A flat white combines espresso with steamed milk and is associated with Australian and New Zealand café culture. Compared with many latte presentations, it is often served in a smaller format with fine, integrated milk texture. Those are useful tendencies, not a recipe enforced identically around the world.
The amount of espresso, beverage size and milk texture determine the drink more precisely than its name alone. A café may prepare its flat white differently from the version familiar to a customer. Ask about the serving if the coffee-to-milk balance matters to your order.
At home, keep the espresso and milk quantities recorded so the result can be repeated. Aim for a texture appropriate to the drink rather than adding a separate mound of foam merely for appearance. Compare the cup as it cools and adjust according to preference. A stronger coffee impression can come from changing the ratio, without requiring a blanket rule about a particular bean or roast.
