MORILS 58mm Bottomless Portafilter with Double Shot Basket & Walnut Handle (Breville) Review (2026)

Who a bottomless portafilter suits

A bottomless, or naked, portafilter removes the usual spouts at the bottom so you can watch espresso flow straight out of the basket as it extracts. This suits a Breville 58mm machine owner who already has the basics of dosing and tamping down and wants direct feedback on channeling, uneven extraction, or off-center pours that a closed portafilter hides from view. It is a poorer fit for someone brand new to espresso, since watching unfiltered flow can be messy and a little intimidating before your prep technique is consistent, and it will not fix bad grind or tamp on its own.

Materials and included basket

The portafilter pairs a metal body and basket assembly with a walnut wood handle, giving it a warmer, more furniture-like look than the stock plastic or steel handles that ship with most machines. It comes with a double shot filter basket already included, so it is ready to brew as soon as it is installed rather than requiring a separate basket purchase, and MORILS also lists a stainless steel puck screen as part of the accessory set, which sits on top of the coffee bed to help distribute water more evenly and reduce channeling during the shot, an upgrade some rival bundles leave out.

Compatibility with Breville machines

This portafilter is sized for the 58mm group head used on Breville's higher end machines, and MORILS lists it as compatible with the Breville Barista Express style 900 series and other Breville machines that share the 58mm standard. Because Breville also sells 54mm machines in some of its lineup, it is important to check your specific model's group head size before ordering, since a 58mm portafilter will not fit a 54mm group and vice versa. Buyers upgrading from a stock portafilter should confirm their model number against the compatibility list rather than assuming by machine name alone.

Learning curve and mess

Because a bottomless portafilter has nothing to catch or slow uneven flow, a bad tamp, an off-center dose, or a stale grind setting can cause coffee to spray sideways rather than pour down cleanly into the cup, which is a normal part of the learning process rather than a defect in the portafilter itself. Expect some cleanup on the machine's drip tray and group head area while you dial in a consistent routine, and expect that improvement in your prep technique will show up directly as cleaner, more centered pours once channeling issues are corrected.

Where it fits in a home setup

For a Breville 58mm owner who already owns a decent grinder and wants to get more consistent shots, this portafilter is a relatively low cost way to add real time feedback to an existing machine rather than upgrading the whole machine. The walnut handle also gives an otherwise stock-looking machine a more premium feel on the counter. Just know going in that it demands more attention to prep than a standard portafilter, and the payoff is diagnostic information about your technique rather than any change to the machine's underlying boiler or pump performance. Pair it with a consistent burr grinder and a scale for dosing, and it becomes a useful long term training tool for improving technique rather than a one-time novelty accessory.
