## Notes

The Mozzafiato is Rocket Espresso's dual-boiler domestic sibling to the Giotto
— the same E61 prosumer platform in a rounded body. This entry is **measured
tier**: Rocket's catalogue prints no portafilter diameter for the Mozzafiato,
but IMS's competition catalogue names ROCKET in its 58/58.4mm B70 series (a
basket maker's measured fitment) and Rocket's E61 domestic line is the 58mm
standard (Rocket names the "E61 brew group" on the Appartamento and Porta Via
pages of the same catalogue). As a 58mm E61 machine it takes any standard 58mm
basket — the VST and IMS B70 baskets here fit. Verified at the measured tier on
2026-07-15; a Rocket page printing "58mm" would lift it to
manufacturer-verified.

  - Official IMS Filtri competition catalogue, read firsthand 2026-07-13. IMS's 'For tamper 58 / 58.4' B70 basket compatibility list names ROCKET — a basket maker's published (measured) fitment placing Rocket-brand machines in the 58mm standard. This is the measured basis for the diameter here.

  - Official Rocket Espresso domestic catalogue, read firsthand 2026-07-15. Presents the Mozzafiato Fast as part of 'Rocket's dual-boiler legacy' — a PID, dual-boiler E61 domestic machine (1.8 L boiler), available in tank (V) or plumbed-in (R) versions. The catalogue does not print a portafilter diameter for the Mozzafiato specifically, which is why this sits at the measured tier.
