When I first unboxed my Breville (or Sage) espresso machine, I was excited to create barista-level espresso from the comfort of my kitchen. After countless hours of researching, watching tutorials, and reading articles, I felt ready to brew that elusive perfect shot. However, I soon discovered that pulling a single shot wasn’t as simple as halving a double shot recipe. The process turned out to be more intricate and required a deeper understanding.
The espresso machine came with two filter baskets: one for single shots and another for double shots. While double shots were a breeze to perfect, my initial attempts with the single basket fell flat. The flavor lacked consistency, the volume varied, and the extraction often seemed off. Through trial and error, I learned that mastering the single basket required a unique approach. Here's how I did it.

Understanding Single vs. Double Baskets
One key distinction between the single and double baskets lies in their design. The double basket has a flat bottom, while the single basket features a conical or tapered shape. This subtle difference drastically impacts water flow and extraction. Learn about the sleek design and functionality in our Breville Barista Touch Impress review
The conical shape of the single basket tends to promote uneven water distribution, increasing the risk of channeling. Channeling occurs when water flows faster through some areas of the coffee puck than others, resulting in uneven extraction. This can cause bitterness from over-extraction in some parts and sourness from under-extraction in others, leading to an unbalanced espresso shot.

Double shots, in contrast, generally yield richer and more consistent flavors. However, I was determined to master the single basket. With persistence, I uncovered techniques to improve my results. Discover the key differences between these two models in our Breville Barista Pro vs Express review
Refining Your Single Basket Technique
Adjust the Coffee Dose
My first realization was that the dose needed adjustment. Initially, I tried using half the coffee required for a double shot (around 9 grams), but this often resulted in weak, watery shots. Increasing the dose to 10 grams provided the resistance needed for better extraction, leading to a fuller, more balanced flavor.

Fine-Tune the Grind Size
Another critical factor was the grind size. My initial attempts with a coarser grind resulted in rapid extractions, which lacked depth. Adjusting the grind to be finer than what I used for double shots slowed the flow rate, delivering a more even extraction and eliminating sourness.
Use a Scale and Aim for a 1:2 Brew Ratio
Consistency became achievable once I started using a scale. Minor variations in coffee dose or shot volume can significantly affect flavor. I targeted a 1:2 brew ratio—two grams of espresso for every gram of coffee. With a 10-gram dose, I aimed for around 20 grams of espresso. This precision helped me avoid over- or under-extraction.
Purge the Grinder Between Basket Changes
Switching between single and double baskets often requires adjusting the grinder. Purging the grinder of old grounds before each shot ensured consistency. Even slight variations in grind size can make a noticeable difference in extraction quality.
Tackling the Challenges of Single Baskets
Using the single basket required more patience and precision compared to the double basket, but the rewards were worth the effort. Once dialed in, the single basket produced concentrated shots that were particularly enjoyable in milk-based drinks like lattes. The flavor was subtler yet balanced, complementing milk without overpowering it.
For those who prefer lighter espresso or single shots for milk-based beverages, experimenting with the single basket can be rewarding. Each machine and palate are unique, so don’t hesitate to tweak your dose, grind, and extraction time to find what works for you.
Additional Tips for Mastering the Single Basket
Experiment with Pre-Infusion
If your machine supports pre-infusion, use it. Pre-infusion introduces a small amount of water to the coffee grounds before full pressure is applied, minimizing channeling and enhancing extraction consistency.
Keep Your Equipment Clean
Regular cleaning is essential for consistent results. Coffee oils and residue can accumulate quickly, affecting flavor and extraction. Clean the portafilter, basket, and machine parts frequently for optimal performance.
Choose the Right Coffee Beans
The choice of beans can greatly influence your single shots. Medium to dark roasts tend to work best with the single basket, delivering richer, more robust flavors. Light roasts, while flavorful, can be more temperamental and require precise extraction to avoid sour notes.
Concluding Thoughts: Achieving the Ideal Single Shot
Mastering the single basket on a Breville or Sage espresso machine demands patience and experimentation. The basket’s conical design poses challenges, but with adjustments to dose, grind size, and brew ratio, it’s possible to produce a balanced and flavorful shot. While the process may be more complex than brewing with the double basket, the rewards are well worth it.
A perfectly brewed single shot offers a clean, concentrated espresso that shines in various drinks, especially milk-based ones. Keep experimenting, learn from each attempt, and enjoy the journey toward brewing excellence. Happy brewing!
Frequently Asked Questions
Why does the single basket have a conical shape?
The conical shape accommodates smaller coffee volumes but can lead to uneven water flow, requiring careful adjustments for consistent extraction.
How much coffee should I use for a single shot?
Start with 10 grams of coffee and adjust based on your machine, beans, and flavor preferences.
Should I use the same grind size for single and double shots?
No, single baskets generally require a finer grind to achieve a slower, more even extraction.
Is a scale necessary for single shots?
Yes, a scale ensures consistency, helping you achieve the correct brew ratio for a balanced shot.
Why purge the grinder when switching baskets?
Purging removes residual grounds that may affect grind consistency, ensuring high-quality shots every time.
Can I use pre-ground coffee for a single shot?
While possible, freshly ground coffee yields superior flavor and consistency, particularly when fine-tuning the single basket.
