Quamar Coffee Grinders: Complete Model Guide

Quamar’s Italian catalog stretches from compact home-capable on-demand grinders to 75 and 83 mm commercial platforms. Similar suffixes—E, Touch and Touch Plus—describe controls and dosing, while the base model identifies the mechanical family.

Editorial note: Espresso Outlet does not sell Quamar grinders. Model status and specifications reflect official information reviewed in September 2026; confirm voltage, burr option and regional support before purchasing.

Quamar alternatives at a glance

Quamar history

Quamar is an Italian food-equipment manufacturer based in Altivole in the Veneto region, an area with deep commercial espresso-equipment expertise. The company builds grinders and related bar equipment for international hospitality markets.

Its current catalog combines long-running models such as Q50 and M80 with newer Q13, Nemo-Q and premium Sirio-Q platforms. Hopper and plug options create many regional configurations without necessarily creating new mechanical models.

Current and documented Quamar grinder models

Q50 E and T48

These are the easiest Quamar families to consider for lower-volume settings. Q50 E is widely documented with a 54 mm flat-burr class and electronic dosing. T48 occupies a similarly compact role with updated controls. Hopper choices may include small 150/250 gram formats, but a small hopper is not identical to a low-retention single-dose chamber.

M80 and Q13

M80 versions differ principally in control system—E, Touch and Touch Plus—while Q13 moves to 75 mm flat burrs for higher throughput. Quamar lists Q13 as suitable for substantial daily volume. Buyers should still validate rush-hour demand rather than using a daily-kilogram claim as the only sizing metric.

Nemo-Q and Sirio-Q

Nemo-Q updates the midrange commercial presentation, while Sirio-Q is the premium flagship. Touchscreen features can simplify programming, but burr replacement, thermal behavior, cleaning access and distributor service determine long-term café value.

How to compare Quamar with Espresso Outlet grinders

For home timed dosing, Eureka Mignon Specialita is the clearest alternative. For commercial work, compare M80/Q13/Nemo/Sirio with Ceado E37S and Fiorenzato F64 EVO PRO, using real hourly shot volume, burr replacement cost and service support.

• Match the burr geometry to the cup. Diameter alone does not predict clarity, texture or sweetness.
• Decide between hopper and single-dose use. Retention and bean switching matter as much as speed at home.
• Separate convenience from measurement. Timed dosing estimates mass; grind-by-weight actually measures it.
• Confirm serviceability. Burrs, electronics, calibration instructions and regional support affect long-term value.

Quamar grinder FAQs

What do E, Touch and Touch Plus mean?

They generally identify electronic interface and dosing variations within a mechanical family.

What size burrs does Q13 use?

Quamar specifies 75 mm flat burrs for current Q13/E and Touch Plus configurations.

Can Quamar grinders use a small hopper?

Quamar offers 150, 250, 500, 1200 and 1500 gram choices for certain models; compatibility varies.

Is a 150 gram hopper truly single dose?

No. It reduces stored-bean capacity but does not automatically change internal retention or feed design.

Which Quamar is best for a busy café?

Q13 and Sirio-Q are the natural high-output candidates, but the correct model depends on hourly demand, roast, menu and service support.

Is Q20 a coffee grinder?

Quamar Q20 references commonly describe portafilter-cleaning equipment, not a grinder, so it is excluded from this grinder directory.

Engineering deep dive: what matters beyond the spec sheet

Quamar’s catalog is organized around mechanical families and interface suffixes. Q50 and T48 occupy compact roles, M80 is a long-running mid-size commercial platform, Q13 steps to roughly 75 mm flats, and Nemo-Q and Sirio-Q represent newer industrial design. E, Touch and Touch Plus usually describe controls rather than a wholly different burr system.

Commercial Quamar grinders use fine micrometric adjustment because espresso shifts demand small corrections. Some collars are continuous and some revisions use updated mechanisms. Baristas should record direction and movement relative to a reference mark, not copy a number from another unit.

Q50 is commonly documented in the 54 mm class; M80 around 63 mm; Q13 around 75 mm. Sirio-Q specifications must be checked for the exact version. Larger burrs can increase grams per second, but motor power, cooling, duty cycle and geometry decide rush-hour performance.

Model-by-model buying analysis

Q50 E and compact Q50 variants

Q50 is the entry into Quamar’s professional on-demand style, with electronic doses and small-hopper options that can work in a home or low-volume bar.

It is slower than larger café models and retains coffee like a traditional hopper grinder. Compare its workflow with Eureka Specialita rather than a single-dose machine.

T48

T48 updates the compact category with touch-oriented controls and a modern case. It targets on-demand espresso where counter width matters.

Confirm burr diameter and interface for the exact regional model; T48 naming should not be expanded into invented suffixes.

M80 E, Touch and Touch Plus

M80 is Quamar’s familiar mid-size platform. Interface suffixes change programming, display and barista interaction while the core grinder remains in a similar burr class.

For a busy shop, calculate drinks during the rush rather than daily totals. M80 may be sufficient for moderate service but can become the bottleneck during back-to-back doubles.

Q13 E and Q13 Touch Plus

Q13’s approximately 75 mm flat burrs increase speed and place it firmly in commercial use. Touch Plus adds richer programming and display behavior.

Its hopper, fan behavior and electrical specification should be selected for the installation. Compare with Ceado E37S and Fiorenzato F64 EVO PRO on actual dose time and service.

Nemo-Q

Nemo-Q applies Quamar’s newer design language to electronic on-demand grinding. Exact position and specifications can vary as the catalog evolves.

Request the current technical sheet instead of copying an older distributor page. Pay attention to burr set, motor, hopper options and menu version.

Sirio-Q

Sirio-Q is a flagship commercial platform intended for higher speed and premium bar presentation.

Its value depends on throughput, consistency under heat and local parts support. A café should test representative coffee at rush volume, not choose solely by its larger appearance.

How to compare Quamar fairly

Quamar comparisons require the café’s volume and workflow. Q50/T48 align with compact Eureka; M80 and Q13 with Ceado or Fiorenzato commercial grinders; Sirio-Q should be evaluated against the exact high-output machine rather than a generic 64 mm home model.

A measurement-led grinder test

Marketing terms such as “zero retention,” “commercial grade” and “espresso capable” are not standardized. Test a grinder with a repeatable protocol. First weigh a dose to 0.1 gram, grind at the intended setting and weigh the output. Repeat five times without changing anything. The difference between input and output estimates immediate retention; the spread among outputs reveals dosing repeatability. This is not a laboratory retention test because old coffee may exchange with new coffee, but it exposes the behavior a home user experiences.

Next, make three espresso shots with a fixed dose and beverage yield. Record grind setting, time to first drip, total shot time and taste. A useful espresso adjustment should let you move gradually from too fast to balanced to too slow without one control step skipping the workable zone. For filter coffee, hold brewer, paper, water, dose and pouring pattern constant. Record drawdown and taste at three nearby settings. The best grinder is the one that makes intentional corrections easy, not necessarily the one with the largest burr number.

Test workflow separately from cup quality. Time bean loading, grinding, transfer, distribution and cleanup. Note whether the hopper can be closed, whether the fork fits your portafilter, whether the grounds cup creates static and whether controls can be operated before coffee. A machine can produce excellent grounds yet frustrate its owner every morning; another can be pleasant but lack the adjustment needed for the recipe.

Dialing in Quamar: practical guidance

Dial commercial models with the hopper at a representative level, because bean weight can influence feed. Purge after every collar move and measure at least three doses before reprogramming buttons.

Program dose by weight, then translate to time. Check the first morning dose separately because retained coffee and cool components can behave differently from steady service.

During a rush, watch shot trend and grinder temperature. Correct gradually. Large reactive collar moves can create alternating fast and slow shots as retained coffee clears.

Retention, static and exchange

Q50, M80, Q13 and Sirio-Q are designed for on-demand continuity, not empty-chamber single dosing. Their retained bed can stabilize feed, but decaf and origin changes require planned purging. Cafés should include purge loss in cost calculations.

Retention and exchange are related but different. Retention is coffee left inside after grinding; exchange is old coffee displaced by the next dose. A grinder can show nearly equal input and output while still exchanging stale grounds. To check, grind a dark coffee, clean the visible exit, then run a light coffee and inspect the first output. Large color mixing indicates exchange that matters when alternating regular and decaf or changing expensive coffees.

Service, warranty and long-term ownership

Commercial value depends heavily on the distributor. Confirm who stocks burrs, fans, touchscreens, portafilter forks, hoppers and boards and whether a local technician has worked on the chosen generation.

Clean the chute and burr chamber on a schedule tied to kilograms ground. A cooling fan cannot compensate for clogged vents. Record burr-install dates and cumulative volume so replacement is proactive.

Before importing, verify voltage, frequency, plug, local certification and who pays international freight for warranty work. Burr diameter alone does not identify a replacement: mounting holes, thickness, rotation direction and cutting geometry must match. Electronic displays, control boards, power supplies and proprietary forks can determine whether an older grinder is economical to repair.

Expanded Quamar FAQs

Where are Quamar grinders made?

Quamar is an Italian manufacturer based in the Veneto region and supplies grinders and bar equipment internationally.

What do E, Touch and Touch Plus mean?

They generally distinguish electronic interfaces and programming levels within a base mechanical family. Exact functions vary by model.

What burrs are in Q50?

Q50 models are commonly documented with flat burrs in the roughly 54 mm class. Verify the exact technical sheet before ordering replacements.

How large are M80 burrs?

The M80 family is commonly associated with approximately 63 mm flat burrs, subject to version-specific confirmation.

Is Q13 for home use?

It can physically be used at home, but its size, hopper, retention and commercial workflow make sense primarily for cafés or very high-volume enthusiasts.

Can Quamar grinders single-dose?

Beans can be loaded individually, but the main models are traditional hopper on-demand designs. Output exchange will exceed a purpose-built single doser.

Q50 or Eureka Specialita?

Both target compact timed espresso. Compare fine adjustment, dose controls, noise, dimensions and local parts support.

Q13 or Ceado E37S?

Test dose speed, heat, clumping, controls and service with your coffee. Burr diameter alone cannot decide.

How often should commercial burrs be changed?

Follow Quamar’s rated-volume guidance for the exact burrs and monitor speed and extraction. Track kilograms rather than relying on calendar time.

Why does a programmed dose drift?

Bean density, grind, hopper level, humidity and chute condition change grams per second. Reweigh throughout the day.

Who should buy—and who should skip—Quamar

Buy Quamar when an authorized local channel supports the exact model and its measured throughput fits the bar. The catalog offers a logical progression from compact Q50/T48 through M80 and Q13 to premium platforms.

Skip or reconsider when the purchase is an unsupported import, the interface suffix is unclear or the café has not measured rush demand. A better-supported Ceado or Fiorenzato can be the safer business decision even when specifications look similar.

Quamar buyer worksheet: choosing with fewer surprises

A 70-drink café may be well served by M80 if its busiest fifteen minutes are moderate; a 200-drink bar with concentrated morning demand should test Q13 or Sirio-Q at real double-shot cadence. Q50 and T48 can work in a home or decaf station. Daily totals conceal the rush, which is when grind time and recovery determine whether a grinder fits.

Write the recipe before choosing the grinder

List the drinks made during the busiest fifteen minutes, not merely a daily total. Record basket type, normal dose, roast style, whether regular and decaf alternate, and the coarsest brew method used. A grinder for two weekend pour-overs has different motor, hopper and service needs from one preparing six double shots in ten minutes. This worksheet prevents an attractive feature from replacing the actual requirement.

Separate cup goals from workflow goals

For cup style, decide whether the priority is heavy traditional espresso, clarity and flavor separation, forgiving milk drinks or broad filter use. For workflow, decide between a stored hopper, weighed single doses, a timer, grind by weight or manual power. Burr geometry influences flavor, but a workflow that causes stale beans, wasted purge coffee or skipped weighing can overwhelm small theoretical differences.

Calculate total ownership cost

Add the grinder price, tax, shipping, currency conversion, burr option, required scale, portafilter fork or dosing cup, transformer if one is legitimately approved, and likely return freight. Then price one set of burrs and the most expensive plausible electronic part. A direct-sale grinder can be excellent while still costing more to support than its checkout price suggests. A used grinder can be poor value if a missing hopper or board is unobtainable.

Used-market inspection for Quamar

Request the base model and interface suffix, serial, voltage and burr-install date. Test every dose button, display and fork switch. Check vents for packed coffee and listen for fan operation where fitted. A Touch Plus board or proprietary display can cost far more than a standard burr replacement.

Questions to ask the seller

• What is the complete model, suffix, serial number, voltage and frequency?
• Which burr is installed, when was it installed and approximately how much coffee has it ground?
• Is the seller authorized, and who performs warranty work in the buyer’s country?
• Are hopper, lid, grounds cup, fork, tools, power supply, manual and original packaging included?
• Can the seller provide a continuous video showing startup, adjustment, grinding under beans and every electronic function?

Red flags that outweigh a discount

Walk away from a grinder with an unreadable rating plate, electrical modifications, bypassed safety switch, intermittent motor, scraping burrs far from zero, cracked carrier, swollen battery, missing proprietary power supply or seller refusal to show operation. Cosmetic marks can be acceptable; uncertainty around alignment, mains power or unavailable electronics is not.

Understanding warranty, voltage and regional listings

A manufacturer warranty is usually tied to an authorized region and seller. Importing can transfer freight and customs responsibility to the owner even when the defect itself is covered. Ask in writing who supplies parts, who approves a repair and where the machine must ship. Save the invoice, serial photograph and packaging.

North American residential circuits normally supply about 120 volts at 60 hertz, while many European grinders are designed for 220–240 volts at 50 hertz. A shape-changing plug adapter does not convert either value. Transformers add capacity, grounding and certification questions and can affect motors or electronics. The safest purchase is a factory configuration intended for the installation.

How to read reviews of Quamar grinders

Confirm that a review covers the same generation, burr, firmware and voltage. Note the coffee, roast, brew method and basket. A reviewer making light-roast turbo shots with a clarity burr is not directly answering whether a traditional dark blend will produce heavy ristretto. Likewise, a café test does not establish how pleasant a grinder is when single-dosed once each morning.

Give more weight to measured dose variation, grind time, setting response, retention protocol and long-term service history than to unqualified adjectives. Taste reports are valuable when the recipe and comparison grinder are disclosed. Early review units, prototypes and crowdfunding targets should be labeled as such; current manuals and shipping product pages override them.

Final perspective

Quamar should be shopped by mechanical family first and screen suffix second; Q50/T48 serve compact needs, M80/Nemo the middle, and Q13/Sirio higher-volume bars. Compare more choices in our home grinder and commercial grinder collections.
