Why Brew Temperature Matters in Espresso Making
Before diving into the process, it’s essential to understand the importance of brew temperature.
Temperature affects flavor extraction significantly. Water that’s too hot can lead to over-extraction, resulting in bitter or burnt flavors. Conversely, water that’s too cool can cause under-extraction, leaving your coffee sour or weak. The sweet spot for espresso brewing usually lies between 195°F and 205°F (90°C and 96°C), but slight adjustments can optimize the flavor for different beans.

- Light Roasts: These often shine at slightly higher temperatures, enhancing their bright, fruity notes.
- Dark Roasts: These benefit from lower temperatures, emphasizing their rich, chocolatey tones while avoiding bitterness.
Adjusting the temperature ensures you’re extracting the best flavors from any roast.
A Closer Look at the Breville/Sage Barista Express
The Breville/Sage Barista Express is a semi-automatic espresso machine designed for a balance of user-friendliness and control. It features a PID (Proportional-Integral-Derivative) controller that maintains consistent brewing temperatures. What many users don’t realize, however, is that the brew temperature can be manually adjusted for even greater customization.

Step-by-Step Guide to Adjust Brew Temperature
1. Power Off the Machine
Before making adjustments, ensure the machine is turned off. Press the power button to switch it off.
2. Enter Programming Mode
To access temperature settings, hold the ‘Program’ button while simultaneously pressing the ‘Power’ button. Continue holding the ‘Program’ button until the control panel lights flash, indicating that programming mode has been activated.
3. Adjust the Temperature
Once in programming mode, use the following buttons to modify the temperature:
- Single Shot Button: Decreases the temperature by 2°F (1°C).
- Double Shot Button: Increases the temperature by 2°F (1°C).
- Filter Size Button: Resets the temperature to the default 200°F (93°C).
LED indicators will display your current temperature setting:
- Both ‘1 Cup’ and ‘2 Cup’ lights on: Default temperature (200°F/93°C).
- ‘1 Cup’ light only: Lower temperature (198°F/92°C).
- ‘2 Cup’ light only: Higher temperature (202°F/94°C).
4. Fine-Tune Settings
Press the appropriate button until you achieve your desired setting. For instance:
- Use a slightly higher temperature for light roasts to accentuate their bright flavors.
- Opt for a slightly lower temperature with dark roasts to maintain sweetness and avoid bitterness.
5. Save Your Settings
To finalize, press the ‘Program’ button again. The machine will briefly power off and restart, saving the new temperature settings.
6. Test Your Espresso
Brew a shot and evaluate the flavor. If adjustments are needed, revisit the temperature or tweak other variables like grind size or tamping pressure. Achieving the perfect shot often requires some trial and error.
Troubleshooting and Pro Tips
