Are you tired of your espresso tasting weak and watery? Do you crave that bold, strong flavor that you can only find in a high-quality coffee shop? Well, you’re in luck! In this article, we will show you how to make a stronger espresso right at home using a commercial machine.
One of the most important factors in achieving a strong espresso is the quality of your coffee beans. Opt for beans that are specifically labeled as “espresso” or “dark roast.” These beans are typically roasted longer, resulting in a stronger flavor profile. Additionally, choose whole beans over pre-ground coffee to ensure freshness and maximum flavor extraction.
Once you have your high-quality coffee beans, it is crucial to grind them right before brewing. This ensures that the oils and flavors are preserved, resulting in a stronger and more aromatic espresso. Invest in a burr grinder, as it provides a consistent grind size. Aim for a fine to medium-coarse grind, as this allows for optimal extraction without over-extraction.
Next, make sure to use the right dose of coffee. The sweet spot is typically around 18-20 grams of coffee for a double shot of espresso. Using too little coffee will result in a weak and under-extracted espresso, while using too much coffee may cause over-extraction and a bitter taste. Adjust the dose according to your personal preference, but remember, less is not always more when it comes to making a strong espresso.
Now, let’s talk about the brewing process. It is essential to brew your espresso at the right temperature and under the right amount of pressure. Ideally, the water temperature should be around 195°F to 205°F (90°C to 96°C), as this allows for optimal extraction of flavors. Additionally, the pressure should be set between 9 and 10 bars, as this ensures proper espresso extraction without channeling or under-extraction.
Finally, don’t forget about the importance of proper tamping. Use a tamper to evenly distribute the coffee grounds in the portafilter and apply firm pressure. Tamping ensures that the water flows evenly through the coffee bed, resulting in a stronger and more balanced espresso shot.
By following these tips and techniques, you can make a stronger espresso on a commercial machine that rivals your favorite coffee shop. Experiment with different variables such as grind size, dose, and brewing time to find the perfect balance that suits your taste buds. With practice and patience, you’ll be sipping on a bold and flavorful espresso in no time!

- Origin: The region where the coffee beans are grown can also impact the flavor of your espresso. Different regions have different soil and climate conditions that can affect the taste of the beans. For example, beans from South America are known for their smooth and balanced flavor, while beans from Africa are often more fruity and floral.
- Blend or single origin: You can choose between using a blend of different coffee beans or a single origin bean. Blends are created by combining beans from different regions to create a unique flavor profile, while single origin beans come from a single farm or region and offer a more distinct flavor.
- Freshness: Freshly roasted coffee beans are essential for making a strong espresso. Aim to use beans that have been roasted within the past 2-4 weeks for the best flavor and aroma.
- Grind size: The grind size of the coffee beans is another important factor to consider. For espresso, a fine grind is usually recommended as it allows for a slower extraction and a stronger flavor.
Experimenting with different types of coffee beans can be a fun and exciting way to explore the world of espresso. By considering factors such as roast level, origin, blend or single origin, freshness, and grind size, you can find the perfect coffee beans to create a stronger and more flavorful espresso on your commercial machine.
Grinding the Beans to Perfection
One crucial step to making a stronger espresso on a commercial machine is grinding the beans to perfection. The quality of the grind can greatly affect the flavor and strength of your espresso.
When it comes to grinding coffee beans, consistency is key. A burr grinder is highly recommended for achieving the desired consistency. This type of grinder crushes the beans between two abrasive surfaces, resulting in a more uniform grind size.
The grind size plays a significant role in extraction. For a stronger espresso, a finer grind is typically recommended. This allows for a larger surface area of the coffee particles to come into contact with the water, resulting in a richer and more potent flavor.
Adjusting the Grind Size
Commercial espresso machines usually have built-in grinders, allowing for easy adjustment of the grind size. It’s important to experiment and find the right grind size that suits your preference.
If your espresso is tasting weak, try adjusting the grind size to a finer setting. On the other hand, if your espresso is too bitter or over-extracted, try a coarser grind. Remember to make small adjustments at a time and taste your espresso to find the optimal grind size.
Dosage and Distribution
In addition to the grind size, the dosage and distribution of coffee grounds also affect the strength of your espresso. Be sure to use the appropriate amount of coffee grounds and evenly distribute them in the portafilter.
Improper dosing or uneven distribution can result in an imbalanced extraction and weaker flavor. Invest in a quality coffee scale to measure the correct amount of coffee grounds for a consistent and strong espresso.
By carefully grinding your beans to perfection and ensuring proper dosage and distribution, you can make a stronger espresso on a commercial machine and enjoy a bold and flavorful cup of coffee every time.
Adjusting the Dosage and Tamping
To make a stronger espresso on a commercial machine, it is important to adjust the dosage of coffee grounds and the level of tamping. These two factors play a crucial role in determining the flavor and strength of the espresso shot.
Dosage: The dosage refers to the amount of coffee grounds used for a single shot of espresso. Increasing the dosage can result in a stronger and more flavorful espresso. Start by using the manufacturer’s recommended dosage and gradually increase it to find the desired strength. Experimenting with different dosages will help you understand how much coffee grounds are needed to achieve the desired flavor profile.
Tamping: Tamping is the process of evenly packing the coffee grounds into the portafilter to create a tightly packed puck. This step is crucial as it helps to maintain a consistent water flow during the brewing process. To make a stronger espresso, increase the pressure applied while tamping. Use a tamper to apply steady and even pressure to compress the coffee grounds firmly. However, be careful not to over-tamp, as this can result in channeling or uneven extraction.
By adjusting the dosage and tamping technique, you can create a stronger espresso with a richer flavor profile. Remember to experiment and fine-tune these variables to achieve the perfect balance and strength according to your preference.
Understanding the Brew Time and Pressure
When it comes to making a stronger espresso on a commercial machine, understanding the brew time and pressure is crucial. These two factors play a significant role in determining the strength and flavor profile of your espresso shot.
Brew Time
The brew time refers to the amount of time it takes for water to pass through the coffee grounds in the espresso machine. A shorter brew time typically results in a weaker espresso, while a longer brew time can produce a stronger and more concentrated shot.
To adjust the brew time, you can experiment with the grind size of your coffee beans. A finer grind will increase the surface area of the coffee, allowing water to extract more flavor and strength in a shorter amount of time. Conversely, a coarser grind will slow down the extraction process and result in a longer brew time.
It’s important to note that brew time should not be too short or too long. Too short of a brew time can lead to under-extraction, resulting in an espresso that lacks flavor and strength. On the other hand, too long of a brew time can lead to over-extraction, creating a bitter and unpleasant taste.
Pressure
Pressure is another critical factor in making a stronger espresso. Commercial machines are designed to deliver water at a specific pressure to ensure proper extraction. The typical pressure range for an espresso machine is between 9 and 10 bars.
If the pressure is too low, the water may not have enough force to extract the full flavor and strength from the coffee grounds. On the other hand, if the pressure is too high, it can lead to over-extraction and result in a bitter taste.
To ensure an optimal extraction, it’s essential to regularly check and adjust the pressure of your commercial machine. Most machines have built-in pressure gauges that display the current pressure level. If you notice that the pressure is consistently too low or too high, it might be necessary to calibrate or service your machine.
By understanding the brew time and pressure, you can achieve a stronger and more flavorful espresso on a commercial machine. Remember to experiment with different grind sizes and regularly monitor the pressure to fine-tune your brewing process and create the perfect cup of espresso every time.
