Quick answer
The Espresso Series 1 is a home espresso machine that combines temperature stability and pressure control in an intuitive design, making it suitable for beginners and seasoned baristas alike.
Why temperature stability and pressure control matter
Consistent water temperature is crucial for extracting the full flavor from coffee grounds without bitterness. Pressure control lets you adjust the flow rate to match different coffee beans and roast levels, giving you more control over the final shot.
Who benefits most from the Espresso Series 1
This machine is designed for home users who want café-quality espresso without the complexity of commercial equipment. It's also great for baristas who want to practice dialing in shots at home.
Frequently asked questions
- What comes in the box?
- The Espresso Series 1 includes a 58 mm bottomless portafilter with an ergonomic plastic handle, plus a 2-year standard warranty. The machine itself features intuitive controls for temperature and pressure.
- How do I set up the machine for the first time?
- Fill the water tank, plug in the machine, and let it heat up for about 15 minutes. Run a blank shot (no coffee) through the portafilter to warm the group head and rinse the system. Then you're ready to dose and tamp. Always warm the group head before pulling your first shot.
- How do I adjust pressure and temperature?
- Use the front panel controls to increase or decrease the brew pressure and temperature. Start with the recommended settings for your coffee beans (e.g., 9 bars and 200°F for a medium roast), then tweak based on taste. Small adjustments can dramatically change extraction; keep a log of your settings.
- What if my espresso tastes sour or bitter?
- Sour espresso usually means under-extraction—try a finer grind or higher temperature. Bitter espresso means over-extraction—try a coarser grind or lower temperature. Adjust one variable at a time. Change only one variable (grind, dose, temperature, or pressure) between shots to identify the issue.
