Key features and how they affect the cup

PID-controlled heated group
Temperature management extends beyond the brew boiler to improve stability at the group.
58 mm portafilter and 22 g dose
The professional-style format supports a broad 58 mm accessory ecosystem; always verify basket and tamper fit.
Programmable extraction
Use volumetric or timed control, adjust temperature, and refine pre-infusion for different coffees.
Manual steam power
The dedicated steam boiler provides immediate steam on demand for deliberate microfoam texture.

Dialing in and daily workflow
- Use fresh coffee and begin near the machine’s recommended dose.
- Distribute the grounds evenly and keep the portafilter rim clean before locking in.
- Watch flow and shot time, but make the final decision by taste. Grind finer for a very fast, thin shot and coarser for a choked or overly slow shot.
- Texture milk immediately after extraction when making a milk drink, then purge and wipe the wand.
- Change only one grind, dose, yield, or temperature variable at a time so the result is understandable.

Cleaning and ownership
Use suitable low-scale water within Breville’s guidance, backflush and run cleaning cycles as directed, purge the steam wand, and replace filters on schedule. Warm the group, portafilter, and cups before demanding temperature-sensitive results. Keep the separate grinder calibrated as beans age.
