What is Espresso? A Complete Guide for Coffee Lovers
If you’re a coffee lover, chances are you’ve ordered a shot of espresso at a café, wanted to buy an espresso blend classic or enjoyed one as the heart of your favourite latte. But what is espresso, and why is it such a big deal in the coffee world? Espresso is more than a beverage, but a brewing method that has defined global coffee culture. Whether you’re in the business of espresso coffee beans or simply want to know how to make espresso coffee and how it differs from regular coffee, this guide breaks it all down.
Introduction: The Rationale for Making It Espresso
Espresso isn’t just a different way of making coffee; it’s the basis of almost every café standard from cappuccinos to macchiatos. It is robust, strong, and full-bodied, yet delivers complex flavours despite the small cup quantity. True fans of coffee call it the purest way to enjoy the taste of the bean, and that is why every coffee lover should know what it is.
What Exactly Is Espresso?
Espresso is concentrated coffee, produced by brewing finely ground coffee with hot water at high pressure. Unlike drip coffee, espresso is pulled within 25 to 30 seconds. The result is a small shot topped with thick crema, loved for its bold taste and smooth, creamy texture.
Espresso originated in Italy in the early 20th century, when Luigi Bezzera invented the first espresso machine in 1901. The Italian word “espresso” means “pressed out,” describing its preparation method. Since then, espresso has become the foundation of countless coffee drinks worldwide.
Espresso vs. Regular Coffee: A Comparison
- Brewing method: High pressure vs. slow drip

How Espresso Is Made
The Espresso Brewing Process
- Pressure: Standard 9 bars
- Temperature: 195–205°F water
- Extraction time: 25–30 seconds
A balanced shot depends on grind size, tamping pressure, and the freshness of beans.
The Role of Espresso Machines
Espresso wouldn’t exist without its machines. From traditional lever machines to today’s fully automatic models, the principle remains the same—coffee brewed under pressure for maximum flavour and rich crema.
Coffee Beans for Espresso
- Dark roast delivers hearty, chocolate flavours
