Rocket Espresso 58mm Bottomless Portafilter, E61, 21g Basket, RA99905022

The Rocket Espresso Milano 58mm Bottomless Portafilter (RA99905022) is a genuine Rocket accessory designed for compatible Rocket E61 espresso machines. Supplied in original Rocket Espresso packaging with a 21g filter basket included, it is the ideal upgrade for baristas looking to improve puck preparation and espresso extraction.

A bottomless or naked portafilter exposes the underside of the filter basket, allowing you to observe the extraction in real time. Uneven flow, multiple streams or spraying can reveal channeling and distribution issues, helping you refine your grind, distribution and tamping technique for more consistent espresso.

Manufactured to Rocket Espresso specifications, the portafilter features 5.7mm locking wings for a secure fit with compatible Rocket E61 group heads. Its open-bottom design also provides an unobstructed view of the espresso as it converges beneath the basket, making it both a useful diagnostic tool and a satisfying way to watch a well-dialled shot extract.

Compatible with standard 58mm filter baskets, it integrates easily into an existing Rocket espresso setup and is suitable for both home enthusiasts and professional barista workflows.
