The buying decision

Is the Faustino 3.1 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

Faustino 3.1 repeats a dose using time. Weigh the output when setting up a recipe and recheck after changing beans or adjustment. Repeating a duration is useful assistance, but it does not guarantee a fixed grounds mass.

Read the adjustment, not just the burr size

The documented adjustment is Stepless · single revolution. The burr diameter is 50 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.
