## Notes

De'Longhi's Dedica Maestro Plus uses De'Longhi's own **51mm portafilter** — a
proprietary size shared across the Dedica and La Specialista lines, and one that
is **not interchangeable** with the 58mm commercial standard, the 54mm Breville
format, or the 52mm La Pavoni lever size. Standard 58mm baskets, tampers and
bottomless portafilters do not fit.

It ships with both **single-wall (non-pressurized)** and **dual-wall
(pressurized)** filter baskets in 1- and 2-cup sizes, up to a 20 g dose — the
single-wall basket for dialling in with a good grind, the dual-wall for
pre-ground or convenience. The 51mm size is confirmed by De'Longhi's own DLSC085
bottomless-portafilter page, which states a "51mm DIAMETER" and lists the Dedica
Maestro line among the machines it fits; the included basket types are quoted
from De'Longhi's own EC950M product page. Both read firsthand on 2026-07-24.

  - Official De'Longhi (US) DLSC085 Bottomless Portafilter accessory page, read firsthand 2026-07-24. States the portafilter is '51mm DIAMETER.' and is 'Compatible with all De'Longhi La Specialista and De'Longhi Dedica Maestro models.' The Dedica Maestro Plus is a Dedica Maestro model, so its portafilter is 51mm — De'Longhi's own accessory page carries the whole size-to-machine chain.

  - Official De'Longhi (US) Dedica Maestro Plus EC950M product page, read firsthand 2026-07-24. Confirms the model name 'Dedica Maestro Plus' and that it ships with 'both single and double wall filter baskets with up to 20g dose': 'The single wall basket allows you to brew like a pro, giving you greater control', while 'the double wall basket is more forgiving, better suited for beginners and store-bought pre-ground coffee beans.' So both non-pressurized (single-wall) and pressurized (dual-wall) baskets are included.
