## Notes

The Oracle Dual Boiler pairs Breville's automatic grind-dose-tamp Oracle front
end with a dual-boiler brew/steam layout. Like the rest of the Oracle line it
uses the **58mm** commercial standard — Breville's page states a "Professional
58mm stainless steel portafilter holds a 22g dose" — so 54mm parts from the
Barista and Bambino lines do not fit, and 58mm ones do.

It ships with **single-wall (non-pressurized)** 1-cup and 2-cup baskets only,
which follows from the automatic tamping: there is no dual-wall basket in the
box. Breville's 58mm accessories state compatibility with "58mm Breville"
machines and are cross-referenced here.

Not to be confused with the [Dual Boiler](/machines/breville-dual-boiler/)
(BES920), which is also 58mm but is manually operated and ships with both
single- and dual-wall baskets. As with the Oracle Jet, IMS's B70 list names only
"BREVILLE (The Oracle)", so we do not extend it to this model. Verified against
Breville's official US product page on 2026-07-26.
