How to Use and Clean an Espresso Machine for Specialty Coffee

If you’ve just bought a specialty espresso machine or are trying to improve your home setup, you probably have one big question: how exactly do I use this thing—and then how do I clean it without ruining anything? The good news is that while there are many types of machines, the core steps for making espresso and maintaining the machine are consistent across models. Here’s exactly how to do it right.

In short: Grind fresh coffee, tamp it evenly in the filter basket, lock the portafilter into the machine, and press the button to extract. After brewing, remove the portafilter, knock out the puck, and rinse everything. Regular cleaning prevents buildup and ensures consistent shots.

Understanding Your Espresso Machine

Espresso machines come in many designs, but the basic components and workflow are similar across most models. Whether it’s a manual lever machine or an electric pump-driven model, the key steps—grinding, dosing, tamping, and extracting—remain essential for producing a quality shot. Understanding these universal elements will help you operate any espresso machine more confidently.

How to Prepare and Use the Coffee Filter Basket

The coffee filter basket is typically housed inside a plastic handle, often referred to as the portafilter. The basket itself is made of stainless steel and features a dense array of tiny holes designed to allow brewed coffee to pass through while trapping the coffee grounds. This is where you place your ground coffee before tamping.

Step-by-Step: Making Espresso

Here’s how to make espresso using a standard machine with a portafilter system:

• Grind the Coffee: Begin by grinding your coffee beans to a fine espresso grind. The fineness of the grind directly affects extraction time and flavor, so aim for a consistency similar to table salt.
• Dose the Coffee: Measure out a single shot’s worth of coffee—roughly the amount that fills the portafilter basket. This is typically around 18–20 grams, though exact amounts depend on your basket size.
• Level and Tamp: Distribute the grounds evenly in the basket. Lightly tap the portafilter on the counter a few times to settle the coffee, then use a tamper (often included with the machine) to press down evenly. Apply firm, consistent pressure—not too light, not too hard. This step is crucial for even extraction.
• Attach the Portafilter: Align the portafilter with the machine’s group head. Twist it in until it locks securely. Most machines have a threaded or spring-loaded connection that clicks into place. Make sure it’s fully seated to prevent leaks under high pressure.
• Extract the Espresso: Press the extraction button. Many machines feature multiple buttons for different shot volumes—single, double, or ristretto (concentrated shot). The machine is usually pre-set for standard volumes. The high-pressure water will flow through the coffee grounds and extract the espresso into your cup.

Cleaning the Machine After Use

Once you’ve pulled your shot, immediate cleaning helps maintain machine performance and hygiene:

• Remove the Portafilter: Take out the portafilter as soon as the shot is complete. The coffee puck (used grounds) will be left behind.
• Knock Out the Puck: Tap the portafilter gently on a knock box or sturdy surface to dislodge the coffee puck. Avoid using excessive force that could damage the basket.
• Rinse the Portafilter and Basket: Rinse both the portafilter and the filter basket under hot water to remove coffee oils and residue. Avoid using soap unless absolutely necessary, as residues can affect taste.
• Wipe Down the Group Head: Use a clean cloth to wipe the group head where the portafilter sits. This prevents old coffee oils from building up and affecting future extractions.

Frequently Asked Questions

What kind of coffee grind should I use for espresso?

Use a fine grind, similar to table salt. The exact grind size may vary depending on your beans and machine, but it should be fine enough to slow water flow and allow proper extraction, typically taking 25–30 seconds for a standard double shot.

How much coffee should I put in the portafilter basket?

For a single shot, use around 7–10 grams; for a double shot, use approximately 18–20 grams. The exact dose depends on your basket’s size and the recipe you’re following. Fill the basket without overcompressing before leveling and tamping.

How hard should I tamp the coffee?

Tamp with firm, even pressure. The goal is a level, compact bed of coffee about 9–10 bars of pressure resistance. Avoid tamping too lightly (which causes uneven extraction) or too hard (which can slow flow excessively).

Do I need to clean the machine after every use?

Yes. You should remove the puck immediately after brewing and rinse the portafilter and basket. A full backflush with water (or cleaner, if needed) is recommended regularly—at least once a week depending on usage—to prevent coffee oil buildup.

What is a coffee puck and why should I remove it?

The coffee puck is the compacted mass of used coffee grounds left in the portafilter basket after extraction. Leaving it in the basket can cause stale flavors and mold. Removing it promptly keeps your equipment clean and your future shots tasting better.
