Introduction:Want to learn how to make a Starbucks Flat White, or figure out the difference between a Flat White and a Latte? This article provides an in-depth analysis of the definitions, historical origins, and flavor profiles of Flat White (Australian-style), Piccolo (short latte), Latte, and Cappuccino, along with professional extraction and milk frothing parameters—helping you brew a rich and distinctive espresso-based milk drink at home.

In today’s era of growing specialty coffee popularity, milk-based coffee is no longer just a caffeine booster but also an important medium for appreciating layers of coffee flavors. Among them, Flat White (commonly translated as Australian-style, Little White Coffee, Flat Art White, or馥芮白) is a milk coffee originating from Oceania that has sparked a global trend due to its thinner milk foam and more pronounced coffee flavor. But what exactly is a Flat White? How does it differ from common lattes, cappuccinos, and even Piccolo Lattes? This article will comprehensively break down the distinctions among these popular milk coffees, and share precise coffee-to-milk ratios, extraction, and milk frothing parameters—so you can recreate café-quality flavors at home.

First, let’s clarify a common question—what exactly is a Flat White? In Chinese, Flat White has various translations such as “澳白咖啡” (Australian White Coffee), “小白咖啡,” “馥芮白,” “醇藝白,” or “澳芮白.” However, it is actually a milk coffee that originated in Australia (some say New Zealand). Though its birthplace is debated, its definition and preparation method are largely consistent: characterized by a smaller amount of milk, ultra-thin milk foam, and a finely extracted coffee base, making the coffee flavors more direct and pronounced. It’s worth noting that baristas in New Zealand typically use a double ristretto shot, while those in Australia prefer a single espresso as the base.

So, how does a Flat White differ from the more familiar Latte and Cappuccino? In terms of milk foam thickness, the Cappuccino has the thickest foam (about 1–1.5 cm), often featuring the iconic “11 o’clock full” burger-like shape; the Latte falls in the middle (around 0.5 cm), is suitable for latte art, and has a more prominent milk flavor; while the Flat White has the thinnest foam (about 0.3 cm), nearly level with the rim of the cup, hence it’s also nicknamed the “flat white coffee.” In terms of volume, a standard Latte is around 300 ml, a Cappuccino about 180 ml, while a Flat White is roughly 210 ml. Additionally, Cappuccinos and Flat Whites traditionally do not come in iced versions, whereas Lattes are available both hot and cold.

The popularity of these three milk coffees is not only due to their representation of different flavor preferences, but also reflects modern consumers' increasing demand for coffee quality. Especially the Flat White, with its relatively small amount of milk and foam, places higher demands on the coffee bean's ability to express its flavor. Choosing a high-quality single-origin SOE (Single Origin Espresso) can further highlight the regional characteristics and processing method flavors of the beans, which aligns with the core philosophy of the current third wave of coffee that emphasizes “traceability” and “refinement.”

Besides the three common milk coffees mentioned above, the Piccolo Latte is also a must-try item on many coffee lovers’ lists. “Piccolo” means “small” in Italian. This coffee is much smaller than a regular latte, typically served in a small cup of about 3–4 ounces (approximately 90–120 ml), with a coffee-to-milk ratio of roughly 1:2, topped with light milk foam. Its hallmark is a more concentrated espresso flavor, with the milk complementing rather than overpowering it—making it perfect for those who enjoy pure coffee flavors.

So, how can you make a Flat White at home? Taking the common professional café recipe as an example, it’s recommended to use a double ristretto as the base, with extraction parameters set to 20 grams of coffee grounds yielding 35 grams of coffee liquid, extracted in about 26 seconds. This extraction preserves the essence of the espresso’s middle-to-front section, resulting in a brighter and more layered flavor.It’s important to note that each coffee bean has slightly different extraction characteristics, so it’s recommended to fine-tune grind size and water temperature based on the actual bean profile.

For the milk, it’s advised to heat it to 55–65°C. This temperature range balances the fineness of the milk foam and the aroma of the milk, avoiding overheating that could lead to nutrient loss and a rough texture. The milk foam should be controlled to about 1 cm thick, with a milk-to-coffee liquid ratio of roughly 1:5, and it’s recommended to use a 200 ml cup. Slowly pour the frothed milk into the coffee liquid, maintaining a steady flow rate and angle, and you’ll enjoy a Flat White where the coffee’s natural flavors shine through with smooth, velvety foam.

As for the Piccolo Latte, a common preparation method is to use a single espresso, with recommended parameters of 12 grams of coffee grounds yielding 30 grams of coffee liquid, extracted in about 23 seconds. Using a 100 ml cup, first pour about 60 ml of milk (frothed to about 0.5 cm thick) mixed with the coffee liquid, then top with light milk foam—or add latte art according to preference. Due to its smaller serving size, the flavor of the espresso is more pronounced in the Piccolo Latte, making it ideal for those who enjoy strong coffee flavors without needing a large portion.

In summary, whether it’s a Flat White, Piccolo, or Latte, selecting the right coffee beans and controlling the details of extraction and milk frothing are key to making a delicious milk coffee. By understanding their historical backgrounds, milk foam thickness, coffee proportions, and suitable flavor profiles, you’ll be able to more confidently choose or brew the espresso-based milk drink that suits your taste.
