Latte vs Cappuccino: How Much Milk Foam Is Right?

Ever ordered a latte and wondered why it tastes so milky compared to your friend’s cappuccino? Or received a cappuccino that barely had any foam and felt more like a latte? The difference comes down to just two things: how much milk you use, and how thick the foam is. But those small adjustments create dramatically different drinks.

To put it simply: a traditional cappuccino uses about 1cm of thick, dry foam on top, while a latte has just a thin layer—around 0.5cm or less—of velvety microfoam. That small change swaps texture, mouthfeel, and even coffee flavor balance.

What Actually Defines a Cappuccino vs a Latte?

Both drinks start the same: a shot of espresso, steamed milk, and foam. But the key difference is the amount and texture of the foam. A cappuccino is built with a thicker, drier foam layer—about 1cm tall—sitting on top of a smaller portion of steamed milk. A latte, by contrast, has a much thinner layer of microfoam—less than 0.5cm—and far more steamed milk beneath. In fact, when a cappuccino’s foam drops to around 1cm or less, many consider it functionally a latte.

Why Does Foam Thickness Change the Drink So Much?

Foam isn’t just fluff—it affects how the drink looks, feels, and tastes. Here’s how:

• Visuals & Pouring: Thick foam (like in a classic cappuccino) makes latte art difficult. You can’t pour delicate designs like tulips or leaves cleanly—it often turns into a “fishbone” effect. That’s why competitive baristas rarely pour complex patterns into cappuccinos anymore. Most opt for symmetrical tulips instead.
• Texture: Imagine a spectrum: on one end, you have the big, bubbly foam from low-quality chain cappuccinos; on the other, pure hot milk. The more foam (especially dry, airy foam), the rougher and more “grainy” the mouthfeel. Microfoam, used in lattes, is smoother and silkier. Too much foam can feel unpleasant—just like overly tannic espresso or tart wine—but balance is key.
• Flavor Balance: More foam means more air and less liquid milk, so the coffee flavor stands out more. Less foam means more milk, making the drink creamier and sweeter. That’s why some people say “if you want coffee flavor, don’t order a latte”—but that’s not entirely accurate. Lattes do have more milk taste, but they still carry plenty of espresso character. In fact, World Barista Championship baristas tweak their cappuccino milk ratios and espresso roast levels specifically to balance this out.

How Do Different Versions Compare in Practice?

Let’s assume a standard 200ml cup for easier comparison. In Australia, latte and cappuccino cups are often similar in size, just styled differently. Here’s how the same size changes the experience:

• Cappuccino (Traditional): About 1cm of thick foam, less steamed milk. More intense coffee flavor, drier mouthfeel, harder to pour art.
• Wet Cappuccino: Thinner foam (around 0.5–1cm), more steamed milk. Closer to a latte but still with some foam texture.
• Latte: Very thin microfoam (under 0.5cm), highest proportion of steamed milk. Silky texture, creamier taste, easier to pour latte art like tulips.

In the US, cappuccinos are often served in smaller cups than lattes. In Australia, both drinks may come in similar glassware, making the foam and milk ratios the main difference. The American-style cappuccino with big bubbles is generally considered the least desirable—both for texture and appearance.

What Do Professional Baristas Adjust For Taste?

Professional competitors and roasters think deeply about foam. For example, David Makin, an Australian WBC competitor, was coached by James Hoffmann to use more foam in his cappuccino when his espresso blend lacked body. With a less rich espresso, reducing milk volume and increasing foam helped the coffee shine through—even in a 160ml tulip cup with just 25ml espresso. That’s how critical foam thickness is to balance.

How to Make Each Drink at Home (Based on FrontStreet Methods)

While this article doesn’t provide a full home recipe, here’s what matters based on professional standards:

• For a cappuccino, aim for about 1cm of thick, dry foam. That’s achieved by aerating milk less and creating a firm foam layer.
• For a latte, go for ultra-fine microfoam, under 0.5cm, and use more steamed milk. This gives the silky texture lattes are known for.
• The espresso base should be around 20–25ml, extracted with a proper brew ratio (e.g., 1:2 in 30 seconds), to ensure enough strength to balance the milk.

FrontStreet Coffee’s guide to cappuccinos recommends using a thick, pillowy foam—achieved by extending aeration time and avoiding over-stretching the milk. They also note that different espresso blends (like their Strawberry Candy or Grana Geisha SOE) can dramatically shift how the milk and foam interact.

Frequently Asked Questions

How much milk foam should be on a cappuccino?

A traditional cappuccino has about 1cm of thick, dry foam on top. This is the key feature that separates it from a latte, which typically has under 0.5cm of microfoam. The foam in a cappuccino is firmer and creates a drier, more textured drink.

What’s the difference between a latte and a cappuccino?

The main differences are milk quantity and foam texture. A latte has more steamed milk and a thin layer of microfoam (under 0.5cm), resulting in a creamy, smooth drink. A cappuccino has less milk, more foam (around 1cm of thick foam), and a stronger coffee flavor with a drier mouthfeel.

Why is my cappuccino foam too bubbly or flat?

Foam quality depends on aeration and milk temperature. Big, loose bubbles usually mean too much air was incorporated or the milk was overheated. Good cappuccino foam should be thick and compact, while latte foam should be smooth and microfine.

Can you make latte art with a cappuccino?

It’s difficult to pour detailed latte art like tulips or leaves into a traditional cappuccino because of the thick foam. Most cappuccinos use simple designs or none at all. Wet cappuccinos with thinner foam can support basic latte art, but it’s easier in a latte.

How much espresso is in a cappuccino or latte?

Both drinks typically use a single or double shot of espresso—around 25–30ml. The espresso acts as the flavor base, balanced by the milk and foam. In competitions, some baristas use as little as 25ml to allow more room for milk and foam adjustments.
