Making a strong espresso with a DeLonghi machine is an art that combines the right equipment, quality beans, and precise technique. Whether you’re a beginner or a seasoned coffee enthusiast, mastering the process will help you brew rich, bold espresso shots every time. This guide covers everything from choosing the right machine to perfecting your extraction.
Choosing the Right DeLonghi Espresso Machine
DeLonghi offers a range of espresso machines, from manual to fully automatic models. For a strong espresso, semi-automatic or manual machines provide the most control over extraction. Popular models like the DeLonghi Dedica or La Specialista allow you to adjust grind size, tamping pressure, and water temperature—key factors in brewing a robust shot.
If you prefer convenience without sacrificing strength, a super-automatic machine like the DeLonghi Magnifica can still deliver a powerful espresso with customizable settings. Whichever model you choose, ensure it has a high-pressure pump (at least 9 bars) for optimal extraction.
Selecting the Best Coffee Beans
The strength of your espresso starts with the beans. For a bold flavor, choose dark roast beans with low acidity and rich, chocolaty or nutty notes. Single-origin beans from regions like Brazil or Sumatra often work well, but espresso blends designed for intensity are also a great choice.
Always use freshly roasted beans—preferably within two to four weeks of the roast date—and grind them just before brewing. Stale or pre-ground coffee will result in a weak, flat-tasting espresso.
Grinding Coffee for Strength
A fine, consistent grind is essential for strong espresso. If the grind is too coarse, water will pass through too quickly, producing a weak shot. If it’s too fine, over-extraction can make the espresso bitter.
Invest in a quality burr grinder and set it to a fine espresso grind. Adjust slightly based on your machine’s performance—if the shot pulls too fast, go finer; if it drips too slowly, go coarser.
Dosing and Tamping Properly
The amount of coffee you use (dose) and how you tamp it directly affect strength. A standard double shot requires about 18–20 grams of coffee. Use a scale to measure accurately, as guessing can lead to inconsistent results.
After dosing, distribute the grounds evenly in the portafilter and tamp with firm, even pressure (about 30 pounds). An uneven tamp causes channeling, where water bypasses some grounds, weakening the shot.
Setting the Right Water Temperature
DeLonghi machines typically heat water to between 195°F and 205°F, ideal for espresso extraction. If your machine allows temperature adjustment, aim for the higher end of this range for a stronger, more full-bodied shot.
Always preheat your machine and portafilter by running a blank shot (without coffee) to stabilize the temperature. Cold equipment can lead to under-extraction.
Pulling the Perfect Shot
Insert the portafilter, start the extraction, and aim for a 25–30 second pull for a double shot. The espresso should flow like warm honey, starting with a dark, thick stream that lightens toward the end.
If the shot finishes too quickly (under 20 seconds), it will taste weak—adjust the grind finer or increase the dose. If it takes too long (over 35 seconds), it may taste bitter—grind coarser or reduce the dose slightly.
Maintaining Your Machine for Consistent Strength
Regular cleaning and descaling keep your DeLonghi machine performing at its best. Residual coffee oils and mineral buildup can affect flavor and extraction. Clean the portafilter, group head, and steam wand daily, and descale every 1–3 months depending on water hardness.
Troubleshooting Weak Espresso
If your espresso lacks strength, check these common issues:
Grind size: Too coarse, leading to fast extraction.
Dose: Too little coffee in the portafilter.
Tamping: Uneven or insufficient pressure.
Beans: Stale or low-quality coffee.
Adjust one variable at a time to identify the problem.
Enhancing Espresso Strength with Advanced Techniques
For an even bolder shot, try these methods:
Ristretto: Use the same dose but halve the water for a more concentrated shot.
Pre-infusion: If your machine supports it, pre-infuse the grounds for a few seconds to saturate them evenly before full extraction.
Blending beans: Mix a small amount of robusta beans with arabica for extra caffeine and intensity.
Conclusion
A well-made strong espresso should have a rich crema, full body, and deep flavor. Sip it straight to appreciate its intensity or use it as a base for lattes and cappuccinos.
By following these steps and fine-tuning your technique, you’ll consistently brew strong, delicious espresso with your DeLonghi machine. Happy brewing!
