Introduction:Have you ever wondered what the difference is between a flat white and a latte? After all, they’re both milk-based coffees, yet they taste quite different. From the coffee base and milk volume to the thickness of the milk foam, there are actually clear distinctions in the details. This article takes an in-depth look at the characteristics of these two classic coffee drinks to help you find the one that best suits your taste, and to clarify why flat whites are mostly only offered as hot drinks, as well as how to choose a rich yet not overly milky coffee based on your preferences.
Although both flat whites and lattes fall under the category of milk coffee, their flavor profiles and mouthfeel differ noticeably when it comes to actual drinking. Many customers who order a flat white at certain cafes will notice that its serving size is noticeably smaller than that of a latte, with a more concentrated coffee flavor and relatively thinner milk foam. In fact, the flat white evolved from the latte, but with some key adjustments made in the details.
The name “latte” comes from Italian, literally meaning “milk.” This drink combines espresso with a large amount of milk, allowing you to enjoy both the richness of the coffee and the silky sweetness of the milk. Generally speaking, lattes contain more milk, which creates a more balanced flavor profile with the coffee base, making them suitable for those who prefer a milder coffee taste.
As for the flat white, it is characterized by a more intense coffee expression. Legend has it that this drink originated last century when Italian coffee culture was introduced to Australia and New Zealand. Local consumers were not particularly fond of the thick milk foam style of cappuccinos or lattes, so a version with thinner foam and a more prominent coffee flavor gradually developed. When the milk is combined with an extremely thin layer of foam, the surface becomes smooth and level with the rim of the cup — this is also the origin of the word “Flat” in “Flat White.”

In terms of the coffee base, lattes typically use a standard espresso as the foundation, while flat whites prefer to use ristretto. Ristretto is a shot of espresso extracted with a shorter brew time and less water, resulting in a stronger flavor with rich sweetness and fruity acidity, which makes the coffee essence of the flat white stand out even more.
In terms of milk volume and overall serving size, lattes usually add more milk to maintain a balance between coffee and milk, resulting in a larger overall drink volume and a milder flavor. In contrast, flat whites intentionally reduce the amount of milk used, allowing the coffee flavor to be more full-bodied and concentrated, hence the serving size is naturally a bit smaller than that of a latte.
As for the thickness of the milk foam, this is one of the most直观 differences between the two. A typical latte has a milk foam layer of about 0.5 centimeters, which, when combined with the coffee liquid and styled with latte art, can present a slightly raised, plump visual effect. The milk foam of a flat white, on the other hand, is noticeably thinner and must be strictly controlled to bewithin 0.3 centimetersto ensure that the final liquid surface remains level with the rim of the cup, truly showcasing the “Flat” characteristic. If the foam is too thick, not only will it fail to create a flat surface, but it will also affect the overall balance of flavors.
It’s worth noting that traditional flat whites are usually only offered in hot form. This is because hot drinks can fully showcase the aroma and richness of the coffee, whereas switching to iced versions not only dilutes the coffee concentration but also makes it difficult to present the delicate texture unique to flat whites. If you’re after a strong coffee flavor but don’t want to consume too much milk, you might consider trying the “Dirty” drink, which also highlights the charm of espresso but in a more direct way.
Overall, the flat white features delicate and light milk foam, a distinct and layered coffee flavor, and a smooth mouthfeel; whereas the latte has slightly thicker milk foam, with an overall more gentle, creamy, and balanced presentation, making it suitable for those who enjoy a balanced combination of milk and coffee. Although the two may seem similar, every aspect — from the choice of base, milk volume control, to the milk foam technique — influences the final drinking quality and flavor expression. Different shops may also make slight adjustments to these two coffees based on their own styles, so when trying them out, it’s recommended to sample offerings from different cafes to find the one that best suits your taste.
