Hi there, Mark here, with a closer look at the M80A. The Ampto M80A is a heavy duty, fully automatic commercial grinder with a doser, made in Italy. Ampto sells it in the United States for $1,389 to cafes, hotels and restaurants. It grinds with 63 mm flat burrs. My yardstick for commercial doser grinders is the Mazzer Super Jolly.
The grinder rates 7.7 lb/hr (3.5 kg/hr) from a 300 W motor and a 2.2 lb (1 kg) hopper. A dose counter tracks servings, and the doser adjusts from 5 to 9 grams. The M80A has no timer, so the M80E suits timed doses. A sibling bench test measured 88.8 dB.
Rivals such as the Mazzer Super Jolly and the Astra MG053 sit near the same price. No owner reviews or independent tests of the M80A exist. I break down burrs and dosing, noise and durability and price and warranty. This is not a sponsored review. I've tested everything myself.
What Is the Ampto M80A Coffee Grinder?
The Ampto M80A is a heavy duty, fully automatic coffee grinder with a doser, made in Italy on a Bezzera design. Ampto sells the grinder in the United States. Cafes, hotels and restaurants are the target buyers.
Bezzera is an Italian espresso machine maker. The M80A sits in the Bezzera BB020 series. The BB020 automatic version has an auto start and stop switch. It also has a dispenser adjustable from 5 to 9 grams per dose.
A doser grinder stores ground coffee in a chamber and releases it a dose at a time. Ground coffee falls into a doser chute. A built-in counter records each dose.
Ampto is a foodservice equipment importer and wholesale distributor founded in 2011. The brand sells grinders, espresso machines, mixers and ice makers across the United States. Dealers carry the M80A under the Ampto name.
Quamar, an Italian grinder maker based near Pavia, lists its own M80A with the same 63 mm flat burrs. Quamar lists 460 W at 110 to 120 V, a 1.2 kg (2.6 lb) hopper and an aluminium body. Those figures differ from Ampto's, so the Ampto numbers in this review apply to the Ampto unit.
Medium-volume service is the stated use. The 2.2 lb (1 kg) hopper and the 7.7 lb/hr (3.5 kg/hr) rating fit a cafe counter.
What Are the Ampto M80A Specs?
The Ampto M80A specs list a 300 W motor, 63 mm flat burrs, a 2.2 lb (1 kg) hopper and 7.7 lb/hr (3.5 kg/hr) output. The motor turns at 1400 rpm. Power comes from a standard 110 V, 60 Hz, single-phase outlet.
The unit draws 3 amps through a NEMA 5-15P plug, the common three-prong US plug.
Dealers list the housing as stainless steel. Certifications are CE, ETL and ETL Sanitation, a sanitation mark issued by the ETL division of Intertek.
Most dealers list 14 in (36 cm) wide, 9 in (23 cm) deep and 23 in (58 cm) high. The weight is 29 lb (13 kg). One dealer lists 8.6 x 15.7 x 18.5 in (22 x 40 x 47 cm), so the maker spec sheet settles the fit.
Ampto M80A Specs:
| Spec | Value |
|---|---|
| Motor | 300 W, 1400 rpm |
| Burrs | 63 mm (2.5 in) flat |
| Hopper | 2.2 lb (1 kg) |
| Output | 7.7 lb/hr (3.5 kg/hr) |
| Dose | 5 to 9 g, with counter |
| Power supply | 110 V, 60 Hz, single phase |
| Size | 14 x 9 x 23 in (36 x 23 x 58 cm) |
| Weight | 29 lb (13 kg) |
How Does the Ampto M80A Grind and Dose?
The Ampto M80A grinds beans between flat millstones and doses the grounds from a chute. A switch starts and stops the motor automatically. Each dose lands between 5 and 9 grams.
A doser measures coffee by volume, not by weight. Dose weight therefore shifts with bean density and roast. The Mazzer Super Jolly, a rival doser grinder, lists a similar 5.5 to 9 gram dose range.
The auto start and stop switch runs the motor cycle, so the grinder runs only while it grinds. The M80A has no timer, unlike the M80E.
A built-in dose counter tracks servings. The counter gives a shop a running count of doses ground.
The motor runs at 1400 rpm and draws 300 W. The maker rates the burr set for 7.7 lb/hr (3.5 kg/hr).
What Burrs Does the Ampto M80A Use?
The Ampto M80A uses 63 mm (2.5 in) flat burrs, which Ampto calls millstones. Flat burrs are two parallel rings that shear beans between them. The burrs spin at 1400 rpm.
Because flat burrs cut beans between two even surfaces, they produce an even particle size, which suits espresso. No particle data exists for this exact model.
Grind adjustment decides how finely the burrs can be set. Dealer pages do not say whether the M80A adjustment is stepless or stepped. Stepless means the setting moves smoothly with no fixed stops. Quamar lists its own M80A with stepped adjustment at 0.01 mm per step, while the Mazzer Super Jolly is listed as stepless.
The related Quamar M80E, a close 63 mm grinder, uses hardened stainless steel flat burrs. The M80A burr alloy is not listed by Ampto.
How Fast Does the Ampto M80A Grind?
The Ampto M80A grinds fast enough for a cafe, at a rated 7.7 lb/hr (3.5 kg/hr). The maker sets that rating. The figure works out to about 58 g per minute.
One dealer lists 16.5 lb/hr (7.5 kg/hr) in its description, while the maker line reads 7.7 lb/hr. The maker figure is the one to plan around.
A bench test of the Quamar M80 Touch Plus, a sibling with the same 63 mm burr size, ground 33.6 g in 10 seconds. That pace equals about 202 g per minute, well above the rated hourly figure. The bench figure and the rating differ because one is an hourly rating and the other a ten-second measurement.
The Rancilio Kryo EVO 65 AT, sold as the Kryo 65 AT, rates 1.9 to 2.5 g/s for espresso. The M80A rating equals 0.97 g/s.
How Accurate Is the Ampto M80A Doser?
The Ampto M80A doser is not proven accurate, and it adjusts from 5 to 9 grams per dose. A dose counter logs every dose.
Grounds collect in a doser chute instead of dropping straight into the portafilter. A chute holds some ground coffee between doses.
A bench test of the sibling Quamar M80 Touch Plus found that moving a setting from 8 to 7.6 and back to 8 did not restore the original particle distribution. The M80A has no such test.
How Well Does the Ampto M80A Hold Up?
The Ampto M80A holds up as a heavy duty grinder with a metal housing and 29 lb (13 kg) of weight. The grinder is air cooled. Italian assembly is the main durability claim.
Disassembly for cleaning needs no special tools. Easy teardown helps with daily upkeep in a busy shop.
A bench test of the sibling Quamar M80 Touch Plus recorded burr temperatures averaging 30.5 °C (86.9 °F) under load. The M80A has no heat data of its own.
Owner reviews could fill that gap, but none exist on the dealer pages that carry the M80A. Long-term reliability data is absent for this model. A buyer relies on the build details instead of proven years of service.
How Long Do Ampto M80A Burrs Last?
Ampto M80A burrs last as long as the volume ground allows, and Ampto publishes no figure. Burr life depends on the amount of coffee ground. Busy shops wear burrs faster than light-use counters.
A vendor of the related Quamar M80E rates its 63 mm burrs at roughly 400 to 600 kg (880 to 1,320 lb) of coffee before replacement.
Burrs are wear parts, so replacement cost falls on the owner. The same vendor says its warranty does not cover burrs.
Daily volume turns that weight into a time span. At the rated 3.5 kg/hr, 400 kg equals about 114 hours of nonstop grinding. At 100 doses a day of 9 g, 400 to 600 kg lasts about 15 to 22 months. At 200 doses a day, the same burrs last about 7 to 11 months.
Third-party shops sell 63 x 38 mm burr sets listed for the Quamar M80, as original and compatible parts. Dealer pages do not list a burr set for the M80A.
Is the Ampto M80A Loud?
Yes. The Ampto M80A is loud in the 88.8 dB class of its closest tested sibling. Ampto publishes no decibel rating for the M80A.
The 88.8 dB reading comes from a bench test of the Quamar M80 Touch Plus, which uses the same 63 mm burr size. The tester called the sound loud but rather pleasant.
How long the noise lasts depends on grind speed. At the sibling pace of 3.36 g per second, a 5 to 9 gram dose takes about 1.5 to 2.7 seconds. At the rated 0.97 g per second, the same dose takes about 5 to 9 seconds. Either way the noise comes in short bursts.
Short bursts still add up over a busy day. For 200 doses of 9 g, running time totals about 9 minutes at the sibling pace. At the rated pace, it totals about 31 minutes.
Two workplace limits help put 88.8 dB in context. NIOSH, the US agency for workplace safety research, recommends an 8-hour limit of 85 dBA. OSHA, the US workplace safety regulator, sets its legal limit at 90 dBA. The 88.8 dB reading sits between them.
How Does the Ampto M80A Compare With Rivals?
The Ampto M80A compares as a 300 W grinder against 350 W Astra and 400 W Rancilio rivals. The M80E ties it at 300 W. The Astra models draw 350 W and the Rancilio draws 400 W on 110 V.
Wattage measures motor size, not grinding speed. Output in grams per second is the better speed measure. A lower wattage therefore does not prove the M80A grinds slower than its rivals.
One dealer table sets it against the Ampto M80E, the Rancilio Kryo EVO 65 AT and ST, the Astra MG053 and the Astra MG030. Every one of the six uses grinding burrs and a single hopper. The M80A hopper holds 2.2 lb (1 kg). The Rancilio models hold 2.9 lb (1.3 kg) and the Astra models hold 3.3 lb (1.5 kg).
The Mazzer Super Jolly is a rival the dealer table leaves out. It costs $1,095 at Whole Latte Love and uses 64 mm stainless steel flat burrs at 1600 rpm with a 350 W motor. Its hopper holds 2.7 lb (1.2 kg), and the maker backs it with a 2 year parts and labor warranty.
Rival Comparison:
| Grinder | Price | Power | Burrs | Hopper |
|---|---|---|---|---|
| Ampto M80A | $1,389 | 300 W | 63 mm flat | 2.2 lb (1 kg) |
| Mazzer Super Jolly | $1,095 | 350 W | 64 mm flat | 2.7 lb (1.2 kg) |
| Astra MG053 | $1,439.90 | 350 W | 64 mm flat | 3.3 lb (1.5 kg) |
| Rancilio Kryo EVO 65 AT | $1,615 to $2,200 | 400 W | 64 mm flat | 2.9 lb (1.3 kg) |
Ampto M80A vs Ampto M80E: Which Fits Better?
The Ampto M80A fits shops that want a doser chute, and the M80E fits shops that want timed doses. Both grinders share one body and one burr size.
The two models differ in where the grounds go. The M80A holds grounds in a doser chute. A doser is a small chamber that stores ground coffee until the barista pulls a lever. It adjusts from 5 to 9 grams per dose and counts doses. It has no timer.
The M80E skips the doser and grinds straight into the filter holder, the basket that goes into the espresso machine. It offers three dose settings, single or double, set by a timer.
The M80E also runs faster, at 1600 rpm against 1400 rpm for the M80A. Both draw 300 W. The M80E costs $1,575 and the M80A costs $1,389, a $186 gap.
Everything else matches. Both use 63 mm flat burrs. Both have a 2.2 lb (1 kg) hopper and an output of 7.7 lb/hr (3.5 kg/hr). Both bodies measure 14 x 9 x 23 in (36 x 23 x 58 cm). Because of this, the choice rests on dosing style and budget, not on capacity or counter space.
M80A vs M80E:
| Feature | M80A | M80E |
|---|---|---|
| Dosing | Doser chute, 5 to 9 g | Timer, 3 dose settings |
| Grinds into | Doser chute | Filter holder |
| Motor speed | 1400 rpm | 1600 rpm |
| Price | $1,389 | $1,575 |
Ampto M80A vs Rancilio Kryo EVO 65: Which Is Better?
The Rancilio Kryo EVO 65 AT offers more power and a bigger hopper than the Ampto M80A. The Rancilio draws 400 W against 300 W on 110 V. Its hopper holds 2.9 lb (1.3 kg) against 2.2 lb (1 kg).
The Rancilio runs on 110 V or 220 to 240 V. The M80A runs on 110 V only and has a stainless steel housing.
The Rancilio grinds with 64 mm flat steel burrs at 1350 rpm and uses a manual dosing lever. The maker rates its output at 1.9 to 2.5 g/s. It weighs 28.7 lb (13 kg), and a US dealer lists its noise under 70 dB.
US dealers list the Rancilio between $1,615 and $2,200, well above the $1,389 M80A.
The Astra MG053 sits between the two. It draws 350 W, has a 3.3 lb (1.5 kg) hopper, turns at 1400 rpm and runs on 120 V. It uses 64 mm flat burrs and costs $1,439.90 at KaTom, $51 above the M80A.
Who Should Avoid the Ampto M80A?
Buyers who need timed doses should avoid the Ampto M80A because the grinder has no timer. The M80E covers that need.
Single-dose home users form another group. A doser chute holds ground coffee, and a bench test of the Quamar M80 found its adjustment not precise enough for single dosing. The Niche Zero, a 63 mm conical single-dose grinder, costs $599 to $649 in the US.
Shops that serve decaf or a second blend form another group. The M80A has one hopper and one chute, so each bean swap means emptying both. Grounds left in a doser chute go stale between uses.
Buyers outside the US also avoid the M80A. The grinder runs on 110 V, 60 Hz and the warranty covers the US only.
Small counters form another group. The grinder stands 23 in (58 cm) tall and weighs 29 lb (13 kg).
Buyers who need outside proof of grind quality also wait. No independent test of the M80A exists.
Buyers who avoid the M80A:
- Buyers who need timed doses
- Single-dose home users
- Shops that serve decaf or a second blend
- Buyers outside the US
- Shops with small counters
Is the Ampto M80A Good for Home Use?
No. The Ampto M80A is built for commercial service, not for home use. The price is $1,389.
Rated output is 7.7 lb/hr (3.5 kg/hr), a rate set for cafe counters. A household uses only a fraction of that.
A bench test of the Quamar M80 reached a similar verdict: better suited to commercial use than to home users. The tester saw a home role mainly for single dosing.
How Much Does the Ampto M80A Cost?
The Ampto M80A costs $1,389.00 at several US dealers. That price sits 44% below a listed retail price of $2,496. The markdown equals $1,107.
Kitchenall, ChefsDeal and Pizza Ovens each show the same $1,389.00. The $2,496 figure is the retail price printed on dealer pages, not a price buyers pay.
The M80E costs $1,575.00 at TigerChef. That is $186 above the M80A.
Running cost is small. A 300 W motor draws 0.3 kW, so one hour of nonstop grinding uses 0.3 kWh.
Is the Ampto M80A Worth the Price?
Yes. The Ampto M80A is worth the price to a small shop that wants an Italian-built doser grinder under $1,400. The $1,389 price buys 63 mm flat burrs and a dose counter.
A doser grinder holds ground coffee in a chamber and releases it in set amounts. The dose counter on the M80A tracks those releases. The M80E costs $186 more and adds a timer, so buyers who want timed doses spend that extra.
Rival prices show how the M80A compares. The Mazzer Super Jolly costs $1,095. The Astra MG053 costs $1,439.90. The Rancilio Kryo EVO 65 AT costs $1,615 to $2,200. The M80A sits second from the bottom of that list.
US Prices:
| Grinder | Price |
|---|---|
| Mazzer Super Jolly | $1,095 |
| Ampto M80A | $1,389 |
| Ampto M80E | $1,575 |
| Astra MG053 | $1,439.90 |
| Rancilio Kryo EVO 65 AT | $1,615 to $2,200 |
No outside test ranks the M80A on grind quality, so the value case rests on the 63 mm flat burrs and the dose counter.
What Warranty Covers the Ampto M80A?
The Ampto M80A warranty covers parts for 1 year and labor for 1 year, in the US only.
Ampto backs this coverage with three documents for the M80A: a spec sheet, a user manual and a warranty sheet.
A vendor of the related Quamar M80E says its warranty does not cover burrs. Dealer summaries of the M80A do not say whether its burrs are covered.
Is the Ampto M80A Worth It?
Yes. The Ampto M80A is worth it for a small cafe that wants an Italian-built doser grinder at $1,389.
Buyers who want a timer take the M80E at $1,575. Buyers who want more power and a bigger hopper look at the Rancilio Kryo EVO 65.
The Mazzer Super Jolly costs $294 less and carries a 2 year parts and labor warranty, so the Super Jolly is the first rival to check. The Niche Zero suits home buyers at $599 to $649.
No owner reviews or independent tests of the M80A exist, so the verdict rests on specs, a sibling bench test and dealer prices.
What Are the Ampto M80A Pros and Cons?
The Ampto M80A pros are its Italian build, 63 mm flat burrs and dose counter, and its cons are the missing timer and the missing test data.
The grinder is built in Italy, and its housing is metal. It also carries the ETL Sanitation certification. A 1 year warranty covers the unit.
Grinding quality depends on the burrs, the parts that crush the beans. The M80A uses 63 mm flat burrs, and a dose counter tracks how much coffee the grinder has made.
The weaknesses start with the controls. The grinder has no timer, so the user cannot set a grind time. The motor is 300 W, which trails rivals. Dealers also list conflicting specs, and no independent tests exist to settle the question.
The size adds a practical limit. The grinder stands 23 in (58 cm) tall and weighs 29 lb (13 kg).
Pros:
- Italian build
- 63 mm flat burrs
- Dose counter
- Metal housing
- ETL Sanitation certification
Cons:
- No timer
- 300 W motor
- No independent tests
- Conflicting dealer specs
- 23 in (58 cm) height
