If you want to improve your espresso taste, start by getting to know your espresso machine. Commercial coffee machines are designed for precision but require regular maintenance and adjustments. Ensuring your machine is clean, well-calibrated, and functioning properly will help with extraction and overall flavor. A poorly maintained machine can lead to inconsistent shots, bitterness, or sourness.
Use Fresh Beans for a Better Flavor
One of the biggest mistakes baristas and coffee shops make is using old or stale beans. To improve the taste of your espresso, always use fresh beans. Coffee begins to lose its flavor shortly after roasting, so aim to use beans within two to four weeks of their roast date.
Additionally, consider the roast profile of your beans. Medium—to dark-roasted coffee often works best for espresso, as it provides a balanced flavor profile with the right amount of body and sweetness. Investing in high-quality grinders ensures a consistent ground coffee texture, which is crucial for even extraction.

Adjust the Grind Size for the Best Extraction
The right grind size is critical for pulling a good espresso shot. If your espresso tastes too bitter or sour, your grinder settings may need adjusting. A finer ground size slows extraction, enhancing sweetness and body, while a coarser grind speeds up extraction, potentially leading to a sour or weak shot.
A commercial burr grinder is essential for achieving consistent particle size. Make minor adjustments to your grinders and test each shot to find the optimal setting. Aim for an extraction time of around 25-30 seconds for a balanced shot. Adjust the grind size based on humidity and bean freshness when dialing in your espresso to maintain consistent quality.Â
Perfect the Espresso Ratio and Puck Preparation
The ratio of coffee to water is crucial for a well-balanced shot. Most commercial setups use a standard ratio of 1:2—this means if you dose 18 grams of coffee, you should yield about 36 grams of liquid espresso. Adjusting the ratio slightly can enhance flavor, depending on the beans you use.
Additionally, ensure that your puck is evenly distributed and properly tamped. Uneven tamping can lead to channeling, where water flows unevenly through the coffee, affecting the flavor. Use consistent, firm tamping pressure to create an even surface for the best-tasting results.

Use Filtered Water for a Cleaner Taste
Water quality significantly affects espresso taste. If you use unfiltered tap water, minerals and impurities can build up in your machines, affecting extraction and damaging them over time. Use filtered water to ensure a cleaner, crisper espresso taste, allowing the natural flavor of your coffee to shine.
Preheat Your Cups and Machine for Consistency
Temperature stability is crucial in making great espresso. If your cups are cold, they will immediately cool down the espresso, affecting the flavor and texture. Preheating your cups ensures that your espresso maintains its ideal tasting profile.
Similarly, warming up your machine before pulling a shot can help with extraction consistency. Running a few blank shots through the group head ensures everything is at the right temperature, preventing fluctuations that can impact flavor.
Keep Your Equipment in Top Condition
A well-maintained espresso machine and grinder make a huge difference in producing high-quality shots. Regular cleaning, descaling, and servicing ensure that your equipment functions optimally.
Backflush your machines daily.
Clean your burr grinder regularly to remove old-ground coffee
Replace seals and gaskets as needed
Ensure that your grinders are calibrated correctly
Keeping your equipment in top condition prevents off-flavors and guarantees a consistently great-tasting espresso.
Master the Milk for Perfectly Balanced Coffees
If your business serves milk-based coffees, mastering milk steaming is essential. Overheated milk can ruin the flavor of your drinks, while properly steamed milk enhances sweetness and texture. Heat fresh, cold milk to around 140°F (60°C) for the best results. Incorporating a smooth, velvety texture into your lattes and cappuccinos can elevate the overall tasting experience.
Honing Your Skills
Even with the right equipment and fresh beans, achieving the perfect espresso taste requires constant adjustments. Environmental factors like humidity and temperature can impact your coffee's behavior, so your grinders and espresso machine may need regular recalibration. Keeping a log of adjustments can help you track what works best for different beans and roasting profiles.Â
Common Mistakes That Ruin Espresso Taste
Avoiding these common mistakes can dramatically improve your espresso taste:
Using pre-ground coffee instead of grinding fresh
Neglecting to adjust the grind size based on extraction results
Ignoring water quality by not using filtered water
Skipping regular cleaning and maintenance of your espresso machine
Tamping too lightly or too hard, leading to uneven extraction
Forgetting to preheat cups, which can cool down espresso too quickly
Addressing these errors can help you create consistently excellent espresso shots that highlight the best flavor of your coffee.
