Types of Coffee Drinks, Their Layers, and Caffeine Content

Ever stood in a coffee shop menu unsure whether to order a latte, macchiato, or flat white? Whether you're trying to figure out which drink has the most kick or simply curious how your favorite coffee is actually made, understanding the differences between coffee types helps you choose—and appreciate—what you're drinking.

The key differences come down to espresso shots, milk ratios, and foam layers. For example, an espresso is just a single or double shot (about 30ml), while a latte includes two parts steamed milk and one part espresso, topped with milk foam. Each drink has a distinct caffeine level, texture, and flavor profile based on its composition.

What Is Espresso?

Espresso (pronounced ess-press-oh) is the foundation of many coffee drinks. It’s a small, concentrated shot of coffee made by forcing hot water through finely-ground coffee under high pressure. A standard single shot uses about 7–10g of coffee and produces roughly 30ml (1oz) of espresso. It’s meant to be sipped quickly while hot. Espresso can also serve as the base for almost all other coffee drinks.

Common Espresso-Based Drinks and Their Layers

Here’s how some of the most common espresso-based drinks are structured:

Espresso Macchiato

An espresso macchiato—Italian for “stained” or “marked”—is a single or double shot of espresso with just a small amount of steamed milk or milk foam added (usually a spoonful), ‘marking’ the espresso. This drink emphasizes the espresso flavor with just a hint of milk.

Caffè Latte (Latte)

A latte, short for caffè latte or “milk coffee,” consists of one shot of espresso (sometimes two), two parts steamed milk, and a thin layer of milk foam on top. The typical ratio is 1:2:1 (espresso:milk:foam). It’s creamy and mild compared to straight espresso.

In some variations, a latte might include up to two and a half parts of heated milk and foam combined with one shot of espresso.

Cappuccino

A traditional cappuccino is made with one shot of espresso, equal parts steamed milk and milk foam—commonly a 1:1:1 ratio. It usually features a layer of milk foam on top, and sometimes includes a dusting of chocolate powder or a drizzle of chocolate syrup. In the source description, there’s also mention of adding more than one shot of espresso and even extra water, though that’s non-standard.

Café Breve

A café breve is made with espresso and half-and-half (light cream) instead of whole milk. It typically includes one shot of espresso, steamed half-and-half, and foam. It’s richer and creamier than a latte due to the higher fat content of the dairy used.

Caffè Mocha (Mocha)

A mocha combines espresso, steamed milk, and chocolate—either cocoa powder or chocolate syrup. It’s essentially a chocolate-flavored latte and often topped with whipped cream. The drink balances coffee bitterness with sweet chocolate flavor.

Americano

An Americano is made by diluting a shot or two of espresso with hot water. The result is a coffee similar in strength to drip coffee but with a different flavor profile due to the espresso base. There’s no milk involved unless added by the drinker.

Coffee Drink Caffeine Content

While exact caffeine levels vary based on factors like bean origin, roast level, and extraction time, here’s a general idea of caffeine content per drink (based on standard recipes and single or double espresso bases):

• Espresso (single shot): ~63mg caffeine
• Espresso (double shot): ~125mg caffeine
• Americano (1 shot espresso + water): ~63–125mg depending on number of shots
• Latte (1 shot espresso + milk): ~63–125mg
• Cappuccino (1 shot espresso + milk/foam): ~63–125mg
• Mocha (1 shot espresso + chocolate + milk): ~63–125mg + chocolate calories
• Macchiato (1 shot + minimal foam): ~63–125mg

Note: Most of these drinks contain one or two espresso shots, with the rest of the caffeine coming from additional shots if used. Milk, foam, and flavorings do not add caffeine.

How to Tell These Coffees Apart

The main differences between these drinks lie in their preparation: the number of espresso shots, the amount and temperature of milk, and the presence or absence of foam or chocolate. Espresso is coffee in its most concentrated form. Lattes and cappuccinos balance espresso with steamed milk and foam in different proportions. Macchiatos are espresso-forward with just a touch of milk. Americanos are diluted espresso with hot water, and mochas add chocolate for sweetness.

Frequently Asked Questions

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

A latte has more steamed milk and a thinner layer of foam (ratio around 1:2:1 espresso:milk:foam), making it creamier and milder. A cappuccino has equal parts espresso, steamed milk, and foam (1:1:1), giving it a stronger coffee flavor and a lighter, airier texture.

Does an espresso have more caffeine than a latte?

A single shot of espresso has about 63mg of caffeine, while a latte usually contains one or two shots. So a latte has roughly the same or slightly more caffeine, but it’s diluted with milk, making it taste less strong.

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

A macchiato is mainly espresso with just a small amount of milk or foam added, keeping the coffee flavor intense. A latte is mostly steamed milk with one or two shots of espresso, resulting in a much milder and creamier drink.

Is a mocha just a chocolate latte?

Essentially, yes. A mocha is a latte with added chocolate syrup or cocoa, combining coffee and chocolate flavors. It often includes whipped cream and is sweeter than a regular latte.

Why does an Americano taste different from brewed coffee?

An Americano is made from espresso shots diluted with hot water. The espresso brewing process extracts flavors differently than drip brewing, often resulting in a richer, more intense taste despite similar strength.
