Understanding The Importance Of Pressure In Making Espresso
To fully appreciate the significance of pressure, we must first understand its role in the espresso-making process. Pressure is what allows hot water to extract the flavors and aromas from coffee grounds, producing the rich and intense espresso that we all crave.
During the brewing process, water is forced under pressure through tightly packed coffee grounds, extracting the soluble compounds that give espresso its unique taste profile. The ideal pressure range for espresso extraction is typically between 8 and 9 bar (116-130 psi). At this pressure, the water can penetrate the coffee bed evenly and efficiently, resulting in a balanced extraction.
If the pressure is too low, the water will pass through the coffee grounds too quickly, resulting in under-extracted espresso shots. These shots can have a weak and sour taste, lacking the intensity and depth of flavor that characterizes a well-made espresso.
Conversely, if the pressure is too high, the water will struggle to pass through the compacted coffee bed, leading to over-extraction. Over-extracted espresso shots can taste bitter and burnt, with an unpleasant aftertaste that lingers on the palate.
Achieving optimal pressure is crucial for producing a well-balanced and flavorful espresso shot. Luckily, if you are experiencing pressure issues with your Breville espresso machine, there are several troubleshooting steps you can take to rectify the problem.

This allows the machine’s internal components to reach the optimal temperature and ensures a stable and consistent pressure throughout the extraction.
2. Use Freshly Roasted Coffee Beans
Using fresh and high-quality coffee beans is crucial for achieving optimal pressure and flavor. Coffee beans start to lose their freshness and aromatic compounds shortly after being roasted. Stale beans can have a negative impact on pressure, resulting in under-extraction and lackluster espresso shots. Purchase freshly roasted beans from reputable sources and store them properly to maintain their freshness.
3. Adjust Grind Size
Grind size plays a significant role in pressure and extraction. If your Breville espresso machine is consistently producing under-extracted shots with low pressure, try adjusting the grind size slightly finer. A finer grind will slow down the flow of water, allowing for better extraction and increased pressure.
Conversely, if you are experiencing over-extraction and high pressure, try adjusting the grind size slightly coarser. A coarser grind will allow the water to flow more freely through the coffee bed, resulting in a faster extraction and reduced pressure.
Make small adjustments to the grind size and observe how it affects the pressure and taste of your espresso shots. Keep in mind that different coffee beans and blends may require slight variations in grind size to achieve optimal results.
4. Perfect Your Tamping Technique
Tamping is the process of firmly compacting the coffee grounds in the portafilter before extraction. Proper tamping ensures an even and consistent extraction, maximizing pressure and flavor. Here are some tips to improve your tamping technique:

- Apply even pressure: When tamping, apply even pressure to the entire surface of the coffee bed. Avoid applying excessive force, as this can create uneven puck density and lead to channeling, which disrupts the extraction and affects pressure.
- Level the coffee bed: Before tamping, ensure that the coffee grounds in the portafilter are level and evenly distributed. Use a finger or a distributing tool to distribute the grounds evenly and remove any air pockets.
Experiment with different tamping techniques and find the one that works best for you. Consistency and precision are key to achieving optimal pressure and extraction.
5. Experiment With Brew Ratio
The brew ratio refers to the ratio of coffee to water used during the brewing process. Adjusting the brew ratio can have a significant impact on pressure and flavor. A higher coffee-to-water ratio will increase the resistance for the water, resulting in higher pressure and a more intense espresso shot.
Start with a standard brew ratio of 1:2 (18 grams of coffee to 36 grams of water) and experiment from there. Increase the coffee dose while keeping the water volume constant to achieve a stronger and more full-bodied espresso. Keep a record of your preferred brew ratios and adjust accordingly to achieve your desired pressure and flavor profile.

On the other hand, if the grind size is too coarse, the water will flow too quickly through the coffee bed, resulting in low pressure and under-extracted espresso that tastes weak and sour.
To find the optimal grind size, start with a medium grind setting and make small adjustments from there. Monitor the pressure gauge and observe the rate of extraction. If the pressure is too high, indicating a slow flow, adjust the grind size slightly coarser. If the pressure is too low, indicating a fast flow, adjust the grind size slightly finer.
Keep in mind that the ideal grind size can vary depending on the specific coffee beans you are using, as well as personal preference. Experiment and make incremental changes until you find the grind size that consistently produces the desired pressure and flavor.
Tamping Technique
Tamping is the process of evenly compressing the coffee grounds in the portafilter to create a uniform surface for water to pass through during extraction. Proper tamping technique is crucial for achieving high pressure and even extraction.
When tamping, it’s important to apply firm and even pressure to the coffee bed. Inconsistent tamping pressure can lead to uneven extraction and fluctuations in pressure. Here are some tips for improving your tamping technique:
- Use a calibrated tamper: A calibrated tamper ensures that you are applying a consistent level of pressure every time. This eliminates the guesswork and helps achieve a uniform tamp.
- Apply even pressure: When tamping, distribute pressure evenly across the entire surface of the coffee bed. Avoid applying excessive force, as this can lead to uneven puck density and affect pressure and extraction.
- Level the coffee bed: Before tamping, ensure that the coffee grounds in the portafilter are level and evenly distributed. Use a finger or a distributing tool to distribute the grounds evenly and remove any air pockets.
The key to achieving optimal pressure and extraction through tamping is consistency. Practice your tamping technique and strive for uniformity in pressure, evenness in distribution, and levelness in the coffee bed.
