Part 1: Foundations of Coffee and Espresso

The main difference between espresso and coffee is the brewing method. Espresso is a concentrated shot of coffee made by forcing hot water through finely ground coffee beans at high pressure, typically resulting in a small, strong shot with a layer of foam known as crema on top. On the other hand, coffee is brewed using various methods, such as drip, French press, or pour-over, and can be diluted or concentrated depending on the brewing process. Espresso beans are not different from regular coffee beans; it’s the roast and grind that make the difference.

What is Coffee?

Coffee comes from the roasted seeds of fruit grown on flowering plants called coffee trees or bushes. There are many species of coffee trees, but Coffea arabica and Coffea robusta are the two most commonly cultivated for commercial coffee production. Coffee trees originated in Ethiopia and were first cultivated for human consumption in Yemen. The stimulating effects of coffee beans were likely first discovered when animals ate the cherries and experienced increased energy. Today, coffee is one of the most beloved and widely consumed drinks around the world.

What is Espresso?

Espresso is a concentrated form of coffee made by forcing hot water under high pressure through very finely ground coffee beans. This brewing method yields a thicker, syrupy coffee concentrate with a bold, intense flavor. The word “espresso” means “pressed out” in Italian, referring to the pressure process used to create this special type of coffee. While regular coffee is brewed using gravity, filtering water through the grounds, espresso relies on at least 9 bars of pressure to produce its characteristic concentration and complex flavors. A shot of espresso contains less liquid than a cup of coffee but packs in more caffeine and coffee essence.

The Brewing Process

Coffee and espresso may start from the same magic bean, but how you unlock their flavors makes all the difference.

To brew coffee, you first have to grind the roasted beans to break them down for even water extraction. The grind size can be adjusted from fine to coarse depending on the brew method. For drip machines, a medium grind is common, while French press uses a coarser texture. Ground coffee is then combined with hot water, usually around 200°F, allowing the water to extract the coffee’s aromatic oils, acids, and compounds. Gravity draws water down through the grounds to produce coffee.

Espresso requires an extremely fine, powdery grind to maximize extraction. Hot water from the espresso machine flows through the tamped down grounds at high pressure, producing a concentrated liquid espresso. Pressure, grind size, and water temperature are key factors impacting flavor in espresso. But that’s not all – the roast level also significantly influences the tastes you’ll experience from bean to cup.

Grind Size, Water Quality, and Pressure

When brewing coffee or pulling espresso shots, focus on these key factors for quality:

Grind Size – Consistent, uniform grinding and the right grind size for the brew method are critical. Generally, finer grinds extract more flavor. Espresso requires an ultra-fine powdery grind while French press uses a coarse grind.

Water Quality – For balanced extraction and flavor, start with fresh cold water. Soft water is ideal, while hard water can result in a bitter taste. Filters can remove impurities affecting taste.

Pressure – Espresso requires at least 9 bars of pressure for proper extraction, while drip coffee relies solely on gravity. High pressure unlocks espresso’s signature crema topping and bold flavors.

Mastering grind size for your brew method, using proper water, and applying adequate pressure makes all the difference between good and great coffee.
