One feature that may seem simple but is deceptively tricky is using the single basket—the smaller filter basket for pulling a single shot. While the double basket is often the go-to for many espresso enthusiasts, the single basket presents a different challenge. If you're struggling to get the same rich and consistent results as you would with a double shot, you're not alone. However, with the right techniques and tools, you can master the art of pulling a perfect single shot of espresso. This guide will walk you through everything you need to know to take your single basket game to the next level, from understanding its quirks to troubleshooting common issues.

Understanding the Single Basket
When you first open your Breville or Sage espresso machine, you'll likely notice two different filter baskets in the portafilter: a single and a double basket. While the double basket often yields more consistent results, the single basket has its own unique characteristics that require a slightly different approach.

The Conical Design of the Single Basket
The key difference between the single and double basket is the design. The single basket has a conical shape that tapers toward the bottom. This design is meant to focus the water flow, but it can also create some challenges. For example, water can flow unevenly through the coffee puck, causing channeling (where water finds the path of least resistance, leading to uneven extraction) and inconsistent results. As a result, single shots may lack the depth and richness that double shots often achieve. Discover the key differences between these two models in our Breville Barista Pro vs Express review
Because of this, pulling a great single shot can be more delicate. You’ll need to adjust your technique to prevent issues like under-extraction (where the shot is weak and sour) or over-extraction (where the shot is bitter and harsh). Fortunately, with a bit of practice and the right tools, you can achieve great results with a single basket. Explore the advanced capabilities in our Breville Oracle vs Oracle Touch review
Essential Tools for Success
Before we dive into the specific steps for perfecting the single basket, let’s first take a look at some tools that will help ensure your success. Investing in high-quality tools will make the process easier and more enjoyable.
Coffee Scale: Precision is Key
Accurate measurements are critical for brewing the perfect espresso shot. A coffee scale helps you measure both the amount of coffee you’re using and the final output. This ensures that you’re using the right coffee-to-water ratio.
Highly Rated Option on Amazon:
Felicita Arc Espresso Scale – This scale is sleek, durable, and precise, making it an excellent choice for espresso enthusiasts. It’s highly rated and widely praised for its fast response and accurate measurements.
Burr Grinder: Consistency is Essential
A consistent grind is one of the most important factors in espresso brewing. A burr grinder provides the most uniform particle size, which is crucial for achieving consistent extraction. It’s tempting to use a blade grinder, but the uneven grind sizes can lead to inconsistent results.
Popular Choice:
Baratza Encore Conical Burr Grinder – This grinder is widely recommended by home baristas due to its consistent grind size, easy-to-use design, and affordable price point. It’s perfect for those just getting into espresso brewing.
Tamper: Even Compression Matters
A good tamper is essential for creating a level coffee puck. Uneven tamping can result in channeling, which ruins the shot. The tamper should feel solid in your hand and have a flat base to ensure even compression of the coffee grounds.
Recommendation:
Espro Calibrated Tamper – This tamper has a built-in calibration feature that ensures consistent tamping pressure every time. It’s a great investment for improving consistency in your espresso shots.
Steps to Perfecting the Single Basket
Now that you're equipped with the right tools, let’s go over the process for brewing a perfect single shot with your Breville or Sage espresso machine.
1. Adjust Your Coffee Dose
For a single shot, you’ll need around 9 to 10 grams of coffee, depending on your taste preferences and the specific basket you're using. It may seem tempting to just halve the dose used for a double shot, but you’ll find that you need slightly more than half of the usual double dose to get the right resistance for proper extraction.
2. Fine-Tune Your Grind Size
The conical design of the single basket requires a finer grind than the double basket. A coarser grind will cause the water to flow too quickly through the coffee, leading to under-extraction. Start by adjusting your grinder to a setting slightly finer than you would use for a double shot. This will slow down the water flow, allowing for a better extraction and richer flavor.
3. Purge Your Grinder
Switching between baskets or different coffee beans? Always purge a few grams of coffee from your grinder to avoid cross-contamination. This helps prevent flavor contamination between different grinds and ensures consistent results.
4. Use the 1:2 Brew Ratio
The ideal brew ratio for espresso is typically around 1:2—meaning for every gram of coffee you use, you should aim to get double the amount of liquid espresso. For a 10-gram dose, you should aim for about 20 grams of liquid espresso. This balance will help prevent under- or over-extraction, leading to a well-rounded and flavorful shot.
Troubleshooting Common Issues
Even with the best equipment and technique, you may still encounter some common espresso problems. Here are a few to watch out for and tips on how to solve them.
Problem: Watery or Sour Shots
If your shot tastes weak or sour, it's likely that your grind is too coarse. A coarse grind allows water to flow through the coffee too quickly, resulting in under-extraction.
Solution:
Make your grind finer to slow the flow of water. You may need to adjust the grind setting by a few notches until you find the right resistance.
Problem: Bitter or Overly Strong Shots
On the flip side, if your shot tastes bitter or overly strong, it’s a sign of over-extraction. This happens when the water spends too much time in contact with the coffee, pulling out too many bitter compounds.
Solution:
Reduce your dose slightly or try pulling a shorter shot. You can also experiment with slightly less coffee, such as 9 grams instead of 10.
Problem: Channeling (Uneven Extraction)
Channeling occurs when water finds a path of least resistance, often due to uneven tamping. It leads to uneven extraction and poor shot quality.
Solution:
Ensure your coffee puck is level before tamping, and use consistent pressure when tamping down. You may also benefit from using a distribution tool to spread the coffee grounds evenly in the portafilter before tamping.
Recommended Product:
Normcore WDT Tool for Espresso – This tool helps break up clumps in the coffee grounds and ensures a more even distribution, reducing the chances of channeling.
The Role of Pre-Infusion
Many Breville and Sage espresso machines come with a pre-infusion feature. This function applies a small amount of water to the coffee puck before full pressure is applied. Pre-infusion helps saturate the grounds evenly, reducing the likelihood of channeling and improving extraction, especially in a single basket.
If your machine has this feature, make sure to use it when brewing a single shot. It can make a significant difference in the quality of your shot.
Experimenting with Coffee Beans
The type of coffee beans you use can also affect the outcome of your single shot. Medium to dark roasts tend to work better in a single basket, as they have a more forgiving extraction profile and a richer, more chocolatey flavor. Lighter roasts, with their higher acidity, can be more challenging and may require extra attention to detail.
Popular Coffee Recommendations:
- Medium Roast: Lavazza Super Crema – Known for its smooth, mild flavor and balanced acidity, this is a great all-rounder for single shots.
- Dark Roast: Death Wish Coffee Co. Dark Roast – If you love a bold, full-bodied espresso with a rich flavor, this dark roast is a fantastic option.
Maintenance is Key
To keep your Breville or Sage espresso machine running smoothly and ensure the best possible shots, it's essential to perform regular maintenance.
Clean Equipment Regularly
After every shot, clean your portafilter and filter baskets to remove any residual coffee oils and grounds. These residues can affect the flavor of your espresso over time. Descaling your machine periodically is also important to prevent mineral buildup.
Replace Worn Accessories
Over time, parts like your tamper or portafilter basket may wear out. Regularly check for signs of wear and replace any accessories that have become less effective. High-quality replacement parts can help ensure consistent performance.
Advanced Techniques to Try
Once you've mastered the basics, you can experiment with more advanced techniques to refine your espresso brewing.
1. Temperature Surfing
Temperature stability is crucial in espresso brewing. Some advanced machines allow for slight temperature adjustments to fine-tune the extraction process. If your machine allows, experiment with small temperature adjustments to match the roast level of your coffee.
2. Milk-Based Drinks
Single shots work beautifully in milk-based drinks like lattes and cappuccinos. If you're a fan of these drinks, experiment with frothing milk to create a smooth, creamy microfoam. This will complement the subtle flavors of your single shot.
Recommended Milk Frother:
Breville Milk Cafe Frother – This frother can heat and froth milk to perfection, allowing you to create café-style lattes and cappuccinos at home.
3. Add-On Accessories
Consider investing in additional accessories like a bottomless portafilter or a dosing funnel to enhance your espresso experience.
Bottomless Portafilter:
Breville Bottomless Portafilter – This tool allows you to see the extraction process as it happens and can help you identify any issues with your tamping or distribution.
Why Stick with the Single Basket?
At first glance, the single basket might seem like a less versatile option than the double basket. However, there’s something uniquely rewarding about mastering the art of the single shot. A well-pulled single shot offers a clean, concentrated flavor that is perfect for those who enjoy lighter, more delicate coffee drinks. Plus, the challenge of refining your technique will help you become a more skilled barista overall.
