Introduction:Flat White, a milk-based coffee that has garnered significant attention in recent years, originated in Melbourne, Australia in the 1980s and developed its own distinctive flavor profile in New Zealand. This article delves into its core differences from Latte and Cappuccino, explores the extraction logic of Ristretto and regular espresso, and combines practical brewing parameters with flavor evaluations to help you master the essence of this “miniature Latte.” We cover everything from bean selection to milk foam thickness.

Walk into a modern café, and Flat White has become a staple on the espresso menu. This beverage, which originated in Melbourne, Australia in the 1980s, later flourished in New Zealand, driving the milk coffee culture across the Australasian region. Compared to Latte and Cappuccino, Flat White is most distinctly characterized by its thinner layer of milk foam and higher coffee concentration, resulting in a balanced and rich drinking experience.

Regarding the name, "Fulai White" is one of the common Chinese translations for Flat White. Interestingly, Starbucks adopts the New Zealand approach, using a double Ristretto as the base, while the Australian version often uses a single shot of espresso, offering a flavor closer to Latte but with finer and denser milk foam. These differences give the same drink diverse expressions across regions.

Ristretto is the first key to understanding Flat White. This extraction method achieves its results by shortening the brew time (approximately 23–25 seconds) and reducing the liquid output (about 30 ml extracted from 20 g of coffee grounds), extracting only the first, most essential part of the coffee — small molecules rich in bright acidity and fruity, floral notes. Compared to a regular espresso (40 ml / 40 g of coffee / 25–30 seconds), Ristretto has less bitterness, higher concentration, and a more focused flavor.

When actually making a Flat White, it is recommended to use a coffee-to-milk ratio of 1:1.6 to 1:1.7, with the milk temperature controlled at 55–60°C for optimal taste. Taking a double Ristretto as an example: using 20 g of coffee grounds to extract 30 ml of espresso (in about 25 seconds), paired with 145 ml of steamed milk. This combination highlights a distinct cocoa and dark chocolate profile, with a mellow sweet finish of roasted hazelnuts and almonds.

Milk foam handling is the key to success. The milk foam in a Flat White is only about 2–3 mm thick and needs to be smoother and finer than that of a Latte in order to complement the crema of the espresso. The angle and steam pressure of the steam wand are crucial — it is recommended to maintain the milk temperature within the 55–60°C range, as overheating can disrupt the delicate flavor balance.

In terms of coffee bean selection, darker roasts can enhance the expression of crema and layered flavors. It is recommended to choose medium-dark to dark roast blends, such as those containing beans from Brazil, Indonesia, or other regions — these types of beans offer a stable caramel base and a rich mouthfeel. Avoid using light roasts to prevent thin acidity from disrupting overall balance. The ideal crema should exhibit a golden-yellow sheen and good persistence, which is an important indicator of successful extraction.

In summary, the charm of Flat White lies in precise espresso extraction, perfectly judged milk foam thickness, and the harmonious proportions among the components. Whether choosing a single or double Ristretto, the focus is on highlighting the layered characteristics of the coffee itself, while letting the milk play a supporting rather than dominant role. Mastering these essentials allows you to recreate a professional-grade Flat White experience at home.
