If you’re passionate about espresso, you know that creating the perfect shot goes beyond just grinding the right beans or using the right amount of pressure. It’s an intricate balance of many factors, and one of the most important—but often overlooked—variables is brew temperature. Whether you're crafting a single-origin light roast or indulging in a rich, dark blend, the right brew temperature can elevate your espresso to a whole new level.

For home baristas using the Breville or Sage Barista Express (the same machine, depending on your region), you have more control over this aspect than you might think. The Barista Express features a PID (Proportional-Integral-Derivative) controller that maintains stable temperatures, but it also allows for manual adjustments to customize your brew temperature. Understanding how to tweak the brew temperature can unlock the full potential of your coffee beans, especially when you’re trying to dial in the perfect shot.

In this guide, we’ll walk you through how to adjust the brew temperature on your Breville/Sage Barista Express, explain why this matters for your espresso, and offer tips on how to make the most of your machine. Compare these two top models in our Breville Barista Express Impress vs Pro review

Why Brew Temperature Matters

Before diving into how to adjust the brew temperature, let’s quickly review why it’s such a critical factor. The brew temperature directly impacts the flavor extraction process. If the water is too hot, it can over-extract the coffee, leading to bitter, burnt flavors. On the other hand, water that’s too cool won’t extract enough, resulting in a sour, weak shot.

• Hotter Water (200°F–205°F or 93°C–96°C): Ideal for light roasts, as it helps to extract the more delicate, bright, and fruity flavors.
• Cooler Water (195°F–200°F or 90°C–93°C): Better for darker roasts, as it prevents over-extraction, which can amplify bitterness and mask the roast’s inherent sweetness.

Your Breville/Sage Barista Express is equipped with a PID controller that helps stabilize water temperature during brewing. This ensures a more consistent shot than older, less sophisticated espresso machines. However, tweaking the temperature can help you customize your shot to match the specific beans you’re using or adjust for your personal taste preferences.

Step-by-Step: Adjusting Brew Temperature

Ready to change the brew temperature on your Breville/Sage Barista Express? Let’s go through the steps.

1. Turn Off the Machine

Before you start, make sure to turn off the machine to ensure you’re starting fresh. This prevents any unwanted interference with your settings and ensures a clean slate when you enter programming mode.

2. Enter Programming Mode

Now that the machine is off, you’ll need to enter programming mode to make the necessary adjustments to the brew temperature. Follow these steps:

• Press and hold the ‘Program’ button.
• While holding the Program button, press the Power button to turn the machine back on.
• Continue holding the Program button until the lights on the control panel start flashing.

Once the lights flash, you've successfully entered programming mode.

3. Choose Your Desired Temperature

Now that you’re in programming mode, it's time to adjust the brew temperature. You can adjust it up or down in small increments. Here’s how:

• Single Shot Button: Lowers the temperature by 2°F (about 1°C).
• Double Shot Button: Raises the temperature by 2°F (about 1°C).
• Filter Size Button: Resets the temperature to the default setting (200°F or 93°C).

The LED indicators on the control panel will show the current temperature setting. Here’s how to interpret them:

• Both the Single and Double Shot lights: The temperature is set to the default of 200°F (93°C).
• Only the Single Shot light: The temperature is set to 198°F (92°C), lowered by 2°F.
• Only the Double Shot light: The temperature is set to 202°F (94°C), raised by 2°F.

4. Adjust According to Taste

Depending on the roast of your coffee beans, you may want to experiment with the temperature:

• For Light Roasts: Increase the temperature to around 202°F (94°C) to help extract the vibrant acidity and fruity notes.
• For Medium Roasts: Stick with the default temperature of 200°F (93°C) for a balanced shot.
• For Dark Roasts: Lower the temperature to around 198°F (92°C) to avoid over-extracting the bitter compounds.

5. Save the Setting

Once you’ve dialed in the perfect temperature for your beans, save your settings. To do this, simply press the Program button again. The machine will briefly turn off and restart with your new temperature settings in place.

Testing and Fine-Tuning Your Brew Temperature

After adjusting the temperature, you’ll want to pull a test shot and see how it tastes. The goal is to dial in a shot that has balanced flavors and a pleasant mouthfeel. Here are a few things to observe when testing:

• Flavor Profile: Does the shot taste well-balanced? If it’s too sour, the temperature may be too low, and if it’s too bitter, it may be too high.
• Extraction Time: For a double shot, aim for an extraction time of about 25-30 seconds. If the shot pulls too quickly or too slowly, you may need to adjust the grind size or tamping pressure in addition to the brew temperature.
• Crema Quality: A rich, golden crema indicates a well-extracted shot. If the crema is pale or disappears quickly, the extraction may not be optimal.

As you fine-tune the brew temperature, consider adjusting other variables like grind size or tamping pressure to perfect the shot. Temperature, grind, and pressure all work together in the extraction process.

Why You Should Adjust Brew Temperature

Your coffee beans play a massive role in determining the ideal brewing temperature. Different beans react differently to heat, and adjusting the temperature accordingly can significantly improve your espresso.

• Light Roasts: Light roasts are denser and can be more challenging to extract fully. Higher temperatures (around 202°F or 94°C) help to unlock the complex, bright flavors typically found in these beans.
• Medium Roasts: Medium roasts are more versatile and tend to extract well at around 200°F (93°C), making this the default temperature for most home baristas.
• Dark Roasts: Dark roasts are more delicate and susceptible to bitterness. Lowering the temperature to around 198°F (92°C) helps preserve the natural sweetness and prevent over-extraction.

Troubleshooting Common Issues

Even with a perfectly adjusted brew temperature, you might encounter a few issues. Here’s how to troubleshoot:

Espresso Tastes Sour

• Cause: Under-extraction due to too low a brew temperature.
• Solution: Increase the temperature by 2°F (1°C) and test again.

Espresso Tastes Bitter

• Cause: Over-extraction caused by too high a brew temperature.
• Solution: Decrease the temperature by 2°F (1°C) and reassess.

Temperature Changes Don’t Register

• Cause: You might not be in programming mode when making adjustments.
• Solution: Ensure that the control panel lights are flashing, which means you're in the correct mode. If this doesn’t resolve the issue, consult the machine’s manual or reach out to Breville/Sage customer support for further assistance.
