When I first began using my Breville (or Sage) espresso machine, I quickly discovered that making a flawless single espresso shot wasn’t just a matter of halving the coffee amount for a double shot. My machine came with two filter baskets: one for single shots and another for double shots. While pulling a double shot seemed simple enough, nailing the perfect single shot demanded more precision and experimentation.

Differences Between Single and Double Baskets
One of the first key distinctions I noticed was the unique design of the single basket compared to the double. The single basket has a tapered or conical shape, while the double basket features a flat bottom. This subtle difference has a significant impact on how water moves through the coffee grounds.

The narrower shape of the single basket often leads to uneven extraction, causing water to flow more rapidly through the center. This uneven flow tends to create channeling, which results in some parts of the coffee being under-extracted and others being over-extracted.

As a result, my single shots frequently lacked the balanced, full-bodied flavor I could achieve by simply splitting a double shot into two servings. Double shots consistently provided a richer and more enjoyable flavor profile. Discover the key differences between these two models in our Breville Barista Pro vs Express review
Techniques for Perfecting Single Shots
Determined to master the single basket, I experimented with several techniques. Over time, I discovered a few key adjustments that transformed the quality of my single shots. Explore the advanced capabilities in our Breville Oracle vs Oracle Touch review
Increase the Coffee Dose
One of the biggest breakthroughs was altering the coffee dose. Initially, I assumed that halving the double shot amount—approximately 18 grams—would do the trick. However, this produced weak and flat shots that brewed too quickly.
Increasing the dose to about 10 grams made a noticeable improvement in both extraction time and flavor. This adjustment provided greater depth and richness to my single shots, making them much more enjoyable
Adjust the Grind Size
Another critical factor was dialing in the grind size. Early attempts resulted in shots that brewed too quickly, indicating that my grind was too coarse. Adjusting my grinder to a finer setting significantly improved both the timing and flavor of my shots.
Finer grinds slow down the flow of water, allowing for more even extraction. This simple tweak played an essential role in achieving a more balanced and flavorful espresso.
Use a Scale and Maintain a 1:2 Brew Ratio
Precision was vital, and using a scale proved crucial for consistent results. I adhered to a 1:2 brew ratio: for every gram of ground coffee, I aimed to pull twice the weight in liquid espresso. With 10 grams of coffee, my target was 20 grams of espresso.
This approach ensured that my single shots were neither weak nor diluted, consistently delivering a well-balanced and concentrated espresso.
Don’t Overlook the Grinder Purge
Switching between single and double baskets requires some extra attention with your grinder. After adjusting the grind size for a single shot, I made sure to purge any leftover grounds to maintain shot consistency.
This step is especially important if you frequently alternate between the two baskets. Leftover grounds can disrupt the grind size and negatively impact the flavor balance of your shot.
Overcoming Challenges and Enjoying the Rewards
While using the single basket initially proved more challenging than the double, it became a rewarding experience once I perfected my technique. It demanded patience and precision, but the outcome was a clean, concentrated shot that worked wonderfully in milk-based drinks like lattes and cappuccinos.
For those who prefer a lighter, more delicate espresso flavor or need just a single shot for milk drinks, experimenting with these adjustments is definitely worthwhile. Every machine and palate is different, so keep tweaking grind sizes, doses, and extraction times until you find your perfect balance.
Conclusion
Mastering the single basket with a Breville or Sage espresso machine may feel daunting at first due to its conical design and the precise adjustments it demands. However, persistence and experimentation will eventually reward you with a beautifully balanced single shot.
Perfecting the single basket not only improved my espresso skills but also deepened my appreciation for the art of brewing. I encourage you to experiment—embrace the challenge and discover the satisfaction that comes with pulling a flawless single shot.
