## Notes

Verified against Breville's official US product page on 2026-07-05. The Dual
Boiler BES920 is one of Breville's three 58mm machines (with the Oracle and
Oracle Touch) — not the proprietary 54mm of the Barista/Bambino lines — and
unlike the auto-tamping Oracles it ships with both single-wall
(non-pressurized) and dual-wall (pressurized) baskets in 1-cup and 2-cup
sizes. Note: IMS's B70 list names "BREVILLE (The Oracle)" specifically, so
this entry carries no IMS cross-reference.
