Mazzer Kold S

Low-RPM, cool-running grinding for busy espresso bars.

The Mazzer Kold S is a high-performance commercial espresso grinder designed for busy coffee bars where speed and temperature management are critical. Its 71 mm conical burrs, low-RPM operation, belt-driven transmission and double cooling system help protect coffee from excess heat during extended grinding, while electronic on-demand dosing supports a fast professional workflow. For high-volume cafés looking for powerful grinding with strong thermal management, the Kold S is built for sustained commercial use. Modern Standard Service is an approved Mazzer reseller. We supply, install and service Mazzer grinders, including burr replacement and calibration — see our Mazzer sales, installation and service page.

This isn't part of our standard installed range, so we quote it for your site and how you'll use it. If something in our core range would suit you better, we'll tell you.

What we'd usually recommend

For most espresso bars we recommend a grinder from our core range. These are the grinders we price up front, install alongside our espresso machines and support day to day.
