Step-by-Step Guide To Calibrating Your Barista Express
Now that you have gathered all the necessary tools and materials, let’s dive into the step-by-step process of calibrating your Breville Barista Express:
Step 1: Clean And Prepare
Before starting the calibration process, it’s important to clean and prepare the machine. Begin by flushing water through the group head to remove any coffee residue or oils. This can be done by running a blank shot through the machine without any coffee grounds.
Next, ensure that the portafilter is clean and free from any old coffee grounds. This will prevent any leftover flavors from tainting your freshly brewed espresso. Rinse the portafilter with warm water and thoroughly dry it.
Step 2: Set The Grind Size
The grind size is one of the key factors that determine the extraction of flavors from the coffee beans. It’s crucial to find the right grind size that suits your particular coffee beans and desired brew method. As a starting point, set the grind size to a medium level.
To adjust the grind size on the Barista Express, locate the grind size dial on the side of the machine. Rotate the dial to the desired setting, keeping in mind that finer grind settings will result in a slower extraction, while coarser settings will produce a faster extraction.
Step 3: Determine The Dose Amount
The dose amount refers to the amount of coffee grounds used for each shot. It plays a significant role in achieving the desired strength and flavor profile of your espresso. Start by using a dose amount of around 18-20 grams, as this is a common range for achieving a balanced brew ratio.
To measure the dose accurately, use the scale to weigh your coffee beans before grinding them. Adjust the grinder settings if needed to achieve the desired dose amount.
Step 4: Distribute And Tamp
Once you have your desired dose amount, it’s time to distribute and tamp the coffee grounds in the portafilter. Proper distribution helps ensure an even extraction, while tamping provides consistent resistance for the water during extraction.
To distribute the coffee grounds evenly, gently tap the sides of the portafilter with your palm or a tamp. This will settle the coffee grounds and eliminate any air pockets.
Next, place the portafilter on a stable surface and use the tamper to apply consistent downward pressure. The coffee grounds should be evenly compressed, but not too tightly. A firm and level tamp is key to achieving a balanced extraction.
Step 5: Extract The Espresso Shot
Now that your portafilter is loaded and properly tamped, it’s time to extract the espresso shot. Place the portafilter into the group head and initiate the extraction process. Pay close attention to the extraction time and the resulting espresso volume.
For a standard double shot, a typical extraction time is around 25-30 seconds. If the extraction is too fast, resulting in a watery shot, try adjusting the grind size to make it finer. Conversely, if the extraction is too slow or chokes the machine, making the shot bitter, adjust the grind size to be coarser.
Step 6: Taste And Evaluate
Once the shot is extracted, it’s time to taste and evaluate the espresso. Use your senses to assess the flavor, aroma, and overall quality of the shot. Look for attributes such as sweetness, acidity, body, and balance.
If you’re satisfied with the shot, you can proceed with making more shots using the same parameters. However, if adjustments are needed, take note of the extraction time, flavor profile, and any issues you encountered. This information will guide you in fine-tuning your calibration process.
Step 7: Repeat And Experiment
Calibration is an iterative process, and it’s common to make several adjustments before finding the perfect espresso shot. Repeat the extraction process, making small changes to the grind size, dose amount, or extraction time until you achieve your desired flavor profile.
Remember to take note of all the changes you make and their impact on the resulting shot. This will help you to understand how different variables interact and how they affect the final cup of espresso.
Troubleshooting Common Calibration Issues
During the calibration process, you may encounter common issues that affect the extraction quality. Here are some troubleshooting tips for addressing these issues:
-
Extraction too fast: If the extraction is too fast, resulting in a weak and watery shot, try adjusting the grind size to make it finer. This will slow down the extraction and allow for better flavor extraction.
-
Extraction too slow or choked: When the extraction is too slow, resulting in a bitter and over-extracted shot, adjust the grind size to be coarser. This will speed up the extraction and prevent the machine from being choked.
-
Channeling: Channeling refers to uneven water flow during extraction, leading to an imbalanced shot. Ensure that the coffee grounds are evenly distributed and that the tamp is level and consistent to minimize channeling.
-
Bitterness or sourness: Bitterness can be caused by over-extraction, while sourness can be a result of under-extraction. Adjust the extraction time and grind size to achieve a balanced shot with a pleasant flavor profile.
-
Uneven extraction: If you notice uneven extraction, where certain areas of the coffee puck extract more than others, the distribution and/or tamping technique may be inconsistent. Focus on maintaining a level tamp and experimenting with distribution techniques.
Remember that calibration is a dynamic process, and minor adjustments may be needed as factors such as humidity, coffee bean freshness, and roast level change over time.
