- No more channelling! The matrix material structure ensures uniform flow, reducing the risk of channelling even with poor tamping.
- Cleaner groups! Coffee silt does not travel back up the solenoid valve, but coffee oils do - so you still have to back-flush. However, oily molecules can still travel back with the water being chucked at the end of the action.
- Get more out of less - Improving the flow on top of the coffee allows the barista to grind the coffee finer and use less to achieve a similar result.
- Thicker, creamier espresso - the micro-bubbles created inside the tiny crevices of the material make their way into the coffee brew. With the fats and fibres, these micro-bubbles build a thicker crema and full body feel.
- Lowers the group temperature by 1-2°C - if the basket is not heated up beforehand.

💡* While it slows the extraction and drops the group temperature, it can absorb the coffee grounds. For a cleaner shower, you can use a Paper Puck Screen.
