What Makes a Flat White Different?

Before diving into technique, it is worth being clear about what separates a flat white from a latte or a cappuccino. The distinction is not just about size, it is about the ratio of coffee to milk and the texture of the foam itself.

A flat white is typically served in a 140 to 180ml cup. Compare that to a latte, which is usually 240 to 300ml, and you immediately understand why the flat white tastes more intense. The same double espresso base is present in both drinks, but in a flat white it is not diluted by the same volume of milk. The result is a drink with a stronger coffee character, a creamier mouthfeel, and a much thinner layer of microfoam sitting flush with the rim of the cup. That last detail is where the name comes from: the foam is flat.

Get these fundamentals right and everything else follows naturally.

Step 1: Pulling the Espresso Base

A flat white lives or dies on the quality of its espresso. Because the milk volume is relatively low, there is nowhere to hide a poorly extracted shot. Sourness, bitterness, and thin body all become immediately apparent in the cup.

Understanding Espresso Ratios

Espresso ratios describe the relationship between the dry weight of coffee you put into the portafilter and the liquid weight you collect in the cup. There are three common ratios to understand:

• Ristretto (1:1 to 1:1.5): A shorter, more concentrated extraction. Naturally sweeter and less bitter, which makes it an excellent base for milk drinks. The reduced yield means the espresso flavour punches through the milk with real clarity.
• Espresso (1:2): The standard starting point for most home baristas. If you dose 18 grams of coffee, you are aiming for approximately 36 grams of liquid in the cup. Balanced, versatile, and forgiving.
• Lungo (1:2.5 to 1:3): A longer pull that extracts more from the coffee bed. Can introduce bitterness if pushed too far, and tends to produce a thinner body that can get lost behind the milk in a flat white.

For a flat white, a standard 1:2 espresso or a tighter ristretto-style pull both work well. The right choice depends on your beans and your personal preference. Start at 1:2 and adjust from there once you have a baseline you can taste and evaluate.

Extraction Time and Grind Size

Aim for an extraction time of 25 to 35 seconds for a standard espresso ratio. If your shot runs faster than this, your grind is too coarse and the water is passing through the coffee bed without extracting enough. If it runs slower, your grind is too fine and the water is struggling to push through. Adjust in small increments and taste after every change.

Freshness matters enormously here. Coffee that has been sitting in a bag for months will extract inconsistently regardless of your grind setting. At Scorgo, we roast to order specifically to avoid this problem. For espresso, we recommend brewing between five and twenty-one days after the roast date to allow the beans to degas without losing their aromatic complexity.

Step 2: Choosing the Right Cup

Cup size is not a minor detail in a flat white. It directly determines the ratio of coffee to milk in the finished drink, which in turn defines the flavour balance you experience.

A traditional flat white is served in a 140 to 180ml vessel. This is considerably smaller than a standard latte glass and is the key reason the drink tastes so much more coffee-forward. If you use a larger cup, you will need to add more milk to fill it, which dilutes the espresso and shifts the drink closer to a latte in character.

A 6oz (approximately 180ml) cup with a double espresso is a practical and widely used format that delivers the right balance of strength and creaminess. If you are brewing at home and do not own a dedicated flat white cup, a small ceramic mug in the 150 to 180ml range works perfectly well. Our Scorgo Ceramic Coffee Mug is a solid choice for home brewing, offering a comfortable size and excellent heat retention.

Step 3: Mastering Flat White Microfoam

This is where most home baristas either nail the flat white or fall short of it. The milk texture in a flat white is fundamentally different from a cappuccino. There is no thick, pillowy foam sitting on top. The microfoam should be so fine and so well integrated that it is almost indistinguishable from the milk itself, producing a glossy, paint-like consistency that pours smoothly and blends seamlessly with the espresso.

The Aeration Phase

Start with cold milk straight from the fridge. This gives you more time to work before the milk reaches its target temperature. Position the tip of the steam wand just at the surface of the milk and open the steam valve fully. You are listening for a soft, consistent sound, often described as paper tearing or quiet hissing. This is the sound of air being drawn into the milk.

For a flat white, you want a modest increase in volume during this phase, roughly 20 to 25 percent. Any more than this and you will end up with foam that is too thick and airy for the drink. The aeration phase should be complete by the time the milk reaches body temperature, around 37 degrees Celsius. After that point, you are no longer adding air effectively.

The Texturing Phase

Once you have introduced enough air, submerge the wand tip slightly deeper and tilt the jug to create a rolling vortex. This is the phase that transforms large, unstable bubbles into the microscopic particles that define true microfoam. The milk should spin in a consistent whirlpool, folding the foam back into the liquid continuously until the surface appears glossy and smooth.

Target a final temperature of 60 to 65 degrees Celsius. Beyond 68 degrees, the proteins in the milk break down permanently, the natural sweetness disappears, and you are left with a flat, slightly cooked flavour that no amount of good espresso can rescue.

Common Mistakes to Avoid

• Too much air: The foam becomes thick and frothy rather than silky. It will sit on top of the espresso rather than integrating with it, and the drink will feel more like a cappuccino.
• Too little air: The milk heats up without developing any texture. You end up with hot, thin milk that lacks the creaminess a flat white requires.
• Stopping the vortex too early: Large bubbles that are not broken down during the texturing phase will rise to the surface and create an uneven, bubbly pour.
• Overheating: Once you go past 68 degrees, there is no recovery. The milk must be discarded and you start again.

Step 4: Choosing the Right Coffee Beans

There is no single correct bean for a flat white, but there are choices that make the process considerably more enjoyable and the result considerably more satisfying.

Medium Roast Blends for Richness and Consistency

If you are new to making flat whites at home, a medium roast blend is the most forgiving starting point. The flavour profile, typically chocolate, caramel, toasted nuts, or brown sugar, holds up beautifully behind milk and remains recognisable even when the espresso is slightly off in either direction. The lower acidity also means the drink stays balanced rather than turning sharp or sour if your extraction is not perfectly dialled in.

Our Number 14 Signature Blend, a Brazil and Colombia combination, is an excellent choice here. It delivers a rich, sweet espresso with good body that integrates naturally with steamed milk. Similarly, the Number 82 Prestige Blend, combining Brazil and Uganda, offers a more complex cup with a deeper, earthier sweetness that works particularly well in a ristretto-style flat white.

You can explore the full range of blends in our Signature Collection and Prestige Collection.

Single-Origin Coffees for a More Expressive Cup

If you are comfortable with your extraction and want to push the flat white into more interesting territory, single-origin coffees open up a genuinely different experience. Lighter, fruitier profiles can produce flat whites with a brightness and complexity that blends simply cannot replicate. The trade-off is that they require more precise dialling in and are less forgiving of extraction errors.

Our Number 9 Guatemala is a particularly good option for flat whites, offering a clean, balanced cup with gentle sweetness that complements rather than fights the milk. For something with a little more character, the Number 19 Colombia brings a naturally sweet, well-rounded profile that holds up well in smaller milk-based drinks. If you enjoy a brighter, more fruit-forward flat white, the Number 8 Ethiopia is worth exploring, though it rewards careful extraction.

Step 5: No Espresso Machine? Here Is What to Do

Not everyone has a home espresso machine, and that should not stop you from making a genuinely good flat white. The key is producing a concentrated coffee base that can hold its own against the milk.

The AeroPress Method

The AeroPress is one of the most versatile brewing tools available and, when used with a fine grind and a short brew time, produces a concentrated, espresso-adjacent coffee that works very well as a flat white base. Use approximately 18 to 20 grams of finely ground coffee with around 40 to 50ml of water at 90 to 94 degrees Celsius. Press slowly and deliberately for a rich, full-bodied result.

Our AeroPress Original is ideal for home use, while the AeroPress Go is a compact travel version that fits neatly into a bag for brewing on the move. Pair either with our AeroPress Filter Papers for a clean, sediment-free cup. You can find all AeroPress equipment in our dedicated AeroPress collection.

The Moka Pot Method

A moka pot produces a strong, bold coffee with a heavier body than filter but without the true pressure of an espresso machine. It is not technically espresso, but it is concentrated enough to work in a flat white when paired with well-textured milk. Use a fine-to-medium grind, do not pack the basket tightly, and remove the pot from the heat as soon as the coffee begins to flow to avoid bitterness.

For the milk, a handheld electric frother or a dedicated steaming device will get you close enough to microfoam for a satisfying result at home.

The Simple Flat White Recipe

Once you have your equipment and beans sorted, the process itself is straightforward. Here is a clean, repeatable recipe to follow:

1. Grind 18 grams of fresh coffee to a fine espresso setting.
2. Pull a double espresso at a 1:2 ratio, targeting 36 grams of liquid in 25 to 35 seconds.
3. Pour cold milk into your serving cup to just below the rim, then transfer it to your steaming jug. This ensures you use exactly the right amount.
4. Steam the milk, introducing a modest amount of air during the first few seconds, then rolling it into a vortex until smooth and glossy. Target 60 to 65 degrees Celsius.
5. Tap the jug on the counter and swirl to integrate any remaining surface bubbles.
6. Pour the milk into the espresso in a 140 to 180ml cup, starting slightly higher to allow the milk to flow under the crema, then bringing the jug closer to the surface as the cup fills.

The finished drink should be rich, balanced, and creamy, with a strong coffee character and a smooth mouthfeel. The microfoam should sit flush with the rim rather than mounding above it.
