Our take
The Grinta AMMT is the timed-stop branch of Nuova Simonelli's Grinta family. The manufacturer handbook describes an adjustable run time that stops automatically; it does not document saved single/double presets or a weight scale. The archived brochure lists a 50 mm burr size, a 0.5 kg bean hopper and home/office low-volume use. Its Grinta column lists 230 V/50 Hz and 115 V/60 Hz options, but not phase or connector and not the historical candidate's exact supply. Its 3.6 kg/h productivity figure is a maker statement, not independently measured sustained throughput. The handbook's family supply range and 24-hour intermittent-service language do not establish the offered machine's complete nameplate or numeric daily workload. Row 255's `AMM 5021` title clue does not prove it is AMMT; keep the timed variant separate and confirm the model label. No current exact Amazon offer or firsthand result is claimed.
Low-volume home/office users who prefer timed stopping and verify the unit label; unsuitable for weight dosing or unsupported high-volume claims..
A hard requirement for scale-measured dosing, saved single/double time presets, manual hold-to-grind, or high-volume/continuous duty based only on the maker brochure figure or family service statement.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The handbook documents an AMMT automatic stop adjusted by run time.
- The archived brochure lists a 50 mm burr size and separate 0.5 kg bean hopper for the family.
- The maker positions the family for low-volume home/office use and documents a portafilter receiving workflow.
What to weigh up
- Automatic timing is not weight dosing; no scale or gram target is documented.
- AMMT is not the manual hold-to-grind AMM version, and no saved pair of timed dose presets is documented for this branch.
- The historical row's AMM clue does not identify AMMT; the brochure's 230 V/50 Hz family option does not prove this unit's phase, connector or electrical label.
- The 3.6 kg/h figure does not establish sustained output or commercial duty.

What the features mean for you
Suitable use
A model-level low-volume home/office comparison when a timed automatic stop and portafilter workflow suit the buyer, after the offered unit is confirmed as the AMMT variant. The manual distinguishes this timed version from manual AMM, which runs while its control is held. That control distinction matters when the buyer requires continuous manual operation instead of an automatic stop.
Limits and unresolved facts
AMMT's adjustable time stop is not a scale, and the reviewed manual does not document stored single/double presets for this branch. Do not transfer AMM's hold-to-run behavior. The source row says AMM but is not crosswalked; the maker brochure's 230 V/50 Hz option does not state phase/plug or identify this unit. Exact supply, duty and current offer remain unknown.
Questionnaire reasoning
A shopper who requires AMMT's automatic timed stop may use it only after the variant is verified. A hard manual-hold or weight-dose requirement is not met by this profile. The 0.5 kg bean hopper is separate from grounds capacity. Treat the maker's 3.6 kg/h figure as a specification rather than verified sustained service; the brochure's 230 V/50 Hz model option does not resolve exact phase, plug or unit identity for a fixed installation gate.
Timed AMMT operation
Nuova Simonelli's handbook describes AMMT as stopping automatically at an adjusted run time; this is one timed-duration control, not a pair of saved single/double dose presets and not a scale. The maker brochure lists 50 mm burrs, a 500 g family hopper and low-volume home/office positioning. Its 3.6 kg/h output figure is a maker specification, not a verified sustained-duty result.
Version and electrical fit
Check that the offered unit is labeled AMMT before applying its timed-stop profile; row 255's AMM clue does not map the historical ASIN to this version. The brochure lists 230 V / 50 Hz and 115 V / 60 Hz family options but does not establish phase, connector or the specific unit plate. Confirm exact supply and intermittent-service instructions at the machine. Current Amazon identity, condition and availability remain unverified.
What else to compare
Before you buy
How does AMMT stop grinding?
The handbook describes an automatic stop adjusted by run time.
Does it weigh the dose?
No scale or gram target is documented.
Does it have separate saved single/double presets?
The reviewed AMMT description documents one adjusted run time, not a saved pair of timed doses.
Is AMMT the same as manual AMM?
No. AMM runs while its button is held; AMMT stops automatically by time.
Does row 255 identify AMMT?
No. Its title clue says AMM 5021 and does not prove the separate timed variant.
Does the brochure prove a 230 V single-phase AMMT unit?
No. It lists a 230 V/50 Hz Grinta family option but does not establish the exact row version, phase or plug.
Is it suitable for continuous commercial service?
The maker brochure's 3.6 kg/h figure is not a verified sustained-duty rating; the manual describes intermittent service.
Is a current exact Amazon offer verified?
No current exact Amazon offer is independently verified for this model; use the labeled model search only to locate candidates.
