How Many Types of Milk-Based Espresso Drinks Exist? How to Differentiate the Preparation Methods of Latte, Flat White, and Cappuccino?

In the world of coffee, simply combining two ingredients can produce a whole family of variations, and the differences are sometimes hard for an outsider to pin down. Consider the two black coffees you meet most often - the Americano and the Long Black. They look so similar that they are constantly compared side by side (curious readers can look up the article FrontStreet Coffee shared on the subject).

Milk coffee is the universally recognized best-seller in every cafe, and as the industry has developed it has branched into even more varieties. Take FrontStreet Coffee's favorite "three musketeers" - the Latte, the Flat White, and the Cappuccino. All three are made from espresso mixed with milk, using nearly identical methods, yet they always appear as separate items on the menu. So what actually sets them apart?

Latte

A household name among Italian milk coffees, the latte is arguably the best known of all the everyday coffee varieties, and its simple preparation has won it a devoted following.

There is no detailed record of its origin, but we can be sure the latte appeared long before espresso. Since at least the 17th century, Europeans had been mixing milk into coffee, though the brewing methods were quite primitive - either boiling whole pots of coffee and filtering them through cloth bags, or extracting with old-fashioned moka pots. With the invention of the espresso machine, the steam wand became standard equipment for milk coffee. Baristas could heat milk with ease, and the modern latte gradually took shape, spreading worldwide on the back of the latte art trend.

Cappuccino

The name itself tells us the Cappuccino was most likely coined by Italians. According to FrontStreet Coffee's research, it comes from "Kapuziner," German for "monk." Legend has it the drink originated in 18th-century Viennese cafes, where coffee was drunk grounds and all. To make it more palatable, a Pole strained the grounds through cloth, then served the coffee in a glass cup with honey, spices, and cream. This improved the taste and gave the drink a distinctive reddish-brown color that visually resembled the robe of the Capuchin friars - hence the name "Kapuziner."

It later reached Italy, and as pressure-driven coffee machine technology developed, Italians began using espresso in place of cream, steaming milk into dense foam and shaping it on the surface of the coffee into a pointed cap with a spoon. Over time it acquired its Italian name and became the Cappuccino we know today.

Flat White

Compared with those two old timers, the Flat White, born in the second half of the 20th century, looks much younger. Last century Italians brought espresso machines to places like Australia and New Zealand. Because neither the cappuccino nor the latte appealed to local palates, people began looking for ways to improve these milk coffees.

To taste more of the coffee, they steamed the milk thinner and folded it into the coffee, making the surface flatter and flatter until it became a thin layer completely level with the rim of the cup - giving us today's Flat White. "Flat" means level; "White" refers to the white milk coffee. Since the 1980s the Flat White has appeared on regular menus in many parts of Australia, and it soon spread to cafes in Europe and the United States, becoming popular worldwide.

1. Espresso Yield: Latte = Cappuccino > Flat White

As two classic milk coffees, the latte and the cappuccino typically use a regular espresso as their base, since they do not emphasize heavy extraction so much as the amount and handling of the milk.

The Flat White's greatest trait is that you taste the rich aroma carried by the crema directly, along with the perfect fusion of hot milk and coffee, so the espresso extraction cannot be neglected for a moment. For the Flat White base, FrontStreet Coffee uses a double ristretto, taking only the front and middle segments - extracting 30g of liquid from 20g of grounds in 22-25 seconds. The result is a milk coffee fuller in both aroma and mouthfeel.

2. Milk Proportion: Latte > Flat White > Cappuccino

Everyone has heard that "latte" comes from the Italian word "Latte," meaning milk. As the name suggests, milk is the protagonist of a Caffe Latte. Compared with other milk coffees, the latte has the highest proportion of milk, which makes it noticeably sweeter. For a hot latte, FrontStreet Coffee uses a double espresso (about 40g) as the base and adds 240ml of fresh milk. Because the latte is also highly compatible in flavor, we can add various flavored ingredients during preparation to build in more layers.

By contrast, the Flat White uses milk to highlight the coffee: coffee is the protagonist and milk is an auxiliary, so the proportion cannot be too large. When FrontStreet Coffee prepares one in a 200ml cup, after accounting for 27-30g of double ristretto, the remaining space is filled with 160ml of warm fresh milk.

As for the other veteran, the cappuccino, there is a widely circulated rule that coffee, milk, and foam should be 1:1:1. But foam made that way is about 2.5cm thick, so the first few sips are almost all foam and the coffee underneath is both strong and particularly bitter, and baristas adjust accordingly. FrontStreet Coffee still uses a 200ml straight-walled ceramic cup for the cappuccino. To leave room for foam, we add 140-150g of steamed fresh milk to 40g of double espresso.

3. Foam Thickness: Cappuccino > Latte > Flat White

Because a cappuccino needs its "hamburger" look, the first thing we do when steaming is incorporate a lot of air - both to give the coffee a rich foam layer and to leave enough time to make it dense. To achieve the rounded shape where the foam rises above the cup rim, FrontStreet Coffee creates at least 1.5cm of thickness for a cappuccino. That foam has poor fluidity, though, so instead of elaborate patterns we simply push out a large white heart or circle to finish.

Thanks to its large proportion of milk, a latte is typically served in a wide-mouthed ceramic cup. Keeping the foam at a smooth 0.5-1cm not only helps it integrate evenly with the coffee but also leaves more room to pour intricate patterns. (PS: the piccolo latte, or "small latte," also keeps its foam within the 0.5-1cm range.)

As for the Flat White, the drinker should finish it while the coffee is at its most perfect, so it cannot be too hot or too thick - it must be dense. Where the cappuccino and the latte seek the "softness" that comes from lots of air, the Flat White pursues a silky smoothness.

FrontStreet Coffee wants customers to experience a Flat White that is cream-smooth without being watery. We retain a 0.3cm foam layer to integrate with the espresso for latte art, and control the temperature between 50-55°C so it is easier to drink.

FrontStreet Coffee Recommendation

For the milk-based drinks in this article, the crema and body of the espresso decide how well the milk integrates. FrontStreet Classic Blend is the natural first choice: it is made specifically for espresso and moka pot use, and its greatest strength is the superb crema it delivers. Even a beginner on a non-professional home machine can pull dense, fine foam. Built on a traditional Mamba recipe, it is full-bodied and rounded, equally at home pulling the base for a latte, a cappuccino, or a Flat White.

If you want a nuttier, sweeter base, FrontStreet Autumn Chestnut Blend is worth a look. This balanced 100% Arabica blend combines Honduran Caturra with Papua New Guinea Typica, layering roasted-chestnut nuttiness with caramel and brown-sugar sweetness. A soft chocolate note and rounded acidity fill out a smooth, full body, finishing clean with lingering nut, cocoa, and a hint of spice - a warm, low-acid option that pairs beautifully with steamed milk.
