cm) below the surface. Let the spinning motion do the work.

Pull the wand away when the milk reaches 140 to 150°F (60 to 65°C). If you do not have a thermometer, use the side of the pitcher: when it becomes uncomfortably hot to hold for more than a couple of seconds, you are close to target temperature. Milk above 160°F / 71°C starts to taste scalded and loses sweetness.

5. Texture the milk

After steaming, knock the pitcher gently on the counter once or twice to pop any large bubbles, then swirl it in a circular motion for 10 to 15 seconds. The milk should look glossy and slightly thickened, with no visible bubbles on the surface. If you see large bubbles, the milk is too foamy for a flat white; adjust the wand position next time so the tip sits deeper in the milk during stretching.

6. Pour

Empty the preheating water from your cup. Pour the espresso directly in. Hold the pitcher low over the cup and pour the milk in a slow, steady stream, starting in the center. Tilt the cup slightly toward you if it helps you control the pour. The finished drink should show a thin white surface with very little foam height, ideally under 5 mm.

You will have a small amount of milk left in the pitcher. That is correct; you cannot pour every last drop and maintain control.

Adjusting the Recipe

If your flat white tastes too bitter, try a slightly coarser grind, pull the shot a second or two shorter, or switch to a lighter roast. If it tastes sour or thin, grind finer or let the shot run a couple of seconds longer. Milk drinks are forgiving of minor espresso variation, but a badly channeled shot with a pale, blond crema will show through even in a milk drink this small.

For comparison, a cortado sits even smaller (about 4 oz total) with a nearly 1:1 espresso-to-milk ratio and no foam stretching required. It is a good next step once the flat white feels comfortable.

Frequently Asked Questions

Can I make a flat white without an espresso machine?

Not authentically. The flat white depends on pressurized espresso extraction and a steam wand for microfoam. A Moka pot produces a strong concentrate but lacks the crema and body of a true espresso, and it cannot produce the milk texture needed. If you want to experiment, a Moka pot paired with a handheld milk frother can approximate the flavor, though the texture will be noticeably different.

What milk is best for a flat white?

Whole milk produces the most stable, naturally sweet microfoam because of its fat content. 2% milk works but produces slightly less body. Barista-grade oat milk is the most reliable non-dairy option; it froths well and has a flavor that pairs cleanly with espresso. Almond and coconut milk tend to produce thinner foam that breaks more quickly.

What is the correct flat white ratio?

A traditional flat white uses about 25 to 30 ml of espresso (a double ristretto) and 100 to 110 ml of steamed milk with minimal foam, for a total of roughly 130 to 140 ml in a 5 to 5.5 oz cup. Some cafes run the ratio slightly looser, but if you go past 160 ml total, you are making a small latte rather than a flat white.

How is a flat white different from a cappuccino?

A cappuccino is traditionally made in three equal parts: espresso, steamed milk, and milk foam. The foam layer on a cappuccino is thick and dry (or silky in a wet cappuccino). A flat white has almost no foam, a smaller total volume, and a higher espresso-to-milk ratio. The cappuccino is lighter and airier; the flat white is denser and stronger.

Can I make an iced version?

Yes, though it changes the character considerably. Pull your double ristretto over ice in a small glass, then add cold milk (no steaming needed) to fill. The result is closer to an iced latte in texture, since you cannot replicate microfoam over ice. It is refreshing, but the flat white's defining silkiness comes from the steamed milk, so the iced version is its own drink rather than a direct substitute.
