Powering Hundreds of Businesses Including:

The Kony S is a medium-to-high-volume commercial espresso grinder for bars that want the body and low-speed operation of conical burrs without giving up an on-demand workflow. Its 63 mm burr set, 500 RPM speed at 60 Hz, and dual-fan cooling are designed to keep grinding behavior stable through a rush.

Product Features

Three Timed Doses + Manual

Three programmable time-based doses, manual grinding, and a pause function let baristas build repeatable recipes while retaining control for top-ups and unusual baskets.

63 mm Conical Burrs

Mazzer’s 63 mm hardened-steel conical burrs deliver about 3.6 g/s at 60 Hz while turning at a low 500 RPM, balancing strong espresso throughput with controlled heat.

Grind Flow Control

The removable GFC outlet insert uses a wire damper to reduce clumping, static, and counter mess while directing grounds cleanly into the portafilter.

Memory Track Adjustment

Stepless micrometric adjustment provides fine espresso control, while Mazzer’s Memory Track scale makes settings easier to index and return to after a change.

Dual-Fan Cooling

Two electronically controlled fans help manage motor and grinding-chamber temperature during sustained commercial use.

Hands-Free Portafilter Activation

An adjustable portafilter holder centers the basket under the chute and activates grinding for a hands-free on-demand workflow.

The Coffeeionado Take

Who's It For:

  • Medium- to high-volume cafés using the Kony S as a primary espresso grinder.
  • Restaurants, bakeries, and hospitality bars that need repeatable timed dosing with commercial durability.
  • Specialty programs that prefer the texture and low-speed operation of a conical burr set.

It's Right For You If:

  • You need a primary espresso grinder for a steady one- or two-group café, with enough headroom for demanding rush periods.
  • You prefer low-RPM conical grinding and want programmable time-based doses, hands-free activation, and active cooling.

Things to Consider:

  • Dosing is time-based, not grind-by-weight; use a scale when gram-level dose verification is required.
  • The full-size 1.3 kg hopper and roughly 20 kg body require a permanent commercial counter position.
  • This grinder is optimized for espresso rather than frequent switching among espresso and filter recipes.

Our Take:

The Kony S is a strong fit when a café wants conical-burr character and excellent thermal behavior in a grinder that can still move quickly. It is especially compelling as a primary grinder for a one- or two-group bar, or as a high-capacity second grinder in a larger program.

Commercial Workflow

Three programmable timed doses, manual grinding, a pause function, and an adjustable hands-free portafilter holder support fast bar work.

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 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 90 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 the customer's 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 the customer's 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 the customer's 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 the customer's responsibility.

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

What to Expect on Install Day

Getting a commercial espresso machine delivered is one thing. Getting it actually running — plumbed, programmed, and pulling properly — is another. Here's what happens when the technician comes out.

Before the appointment: Site preparation will be confirmed before technicians make it out. Once your machine ships, we'll coordinate scheduling with you and assign a local certified technician. Before they arrive, make sure your space is ready: the machine's permanent location should be determined, your water line and drain access should be in place, and your electrical supply should match the machine's requirements. 

On the day The technician will handle the physical installation of the machine — positioning, water line connection, and drain setup. Once it's plumbed and powered, they'll run through the setup and basic programming: boiler pressure, shot parameters, and confirming that water flows correctly through the group heads and steam wands. Some basic training will be provided, they'll pull test shots to verify the machine is operating within spec.

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.
