Introduction:Have you ever wondered what exactly sets a Flat White apart from a Caffè Latte? Many assume it’s just the difference in milk foam thickness, but in reality, these two classic milk-based coffees differ significantly in cup size, extraction ratio, milk foam texture, and even the ideal way to enjoy them. This article will take an in-depth look at the preparation parameters and core distinctions between a Flat White and a Caffè Latte, along with tips for home brewing and manual preparation, helping you better appreciate the unique charm of these two popular coffee drinks.

Flat White, commonly known as Australian-style milk coffee, is a classic Italian-style milk coffee originating from Australia and New Zealand. In recent years, it has gained a large following around the world. Many people often confuse Flat White with Caffè Latte when ordering at cafes, but in truth, there are systematic differences between them. From cup size, number of espresso shots used, milk foam thickness, to overall flavor profile and recommended drinking method, each has its own characteristics.

The origin of the Flat White has long been debated—some believe it was born in Australia, while others claim it’s a New Zealand innovation. However, it’s certain that this coffee drink rose to prominence in the 1980s, at a time when the café culture in Australia and New Zealand already had a mature Italian coffee scene, but customers were beginning to seek a more refined milk coffee experience with a stronger coffee presence. To meet this demand, baristas utilized the region’s abundant supply of fresh milk and skilled steaming techniques to create the Flat White, which features extremely fine micro-foam that drapes smoothly and velvety over the surface of the coffee.

In the standard preparation, a Flat White is typically served in a cup of about 200ml, with two shots of espresso (around 40g of coffee grounds extracted), and the milk foam is controlled to a thickness of approximately 0.5cm. The crema layer on the coffee surface is preserved as much as possible, so that the first sip delivers a strong, rich coffee flavor. This combination gives the Flat White a more pronounced coffee taste than a latte, while also offering a smooth and delicate mouthfeel.

In comparison, a Caffè Latte is served in a larger cup, usually 300ml, also using two espresso shots, but the milk foam is about 1cm thick, and latte art is often poured after the milk. The milk foam in a latte is fluffier, and when mixed with the coffee, results in a creamier, more milk-forward overall flavor—making it ideal for those who prefer a milk-dominant drink.

From an extraction perspective, most cafes use professional espresso machines, extracting espresso under about 9–10 bars of pressure, using water heated to around 94°C passed through finely ground coffee, achieving a brew ratio of approximately 1:2 (grounds to liquid). This espresso serves as the foundation for all Italian-style milk coffees and is key to the final flavor profile.

To recreate an authentic Flat White at home, it’s recommended to use a home semi-automatic espresso machine or a manual espresso tool. For instance, when using a hand-operated coffee press, you can try using 18g of very finely ground coffee with 120ml of water heated to about 95°C to extract 40ml of espresso. Then, heat the milk to 55–65°C, froth it with a milk frother, remove the larger bubbles on top to reduce the foam thickness to about 0.5cm, gently swirl the pitcher to evenly mix the foam with the milk, and finally pour slowly from the center of the espresso. The total drink volume should be around 200ml.

So why is the Flat White generally only served hot? This is closely related to the characteristics of its milk foam and the overall drinking experience. Because the milk foam in a Flat White is very fine and relatively thin, it can only maintain its smooth texture at an appropriate temperature, allowing each sip to blend the foam with the rich coffee underneath. Adding ice not only dilutes the coffee flavor, but also easily destabilizes the foam, affecting the overall mouthfeel. Therefore, to deliver the best flavor, most cafes offer the Flat White only in a hot version.

If you prefer an iced, intense milk coffee, you might consider ordering a ‘Dirty’ instead. This drink involves pouring freshly extracted hot espresso directly into cold fresh milk, creating a striking contrast of temperatures and visual appeal, while still delivering a rich and layered coffee experience.

When selecting coffee beans suitable for making a Flat White, it’s recommended to prioritize blends with high stability and balanced flavors. Due to the differences in extraction conditions between home and commercial espresso machines, choosing a medium-to-dark roasted blend with consistent flavor and a higher margin for error can help improve your chances of a successful extraction. Common blends are often based on Brazilian beans, combined with other origins such as Colombia, Yunnan, or a small amount of Robusta to enhance body and aroma.

For example, a common specialty blend might combine 30% Colombian washed beans with 70% Brazilian natural sundried beans, offering flavors of chocolate, caramel, and creaminess. When paired with hot milk, it delivers a rich, dessert-like taste similar to unsweetened Ovaltine. Another classic commercial blend might include a small amount of Robusta (10%), 30% Colombian, and 60% Brazilian beans, producing bold crema and nutty aromas. It has a noticeable bitterness that quickly transitions into a smooth, milky aftertaste.

Many baristas also recommend using mildly acidic yet full-bodied blends, such as a combination of 30% Yunnan small-bean coffee and 70% Brazilian natural sundried beans. This offers soft plum acidity and nutty tones, resulting in a balanced and smooth mouthfeel when mixed with milk—ideal for those who enjoy complex flavor layers.

In summary, although both Flat White and Caffè Latte are Italian-style milk coffees, they differ significantly in cup size, milk foam thickness, espresso ratio, and overall flavor profile. Understanding these details not only helps you make more informed choices at cafes, but also provides clear guidance for home brewing, allowing you to enjoy a professional-grade Flat White in the comfort of your own home.
