Powering Hundreds of Businesses Including:

Investing in a Kony S is a quiet acknowledgment that you’ve moved past the hobbyist phase and are now building a professional-grade station. At this level, you aren't just looking for a grind; you’re looking for the specific, textured clarity that only 63 mm conical burrs provide under a consistent thermal load. The integrated Memory Track System is a nod to the fact that you have better things to do than recalibrate your zero point every time you perform routine maintenance. It is the tool that finally allows you to focus on the coffee rather than the limitations of the equipment.

Product Features

Stepless Micrometrical Adjustment

Fine-tune grind size with stepless micrometrical control for repeatable espresso dialing across different beans and roasts. This precision adjustment lets baristas lock in a target particle size without being limited to preset detents.

User-Friendly Memory Track System

Easily index and recall grind settings to speed operator changeovers and keep recipes consistent across shifts. The Memory Track System gives a broader, more precise adjustment range so staff can return reliably to a specific setting during busy service.

63 mm Conical Burrs

Italian-made 63 mm conical burrs deliver low retention and a consistent particle distribution that works well across espresso and filter ranges. The large, precision-machined steel burrs help maintain dose accuracy and even extraction through thousands of shots.

Commercial-Grade Motor

High-torque commercial motor is built to handle continuous service without heat buildup, ensuring consistent particle size over a full day. Specs include 450 Watts of power and burr speeds of 400 RPM (50Hz) / 500 RPM (60Hz) for stable, reliable grinding under sustained load.

Double Fan Cooling System

Dual fans keep the hopper and burr chamber cooler during heavy use to preserve bean aroma and prevent heat transfer to the grind. The cooling system helps maintain flavor integrity when producing high volumes of shots.

Grind Flow Control (GFC) System

The GFC system reduces electrostatic charge and evens out grounds distribution with a removable aluminum outlet insert and wire damper, improving dose consistency into the portafilter. Combined with the adjustable portafilter holder and on-demand activation, it centers flow for cleaner, more repeatable dosing.

The Coffeeionado Take

Who's It For:

  • Home Baristas Ready to Step Up — If your current grinder is holding back your espresso, the 63mm conical steel burrs and stepless micrometric adjustment offer the precision to actually taste the difference
  • Small Offices & Light Commercial Use — At 3.6 g/sec, this grinder handles a busy morning rush for a small office or low-volume café without breaking a sweat
  • Italian-Made Purists — Manufactured in Italy with the build quality that implies. For those who value proven engineering pedigree

It's Right For You If:

  • You're looking for a capable home grinder with stepless micrometric adjustment that lets you fine-tune your espresso without the compromises of stepped settings.
  • The low 500 RPM motor keeps bean temperature down during grinding, preserving volatile aromatics that high-speed grinders can cook off.

Things to Consider:

  • At 20.0kg, this grinder is heavier than most prosumer equipment. It's built like commercial gear because, in many ways, it is.
  • Like any flat burr grinder, you'll want to run a small purge between grind setting changes to clear retained particles from the burr chamber.

Our Take:

The Mazzer Kony S Electric Espresso Grinder is a well-built prosumer grinder with 63mm conical steel burrs that punch above their size class. A solid choice for home baristas who want café-quality espresso without café-sized equipment.

Stepless Grinder

The Kony S features micrometric stepless grinding adjustments and a chrome plated fork rest. The new adjustment collar also allows for easy, accessible cleaning of the grinding chamber without losing the last saved grind setting.

Stepless grinders differ from stepped grinders in that they do not have preset grind settings; instead, they feature a collar that you can rotate to adjust the grind size. This collar is usually marked with incremental lines or notches, providing a way to monitor the grind size.

Kony S screen

Easily Programmable

It also comes with programmable controls and a doser funnel for your grounds. The controls allow you to program your shots, you can set up 3 different shots and pulse when needed. It also comes with the added pause function, in case you need to tend to something mid-grind. It can give you a 20 gram shot in a little under 5 seconds.

Grind Flow Control System

The Kony S features a new Grind Flow Control System. It consists of two aluminum wire dampers and guarantees clump-free grounds regardless of coffee variables or weather.

Cool Grinding

This commercial coffee grinder features 2 cooling fans to ensure a cool chamber. Mazzer placed 63 mm conical burrs in this coffee grinder which the burrs to grind with added torque while keeping cool and producing very consistent results. It is definitely just as fast though. It's 63 mm steel conical burrs allow it speed through 4 grams per second while keeping the beans nice and cool at 450 rpms.

Dual Fan Cooling System

The dual fan cooling system is an essential component of coffee grinders, as it plays a vital role in maintaining performance and preserving coffee quality. Here's why it's important:

  1. Heat Reduction: Coffee grinding creates heat through the friction between the burrs and beans, which can negatively impact the flavor and aroma of the coffee. The dual fan system actively dissipates this heat to prevent the grounds from overheating during grinding.
  2. Consistent Extraction: Heat can affect the extraction process, causing premature release of volatile compounds from hot coffee grounds and leading to uneven extraction. The dual fan system maintains a consistent temperature to ensure balanced flavors in espresso shots.
  3. Shot Time Stability: In busy cafes, consistent shot times are crucial, but heat buildup can cause variations in grind particle size and extraction times. The dual fan cooling system minimizes these fluctuations, allowing baristas to maintain precise shot times even during peak hours.
  4. Reduced Recalibration: Grinders without proper cooling may require frequent recalibration due to temperature-induced changes in grind consistency. The dual fan system helps stabilize grind settings, reducing the need for constant adjustments.
  5. Longevity: Excessive heat can accelerate wear and tear on grinder components, but the dual fan cooling system helps maintain a lower temperature to contribute to the grinder's longevity.

Sturdy and Durable

It is an affordable option and features a diecast aluminum frame. It will give any medium sized cafe the consistent quality grinds they demand. If you're putting out 60-100 shots a day and are not needing the capabilities of the Robur then this is your grinder. Its shear durability makes it a prime choice when it comes to any brew bar.

63mm Conical Burrs

Conical burrs are designed in a cone shape, with one section rotating inside a stationary ring-shaped burr. Coffee beans are fed from above and crushed between these two parts, with gravity and angled edges guiding the coffee downward.

The benefits of conical burr grinders include reduced heat production during grinding, maintaining the delicate flavors of the coffee beans. They are also cost-effective compared to flat burrs, operate quietly at lower speeds, and require less power due to their pre-breaker teeth. Conical burrs excel at producing rich flavor profiles and full-bodied cups of coffee.

Grind Flow Control

Prevent coffee grounds from spilling onto the countertop and ensure consistent coffee grounds in your portafilter with the revolutionary GFC System. The GFC (Grind Flow Control) features a detachable aluminum outlet insert that includes a wire damper for smooth and controlled flow.

Internet Connected Grinder

Stay connected to your grinder through the cloud, no matter where you are. With an internet-enabled platform, you can remotely access data about your grinder. Monitor its output and stay on top of maintenance requirements with ease.

What We'd Tell You In Store

How to Choose a Commercial Espresso Machine

How to choose a commercial espresso machine based on real volume numbers, peak hour output, and drink mix — not vague categories.

How to Choose a Commercial Grinder

Your espresso machine gets all the attention. The grinder does all the work. Every variable that determines shot quality — particle size, extraction evenness, dose consistency — starts at the grinder.

How to Design Your Cafe: Build Your Bar for the Rush

Design your café bar for peak volume, not average traffic. Equipment layout, station design, staffing ratios, and tools that remove steps — what actually matters during the rush.

Setting Up Your Commercial Espresso Machine Right

Water pressure, electrical specs, drain slope, filter flushing — what actually goes into a commercial espresso machine setup, and what gets skipped.

Product FAQ

What type and size of burrs does the Mazzer Kony S Electric Espresso Grinder use?

The Mazzer Kony S Electric uses large conical burrs (63 mm, depending on the specific Kony S configuration) designed specifically for espresso. Conical burrs tend to produce lower heat and excellent particle consistency, which helps with flavor clarity and shot repeatability in both home and commercial environments.

Is the Mazzer Kony S a stepless grinder, and how precise are the grind adjustments?

Yes. The Kony S is a stepless grinder, meaning grind size is adjusted continuously rather than in fixed clicks. This allows very fine, precise adjustments to dial in your espresso, which is essential for getting the best results across different coffees and recipes.

Is the Mazzer Kony S suitable for both home and commercial settings like cafés or restaurants?

The Kony S is designed as a commercial-grade espresso grinder but is also used by serious home enthusiasts. Its high build quality, conical burrs, and powerful motor make it well-suited for busy coffee bars, restaurants, and prosumer home setups that want café-level performance.

Does the Mazzer Kony S grind only for espresso, or can it also be used for filter coffee and other brew methods?

The Kony S is optimized for espresso and excels in the fine range. It can technically be adjusted coarser for methods like moka pot or some filter brews, but it is not a dedicated multi-purpose grinder. If you need frequent switching between espresso and filter, a grinder specifically designed for multi-brew use may be more convenient.

How often do I need to replace the burrs on the Mazzer Kony S, and how long do they typically last?

Burr life depends heavily on volume and bean hardness. For typical commercial use, Mazzer conical burrs are often rated for several hundred kilograms of coffee before replacement is recommended. In a high-volume café, this might mean replacement every 1–2 years; in a home or low-volume setting, burrs can last many years. You’ll know it’s time when grind consistency drops, shots become harder to dial in, or you need to grind finer than usual for the same extraction.

Will the Mazzer Kony S fit under standard kitchen cabinets?

The Kony S is a tall commercial-style grinder. With its hopper installed, it is typically taller than standard 18-inch under-cabinet clearances in many U.S. kitchens. Many home users either place it in a spot without overhead cabinets or use a shorter aftermarket hopper to fit under cabinets. Check the exact height in the specifications and measure your space before purchasing.

Does the Mazzer Kony S support hands-free grinding, and how does the portafilter holder work?

Yes. The Kony S includes an adjustable portafilter fork/holder so you can lock in most commercial-style portafilters and grind hands-free directly into the basket. This helps streamline workflow in busy environments and reduces the need to hold the portafilter during grinding.

Does the Mazzer Kony S offer timed or manual dosing, and can I program multiple doses?

The Kony S is a doserless, on-demand grinder with electronic controls. It typically offers programmable timed dosing (for example, single and double shot profiles) and may also have a manual dose mode for topping up or custom doses. You adjust dose time via the control panel to match your target dose by weight using a separate scale.

How does free installation work?

We want to make your purchase as smooth as possible and will pay the installation via rebate on commercial espresso machines. This includes commercial machines with more than 1 group head and 220V.

If the certified installer needed is over 1.5 hours away then we will pay for the installation call (and install up to the value suggested on page minus call fee). Travel will be paid by customer. Inquire if you have any questions about your location.


Please note, any discounts subject to void the paid installation offer.

At Coffeeionado, professional installation is included with qualifying espresso machine purchases. Our goal is to make the process as seamless as possible — from coordinating the technician to getting your machine up and running on day one.

Which Machines Qualify

Free professional installation is included with all espresso machines of 2 groups or more where indicated on the product listing. This policy applies to espresso machines only and does not cover other coffee equipment such as grinders, brewers, or accessories.

If you are unsure whether your machine qualifies, contact us before purchasing and we'll confirm.

What's Included

  • Travel and labor costs for installation within the technician's service area (up to 2 hours of travel)
  • Setup, basic programming, and commissioning of the equipment
  • Scheduling during regular business hours, Monday through Friday
  • Associated taxes and fees related to the installation itself

Installation must be completed within 30 days of delivery of the equipment. The installation benefit lapses after this window and cannot be reinstated.

How Installation Is Arranged

Depending on your purchase, installation is handled one of two ways:

Arranged directly — In many cases, Coffeeionado or the manufacturer will coordinate and pay the technician on your behalf. We will contact you after your order is processed to schedule the visit.

Reimbursement — In some cases, you may be asked to arrange the installation locally using an authorized technician and submit a rebate form for reimbursement. Once approved, the covered amount will be refunded to the original payment method used for your order.

We will confirm which arrangement applies to your purchase at the time of order confirmation. If you have questions before purchasing, contact us and we'll walk you through it.

What's Not Included

The following are outside the scope of the installation policy and remain the customer's responsibility:

  • Travel or callout costs beyond the first 2 hours of the technician's travel time — if your location falls outside the local service area, the overage is your responsibility
  • Water filtration systems and installation materials — including plumbing fittings, tubing, plugs, outlets, and any other ancillary components required to prepare the site
  • Electrical or plumbing work — site preparation must be completed before the technician arrives
  • Training on equipment operation — installation covers commissioning only, not barista or operational training
  • False start or callout fees if the technician arrives and the site is not ready for installation

Important: If a technician arrives and cannot complete the installation because the site is unprepared, you will be responsible for any callout or false start fee charged by the technician. However, your installation benefit remains intact — the visit will be rescheduled at no additional cost to your policy.

Water Filtration Requirement

Water filtration must be installed and operational before or at the time of installation. This is not optional — operating a commercial espresso machine without proper filtration will void the manufacturer's warranty. If filtration is not in place at the time of the technician's visit, installation may need to be rescheduled and the callout fee will be your responsibility.

If you need guidance on water filtration requirements for your machine, contact us before scheduling your installation.

Service Area

Installation coverage is tied to the manufacturer's authorized technician service area, generally within a 1.5-hour radius of the nearest certified technician. If your location falls outside this area, Coffeeionado will make reasonable efforts to arrange a local authorized technician, but travel costs beyond the 2-hour coverage limit remain your responsibility.

Not sure if you're in a service area? Contact us before purchasing and we'll check your location.

After Installation

Once your machine is installed, we'll provide referrals for authorized service technicians in your area for ongoing maintenance and repairs. Coffeeionado offers lifetime support on all equipment we sell — we're here long after the install is done.

Governing Terms

This installation policy forms part of your agreement with Coffeeionado and is subject to our Terms of Sale and Terms of Service. In the event of any conflict, the Terms of Service governs.

Can I pick up the machine at your store?

We do not have a showroom or storefront for customer pickups, so orders cannot be picked up directly from us. That said, there is an exception for La Spaziale and La Pavoni products, you can contact us to arrange.

However, if you'd prefer, we can arrange to have your machine shipped to a local freight terminal/location for pickup instead. Let us know your city/state (or ZIP code), and we’d be happy to check the nearest terminal options for you.
