What Is Espresso? A Complete Guide to Pulling the Perfect Shot
Espresso isn’t a type of bean or a roast level. It’s a brewing method that transforms finely ground coffee into a concentrated, complex shot in under 30 seconds. That simple distinction surprises many people who assume “espresso beans” are different from coffee beans. They aren’t. The magic lies in the technique.
This guide breaks down what espresso really is, why it stands apart from drip coffee, how much caffeine is in a shot, and what you need to start making it at home. And yes, Sabrina Carpenter’s Espresso turned the word into a pop hit, but for coffee lovers it will always mean that rich, crema-topped drink we know and love.
For an overview of all brewing styles, see our complete Coffee Brew Guide.
What Is Espresso?
Espresso is a concentrated coffee beverage brewed by forcing a small amount of nearly boiling water through finely ground coffee under high pressure. The result is a one-ounce shot topped with a reddish-brown foam called crema.
What makes espresso unique compared to other brewing methods:
- Pressure: Brewing under 8–10 bars of pressure is the defining characteristic.
- Grind: The grind is fine, almost powdery, which creates resistance for the water.
- Time: Extraction happens quickly, typically in 25–30 seconds.
- Result: A dense, complex shot with bold flavors balanced by subtle aromas.
This quick, pressurized extraction brings out layers of flavor that drip coffee cannot match.
How Much Caffeine in a Shot of Espresso
A single shot of espresso has about 60–70 mg of caffeine, and two shots (a double, or doppio) have roughly 120–140 mg. That is a little more than an 8-ounce cup of drip coffee, which averages about 95 mg.
For context:
| Drink | Serving Size | Average Caffeine |
| Espresso (single) | 1 oz | 60–70 mg |
| Espresso (double) | 2 oz | 120–140 mg |
| Drip coffee | 8 oz | ~95 mg |
| Cold brew | 12 oz | ~150–200 mg |
So ounce for ounce, espresso is more caffeinated. But because the serving size is so small, your morning mug of drip coffee usually delivers more total caffeine than a single shot.
How to Make Espresso at Home
Brewing espresso at home takes a little practice, but it isn’t as intimidating as it seems. With the right gear and a few consistent habits, you can pull café-worthy shots right from your kitchen.
What You’ll Need
- Espresso machine
- Burr grinder capable of a fine grind
- Freshly roasted coffee beans (start with an espresso blend)
- A tamper and a digital scale
The 4 Steps to a Perfect Shot
- Dose Your Coffee
Use the foundational 1:2 dose-to-yield ratio. A good starting point is 18 grams of finely ground coffee to produce a 36-gram double shot.
- Distribute and Tamp
Level the grounds evenly in the portafilter, then tamp firmly with even pressure. This creates resistance for the water, ensuring even extraction.
The right grind is essential. Learn more in our Master the Grind guide. - Pull the Shot
Lock in the portafilter and start brewing immediately. Aim for about 25–30 seconds of extraction to yield 36 grams of espresso.
- Taste and Adjust
– Sour or sharp → grind a little finer.
– Bitter or harsh → grind a little coarser.
– Thin body → increase dose slightly.
Espresso is a balance of time, grind, and pressure. Small adjustments make big differences.
Choosing the Best Coffee Beans for Espresso
The best beans for espresso are fresh, medium-dark to dark roasts with low acidity and a heavy body, which stand up to high-pressure extraction and build a rich crema. At Mōzza, we roast our Espresso Blend for exactly that: a balanced, chocolate-and-caramel shot that stays consistent cup after cup.
Any coffee can technically be brewed as espresso, but the high-pressure extraction method brings certain qualities to the forefront. The Mōzza philosophy is to offer blends that balance body, sweetness, and acidity so every shot feels complete.
- For a Classic, Rich Flavor: Choose a medium-dark or dark roast with chocolate and caramel notes. These create the traditional, velvety espresso profile.
- For a Brighter, Modern Shot: Try a medium-roast single origin if you enjoy more fruit-forward, acidic flavors. Lighter roasts can taste lively and complex when pulled well

Frequently Asked Questions
What is the difference between espresso and coffee?
All espresso is coffee, but not all coffee is espresso. Espresso is brewed under pressure in 25–30 seconds, producing a concentrated one-ounce shot.
Do I need an expensive machine to make good espresso?
Not necessarily. Higher-end machines offer more control and consistency, but many entry-level machines can make excellent espresso when paired with a good grinder and fresh beans.
What are common espresso drinks?
– Latte: espresso with steamed milk
– Cappuccino: espresso, steamed milk, and foamed milk in equal thirds
– Americano: espresso diluted with hot water
– Macchiato: espresso topped with a spoon of foam
How much caffeine is in two shots of espresso?
Two shots of espresso, known as a double or doppio, contain roughly 120–140 mg of caffeine. That is a little more than an 8-ounce cup of drip coffee, which averages about 95 mg.
Is espresso stronger than regular coffee?
Ounce for ounce, yes. Espresso is far more concentrated, so a one-ounce shot has more caffeine per ounce than drip coffee. But because a shot is so small, a full mug of drip coffee usually delivers more total caffeine.
Are espresso beans different from coffee beans?
No. There is no separate espresso bean. Any coffee bean can be brewed as espresso. Beans labeled espresso are simply roasted and blended to taste good under high-pressure extraction, usually a medium-dark to dark roast.
Final Sip
Espresso is a method, not a bean. It’s the art of harnessing pressure, heat, and grind precision to pull a shot that’s bold, complex, and layered with crema. With a little practice, you can master it at home and open the door to countless coffee drinks built on that one small shot.
