the Naked Portafilter 54

The Naked Portafilter 54 is a bottomless espresso portafilter designed for 54 mm group head systems, providing full visibility of the espresso extraction process. It is engineered to help users diagnose puck preparation issues such as channeling, uneven distribution, and tamping inconsistencies, enabling more precise control over espresso quality.

By removing the spouted base, the open design allows espresso to flow directly from the basket into the cup, offering immediate visual feedback during extraction. This makes it an essential tool for dialing in grind size, improving distribution technique, and refining tamping consistency in both home and professional espresso workflows.

The ergonomically designed handle provides stability and comfort during repeated use, while the durable metal construction ensures long-term reliability under regular brewing conditions.
