the Naked Portafilter 58

The Naked Portafilter 58 is a professional-grade bottomless portafilter designed for 58 mm commercial espresso machines. Engineered to provide full visual access to the extraction process, it allows baristas and users to diagnose channeling, improve distribution technique, and optimize espresso shot quality with greater precision.

Machined for durability and accuracy, the open-basket design removes the spout assembly, enabling direct espresso flow from the puck into the cup. This configuration enhances feedback during extraction, making it an essential tool for dialling in grind size, tamp consistency, and puck preparation technique in specialty coffee workflows.

The ergonomic handle is designed for stability and comfort during repeated use, while the solid metal construction ensures long-term reliability under commercial or advanced home espresso conditions.
