Introduction:Flat White, as one of the representatives of specialty coffee, has gained increasing popularity among coffee enthusiasts in recent years. But what sets it apart from a latte or cappuccino? From coffee concentration and milk foam thickness to optimal extraction parameters, this article delves into the origins, recipe details, and flavor differences between Flat White, Starbucks’ Blonde Roast (馥芮白), and latte, helping you master the brewing techniques and tasting points of this classic coffee.
With the rise of specialty coffee culture, Flat White has become one of the classic beverages offered by many cafés. Although it belongs to the milk coffee category along with latte and cappuccino, its flavor profile is distinctly different. Many customers often wonder, if they all consist of coffee and milk, what’s the difference between Flat White and latte? In fact, the hallmark of Flat White lies in its smaller amount of milk and more intense coffee expression, allowing drinkers to clearly perceive the layers of espresso and the integration with delicate milk foam.
What is Flat White?Simply put, it combines a double shot of ristretto espresso with a small amount of microfoamed fresh milk. The milk foam is only about 5 mm thick—finer than that of a latte and smoother than that of a cappuccino. This beverage emphasizes the richness of the coffee and the silky, velvety texture of the milk, making it ideal for those who prefer a coffee-forward taste. When preparing it, a blend of Ethiopian Natural Red Cherry and Honduran Sherry beans is commonly used. The resulting espresso boasts notes of wine, fruit acidity, and a nutty aftertaste, which, when combined with milk, presents a milkshake-like sweetness while still retaining the character of the coffee.
The birthplace of Flat White is debated, with some claiming it originated in Melbourne in the 1970s and others attributing it to Sydney in the 1980s. Regardless of its origin, Australian coffee culture is deeply influenced by Europe, particularly the espresso tradition brought by Italian immigrants. On the streets of Australia, nearly every café offers high-quality milk coffee. Due to the fast-paced lifestyle and widespread coffee consumption, locals prefer drinks with a concentrated flavor and moderate milk content, which contributed to the gradual formation of Flat White as a style characterized by “small serving size, low foam, and espresso dominance.”
Notably, the international promotion of Flat White is closely tied to Starbucks introducing it to the global market in the 2010s. Starbucks translated it as “Blonde Roast” (馥芮白), and it quickly became a favorite among many consumers. However, compared to a regular latte, Blonde Roast uses less milk and a more concentrated coffee base, resulting in an overall tighter and more layered taste. In contrast, a latte has thicker foam (about 1 cm), a higher proportion of milk, and a softer, smoother mouthfeel.
In terms of preparation,the standard ratio for Flat White is: a double shot of espresso (approximately 40 ml) paired with 140 ml of whole fresh milk, for a total volume of about 180–200 ml, served in a smaller ceramic cup to maintain the drink’s temperature and aroma. The milk should be steamed to a temperature of 55–60°C, a range that fully releases the sweetness of lactose without damaging the protein structure, which could result in a rough texture. The milk foam layer must be extremely fine, with a thickness of only about 0.3 cm, creating a silky-smooth mouthfeel.
Common extraction parameters can be referenced as follows: using 9 bar pressure, an extraction temperature of about 94°C, a coffee-to-water ratio between 1:1.7 and 1:2, and an extraction time of 20–30 seconds. For a single shot of espresso, 12 grams of coffee grounds can be used to yield about 20 ml; for a double shot, it is recommended to use 20 grams of coffee grounds to produce around 40 ml of ristretto espresso. This type of espresso not only has rich crema but also supports the overall flavor performance when blended with milk.
In terms of flavor characteristics, a well-made Flat White should have a rich yet not heavy coffee aroma, paired with silky milk foam. Upon tasting, one can feel the delicate microfoam texture, accompanied by berry acidity and chocolate or vanilla undertones. Some baristas also emphasize that using a single-origin espresso (SOE) can more clearly highlight the terroir characteristics of the origin, subtly interacting with the lactose aroma of the milk to create a unique flavor layer.
In summary, the charm of Flat White lies in its balance of “richness without bitterness, smoothness without thinness.” Whether you’re a beginner coffee enthusiast or someone looking to deeply understand the differences among various milk coffees, mastering the recipe and technical details of Flat White will allow you to better appreciate this classic espresso-based drink that originated in Australia and has captivated the world. From milk foam thickness, coffee ratio, to extraction parameters, every aspect influences the final flavor profile—and is a key focus for professional baristas striving for continuous improvement.
