Mazzer Kold S Commercial Espresso Grinder

The Coolest Operator in the Room. Speed, Consistency, and Science combined.

For the high-volume café where the line never ends and equipment performance is non-negotiable, the Mazzer Kold S is the definitive solution. As its name suggests, this machine is engineered to conquer the number one enemy of espresso consistency: Heat.

In standard grinders, hours of continuous operation transfer motor heat directly to the beans, altering the extraction time and flavor profile. The Kold S solves this with a revolutionary belt-driven architecture and a low-RPM motor. It protects your coffee’s delicate aromatics, ensuring that the shot pulled at 5:00 PM tastes exactly like the one pulled at 7:00 AM.

Why the Mazzer Kold S is the Ultimate High-Volume Workhorse

1. The "Kold" Architecture (Belt-Driven Cooling)

The Kold S is designed from the ground up to thermally isolate the coffee.

• Belt-Driven Transmission: By physically separating the motor from the grinding chamber via a belt drive, Mazzer ensures that motor heat never migrates to the burrs.
• Low RPM / High Torque: The motor spins at a gentle 420 - 500 RPM. This low speed drastically reduces friction heat while maintaining massive torque.
• Active Cooling: A powerful Double Fan System pulls cool air through the chassis to dissipate any residual ambient heat.

2. 71mm Conical Burrs (The Speed Demon)

Don't let the low RPM fool you; the Kold S is a beast.

• Massive Output: It delivers an average grinding speed of 6 grams per second, making it one of the fastest grinders Mazzer has ever built.
• Conical Profile: The 71mm Conical Burrs (100% made in Italy) are legendary for producing a grind with excellent particle distribution, enhancing the body and texture of the espresso.

3. Grind Flow Control (GFC)

Static and clumping are things of the past. The Kold S features Mazzer's innovative GFC System.

• The Damper: A removable aluminum outlet insert utilizes a wire damper to neutralize static, ensuring the grounds fall fluffy, centered, and clump-free into the portafilter.
• Customizable: The machine includes three interchangeable dampers (Hybrid, Anti-Clumping, and Anti-Dust), allowing you to customize the flow based on your specific roast level and humidity environment.

4. Precision & IoT Connectivity

• Micrometric Adjustment: The adjustment knob features a Lap Counter, allowing baristas to make tiny, repeatable changes to the grind size with absolute visual precision.
• Easy Clean: The grinding chamber can be accessed for cleaning without losing your grind setting—a massive time-saver for closing shifts.
• IoT Ready: Equipped with modern connectivity, the Kold S allows operators to track usage statistics and maintenance intervals remotely.

Technical Specifications

Ideal Applications

The Mazzer Kold S is specifically designed for:

• High-Volume Chains: Where speed (6g/s) is critical to keeping the line moving.
• Specialty Cafés: Where thermal stability is required to protect the flavor of expensive single-origin beans.
• Busy Espresso Bars: The low RPM and belt drive make it quieter and cooler than almost any competitor in its class.

Maintenance & Care

• GFC Cleaning: The aluminum GFC insert is removable. We recommend checking the wire damper weekly to ensure no coffee oils are building up, which could restrict flow.
• Chamber Access: The Kold S allows for "zero-loss" cleaning. You can open the chamber to vacuum out the burrs without losing your dial-in setting.
• Burr Life: Conical burrs are extremely durable. However, given the high volume this machine is built for, inspect burrs annually for sharpness.
