Quick answer: A flat white is a double ristretto (approximately 40ml of concentrated espresso) topped with 90-100ml of steamed milk with very fine microfoam — thinner and silkier than a latte, smaller and more intense. Getting it right at home requires a machine with a steam wand, a burr grinder, and about a week of practice. Here’s the complete process.
🔗 Need a machine first? A flat white requires a steam wand — bean-to-cup and capsule machines without one won’t work for this. See our machine guide — the Sage Bambino Plus with its automatic steam wand is the easiest machine for flat whites as a beginner.
What Makes a Flat White Different from a Latte
A flat white originated in Australia and New Zealand in the 1980s and is defined by three things: a smaller total volume (around 130-150ml), a double ristretto base (shorter, more concentrated than a standard double espresso), and very thin microfoam — sometimes called “velvet” milk — that integrates with the espresso rather than sitting on top of it.
A latte typically uses a standard double espresso, has more milk (180-220ml), and has a slightly thicker foam layer. The flat white is more intense, smaller, and the coffee-to-milk ratio is higher — you taste the espresso more clearly.
What You Need
- An espresso machine with a steam wand — manual or automatic. The Sage Bambino Plus automatic steam wand is ideal for beginners.
- A burr grinder — essential for consistent espresso. See our grinder guide.
- Fresh whole milk — full fat produces the best microfoam. Oat milk works well as a dairy alternative (Oatly Barista is the standard recommendation).
- A small steaming jug — 300-350ml is ideal for a flat white.
- A kitchen scale — for weighing your espresso yield.
The Flat White Recipe
Dose: 18g coffee in
Yield: 36-40ml espresso out (1:2 to 1:2.2 ratio — slightly shorter than standard)
Extraction time: 25-30 seconds
Milk: 90-100ml steamed to 60-65°C with very fine microfoam
Total volume: approximately 130-140ml
Step by Step
Pull Your Ristretto
Grind 18g of coffee on a fine setting. Dose into the portafilter, tamp evenly with approximately 15kg of pressure. Lock in and extract. Target 36-40ml of espresso in 25-30 seconds. If it runs fast, grind finer. If slow, grind coarser. See our grind size guide for the full troubleshooting process.
Prepare Your Milk
Pour 100-110ml of cold full-fat milk into your steaming jug. Cold milk gives you more time to work before it overheats. Purge the steam wand briefly to clear any water from the tip.
Steam the Milk — The Critical Step
Submerge the steam wand tip just below the milk surface and tilt the jug slightly to create a clockwise whirlpool. For a flat white, you want very minimal aeration — introduce air for only the first 2-3 seconds, then submerge the tip slightly deeper and let the whirlpool integrate the foam. Target temperature is 60-65°C — hot enough to drink comfortably, not so hot the milk scorches and turns sweet. If you don’t have a thermometer, stop when the jug becomes too hot to hold comfortably for more than 3 seconds.
The finished milk should look glossy and slightly thicker than before steaming — like wet paint. Tap the jug firmly on the counter to burst any large bubbles, then swirl vigorously.
Pour
Hold the jug close to the cup surface and pour steadily through the centre of the espresso. The milk and coffee should blend naturally. As the cup fills, raise the jug slightly and pour a little faster to bring the foam to the surface. A flat white has a thin white circle on top — not a thick dome of foam. If you’re practicing latte art, the flat white’s thin microfoam is actually easier to work with than latte foam once you have the technique.
Common Problems and Fixes
- Milk too frothy / bubbly — you introduced too much air during steaming. Keep the wand tip just below the surface for a shorter time, or submerge it more quickly.
- Milk separating or curdling — overheated. Stop at 65°C maximum. Scorched milk tastes unpleasantly sweet and won’t integrate with the espresso.
- Espresso too bitter — grind coarser or reduce your extraction yield slightly. A ristretto that’s too long tastes bitter. See our espresso technique guide.
- Flat white tastes weak — grind finer or use more coffee. Check your dose is 18g and your yield isn’t exceeding 45ml.
The Machine Matters
The steam wand makes a significant difference to flat white quality. The Sage Bambino Plus at £399 has an automatic steam wand that handles the aeration and temperature automatically — it produces consistently good flat white milk without the learning curve. The Barista Express and Barista Pro both have manual wands with higher quality ceilings once you develop technique. See our complete milk steaming guide for wand technique in detail.
How Long Will It Take to Make a Good Flat White at Home?
Realistically, one to two weeks of daily practice. The espresso dialling in comes first — once your shots are consistent (25-30 seconds, good crema), the milk technique follows. The flat white’s thin microfoam requirement is actually more forgiving than cappuccino foam once you understand the wand position — it’s a gentler technique that rewards patience over force.
Most home baristas who practice daily report being happy with their flat whites within 10-15 attempts. The first few will be rough — that’s normal and expected. Keep notes on grind settings and milk technique, adjust one variable at a time, and the results improve quickly.
Frequently Asked Questions
What is the difference between a flat white and a latte?
A flat white is smaller (130-150ml vs 180-220ml), uses a double ristretto rather than a standard double espresso, and has thinner microfoam that fully integrates with the milk. The result is a more intense, coffee-forward drink with a silkier texture. A latte has more milk, a slightly thicker foam layer, and a milder coffee flavour. Both use steamed milk — the difference is volume, espresso concentration, and foam texture.
Can I make a flat white with a Nespresso machine?
With limitations. A Nespresso Original Line machine produces acceptable espresso for a flat white, though it won’t reach the intensity of a double ristretto from a semi-automatic machine. You’ll need a separate frother — the Aeroccino 4 is the best option. The result will be a decent milk coffee rather than a precise flat white, but entirely drinkable. See our milk frother guide for the best frother options.
What milk is best for a flat white?
Full-fat whole milk produces the best microfoam — the fat content creates the glossy, integrated texture characteristic of a good flat white. Semi-skimmed works but produces slightly less stable foam. For plant-based alternatives, Oatly Barista Edition is the standard recommendation — it steams similarly to whole milk and produces good microfoam. Avoid standard oat milk or almond milk, which don’t steam well and can separate.
What temperature should a flat white be served at?
60-65°C is the standard target — hot enough to drink immediately, cool enough not to scorch the milk or burn your mouth. Above 70°C milk proteins break down and the milk tastes overly sweet and flat. A simple milk thermometer (~£8 on Amazon) is the easiest way to hit this consistently while you’re learning.
