Our take
Mazzer's Mini Electronic B is the filter-holder-activated member of its on-demand electronic grinder line. The 2022 A/B brochure describes stepless micrometric adjustment, 64 mm flat 189D burrs, a 250 W motor, a standard 0.6 kg bean hopper, a die-cast aluminum body and 10.2 kg net weight. Mazzer identifies 189D as hardened steel. A secondary-hosted 2011 A/B manual describes separate single and double dose adjustments and a 4–19 g range; it does not document an integrated scale or measured dose accuracy. The row's black finish, source code and exact revision are not crosswalked, and no voltage, numeric duty rating or current offer is verified.
For a fixed espresso-counter workflow after confirming the exact revision; not for travel, specified duty or mandatory weighed dosing..
Not for portability, a confirmed voltage or sustained workload requirement, or a mandatory scale-based dose with independently verified accuracy.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Mazzer's product material defines B's portafilter-trigger workflow and stepless adjustment.
- The 189D burr record and A/B brochure provide model-level geometry, material and standard hopper details.
- Mazzer publishes care guidance that keeps the 189D separate from redesigned and manual/timer Mini configurations.
What to weigh up
- The 2011 dose range is from a reproduced manual and is not scale accuracy.
- Historical ASIN, code, finish, exact hopper and regional voltage are not mapped.
- The cited A/B generation has no comparable throughput or continuous-duty rating.
The key details
| Model covered | Electronic B / 189D family documentation; source code, finish and exact revision unresolved |
|---|---|
| Grind and dose controls | Maker-documented stepless micrometric control; 64 mm flat 189D hardened-steel burrs in the A/B configuration. |
| Capacity and use | 2022 brochure lists 250 W and a 0.6 kg standard hopper; voltage and fitted row hopper remain unresolved. |
| Fit and limitations | The older electronic B is distinct from Electronic A and the redesigned Mini; current offer and duty are unknown. |

What the features mean for you
Electronic B is distinct from other Mini versions
Mazzer defines Mini Electronic B by activation through the filter holder; Electronic A uses a button panel. Both are separate from the older manual/timer Mini with 182D burrs and from the redesigned current Mini. This distinction matters because later motor, burr, hopper and daily-output specifications cannot be transferred backward to row 413. The saved title names Electronic Type B, but its numeric source code 4335456992, black finish and historical ASIN are not mapped by Mazzer to a precise revision. Treat the profile as model-level guidance and verify the offered unit's label and supplied documentation.
Stepless controls and on-demand operation
Mazzer's Mini B feature page describes stepless micrometric adjustment, electronic on-demand dose adjustment and the filter-holder trigger. The official 189D record identifies flat, hardened-steel burrs at 64 mm for the A/B configuration. These construction and workflow facts can help compare a fixed espresso counter setup, but they are not a test of particle distribution, extraction or repeatability. The available material does not establish the exact row's installed revision or provide a performance score. Buyers should distinguish the physical control format from claims about the resulting cup.
Dose controls are electronic, not a verified scale
A reproduced 2011 A/B manual describes independent single and double adjustments across a 4–19 g range. This gives a dose-oriented workflow, but the saved document is not an integrated weighing scale specification and offers no independent mass accuracy or repeatability result. The profile therefore does not treat this as a gram-target match. The 2022 brochure's 0.6 kg hopper is a standard A/B figure, with 320 g and 1 kg alternatives listed as options; the row's exact fitted hopper is not known. The grounds receiver size is also not documented in the saved source set.
Installation, workload and care need confirmation
The A/B brochure lists 250 W and motor speed by supply frequency, but does not give a voltage rating. RPM entries for 50 and 60 Hz are not a substitute for an electrical nameplate. The cited A/B sources also provide no comparable run/rest limit, throughput or daily-volume rating. Mazzer advises frequent dry cleaning and lists an indicative 400 kg 189D service life; these are maintenance directions, not a durability test or commercial duty rating. Confirm installation supply and expected workload for the exact version before using the model in a café specification.
Conditional fit for a stationary espresso workflow
A buyer who wants a filter-holder trigger, stepless adjustment and electronic single/double operation may find the Mini B configuration relevant after confirming the offered revision. Its maker-described construction supports a comparison, not a guarantee of espresso quality. It is a substantial stationary grinder rather than a portable item, and its voltage, exact hopper, daily duty and current availability are not established for row 413. No exact Amazon offer, price, measured retention, noise or dose performance is claimed. Use the labeled model search, then check the nameplate, hopper fitted and included portafilter support.
What else to compare
Before you buy
How does Mini Electronic B activate?
Mazzer describes B as filter-holder activated; the A configuration uses its button panel.
What burr set is documented for the A/B model?
Mazzer identifies 64 mm flat 189D hardened-steel burrs for Mini Electronic A/B.
What is the standard hopper in the 2022 brochure?
The brochure lists 0.6 kg standard, with 320 g and 1 kg alternatives as options.
Does the 4–19 g range mean the grinder weighs coffee?
No integrated scale or dose accuracy is documented by the reproduced manual range.
Can the current redesigned Mini specifications apply here?
No. The redesigned motor, burrs, hopper and 1 kg/day guidance belong to a different generation.
Is the historical ASIN a current Mazzer offer?
No current exact offer or row-specific revision mapping was verified in the saved research.
Where can I check the current price?
