## Notes

The Oracle Jet is one of the **58mm** machines in Breville's range, not the
proprietary 54mm format used by the Barista and Bambino lines — so 54mm baskets,
tampers and portafilters do **not** fit it, and 58mm ones do. Breville's own page
states a "Professional 58 mm stainless steel portafilter holds a 22g dose".

Like the other Oracle models it grinds, doses and tamps automatically, so it
ships with **single-wall (non-pressurized)** 1-cup and 2-cup baskets only — no
dual-wall basket is included. Breville's 58mm accessories (the Naked Portafilter
58mm, Force Gauge Tamper 58mm, Distribution Duo 58mm and the 58mm shower-head
seal) all state compatibility with "58mm Breville" machines and are
cross-referenced here.

One deliberate gap: IMS's Competition catalogue names "BREVILLE (The Oracle)" in
its B70 compatibility list — the Oracle specifically. We do not extend that list
to the Oracle Jet, because IMS has not said so; see
[how we verify](/methodology/). Verified against Breville's official US product
page on 2026-07-26.

  - Official Breville (US) product page for the Oracle Jet BES985, read firsthand 2026-07-26. States verbatim: 'Professional 58 mm stainless steel portafilter holds a 22g dose'. The included baskets are listed as 'Single wall 1 cup filter basket' and 'Single wall 2 cup filter basket' — single-wall (non-pressurized) only, no dual-wall basket in the box.
