What size accessories do I need for my Breville Dual Boiler or Oracle?
Breville Dual Boiler and Oracle machines use a commercial standard 58mm portafilter. For optimal results, we recommend 58mm or 58.5mm accessories to ensure a perfect fit. This size is larger than the 54mm used in Barista Express models, so be sure to select tools specifically designed for 58mm compatibility.
Which accessories will most improve my espresso quality with a Breville Dual Boiler?
The most impactful accessories are a precision 58mm self-leveling tamper, a distribution tool for even coffee beds, a bottomless portafilter for diagnosing extraction issues, and a WDT tool for breaking up clumps. For convenience, a magnetic dosing ring and tamping station can significantly streamline your workflow.
How do the Breville Dual Boiler and Oracle differ from other Breville machines?
The Dual Boiler and Oracle feature separate boilers for brewing and steaming, allowing simultaneous operation unlike single-boiler machines. They use commercial-standard 58mm portafilters (versus 54mm in other models), offer PID temperature control for precision brewing, and include pre-infusion functionality. The Oracle adds automated grinding, dosing, and tamping for additional convenience.
