Sage | the Naked Portafilter™ 54mm

A bottomless (naked) 54mm portafilter. Take the spout off and you can watch the extraction happen, so channelling, uneven tamping, and a bad distribution all show up instantly in the stream. The single most useful diagnostic upgrade for dialling in espresso at home. Stainless steel basket with a walnut handle. Fits the Bambino, Bambino Plus, Barista Express, Barista Pro, Barista Express Impress, and Barista Touch Impress.
