KNODOS KNODOS001W 54 mm Bottomless Portafilter with Rosewood Handle

For home espresso drinkers who want to see how a shot is extracting, the KNODOS bottomless portafilter makes the flow visible as it leaves the basket. Its 54 mm size is designed for compatible Breville and Sage machines, and the included 18–21 g basket is ready for espresso preparation. What can a visible pour reveal? It lets you observe extraction in real time and spot channeling as it happens. A rosewood handle adds a natural finish to your espresso setup.

The open base gives you a direct view of the espresso stream, making this a practical tool for refining your puck preparation and monitoring a shot. It also provides a clear way to notice channeling during extraction rather than relying only on the finished drink. Compared with a traditional spouted portafilter, this design prioritizes visibility at the group head, which can be useful when adjusting your espresso routine. The stainless-steel body and rosewood handle bring together a functional brewing accessory and a distinctive detail for a home coffee station.

Best use cases

Use it when pulling espresso on a compatible 54 mm machine and you want to watch the pour from the basket. For example, during a morning dial-in, the exposed extraction can help you assess how evenly the shot is flowing and guide adjustments to your preparation. The included basket holds 18–21 g, while the bottomless format makes the extraction itself easy to observe. It is also a considered choice for an espresso setup where the handle’s warm wood appearance is part of the appeal.

Some buyers highlight the rosewood handle’s appearance and describe the portafilter as solid and straightforward to use. Feedback on sealing and weight is mixed, and some report splashing or excess dripping during shots. The exposed design makes the pour visible, so it suits users who value observing extraction as part of their espresso workflow.

Included in the pack

The pack contains the bottomless portafilter and an 18–21 g filter basket. Together, they provide the core components for using the open-portafilter format with the compatible machines listed above. The basket capacity is useful to know when setting up a dose, while the portafilter’s exposed base provides a view of the espresso flow during the shot.

What to clarify

Which espresso machines does it fit? It is listed for the Breville and Sage models named in the specifications, including Barista Express, Barista Pro, Barista Touch, Bambino, Bambino Plus, Infuser, Duo Temp Pro and Impress. Check your machine’s model against that list before choosing a portafilter.

What does bottomless mean here? The portafilter has an open base rather than spouts, so you can see the espresso extraction as it flows from the basket. That visibility can help you observe channeling while preparing shots.

Is a filter basket included? Yes. An 18–21 g filter basket is included with the portafilter.

Final verdict

The KNODOS 54 mm bottomless portafilter is suited to Breville and Sage owners who want a visible view of espresso extraction and a rosewood-handled accessory for their setup. Its included 18–21 g basket and open design make it a useful choice for practising shot preparation and observing the pour on a compatible machine.
