10 Classic Espresso-Based Coffees Explained

Ever walked into a café and stared at the menu, wondering what really separates a flat white from a latte—or why your dirty coffee looks murkier than the last one? Whether you're ordering at a shop or brewing at home, knowing how these drinks are built makes all the difference in taste, texture, and technique.

FrontStreet Coffee outlines 10 classic espresso-based drinks, each with exact ingredient ratios, textures, and serving methods. From the 40g double espresso base to a 0.5cm microfoam cap on an Australian flat white, here’s the precise breakdown every coffee enthusiast should know.

What Is Espresso?

Espresso is the foundation of nearly all these drinks. It’s a 9-bar-pressure extraction where hot water (around 90–96°C) passes rapidly through finely-ground coffee (typically 20g dose), producing about 40g of concentrated liquid in roughly 25–30 seconds. The result: a thick, aromatic shot with a rich crema—often described as bittersweet with caramelized undertones. At FrontStreet, the signature 40g double espresso forms the baseline for almost all milk and mixed drinks.

Diluted & Straightforward: Americano & Espresso Basics

The Americano is simply a diluted espresso: 40g of double espresso mixed with 180ml hot water, creating a 220ml drink with a 1:4.5 brew ratio. This style mellows the intensity while preserving aroma—ideal for those who prefer a less punchy cup. It’s fundamentally different from filter coffee, offering espresso-like body without the crema.

Milk-Based Drinks: Texture, Ratios & Layers

These drinks vary mostly by milk volume, foam thickness, and serving size. Here’s how the standards break down:

Latte (Caffè Latte)

Made with a 40g double espresso, 260g steamed milk, and 1cm of foam. The drink emphasizes smooth milk flavor balanced with espresso. It’s ideal for latte art thanks to its milk texture and volume.

Cappuccino

Traditional cappuccinos use a 1:1:1 ratio: one shot espresso, equal parts steamed milk, and thick foam. FrontStreet pours one 40g shot into a 180ml tulip cup, then adds dense, velvety milk foam. The thicker foam gives it a heartier mouthfeel and more coffee-forward flavor than a latte.

Flat White

This smaller-format Australian-style drink uses 30g espresso in a 220ml glass, with 190ml milk and just 0.5cm microfoam (achieved by steaming 5.5–6 parts milk from an initial 5 parts). The reduced foam highlights a stronger espresso presence and is served only hot.

Australian-Style Dirty Coffee

A “refined” ice latte, the dirty coffee involves pouring 40g hot espresso over 150g cold milk in a chilled glass—without ice. The key is minimal distance (around 1cm) between the espresso spout and milk surface, allowing the hot coffee to slowly sink and create visual 'dirty' layering. Served unstirred for a contrast of hot and cold flavors.

Smaller or Specialty Milk Drinks

Macchiato (‘Marked’ Espresso)

A traditional macchiato consists of 40g espresso ‘marked’ with a spoonful of delicate milk foam. It’s essentially a shot with just enough milk to alter its color slightly—highlighting the crema and adding a touch of softness without overpowering the espresso.

Mocha (Moka / Chocolate Espresso)

Combining espresso with chocolate and milk, FrontStreet’s version uses 40g espresso, 20g chocolate syrup, and 260g hot milk. It’s a sweet, indulgent drink where coffee, cocoa, and dairy blend into a dessert-like profile. Variants include white chocolate mochas or ‘zebra’ versions mixing both chocolates.

Affogato

An affogato is not mixed but layered: a shot of espresso poured over a single vanilla ice cream scoop. Served in a cup or bowl, it’s a cold, creamy, sweet contrast to the hot coffee—perfect for warm weather or dessert service.

Caramel Macchiato (Starbucks-Style)

Though not originally Italian, the ubiquitous caramel macchiato is included here for completeness. A 355ml (medium) Starbucks version contains around 30ml espresso alongside 300ml steamed milk, vanilla syrup, and caramel drizzle. It shares similarities with a wet cappuccino or a sweetened latte, emphasizing flavor layers over pure espresso clarity.

Frequently Asked Questions

What’s the difference between a latte and a flat white?

A flat white uses less milk (190ml vs 260ml in a latte) and thinner microfoam (0.5cm vs 1cm), resulting in a stronger espresso flavor. Flat whites are also served hot and typically in smaller glass cups, emphasizing the coffee’s taste over milk texture.

How much espresso is in a standard double shot?

At FrontStreet Coffee, a double shot is 40g of extracted coffee from a 20g coffee dose, brewed under 9-bar pressure. This 40g yield is the base for most drinks, including lattes, cappuccinos, and americanos.

Why does dirty coffee look ‘dirty’?

The ‘dirty’ effect comes from the visual layering of hot espresso poured over cold milk without stirring. The temperature difference creates slow blending, and the unmixed layers appear murky or muddy—especially if viewed through the glass before stirring.

What’s the ideal foam thickness for a cappuccino?

A traditional cappuccino uses thick, dry foam around 1cm thick. FrontStreet achieves this by fully frothing milk to a velvety texture, which contrasts with the thinner microfoam used in lattes or flat whites.

Can I make an americano with any espresso?

Yes, but the resulting flavor depends heavily on the espresso’s quality. FrontStreet emphasizes that poorly extracted espresso leads to a dull americano. Their 40g double shot, known for rich crema and balanced bitterness, makes a notably better diluted cup.
