The Correct Way to Make Cappuccino: Coffee to Milk Foam Ratio and How to Drink Cappuccino

The Evolving Classic: Understanding Cappuccino Through the Ages

Cappuccino is a milk coffee that has appeared on countless cafe menus. As coffee culture and trends have developed around the world, the definition of cappuccino has kept shifting, and the look of this classic drink has changed in very visible ways.

The Origins of Early Cappuccino

Exactly who invented the cappuccino is hard to pin down today, but research shows that the word "Cappuccino" comes from "Kapuziner," which means "monk" in German and also referred to an old-style coffee.

Legend places the drink's origin in 18th-century Viennese coffee houses. At the time, coffee was drunk together with the grounds. To make it more palatable, a Polish man named Kulczycki filtered the grounds out with a cloth bag, then served the coffee in a glass, adding honey, spices, and cream. That not only improved the taste but also produced a special reddish-brown color that visually echoed the robes of the Capuchin friars, so the Viennese called it "Kapuziner."

As the drink spread to Italy and pressure-driven espresso machine technology developed, Italians began using espresso instead, replacing cream with milk frothed into a dense foam, then using a spoon to shape the foam on the surface of the coffee into a peaked hat. Gradually it took on its Italian name, and that is the cappuccino we know today. Some theories, meanwhile, trace it to the word "Capuchin," referring to the religious garment. As for its predecessor "Kapuziner," people prefer to call that Viennese coffee.

The Appearance of Traditional Cappuccino

On preparation, the most widely accepted formula holds that the ratio of coffee, milk, and foam should be 1:1:1. Taking a 6-ounce (approximately 177 ml) cup as an example, that means a double espresso (60 ml), 1/3 hot milk (60 ml), and the remaining 1/3 foam. The foam built this way is about 2.5 cm thick, so the first few sips are almost entirely foam while the coffee at the bottom stays very intense.

In the era before steam wands appeared, milk foam could only be made by hand, and the result was relatively coarse. When making cappuccino back then, the thick, shaped foam was first scooped into the cup with a spoon until it was filled to 11/10ths, and the foam breaking free from the spoon formed a small white peaked hat. The foam at that time had a meringue-like consistency, very stable, but it did not integrate well with the coffee.

The "Golden Circle" of Cappuccino

With the arrival of more powerful Italian espresso machines came the method of frothing milk with steam. Steam wands not only create dense, rich foam and greatly improve service efficiency, they also eliminate the step of scraping foam with a spoon. That is why later cappuccinos no longer carried the "small peaked hat," replaced instead by a smooth, raised rounded dome.

From then on, a small cup size, raised foam, intense coffee flavor, and the thick, dense sensation of heavy foam became the traits everyone associates with cappuccino. Yet precisely because this thick foam layer reduced the fluidity of the steamed milk, making it hard to create the elaborate latte art patterns seen in lattes, some baristas adopted a central pouring method, letting the foam fall gently into the espresso and thereby forming the iconic "golden circle."

Latte Art: Making Cappuccino Foam Thinner

Today, with latte art so prevalent, baristas cannot wait to create beautiful flower patterns on every milk coffee, and cappuccino is no exception. To achieve simple decorative patterns, baristas consciously introduce less air when frothing, making the foam thinner to improve its fluidity. And because an overfilled cup easily spills, some coffee shops offering takeout deliberately reduce the dome effect, doing away with the shape that stands up to 11/10ths.

Of course, FrontStreet Coffee believes the so-called classic cappuccino does not mean restoring ancient recipes without question. In fact, with changes in bean quality, roast level, extraction equipment, and public taste, cappuccino has continually evolved along with the times. But if those changes drift away from the traits of "small cup size, filled to 11/10ths, intense coffee flavor, and the full, dense texture brought by thick foam," then what you have may no longer be a cappuccino.

FrontStreet Coffee Recommendation

A cappuccino lives or dies on the quality of its espresso, and FrontStreet Coffee builds its milk-coffee lineup around exactly that. For the base shot, FrontStreet extracts 20 g of grounds at a 1:2 ratio over 30 seconds, yielding an espresso that is concentrated enough yet fully extracted and solid in both flavor and body. For beginners, the Classic Blend is the "crema bomb" and the Black Cacao base blend is the value pick; both were designed for espresso machines and moka pots, and they shine when paired with the thick, fluffy foam that defines a cappuccino.

If you want to push a cappuccino toward fruit and flower, the Strawberry Candy espresso blend is the first choice, delivering berry, rose, raisin, and fruit-candy aromas. For a fresher, less bitter cup, the Granada Geisha SOE is naturally processed and medium roasted, so the bean itself brings berry, orange, and persimmon, and takes on a candy-sweet character once milk is added.
