Latte vs. flat white

Same espresso, different dilution

CoffeeHQ explanation

Think of both drinks as espresso diluted with milk. If two drinks start from the same shot and one adds roughly 120 ml of milk while the other adds roughly 200 ml, the first is a noticeably more concentrated coffee drink. Nothing about the coffee has changed; there is simply less milk between you and it.

This is why a flat white is often described as stronger. It does not contain more caffeine than a latte made with the same shots. It tastes stronger because the coffee makes up a larger share of the cup.

Where the name comes from

Widely documented

The second difference is texture. For a flat white the milk is steamed with very little air, giving a thin, glossy microfoam that blends into the drink instead of sitting on it. The surface is level with the rim and has no dome, which is the usual explanation for the word flat.

A latte's milk is stretched a little more, leaving a slightly deeper layer of foam on top of a larger body of warm milk. In practice many cafés steam both the same way and let the size of the cup do the work.

What you are likely to be handed

Typical range

These describe common practice, not a standard. There is no governing definition of either drink, and chain-café sizes can be far larger than the ranges here.

Who invented the flat white

Accounts differ

The flat white emerged in Australia and New Zealand in the 1980s, and both countries claim it. Several cafés and individuals have been credited, and no documentary evidence settles the question. What is clear is that it spread internationally from the 2000s onwards and that its definition loosened as it travelled.

If you are making them at home

CoffeeHQ explanation

Your flat white tastes like a small latte

Usually because: Too much air went into the milk, so there is a foam cap instead of an integrated texture.

Change first: Introduce air for only a second or two, then keep the tip under the surface.

Making microfoam

Your latte tastes weak and milky

Usually because: One shot is being asked to flavour a large volume of milk.

Change first: Use a double shot, or a smaller cup, before changing the coffee.
