What makes a good cappuccino?
A cappuccino is an espresso drink with steamed milk and milk foam. A good cappuccino balances the taste of espresso, the natural sweetness of milk, and a pleasant foam texture. The well-known division of one-third espresso, one-third steamed milk, and one-third foam is a useful explanation, but not a strict formula for every cappuccino.
During more than ten years of barista workshops, I often see that home baristas mainly focus on the milk foam. However, the result already begins with the coffee beans, the roast, the freshness, and how the espresso is extracted. After that, the milk's temperature, the amount of air, and the ratio in the cup determine how the cappuccino ultimately tastes. In this blog, I explain where the drink comes from, which components work together, and what you can practically pay attention to at home or in a café.
From monkshood to coffee drink
The name cappuccino is older than the modern espresso drink. Its history runs from Viennese coffee culture to the Italian espresso bar.
Where does the name cappuccino come from?
Three parts, one whole
The classic three-part division helps to explain cappuccino. In the cup, it's all about the function and balance of each component.
What does a cappuccino consist of and what is the correct ratio?
Espresso forms the flavour base, providing aroma, body, sweetness, and pleasant bitterness. Warm milk softens and enriches this concentrated coffee. Milk foam adds texture and largely determines how creamy or airy the drink feels. The well-known ratio of one-third espresso, one-third warm milk, and one-third foam is therefore primarily a practical starting point. With modern microfoam, milk and foam are no longer seen as separate layers; together they form a fine, glossy structure. Therefore, also consider the size of the cup and taste whether the espresso remains discernible. A cappuccino that only tastes of warm milk lacks coffee strength. A dry foam cap with large bubbles, on the other hand, offers little creaminess.
Coffee that remains recognizable in milk
Milk dampens some of the coffee flavor. Coffee beans for cappuccino should therefore retain sufficient body and flavor intensity.
Which coffee beans are suitable for cappuccino?
For many cappuccino drinkers, a medium to medium-dark roast is a logical starting point. Flavour profiles with chocolate, caramel, nuts, brown sugar, or dried fruit generally combine easily with milk. A light roast can remain fresh and fruity, but sometimes also come across as noticeably acidic. A very dark roast offers a lot of strength and can simultaneously taste smoky or bitter. An espresso blend is often composed for balance, body, and reliable extraction, although a suitable single origin can also work well. When purchasing, pay attention to the flavour profile, the recommended use, and especially the roast date. It's better to buy a quantity that you will use regularly, store the coffee beans sealed, dry and dark, and grind them just before you make the espresso.
Control begins before the milk
In addition to our unique expertise in the field of circular economy, we are also experienced in the field of recycling of various materials and components, for example within our own waste sorting installation. For example, we separate and recycle materials such as paper, cardboard, plastics, metals and textiles.
Why does a good cappuccino start with good espresso?
If water flows through the ground coffee too quickly, the espresso often tastes thin, sharp, or sour and easily disappears into the milk. If the extraction is too slow, heavy, bitter, and dry flavors can emerge. Therefore, use a consistent dosage, measure how much espresso enters the cup, and monitor the extraction time. A coffee scale and shot glass help to visualize changes. At home, this provides peace of mind when you open a new bag of coffee beans. In a restaurant setting, a consistent recipe helps different employees make the same cappuccino. Also, taste the espresso occasionally without milk. This way, you'll notice sooner if the grind, dosage, or freshness needs adjusting.
Add air and let the milk roll

How do you make good milk foam for cappuccino?
For traditional cappuccino foam, you add a relatively large amount of air, resulting in a thicker, more prominent layer of foam. For modern cappuccino and latte art, you add less air and distribute it more finely throughout the milk. Good microfoam is shiny, creamy, and free of large visible bubbles. At the beginning, keep the tip of the steam wand close to the surface of the milk, then allow the milk to circulate in the pitcher. This swirling motion creates a more even texture. Heat the milk in a controlled manner, as overheating reduces sweetness and texture. When practicing, always use the same milk, milk pitcher, and quantity. Clean the steam wand immediately. While a heart shape can indicate well-pourable milk, taste and mouthfeel remain more important than the pattern.
Frequently asked questions about making cappuccino
What is the classic ratio for a cappuccino?
One-third espresso, one-third hot milk, and one-third milk foam is the classic explanation. With microfoam, milk and foam merge, making the balance of flavour more important than three distinct layers.
Which coffee beans are best for cappuccino?
Why does my cappuccino taste mostly like milk?
How do I prevent large bubbles in my milk foam?
Briefly and gently incorporate air at the beginning, then let the milk spin well. Use cold milk and keep the steam wand clean.

How to make a better cappuccino, step by step
A good cappuccino is not created by one single trick. The coffee beans must be compatible with milk, the espresso must run through in a balanced way, and the milk needs a temperature and structure that remains sweet and creamy. Therefore, start with one fixed routine: use fresh coffee beans, measure your espresso, froth the same amount of milk, and taste what changes. If you get stuck on the ratio, extraction, or milk structure, De Barista Shop will help you choose the right path: a targeted online module, a practical tool, or a personal workshop. This is how De Barista Shop helps you make better coffee, both at home and in the workplace.
