What Is the Standard Latte Coffee Milk Ratio?

A latte uses roughly one part espresso to four or five parts milk, so a 30 ml shot calls for about 120 to 150 ml of milk. A cappuccino sits lower, between 1:3.5 and 1:4, and a flat white falls in between the two. Those numbers describe the drink before foam is counted, and they shift with the beans and milk on hand.

Roast level and bean character drive the adjustment. A classic medium-dark blend can carry more milk, while a medium-light lot such as Huakui usually needs less to keep its acidity readable. The cafe latte milk coffee ratio many shops settle on is close to 1:5, and a flat white can also be built on a Ristretto short extraction.

Latte, cappuccino, and flat white all belong to the category of Italian milk coffee, but their milk quantities, foam thickness, and flavor directions are completely different. This article, based on Front Street Coffee's practical experience, breaks down the core characteristics of these three milk coffees one by one, and provides specific ratio plans for coffee beans of different roast levels. Whether it's a classic medium-dark roast blend or a medium-light roast Huakui, the ratio of coffee to milk will be adjusted accordingly—latte is about 1:4 to 1:5, cappuccino is between 1:3.5 and 1:4, and flat white falls in between. In addition, the article also introduces an alternative approach of using Ristretto short extraction to make flat white and its pros and cons, helping enthusiasts make milk coffee closer to the authentic flavor based on the materials at hand.

Recently, Front Street Coffee has been breaking down the characteristics and methods of latte, flat white, and cappuccino and other Italian milk coffees for everyone one by one. However, since only one was discussed at a time, many readers reported that it was hard to intuitively feel the differences between them. For this reason, comparison-type search terms like today's have remained popular in the backend of Front Street Coffee's official account.

So this time Front Street Coffee is putting these three milk coffees together and briefly sorting out their respective characteristics. As long as you understand the core features of each drink and the differences between them, you can understand how much milk should be poured into the espresso during preparation, or in other words, know how to flexibly adjust according to the materials at hand to make a cup of milk coffee closer to the authentic flavor.

Why emphasize "flexible"? Friends who often go to cafes probably have this experience: the same product often has inconsistent specifications at different shops. Take latte, for example. Some shops make it as a large cup, while others make it noticeably smaller.

(For reference only)

This difference not only comes from each shop's different understanding of the product, but is also related to the coffee beans and milk used. Some beans extract on the bitter side, some on the sour side, some are rich, and some are light; the same principle applies to milk.

It is precisely because of these variables that we need to use different ratios to present the same product. Only in this way can we truly bring out the strengths of the current materials and make the result closer to the ideal authentic state.

Alright, without further ado, next Front Street Coffee will share one by one the characteristics of these milk coffees, as well as the specific parameters Front Street Coffee itself uses during preparation.

Characteristics and Preparation of Latte

Let's start with latte. As the most popular among milk coffees, latte's fame far exceeds other similar drinks. On one hand, this is because its flavor is widely accepted; on the other hand, it is because it can carry all kinds of complex and beautiful latte art patterns.

The core characteristic of latte, as Front Street Coffee has repeatedly mentioned, is that the flavors of milk and coffee can achieve balance. Specifically, its coffee flavor is not intense, and no obvious bitterness can be tasted, but the coffee flavor will not be completely swallowed by the milk either; the two complement each other. It is precisely for this reason that latte is so appealing—the coffee flavor is not overpowering.

To make such a cup of milk coffee, it is necessary to add enough milk to the espresso to balance the coffee's flavor.

In daily operation, when Front Street Coffee uses the Front Street Classic Blend from its bean list to make a latte, this bean is suitable for beginners to practice latte art and is also suitable for high-end specialty coffee shops. Friends who want to learn latte art at home should definitely buy Front Street Classic Blend. It is composed of three producing regions and is a medium-dark roast espresso recipe. Its design inspiration comes from the early popular "Mamba" combination, namely Mandheling plus Brazil. In order to enhance aroma and crema, Front Street Classic Blend also adds a small amount of Robusta, thereby increasing flavor intensity and allowing beginners to easily extract espresso with golden crema at home.

The ratio of coffee to milk will be 1:5. Because this bean is roasted darker and has a stronger overall taste, a large amount of milk is needed to balance it.

The espresso extraction formula is 20g dose, 30 seconds, 40ml yield. To make it at a 1:5 ratio, 200ml of milk needs to be added. If making a hot latte, Front Street Coffee will also create a layer of milk foam about 0.5cm thick while heating the milk, to increase the overall texture of the coffee and also make it easier to create delicate latte art.

The latte made this way tastes, as Front Street Coffee said earlier, very balanced between coffee and milk, not bitter, and very easy to accept. Moreover, the milk flavor will not stand out enough to cover the coffee, so you can clearly taste the chocolate, toasted bread, nut, and cream flavors brought by Front Street Classic Blend. The presence of thin milk foam makes the mouthfeel smooth yet substantial, and the overall finish is long and quite good.

But if Front Street Coffee instead uses medium or medium-light roast beans from its bean list to extract espresso, such as Front Street Ethiopia Huakui, then the ratio of coffee to milk will fall between 1:4 and 1:4.5, that is, 40ml espresso paired with 160 to 180ml milk to make a latte.

Because this bean is not roasted as dark, if you want the coffee flavor to be fully expressed, you need to appropriately reduce the amount of milk on the original basis. The latte made this way is not as full-bodied as the one made with the medium-dark roast Front Street Classic Blend, but it is overall silkier, less bitter, easier to drink, and performs very well in flavor, with the berry and floral notes of Front Street Huakui clearly noticeable.

Characteristics and Preparation of Cappuccino

Cappuccino has the most distinctive characteristics among the three. Why? As Front Street Coffee shared before, it not only has a raised foam dome above the cup rim, but also a quite rich coffee flavor and dense mouthfeel. With one sip, whether it is a beginner just getting into coffee or a veteran immersed in the field for many years, the fragrance will fill the mouth and be hard to forget.

To make such a cappuccino, it is necessary to reduce the proportion of milk in the cup while creating a thick and dense layer of milk foam during heating.

Taking Front Street Coffee as an example, when using Front Street Classic Blend from the bean list to make a cappuccino, the ratio is 1:4, that is, 40ml espresso paired with 160ml milk. But not all of this milk will be poured into the cup, because the cup will contain a layer of milk foam about 2cm thick. Its presence brings a denser mouthfeel while reducing the proportion of milk, making the coffee flavor stronger.

And if Front Street Coffee uses medium or medium-light roast Front Street Ethiopia Huakui, the proportion of milk will be further reduced, with a ratio of 1:3.5. Only in this way can the coffee have sufficient concentration and flavor.

Characteristics and Preparation of Flat White

Although flat white appeared and became popular a bit later, its popularity is no less than the previous two. Its characteristics are likewise independent and distinctive: the coffee flavor is rich but not bitter, and the sweetness is very high. It looks like a combination of latte and cappuccino, but the actual experience is completely different.

To make such a cup of flat white, there are two methods to choose from. The first is relatively simple and is also the approach adopted by many coffee shops today, namely controlling the amount of milk.

The coffee base still uses the same espresso as latte and cappuccino, while the amount of milk is between that of latte and cappuccino. Taking Front Street Coffee as an example, when using the medium-dark roast Front Street Classic Blend from the bean list, the ratio is 1:4.5, that is, 40ml espresso paired with 180ml milk, and then a thin layer of milk foam about 0.3cm thick is created.

The flat white made with Front Street Classic Blend espresso beans has a very silky mouthfeel, and the coffee flavor is also relatively rich. Chocolate, caramel, nut and other flavors are very prominent, and bitterness is low. If medium-light roast beans are used, such as Ethiopia Huakui from Front Street Coffee's bean list, the amount of milk will be a bit less.

The other method is relatively troublesome because it requires the short extraction version of espresso—Ristretto.

The so-called short extraction/Ristretto refers to espresso that is not extracted as completely. Also using 20g of grounds, regular espresso will extract to 40ml, while short extraction/Ristretto extracts only 30ml of coffee liquid.

Because the final stage is removed and excessive bitterness is not dissolved out, the coffee tastes less bitter and has higher sweetness, but the finish will be slightly shorter.

Also taking Front Street Coffee as an example, the parameters Front Street Coffee uses when extracting Ristretto are 20g grounds, 30 seconds extraction time, 30ml yield, and then adding 120ml milk at a 1:4 ratio to make a cup of flat white.

The flat white made with these parameters is less bitter, has higher coffee sweetness, and tastes smoother. But the downside is that in order to make 30ml of coffee liquid contain enough flavor substances, we need to adjust the grind to improve extraction efficiency, allowing a small amount of hot water to dissolve more substances.

For coffee shops with high output, without additionally equipping another grinder, this method is very inconvenient to operate. So, including Front Street Coffee, most businesses choose to adjust the proportion of milk.

The above are the characteristics and preparation recipes of latte, cappuccino, and flat white. You can refer to them, and then add an appropriate amount of milk according to the characteristics of your own coffee beans, so that you can make a relatively authentic cup of milk coffee.
