If you're a coffee enthusiast, you've likely dreamed of perfecting the art of espresso at home. The Breville or Sage espresso machine is a popular choice for aspiring baristas, offering a versatile and user-friendly platform to hone your skills. However, using the single basket for a single shot can be a surprisingly tricky endeavor. Whether you're new to home espresso or refining your technique, understanding the quirks of the single basket can transform your espresso experience. Here’s how to master it. Get a detailed look at the precision and features in our Breville Dual Boiler BES920XL review
Understanding the Single Basket
When you first unbox your Breville or Sage espresso machine, you'll notice two filter baskets in the portafilter: a single and a double. While the double basket often yields consistently excellent results, the single basket’s unique conical design presents some challenges. Learn about the sleek design and functionality in our Breville Barista Touch Impress review
The Conical Difference
Unlike the double basket, the single basket tapers at the bottom. This shape focuses water flow but can create uneven pressure and channeling, leading to under- or over-extracted coffee. As a result, single shots can lack the depth and richness of their double-shot counterparts unless you adjust your technique.

Tools for Success
Before diving into the nuances of brewing, make sure you have the right tools to set yourself up for success:
- Coffee Scale: Essential for accurate measurements of both coffee grounds and shot output.
- Highly Rated Option on Amazon: Felicita Arc Espresso Scale.
- Burr Grinder: A high-quality burr grinder ensures consistent grind size, a critical factor for single shots.
- Popular Choice: Baratza Encore Conical Burr Grinder.
- Tamper: A proper tamper helps create a level coffee puck, reducing the chances of channeling.
- Recommendation: Espro Calibrated Tamper.
Steps to Perfecting the Single Basket
1. Adjust Your Coffee Dose
For a single shot, aim for about 10 grams of coffee. The single basket’s smaller capacity means you can’t simply halve the dose used for a double shot. A slightly higher dose than expected for a single (e.g., 10 grams instead of 9) provides better resistance and fuller flavor.

2. Fine-Tune Your Grind Size
The single basket's conical shape requires a finer grind than the double basket. Start by adjusting your grinder to a setting slightly finer than what you use for a double shot. This slows water flow and ensures proper extraction. Explore the advanced capabilities in our Breville Oracle vs Oracle Touch review
3. Purge Your Grinder
Switching from double to single shots? Purge a few grams of coffee from your grinder to avoid cross-contamination of grind sizes. Inconsistent grind sizes can disrupt water flow and affect flavor.
4. Use the 1:2 Brew Ratio
Weigh your coffee input (10 grams) and aim for an output of about 20 grams of liquid espresso. This 1:2 brew ratio strikes a balance between under- and over-extraction, resulting in a well-rounded shot.
Troubleshooting Common Issues
Problem: Watery or Sour Shots
Solution: Your grind is likely too coarse. Finer grounds will slow the water flow, increasing contact time and extraction.
Problem: Bitter or Overly Strong Shots
Solution: This indicates over-extraction. Try reducing the dose slightly or pulling a shorter shot (e.g., 1:1.5 ratio).
Problem: Channeling (Uneven Extraction)
Solution: Ensure your puck is level before tamping, and apply consistent pressure with your tamper. You may also benefit from tools like a distribution tool to evenly spread the grounds.

The Role of Pre-Infusion
Many Breville or Sage machines offer pre-infusion, a process where a small amount of water saturates the coffee puck before full pressure is applied. This feature is particularly useful for the single basket, helping to mitigate channeling and ensure a more even extraction.
Experiment with Coffee Beans
Medium to dark roasts often work best in the single basket due to their forgiving nature and rich, chocolatey flavor profiles. Light roasts, with their higher acidity, require meticulous technique and may not be ideal for beginners.
Popular Coffee Recommendations:
- Medium Roast: Lavazza Super Crema
- Dark Roast: Death Wish Coffee Co. Dark Roast
Maintenance is Key
Clean Equipment Regularly
Residual coffee oils and grounds can interfere with your espresso’s flavor. Clean your basket and portafilter after each use, and descale your machine periodically.
Replace Worn Accessories
Over time, your machine’s accessories, like the tamper or portafilter basket, may wear out. Investing in high-quality replacements ensures consistent results.
Advanced Techniques to Try
1. Temperature Surfing
Temperature stability is crucial for espresso extraction. If your machine allows, experiment with slight temperature adjustments to suit your beans and grind size.
2. Milk-Based Drinks
The subtle flavor of a single shot shines in milk-based drinks like lattes and cappuccinos. Froth your milk to a creamy microfoam for the perfect complement.
- Recommended Milk Frother: Breville Milk Cafe Frother.
3. Add-On Accessories
Accessories like bottomless portafilters and dosing funnels can help refine your technique.
- Bottomless Portafilter: Breville Bottomless Portafilter.
Why Stick with the Single Basket?
The single basket might feel like a finicky tool at first, but it offers unique rewards. A well-pulled single shot is clean, concentrated, and perfectly suited to those who prefer lighter coffee drinks. Additionally, the challenge of mastering it sharpens your barista skills, helping you better understand the nuances of extraction.
Final Thoughts
Brewing espresso is both an art and a science, and the single basket is a testament to this. While it requires patience and precision, the journey of mastering it is incredibly rewarding. By tweaking your dose, grind size, and brew ratio—and equipping yourself with the right tools—you can transform your single shots into barista-quality espresso.
So, embrace the challenge, experiment freely, and savor every shot. After all, the perfect espresso isn’t just about the result; it’s about the joy of the process. Happy brewing!
