The Mazzer Kold Electronic S Black Coffee Grinder is a high-performance espresso grinder designed for high-volume cafés and specialty coffee venues. With its 71mm conical burrs and low-RPM operation, this grinder ensures uniform particle distribution while preserving the coffee’s flavour and aroma, even during peak service times. The built-in IoT functionality allows for remote access to real-time grind reports, making it easy to monitor output and track maintenance needs.
The Mazzer Kold S Electronic is a high-performance espresso grinder and one of the fastest models in the Mazzer S line, alongside the Robur S. Hand-built in Venice, Italy, the Kold S is engineered for high-volume cafés, roasteries, and specialty coffee venues that refuse to compromise on grind quality during peak service. It features 71mm conical burrs driven by a low-RPM belt-driven transmission and a double cooling fan system — a thermal architecture purpose-built to keep the grinding chamber cool, preserve aroma, and protect coffee from heat exposure even through extended grinding sessions.
The Kold S construction is engineered specifically to protect the coffee from heat. The motor is mechanically isolated from the grinding chamber via belt-driven transmission, the burrs run at low RPM, and a double fan cooling system actively dissipates heat — meaning your coffee retains its full aromatic profile from the first shot of the morning through the busiest afternoon rush. The Electronic version features a touch display with three programmable buttons for different dose amounts, plus a fourth manual button for precise fine tuning of the dose.
Built-in IoT functionality lets baristas, roasters, owners, and service technicians remotely access real-time grind reports via the cloud — for monitoring output, tracking usage, and staying ahead of maintenance needs. A portafilter-activated grinding button on the fully adjustable portafilter holder enables hands-free operation, while the Grind Flow Control (GFC) system reduces clumping and powder build-up. For the operator who runs a serious coffee program and wants the most thermally optimised conical-burr grinder Mazzer makes, the Kold S Electronic is a true investment piece.

Had my ECM Synchronika serviced by Espresso Works recently and figured the service was worth writing a review of my excellent experience. I bought my machine second hand and immediately encountered a leak from my flow control valve. Another 5-star rated company charged me an absolute fortune and didn't resolve the issue until the second visit. I had to show them how to fix the leak, and that it was two perished o-rings that caused it. The fix only requires 10 minutes of work and a few dollars in parts. They also returned my machine with a dent and several scratches. The reason I include this anecdote is because it doesn't seem uncommon for companies to offer servicing and repairs for premium machines and not actually know what they're doing or take any care in the quality of their work. Espresso Works is a welcome exception to this. Meaghan organised for Dom to both collect and return my machine; both times were prompt and on time. When it was returned, all surfaces had been wiped down and looked almost new again. All my valves, levers and taps are smoother and quieter than I'd have expected them to be on a several year old machine! They listened to what my concerns were about the machine before pickup and these were reflected in the service report on my invoice where each issue was looked into. In short, I highly recommend Espresso Works to anyone with a premium machine, especially those with ECM machines, as the work done on mine is fantastic and the experience interacting with their company was great.Posted on Google![]()

Top quality customer service. Great product range for high-end home coffee machines. I had small issues with my Torre Peppina. They sent a technician straight away to get it fixed and followed up to ensure the machine was working perfectly. I recommend buying with a local like Espresso Works Perth WA for the extra assistance post-sale.Posted on Google![]()
