Espresso is a strong, concentrated coffee made by forcing hot water through finely ground coffee beans under high pressure. It’s not a specific bean or roast but a brewing method that produces a small, intense shot—usually 1 to 2 ounces—topped with a frothy layer called crema.
If you’ve ever wondered what makes espresso different from regular coffee or how to enjoy it, you’re in the right place. Let’s break down its history, features, brewing process, and the many drinks it inspires.
What Makes Espresso Special?
Espresso stands out for its bold flavor and smooth texture. The high-pressure brewing process preserves the coffee’s natural oils and aromas, which often fade in slower methods like drip coffee. A good shot of espresso has a rich, complex taste that might include notes of chocolate, nuts, fruit, or spices, depending on the beans used. It’s less acidic than regular coffee because the grounds spend less time in contact with water, resulting in a thicker, almost syrupy feel in your mouth.
Any coffee bean can make espresso, but many baristas prefer Arabica for its smooth, nuanced flavors or a mix of Arabica and Robusta for a stronger taste and thicker crema. The key is using fresh, high-quality beans and grinding them fine, like table salt, to maximize flavor extraction.
A Brief History of Espresso
Espresso was born in Italy, where speed and quality shaped its creation. In 1884, Angelo Moriondo patented the first steam-driven coffee machine in Turin, designed to brew coffee faster for busy workers. In 1901, Luigi Bezzera improved the design, creating a machine closer to today’s models. By 1906, Desiderio Pavoni marketed these machines, and “caffè espresso” became a staple in Italian cafés.
In the 1950s, espresso spread to the U.S., especially among Italian communities in cities like New York and San Francisco. The latte, possibly invented in Berkeley, California, helped make espresso mainstream. Today, thanks to chains like Starbucks and the third-wave coffee movement, espresso is a global favorite, enjoyed in artisanal cafés and home kitchens alike.
How Is Espresso Made?
Making espresso is quick but precise. An espresso machine forces hot water (195–205°F) through a tightly packed “puck” of finely ground coffee at 9–10 bars of pressure. The process takes 20–30 seconds and yields a 1-ounce single shot or a 2-ounce double shot. Here’s a simple breakdown:
- Grind the Beans: Use a fine grind, similar to table salt, for optimal extraction.
- Tamp the Grounds: Pack 7–9 grams (single) or 14–18 grams (double) into the portafilter evenly with firm pressure.
- Brew the Shot: Lock the portafilter into the machine, place a cup underneath, and start the extraction. The coffee should flow like warm honey.
- Serve Immediately: Espresso is best fresh, with a thick, golden-brown crema on top.
The crema, a frothy layer unique to espresso, forms when high pressure releases carbon dioxide trapped in coffee oils. It should be dense and last a few minutes, not 40 minutes as sometimes claimed. Light, bubbly crema suggests under-extraction (weak flavor), while dark, thin crema indicates over-extraction (bitter taste).
Espresso vs. Regular Coffee
Espresso and drip coffee differ mainly in their brewing methods. Drip coffee slowly filters hot water through coarser grounds, taking up to 10 minutes to brew 6–8 ounces. Espresso’s high-pressure process is faster, producing a smaller, stronger drink. Despite its intensity, a 1-ounce espresso shot has less caffeine (29–100 mg) than an 8-ounce drip coffee (95–200 mg). Double shots or café drinks like lattes may have more caffeine, depending on the recipe.
Popular Espresso Drinks
Espresso is the base for many café favorites. Here’s a quick guide to common variations, with a chart comparing their ingredients:

| Ristretto | 0.5 oz | None | None | Less water, stronger | 0.5 oz |
| Lungo | 2 oz | None | None | More water, milder | 2 oz |
| Cappuccino | 2 oz | 2 oz | 2 oz | None | 6 oz |
| Latte | 2 oz | 10 oz | 0.1 oz | None | 12 oz |
| Americano | 2 oz | None | None | 3 oz hot water | 5 oz |
| Flat White | 2 oz | 4 oz | Thin layer | None | 6 oz |
| Mocha | 2 oz | 1 oz | None | 2 oz chocolate | 5 oz |
| Café con Hielo | 2 oz | None | None | Ice | 2 oz |
| Affogato | 2 oz | None | None | Vanilla ice cream | ~4 oz |
| Con Panna | 2 oz | None | None | Whipped cream | ~3 oz |
- Doppio: A double shot (2 oz), same strength as a single shot, just larger.
- Ristretto: Half the water (0.5 oz), twice the intensity.
- Lungo: Double the water (2 oz), milder flavor.
- Cappuccino: Equal parts espresso, steamed milk, and foam for a creamy balance.
- Latte: More steamed milk for a milder taste, often with latte art.
- Americano: Diluted with hot water, similar to drip coffee.
- Flat White: Less milk than a latte, stronger coffee flavor.
- Mocha: Sweet and chocolatey, perfect for dessert lovers.
- Iced Options: Café con hielo (espresso over ice), affogato (espresso over ice cream), or con panna (espresso with whipped cream) offer cool, indulgent twists.
Tips for Enjoying Espresso
- Sip Slowly: Espresso’s bold flavor is best savored in small sips. Try it black to appreciate its complexity.
- Cleanse Your Palate: Many cafés serve sparkling water with espresso to refresh your taste buds before drinking.
- Experiment at Home: Invest in a quality espresso machine and fresh beans. Adjust grind size, tamping pressure, and brew time to perfect your shot.
- Pair It Up: Espresso pairs well with pastries like biscotti or a slice of dark chocolate.
