Introduction:Latte, cappuccino, and flat white are the most common espresso-based milk coffees found in cafés. Although all three are made with espresso and milk, they differ in flavor profile, recipe proportions, and milk foam details. This article delves into the historical origins, brewing methods, and milk-to-foam ratios of these three classic milk coffees to help you understand their key differences and enhance your ability to discern flavors in coffee.

Although all are blends of espresso and milk, latte (Caffè Latte), cappuccino (Cappuccino), and flat white (Flat White) each occupy a unique spot on café menus and are not interchangeable. What exactly are the specific differences between these three classic espresso-based milk coffees in terms of espresso extraction parameters, fresh milk usage, and milk foam layers? Let’s start with their historical backgrounds, gradually break down their preparation logic, and through practical preparation data comparisons, clearly distinguish the essential differences between these three milk coffees.

In the world of coffee, just two basic elements—coffee and milk—can produce a variety of distinctly styled drinks. For those unfamiliar with coffee, these similarly named options can often be confusing. For example, Americano and Long Black are easily mistaken at a glance (those interested can look up more information). Among milk coffees, which are the main sales drivers in most cafés, the variety is even greater. Among them, the three most popular espresso-based milk coffees—latte, cappuccino, and flat white—all use espresso and milk as their base. Their procedures may seem similar, but in professional menus, they are never grouped together because there are clear distinctions in recipe and taste.

【Latte】Milk-forward, suitable for those who prefer a milder, sweeter taste

The latte is one of the most well-known espresso-based milk coffees. Thanks to its simple preparation method and mild flavor, it is beloved by coffee beginners and everyday drinkers.

Although the origin of the latte lacks clear documentation, it is certain that even before the advent of espresso, people in Europe were already drinking coffee with milk. However, the brewing techniques at the time were more primitive—typically boiling a whole pot of coffee and filtering out the grounds, or using early versions of the moka pot for extraction. It wasn’t until the popularization of espresso machines, equipped with steam wands capable of stably heating and frothing milk, that the modern latte began to take shape, later propelled globally with the rise of latte art culture.

【Cappuccino】Thick milk foam, with origins tied to monk attire

The name cappuccino originates from Italy but actually evolved from the German word “Kapuziner,” meaning “monk.” Research suggests this drink was born in 18th-century Vienna, where coffee was still consumed with the grounds. A Pole improved the taste by using a cloth bag to filter out coffee grounds and adding honey, spices, and cream, resulting in a beverage color similar to the brown robes of Capuchin monks—hence the name “Kapuziner.”

Later, this drink spread to Italy. With the development of espresso machines, Italians switched to using espresso as the base, replacing cream with densely frothed milk, and shaping the foam into a monk-hood-like form with a spoon, gradually evolving into today’s cappuccino.

【Flat White】Highlights the coffee’s inherent flavor, originating from Australia and New Zealand

Compared to the first two, the flat white has a shorter history, emerging around the mid-to-late 20th century. When espresso culture arrived in Australia and New Zealand, local consumers were less receptive to traditional cappuccinos and lattes. So baristas began adjusting the ratio of milk to coffee in hopes of better appreciating the coffee’s own flavors.

To reduce the interference of milk foam, they frothed the milk thinner, allowing the coffee and milk to blend more uniformly, eventually creating a milk coffee with an extremely thin, flat layer of foam—Flat White, literally meaning “flat white milk coffee.” Since the 1980s, this beverage has gradually gained popularity in Australia and spread worldwide.

1. Espresso Extraction Volume: Flat White demands more, Latte and Cappuccino are similar

In terms of espresso extraction, lattes and cappuccinos usually use a standard double shot (about 30–40 grams of coffee liquid), with relatively loose requirements for extraction parameters—the focus is more on milk handling and proportioning.

The flat white, however, emphasizes the layered aroma and flavor of the coffee, so it typically uses a double ristretto shot from the heart and middle sections of the coffee puck, extracted with 20 grams of coffee grounds to yield 30 grams of coffee liquid, with time controlled within 22 to 25 seconds, ensuring richness and concentrated flavor, making the coffee's inherent characteristics more prominent.

2. Milk Proportion: Latte has the most, Cappuccino the least, Flat White in between

“Latte” means “milk” in Italian, so lattes have the highest milk ratio, usually making up most of the drink—offering a noticeable sweetness and soft flavor. For instance, based on a double shot (around 40 grams of coffee liquid), it pairs with 240 milliliters of fresh milk, suitable for drinkers who enjoy a balanced taste of milk and coffee, and can also be customized with syrups or spices as preferred.

The cappuccino is a classic combination of equal parts coffee, milk, and foam, but in practice, to avoid too much foam affecting taste, it is usually prepared in a 200-milliliter cup, with about 40 grams of double shot espresso, then added with 140–150 grams of frothed fresh milk, with a milk foam layer about 1.5 centimeters thick, resulting in a more harmonious overall proportion.

The flat white emphasizes the main body of the coffee, with milk playing a supporting role. The milk amount is less than in a latte, usually using a 200-milliliter cup, with 160 milliliters of fresh milk, resulting in a cleaner, more refreshing taste, while allowing the coffee’s own aroma and sweet-acid layers to come through clearly.

3. Milk Foam Thickness: Cappuccino the thickest, Latte moderate, Flat White the thinnest

The cappuccino’s hallmark is its prominent “hat” of foam, usually more than 1.5 centimeters thick, so frothing requires significant aeration to create a dense texture. This thick foam isn’t ideal for intricate latte art; simple designs suffice.

Lattes, due to their higher milk proportion, are usually served in wide cups, with foam thickness controlled at 0.5–1 centimeter, helping the coffee and milk blend evenly while leaving enough room for creative latte art.

Flat whites pursue an ultra-smooth, silky mouthfeel, with only an extremely thin layer of foam—about 0.3 centimeters thick. The temperature is advised to be controlled at 50–55°C, allowing drinkers to best enjoy the harmony of coffee and milk.
