The buying decision

Is the Opus Gen 2 right for your setup?

Our interpretation of the documented features. Performance, taste and long-term reliability have not been independently tested.

Choose the dosing routine

Opus Gen 2 is arranged for individual doses. Consider it if changing beans is part of your routine, and include weighing and transferring the dose in your comparison. A single-dose design does not establish zero retention; no independently measured retention figure is claimed here.

Read the adjustment, not just the burr size

The documented adjustment is Stepless. The burr diameter is 48 mm. Use those details to compare hardware and how you will record a setting. They do not establish a flavor ranking, measured grind speed or noise level. If you change brew methods, allow time to check the espresso recipe when returning.

Plan access and the handoff

Check the assembled height with the selected hopper and room to remove its lid. Confirm whether your portafilter is supported directly or whether you will transfer grounds from a cup. Read the burr-access and cleaning instructions before choosing a position beneath a cabinet; published body dimensions are not a service-clearance specification.
