Real-time Shot Diagnosis – with Open-Bottom Design
Open-bottom construction exposes the coffee puck and the extraction flow during a pull, making it possible to see channeling, uneven flow or puck deterioration. Visual access helps correlate visible faults with grind size, dose and tamp technique.
Visual feedback allows quick adjustments to grind and tamping for cleaner, more consistent shots.
Consistent Dosing and Fit – thanks to 18–21g Optimisation
Engineered around an 18–21g coffee dose and a 58mm basket, the fit promotes even compression and water distribution across the puck. Compatibility with common precision baskets maintains consistent basket geometry and flow.
A stable dosing range helps deliver repeatable extractions and reduces shot-to-shot variability in a busy workflow.
Durable, Comfortable Handling – with Stainless Steel and Walnut
Corrosion-resistant stainless steel construction pairs with an ergonomic rosewood/walnut handle designed to reduce heat transfer and provide balance during hands-on use. Solid materials resist wear from routine café or home use.
A satisfying weight and balanced ergonomics make frequent use comfortable while promising long-term durability according to user feedback.
