The Sage Dual Boiler Espresso Machine is a high-end coffee maker that guarantees perfect espresso shots every time. Many coffee enthusiasts, however, find it difficult to make a consistent and high-quality single shot with this machine. However, We’ll go over the factors that influence the quality of a single shot, as well as common issues that arise when shooting single shots with this machine and how to fix them. We’ll also share some additional tips to help you improve your single shot-making skills and make the most of your Sage Dual Boiler Espresso Machine.
The Trouble With Making Single Shots
Factors Affecting The Quality Of A Single Shot
- Grind Size: The grind size of your coffee beans is critical for producing a balanced shot. A fine grind results in over-extracted shots, whereas a coarse grind results in under-extracted shots. The ability to change the grind size gives you more control over the flavor and strength of the shot.
- Tamping Pressure: Tamping is the compression of coffee grounds in the portafilter. To ensure even extraction of the coffee, the proper amount of pressure is required. Oversampling can result in over-extracted shots, whereas undersampling can result in under-extracted shots.
- Water Temperature: For optimal extraction, the water temperature should be between 195°F and 205°F. Too hot water can result in burnt and bitter coffee, while too cold water can result in sour and weak coffee.
- Extraction Time: The extraction time is the amount of time it takes to extract coffee from the grounds. Longer extraction times can result in over-extracted shots, while shorter times can result in under-extracted shots.

- Inconsistent Shots: Uneven tamping or a poorly calibrated machine can cause inconsistent shots. Uneven tamping can result in uneven extraction, resulting in shots that taste different.
- Bitter Taste: Over-extraction, which can be caused by a fine grind, over-tamping, or hot water, can result in a bitter taste. Bitterness can also be caused by using stale or old coffee beans.
- Under-extracted Shots: Under-extracted shots can occur as a result of a coarse grind, inadequate tamping, or cold water. These shots have a sour or acidic flavor.
- Over-extracted Shots: Over-extracted shots can occur as a result of a fine grind, over-tamping, or hot water. These shots have a burnt or bitter flavor.
One of the primary issues encountered when making single shots with the Sage Dual Boiler is inconsistent extraction. Uneven tamping or a poorly calibrated machine can lead to uneven extraction, resulting in shots that taste different each time. To address this problem, it is crucial to ensure that the coffee grounds are evenly distributed and properly tamped.
Using a distribution tool or WDT (Weiss Distribution Technique) can help achieve a more uniform extraction. Additionally, calibrating the machine regularly and adjusting the grind size can also contribute to more consistent shots.
Another factor that can affect shot consistency is the quality and freshness of the coffee beans. Using freshly roasted beans and grinding them just before brewing can significantly improve the overall taste and consistency of the shots. It is recommended to experiment with different coffee beans and grind sizes to find the optimal combination that works best with the Sage Dual Boiler.
Another common issue reported by users is a bitter taste in their single shots. This can be attributed to over-extraction, which occurs when the coffee is extracted for too long or with excessive pressure. Over-extraction can be caused by a fine grind, over-tamping, or hot water temperature.
To avoid this, it is essential to ensure that the coffee grounds are not too fine and that the correct amount of pressure is applied during tamping. Adjusting the grind size and temperature settings on the machine can also help in achieving a balanced extraction.
Some users have also experienced difficulties in controlling the shot volume when making single shots with the Sage Dual Boiler. The shots may flow through too quickly, resulting in a larger volume than desired. This can be attributed to various factors, including the grind size, dose amount, and tamping pressure.
Adjusting these variables can help achieve the desired shot volume. It is recommended to start with a coarser grind size and gradually adjust it finer until the desired shot volume is achieved. Similarly, experimenting with different dose amounts and tamping pressures can also help in controlling the shot volume.
Proper calibration of the Sage Dual Boiler is crucial for achieving consistent results. Some users have reported difficulties in calibrating the machine to their desired specifications. It is recommended to refer to the user manual or seek assistance from the manufacturer’s customer support for guidance on machine calibration. Regular maintenance and cleaning of the machine, including descaling and backflushing, can also contribute to better performance and more consistent shots.
How To Fix The Trouble?
Adjusting the Grind Size:
Begin by grinding a small amount of coffee and pulling a shot to adjust the grind size. Adjust to a coarser grind if the shot is bitter or over-extracted. If the shot is sour or under-extracted, grind it finer. Continue adjusting the shot until it is balanced and smooth.
While tamping, use a level tamper and apply even pressure. The amount of pressure needed is determined by the type of coffee and the size of the portafilter. Applying 30 pounds of pressure is a good starting point. Remember that over- or under-tamping can result in inconsistent shots.
Adjusting the Water Temperature:
The water temperature on the Sage Dual Boiler Espresso Machine can be adjusted. Begin by heating the oven to the recommended temperature range of 195°F to 205°F. Reduce the temperature by a few degrees if the shot is too bitter. If the shot is too acidic, raise the temperature a few degrees.
Monitoring the Extraction Time:
A timer can be used to track the extraction time. As a general rule, aim for a shot that takes 25 to 30 seconds to pull. If the shot takes more than 30 seconds, the grind is probably too fine and the shot is over-extracted. If the shot takes less than 25 seconds, the grind is probably too coarse, and the shot is probably under-extracted.
Calibrating the Machine:
Calibrating the machine ensures that it is operating properly and consistently producing shots. To calibrate the machine, follow the manufacturer’s instructions. Adjusting the temperature and pressure settings is one example.
Using a Bottomless Portafilter:
With a bottomless portafilter, you can see the extraction and identify any flaws in the shot. It could be due to uneven tamping or a poorly calibrated machine if the extraction is uneven or spraying.
