What Makes a Great Flat White?

Quick answer

A great flat white is a strong espresso with a thin layer of silky microfoam blended in, with roughly 1 part espresso to 2 or 3 parts milk. The milk should be glossy with no stiff foam on top and not overheated; about 130 to 135 F keeps its sweetness. Cup size varies by cafe.

What makes a great flat white?

Three things: good espresso, silky microfoam and the right balance. A flat white is espresso combined with steamed milk textured into very fine bubbles, so the drink tastes more of coffee than a latte does.

What is the right ratio?

About 1 part espresso to 2 or 3 parts milk. A latte is closer to 1 to 3 or more, so a flat white is stronger. One coffee guide says a flat white is typically made with a double ristretto (about 1 oz) and about 4 oz of steamed milk. There is no single official recipe, so cup size varies by cafe.

How should the milk feel?

The milk should be glossy, with bubbles too fine to see, blended fully with the espresso and without a stiff foam layer on top. If it looks foamy like a cappuccino, it is not a flat white. Add air while the milk is still cool, using short bursts with the steam wand.

What temperature?

One barista guide gives about 130 to 135 F (54 to 57 C) and says milk should not be steamed above 135 F because the milk sugars break down. Never let milk boil.

Drink Milk and foam Strength
Flat white Thin microfoam, blended Strong
Latte More milk, light foam on top Milder
Cappuccino Distinct thick foam layer Varies by cafe

Checklist for making one at home

  • Use fresh beans and a good grind, and extract a balanced shot.
  • Use cold milk and a cold jug.
  • Pour slowly, bringing the jug close to the cup.
  • Serve at once; microfoam separates quickly.

Where did it start?

The earliest known menu listing is from 1980s Sydney, though New Zealand also claims the drink, and the origin is debated.

Taste is personal; adjust the ratio and milk to what you like.
