How to Make Espresso: Start Here If You're New to Coffee Brewing

If you’ve ever ordered an espresso at a café and wondered how it’s made—or thought about skipping the shop and brewing it yourself—you’re not alone. Making espresso at home might seem intimidating, but it’s the foundation for almost every milk-based coffee drink and a great way to understand coffee better.

To make a classic espresso, you’ll need 9 bars of pressure, a 22–28 second extraction time, and around 30ml of dark, rich liquid topped with a layer of crema. That’s your starting point.

What Is Espresso, Really?

Espresso is a concentrated coffee brewed by forcing hot water through finely-ground coffee under high pressure—specifically, 9 atmospheres. The result is about 30ml of thick, dark coffee with a robust aroma and intense bitterness. Sitting on top is the crema: a reddish-brown foam that carries much of the drink’s aroma and texture.

Why Crema Matters in Espresso

Crema isn’t just for show—it’s a mix of emulsified coffee oils, carbon dioxide from fresh beans, and tiny air bubbles formed under pressure. It affects both flavour and appearance. Freshly roasted coffee with enough natural oils will produce a thicker, more stable crema. Darker, medium-to-medium-dark roasts tend to yield more crema than light roasts, which have fewer soluble oils and gases.

What You Need to Pull an Espresso Shot

To make espresso at home, you’ll need:

• A semi-automatic espresso machine capable of 9 bars of pressure
• A grinder that can produce a fine, consistent espresso grind
• Fresh coffee beans (ideally freshly roasted)
• A tamper to press the coffee down evenly
• Filtered water and a clean portafilter

The quality of your equipment and the freshness of your beans will dramatically affect the outcome. Don’t underestimate the importance of a good grinder—it’s arguably the most critical piece of the puzzle.

Step-by-Step: How to Make Espresso (Semi-Automatic Machine)

Once your setup is ready, follow these steps:

1. Grind your coffee beans to a fine consistency suitable for espresso—finer than table salt, but not powdered.
2. Dose the ground coffee into your portafilter—most home setups use around 18–20g, though exact dose varies by basket size.
3. Tamp the coffee evenly and firmly to create a level, compact puck. Uneven tamping leads to uneven extraction.
4. Lock the portafilter into the espresso machine.
5. Start the extraction. Aim for a 22–28 second brew time resulting in about 30ml of espresso.

The result should be a shot with a rich, dark brown body and a stable crema on top. If it runs too fast or tastes sour, your grind is likely too coarse. If it’s slow and bitter, it’s probably too fine or over-extracted.

Common Mistakes Beginners Make

Even with the right gear, beginners often run into issues:

• Using pre-ground coffee, which loses freshness quickly and often has the wrong grind size
• Not tamping evenly or with enough pressure
• Over- or under-dosing the coffee
• Using beans that are too light-roasted or not fresh enough to produce good crema
• Rushing the process without dialling in grind size and dose

Pulling a great shot takes practice. Don’t expect perfection on the first try—but with attention to detail, you’ll improve quickly.

Frequently Asked Questions

How much coffee do I use for one espresso shot?

Most home espresso setups use between 18–20 grams of coffee per shot, depending on your portafilter basket size. The exact dose can vary, but this range is a solid starting point for a standard double shot.

What grind size is best for espresso?

Espresso requires a very fine grind, similar to table salt or slightly finer. The coffee should be fine enough to create enough resistance for proper extraction under 9 bars of pressure within 22–28 seconds.

How long should an espresso shot take to pull?

A standard espresso shot should take between 22 and 28 seconds to extract. This time frame helps balance flavour, body, and crema. Too fast, and it will taste sour and weak; too slow, and it will be bitter and over-extracted.

Why is my espresso shot runny or weak?

A watery or weak espresso usually means the grind is too coarse, the dose is too low, or the tamp is too light. This causes the water to flow through too quickly, leading to under-extraction.

What is crema, and why is it important?

Crema is the golden-brown foam on top of a well-pulled espresso. It’s made up of emulsified oils, carbon dioxide, and air bubbles. Good crema improves aroma, flavour, and texture, and is a sign of fresh, properly extracted coffee.

Can I use any coffee beans for espresso?

While you can use any roasted coffee, espresso performs best with medium to medium-dark roasts that have sufficient oils and the right density for high-pressure brewing. Freshness is also key for good crema and flavour.
