A Tale of Two Milks
Though they share the same ingredients of espresso, milk, and foam, a cappuccino and a latte are distinguished by their ratios and, most importantly, the texture of the milk. A traditional cappuccino is a study in thirds: one-third espresso, one-third steamed
milk, and one-third dense, airy foam. This creates a smaller, more coffee-forward drink, typically served in a 150-180ml cup. In contrast, a latte is much more milk-heavy, with a ratio closer to one part espresso to three or four parts steamed milk, all topped with just a thin layer of foam. This results in a larger, creamier, and milder beverage.
The Science of 'Dry' vs. 'Wet'
The term "drier" in the context of a cappuccino refers to the sensation created by its foam. Baristas create this by introducing more air into the milk for a longer period during steaming. This process produces a light, stiff, and airy foam—often called 'dry foam' or macrofoam—that sits distinctly on top of the liquid coffee. This separation of layers is what gives the cappuccino its characteristic textural contrast: you first encounter the light foam, then the more intense coffee underneath. A latte, on the other hand, is considered a 'wet' drink. Its milk is aerated for a much shorter time, creating a silky 'microfoam' that integrates smoothly and completely with the steamed milk and espresso, resulting in a uniform, creamy texture from the first sip to the last.
How Foam Transforms Flavour
The texture of the milk doesn't just affect mouthfeel; it fundamentally changes the taste of the drink. The thick foam cap on a cappuccino acts as an insulator, keeping the drink warmer for longer. It also means the espresso flavour beneath is less diluted by milk, leading to a stronger, more pronounced coffee taste. When you sip a cappuccino, the bold espresso flavour comes through the light foam with intensity. The greater volume of steamed milk in a latte does the opposite. Heating milk enhances its natural sweetness by breaking down lactose sugars. In a latte, this sweetness is blended throughout the drink, mellowing the bitterness and acidity of the espresso to create a smoother, more balanced flavour profile.
Ordering with Confidence
Understanding this distinction can help you tailor your coffee order. If you enjoy a robust coffee flavour and a light, multi-layered texture, a traditional or 'dry' cappuccino is your ideal choice. These are all about the distinct layers of airy foam and strong espresso. If you prefer a milder, creamier, and sweeter coffee experience where the espresso is softened by the milk, a latte is the way to go. Some cafes even offer variations like a 'wet' cappuccino, which has more steamed milk and less foam than a traditional one, bridging the gap between the two drinks.
