Coffee Basics: Espresso vs Strong Brewed Coffee

Coffee basics recipes often call for either a double shot of espresso or a cup of strong brewed coffee. At first glance, they may seem interchangeable, but they are two very different things. Understanding the difference helps you make better coffee at home and ensures your recipes turn out as intended.

This article breaks down what sets espresso and brewed coffee apart, from brewing method to flavor, caffeine content, and how to use each one. By the end, you’ll know exactly which to use and why.

What is Espresso?

Espresso is a concentrated form of coffee created by forcing hot water through finely ground coffee beans under high pressure. This unique process extracts rich flavors, oils, and aromas that give espresso its intense taste and velvety texture.

• Serving size: A single shot is about 30ml (1 oz). A double shot is 60ml (2 oz).
  
• Flavor: Bold, rich, slightly thicker than regular coffee, with a layer of crema (golden foam) on top.
  
• Brewing method: Requires an espresso machine to apply 9 bars of pressure.
  
• Uses: It’s the foundation of lattes, cappuccinos, flat whites, mochas, macchiatos, and other espresso-based drinks.
  

Espresso is prized for its intensity. Though small in volume, it delivers a full-bodied coffee experience.

What is Strong Brewed Coffee?

Strong brewed coffee, sometimes referred to as “regular coffee made strong,” is prepared using slower brewing methods such as drip, pour-over, French press, or AeroPress. The “strength” comes from adjusting the coffee-to-water ratio rather than pressure.

• Serving size: A typical cup is around 240ml (8 oz), though mugs are often larger.
  
• Flavor: Milder and less concentrated than espresso, but still flavorful. It has a lighter body and lacks crema.
  
• Brewing method: Hot water extracts coffee slowly through immersion or drip.
  
• Uses: Commonly enjoyed as an everyday drink, served black or with milk. Also used in recipes like iced coffee, cold brew, or desserts such as tiramisu.
  

The key difference is that brewed coffee is about volume and comfort, while espresso is about concentration and intensity.

Key Differences Between Espresso and Strong Brewed Coffee

Feature	Espresso	Strong Brewed Coffee
Brewing Method	High pressure (espresso machine)	Drip, pour-over, French press, etc.
Serving Size	30–60ml (1–2 oz)	240ml+ (8 oz or more)
Flavor Profile	Bold, concentrated, thick with crema	Smooth, lighter, more diluted
Caffeine (avg.)	60–80mg per shot	90–120mg per 8 oz cup
Common Uses	Espresso drinks (lattes, cappuccinos)	Daily coffee, iced coffee, desserts

Caffeine Comparison

A single shot of espresso may taste stronger, but because it’s smaller, it actually contains less total caffeine than a full cup of brewed coffee.

• Espresso: 60–80mg caffeine per shot
  
• Double shot: 120–150mg caffeine
  
• Brewed coffee (8 oz): 90–120mg caffeine
  

This means if you sip one espresso shot, you’ll get an intense hit of flavor and a quick lift. But if you drink a full cup of strong coffee, you’ll take in more caffeine overall.

When to Use Espresso vs Strong Brewed Coffee

Use espresso when:

• You’re making specialty drinks like lattes, cappuccinos, or mochas.
  
• You want intensity in a small volume.
  
• A recipe specifies “a shot of espresso” (often for desserts like affogato).
  

Use strong brewed coffee when:

• You’re brewing a standard cup to drink black or with milk.
  
• Recipes need more liquid volume (e.g., iced coffee, marinades, or cakes).
  
• You don’t have an espresso machine but want bold flavor.
  

Coffee Basics:Can You Substitute One for the Other?

Sometimes you can, but with adjustments.

• If a recipe calls for espresso and you only have brewed coffee, make it extra strong by using a higher coffee-to-water ratio.
  
• If a recipe calls for brewed coffee and you only have espresso, dilute the espresso with hot water to approximate a cup (similar to an Americano).
  

The taste won’t be identical, but it will work in most recipes.

Final Thoughts

Espresso and strongly brewed coffee may share the same beans, but they offer completely different experiences. Espresso is small, concentrated, and intense, the foundation of specialty café drinks. Strong-brewed coffee is larger, smoother, and suited for everyday sipping.
