Popular Coffee Types Explained: From Espresso to Irish Coffee

Ever stood in line at a coffee shop unsure whether to order a macchiato or a flat white? With so many coffee styles on the menu—each with different ratios, brewing methods, and flavor outcomes—it’s easy to feel overwhelmed. But knowing what’s actually in your cup helps you choose the drink that best suits your taste and mood.

In short: there are at least nine common coffee types covered here. Espresso is a 1/4-ounce shot brewed under high pressure; a macchiato tops that with a small layer of milk foam; an Americano is diluted espresso; and drinks like cappuccino, latte, and mocha combine espresso with varying amounts of steamed milk and foam. There’s also white coffee from Malaysia, Ireland’s whiskey-laced coffee, and Vienna’s whipped cream-topped brew.

What Is Espresso and How Is It Made?

Espresso is the foundation of many coffee drinks. It is made by forcing nearly boiling water (around 90–96°C) through finely ground coffee under high pressure (9–10 bar) for about 20–30 seconds. The result is a small shot—about 1/4 ounce (7–30 mL)—of thick, concentrated coffee with a rich crema on top. It has a bold, bitter flavor and high caffeine density per volume. This style is used as the base for many other drinks including cappuccinos, lattes, and macchiatos.

What’s the Difference Between a Macchiato, Americano, and Cappuccino?

A macchiato, meaning “stained” in Italian, is a shot of espresso with just a small amount of steamed milk or milk foam added—typically a teaspoon or less—to slightly lighten the color (‘mark’) the coffee. This enhances the espresso’s aroma while softening its intensity. It usually keeps the volume under 1.5 ounces.

An Americano is made by diluting a shot or two of espresso with hot water, resulting in a drink similar in strength to but different in mouthfeel from standard drip coffee. It’s milder in taste but retains a higher caffeine level due to the espresso extraction process. The ratio varies, but typically it’s 1:3 to 1:5 espresso to water.

A cappuccino combines one shot of espresso with nearly equal parts steamed milk and milk foam—roughly 1/3 espresso, 1/3 steamed milk, and 1/3 foam. This creates a balanced drink with a creamy texture and rich flavor. Traditionally, it’s served in a smaller cup and is known for its velvety microfoam top.

More Coffee Styles: Latte, Mocha, Flat White & More

A latte (or caffè latte) is made with a shot of espresso and a larger amount of steamed milk—usually around 2/3 of the drink—with just a thin layer of foam on top. It’s creamier and milder than a cappuccino, often customized with syrups or alternative milks.

A mocha blends espresso with chocolate syrup or cocoa powder, then adds steamed milk and sometimes whipped cream. It’s essentially a chocolate-flavored latte and a favorite for those who enjoy sweet coffee drinks.

A flat white originates from Australia or New Zealand and is similar to a latte but uses ristretto shots and microfoam for a denser, velvety texture with less volume and a stronger coffee flavor.

White coffee, a specialty from Malaysia, is made with specially selected coffee beans and premium defatted milk powder. It undergoes a unique roasting and brewing process that results in a lighter-colored, smoother, and gentler cup compared to traditional black coffee. It preserves much of the original coffee aroma without irritating the stomach.

The Irish coffee is a warming cocktail-style drink combining hot coffee, Irish whiskey, sugar, and topped with whipped cream. It straddles the line between beverage and digestif, offering a sweet, boozy twist on hot coffee.

The Viennese coffee involves pouring strong black coffee into a cup pre-coated with sugar or rock candy crystals. It’s then topped with two spoonfuls of cold fresh cream, creating a dessert-like experience that contrasts hot coffee with cool, smooth cream.

Brewing Methods Behind the Drinks

Most of these coffee styles start with an espresso shot—made using a machine that pushes water through compacted coffee grounds at high pressure. For Americanos, the espresso is simply diluted with hot water. Milk-based drinks like lattes, cappuccinos, and macchiatos involve steaming and frothing milk to various textures using steam wands. Some drinks, like white coffee, rely on unique roasting and brewing methods outside the espresso tradition, often involving special grinders or preparation techniques developed regionally.

Frequently Asked Questions

What is the main difference between espresso and Americano?

Espresso is a concentrated shot of coffee made with pressurized water, yielding about 1/4 ounce of strong, bold liquid. An Americano is made by adding hot water to espresso, stretching the volume and lowering the intensity while keeping a relatively high caffeine content.

How is a macchiato different from a latte?

A macchiato is a shot of espresso with just a small amount of milk or foam added, keeping it mostly espresso-flavored and strong. A latte combines espresso with a large proportion of steamed milk and a little foam, resulting in a creamier, milder drink.

What’s the traditional ratio for a cappuccino?

A traditional cappuccino consists of equal thirds: 1/3 espresso, 1/3 steamed milk, and 1/3 milk foam. This balance gives it a rich espresso flavor with a creamy, airy texture.

What makes white coffee different?

White coffee is a Malaysian-style brew made with special coffee beans and defatted milk powder. It is processed differently to create a lighter-colored, smoother, and easier-on-the-stomach coffee that retains the aroma without the usual bitterness.

Does an Irish coffee contain alcohol?

Yes, an Irish coffee contains Irish whiskey along with hot coffee, sugar, and whipped cream. It’s a warm, sweet, and boozy drink rather than a standard caffeine beverage.

What coffee is used in a traditional Viennese coffee?

A Viennese coffee is made with strong black coffee poured over sugar crystals at the bottom of the cup, then topped with cold fresh cream. The type of coffee isn’t specified, but it’s typically a dark, strong brewed coffee.
