Description

Bottomless Filterholder 21g Capacity

The bottomless filterholder — also called the 'naked' filterholder — has become an essential tool for quality-focused baristas. Designed for Rocket machines, this portafilter improves espresso extraction by providing complete visibility of the brewing process, helping baristas diagnose channelling and extraction issues in real time.

With a 21g capacity, this bottomless filterholder delivers improved extraction quality, greater crema volume, and enhanced sensory characteristics. The open-bottom design eliminates residue build-up and carbon deposits that can cause burnt flavours during extraction.
