3. Brewing the Perfect Espresso

Step 1: Selecting Quality Beans

For an exceptional espresso, start with high-quality, freshly roasted beans. Bazan Coffee offers specialty beans sourced from Vietnam's renowned coffee regions, ensuring rich and diverse flavor profiles.

Step 2: Grinding and Dosing

  • Grind Size: Aim for a fine grind, resembling table salt. Adjust your grinder accordingly to achieve this consistency.

  • Dosing: Use 18-20 grams of coffee grounds for a double shot. This dosage aligns with standard espresso recipes and ensures a balanced extraction.

Step 3: Tamping

  • Portafilter Size: The Breville Bambino features a 54mm portafilter.

  • Tamper Size: For optimal results, use a 53mm tamper, which fits snugly within the 54mm portafilter, ensuring even pressure distribution.

  • Technique: Distribute the coffee grounds evenly in the portafilter and apply firm, level pressure with the tamper to create a uniform coffee bed.

Step 4: Extraction

  1. Pre-Infusion: The Bambino applies low-pressure water to the coffee puck, allowing it to expand gently.

  2. Extraction: Following pre-infusion, water pressure increases to extract the espresso over approximately 25-30 seconds.

Step 5: Milk Texturing

  1. Fill the Milk Jug: Pour cold milk into the jug up to the appropriate indicator line.

  2. Manual Texturing: Position the steam wand just below the surface of the milk and open the steam valve. Adjust the position to create a whirlpool effect, resulting in silky microfoam ideal for latte art.

4. Cleaning and Maintenance

Regular maintenance ensures the longevity and performance of your machine.

Daily Cleaning

  • Purge the Steam Wand: After each use, wipe the wand with a damp cloth and initiate a steam purge to clear any milk residue.

  • Empty the Drip Tray: Regularly remove and clean the drip tray to prevent overflow and maintain hygiene.

Weekly Cleaning

  • Group Head Cleaning: Insert the provided cleaning disc and tablet into the portafilter, attach it to the group head, and initiate the cleaning cycle as per the machine's instructions.

Monthly Maintenance

  • Descaling: Mineral deposits can accumulate over time, affecting performance. To descale:

    1. Fill the water tank with a descaling solution as per the manufacturer's instructions.

    2. Press the 1 CUP and STEAM buttons simultaneously for 5 seconds to start the descaling process.

    3. Follow the on-screen prompts to complete the cycle.

Q3: How do I change the filter basket on the Breville Bambino?

A: Over time, you may need to switch between single-wall and dual-wall filter baskets depending on your coffee grind size or replace them if worn out. Follow these steps to change the filter basket:

  1. Remove the Portafilter – Unlock the portafilter from the machine.

  2. Eject the Old Filter Basket – Insert your fingers or use a small tool (like a butter knife) to gently pop out the basket.

  3. Insert the New Filter Basket – Align the new basket inside the portafilter and press it firmly into place.

  4. Test Fit – Ensure it sits flush and secure before reattaching it to the machine.

✔ Pro Tip: Use single-wall baskets for fresh ground coffee and a separate grinder, and dual-wall baskets if using pre-ground coffee for added pressure control.

Q4: What size portafilter does the Breville Bambino use?

A: The Breville Bambino uses a 54mm portafilter, which is smaller than the standard 58mm portafilters found on commercial machines.

Q5: What size tamper should I use with the Breville Bambino?

A: The ideal tamper size for the Breville Bambino is 53mm, which fits snugly inside the 54mm portafilter for even and consistent tamping. Using the correct size tamper ensures proper compression of coffee grounds, leading to better extraction.

Q6: How do I dial in the Breville Bambino for the best espresso shot?

Dialing in your Breville Bambino Espresso Machine means fine-tuning grind size, dose, and extraction time to achieve the perfect balance of flavors. Follow these steps:

  1. Set the Grind Size – Start with a fine grind (similar to table salt). If extraction is too fast, go finer; if too slow, go coarser.

  2. Weigh the Dose – Use 18-20g of coffee for a double shot.

  3. Tamp Evenly – Apply firm, level pressure using a 53mm tamper.

  4. Extract the Espresso – The total shot time should be between 25-30 seconds. If it’s shorter, use a finer grind; if longer, use a coarser grind.

✔ Pro Tip: Taste your espresso—if it’s sour, under-extracted, go finer. If it’s bitter, over-extracted, go coarser.

5. Frequently Asked Questions (FAQs)

Q7: How do I turn off the Breville Bambino?

A: The Bambino enters standby mode automatically after a few minutes of inactivity. However, to manually turn it off:

✔ Pro Tip: Unplug the machine if you won’t be using it for extended periods.

Q8: How do I clean the Breville Bambino steam wand?

A: The steam wand should be cleaned after every use to prevent milk buildup and clogging. Follow these steps:

  1. Wipe Immediately – Use a damp cloth to clean the exterior right after steaming.

  2. Purge Steam – Point the wand into the drip tray and release steam for 3-5 seconds.

  3. Deep Clean Weekly – If clogged, soak the steam tip in hot water and white vinegar for 30 minutes, then use a cleaning pin to remove any milk residue.

✔ Pro Tip: Never let milk dry on the steam wand—it becomes difficult to remove and affects performance.

Q9: How do I descale the Breville Bambino?

A: Descaling removes mineral buildup from water inside your machine, improving longevity and temperature stability.

  1. Prepare the Machine – Remove the water filter from the tank.

  2. Mix the Descaling Solution – Use Breville’s official descaler or a 50/50 vinegar-water mix and pour it into the water tank.

  3. Start Descaling Mode –

    • Press and hold the 1 CUP and STEAM buttons for 5 seconds.

    • Release when the lights start flashing.

  4. Run the Cycle – Follow the on-screen prompts. The process takes about 5-10 minutes.

  5. Flush the System – Refill the tank with clean water and run another cycle to rinse out any remaining descaling solution.

✔ Pro Tip: If using hard water, descale every 2-3 months; otherwise, every 3-6 months is sufficient.

Q10: How do I reset the Breville Bambino to factory settings?

6. Troubleshooting Common Issues with the Breville Bambino

Even with proper use, occasional issues may arise with your Breville Bambino Espresso Machine. Here are some solutions to common problems:

Issue 1: The machine won’t turn off

✔ Solution: The Bambino enters standby mode automatically after a period of inactivity. However, if you need to turn it off manually, press and hold the 1 CUP and STEAM buttons simultaneously until the machine powers down.

Issue 2: The espresso is weak or under-extracted

✔ Solution:

  • Ensure you are using freshly ground coffee beans (pre-ground coffee loses its freshness quickly).

  • Use a finer grind size to slow down extraction time.

  • Increase the coffee dose to 18-20g for a double shot.

  • Check that your tamping pressure is firm and even.

Issue 3: The espresso is too bitter or over-extracted

✔ Solution:

  • Use a coarser grind size to speed up extraction.

  • Reduce the coffee dose slightly if needed.

  • Check the extraction time – it should be 25-30 seconds.

Issue 4: Steam wand is clogged or not frothing milk properly

✔ Solution:

  • After each use, purge the wand by releasing steam for 3-5 seconds to remove milk residue.

  • If the wand is clogged, soak the tip in hot water and white vinegar for 30 minutes, then use a pin to unclog it.

Issue 5: How to reset the Breville Bambino to factory settings?

✔ Solution:

  1. Ensure the machine is turned off.
