De’Longhi’s own bottomless (naked) portafilter for its 51mm machines, with a rosewood handle. Removing the spout exposes the underside of the basket so you can watch the extraction directly — even, mirror-like flow means an evenly tamped, evenly distributed puck, while sprays and jets pinpoint channelling. It is the single most useful tool for dialling in a grind, which is why “De’Longhi bottomless portafilter” is a common search among Dedica and La Specialista owners.
De’Longhi’s page states it is “51mm DIAMETER” and “Compatible with all De’Longhi La Specialista and De’Longhi Dedica Maestro models” — De’Longhi’s own 51mm portafilter standard, which is not interchangeable with 54mm Breville or 58mm commercial parts. It is cross-referenced here to the Dedica Maestro Plus; as more of De’Longhi’s 51mm machines are added to the database, they will be listed here too.
