High-Performance Grinding, Made Affordable
The core idea behind the E37Z-Naked is simple, keep retention as close to zero as possible. The body is tilted at 45 degrees, using both gravity and geometry to help grounds clear the path quickly and cleanly.
The burrs and grinding chamber also feature a diamond-like carbon (DLC) coating, which greatly reduces surface friction and helps prevent grounds from clinging to the metal.
In addition, the included bellows and spring-loaded outlet chute help purge any fines that might remain in the chamber. The result is near-zero retention from shot to shot, minimizing flavor carryover and making the E37Z-Naked ideal for single dosing.
Even if you switch origins or roast profiles every shot, you can keep tastings clean and consistent without wasting beans or time.
60+ Years of Expertise at the Core
The heart of the grinder is a 3.3 inch flat burr set that draws on more than 60 years of expertise from the manufacturer, Ceado.
These burrs also feature a diamond-like carbon (DLC) coating, and they are designed specifically for the E37Z with no screw holes or other features that can trap grounds.
The upper and lower burrs are designed with different geometries, aiming for a stable, consistent particle distribution built around single dosing.
The supported range includes:
- Ultra fine grinding for Turkish style coffee
- Espresso
- Drip and pour over
- French press
- Coarse grinding for cold brew
This is not a grinder only for espressos.
It is designed to be a true first choice grinder that can support an entire café coffee program.
Ultra precise, fast grind adjustment
For grind adjustment, a worm gear system with a large knob finished with wooden trim is used. The worm gear’s high reduction ratio lets you make very fine adjustments by feel, the kind of tiny changes espresso requires.
This offers two key benefits:
- The setting stays stable, no lock needed
- Quick release by turning and pressing the nut
This is what makes the E37Z Naked stand out. You can move quickly across a wide range, from ultra fine espresso to coarse filter grinds, without wasting beans.
High build quality and easy maintenance
The E37Z Naked is built from robust, precision machined components. It also features a protected design that helps keep coffee oils and fine dust from building up on the adjustment threads, a level of attention to detail typical of Ceado’s higher end models.
Maintenance is built in as well. You can access the grinding chamber by removing just three bolts, and even after disassembly and cleaning, the grind zero point stays aligned when you reassemble it. For high-end commercial grinders, having the flavor shift every time you clean is a serious problem, and the E37Z Naked is engineered to avoid that risk by design.
One more standout feature is that each unit comes with its own particle size distribution test sheet, measured using the Malvern Mastersizer 3000, a top-tier particle analysis system used worldwide. You can think of it as a manufacturer-issued certificate that this specific grinder meets a defined standard for particle distribution performance.
4 Reasons Professionals Choose It
Designed for true zero retention
With a layered approach that combines DLC coating, a 45 degree body design, bellows, and a spring loaded chute, it minimizes flavor carryover from the previous dose, making it ideal for single dosing.
All brew methods, one grinder
Because it works across the full range, from Turkish to espresso to filter to cold brew, you’ll never have to lock it into a single, brew-specific role.
Precise dialing and quick switching
Easy micro and macro adjustment makes it highly practical for cafés that change recipes frequently throughout service.
Transparent quality assurance
A particle distribution test sheet is included for each unit, giving professionals peace of mind, especially if they want consistency they can verify in numbers.
3 Key Benefits
- With true zero retention, switching coffees takes little to no purging, which reduces waste and keeps workflow efficient.
- It pairs exceptionally well with cafés that rotate single origins shot by shot, or serve both espresso and filter coffee.
- Because you do not need to re-find the grind zero point after every cleaning, it helps keep flavor consistent while reducing staff workload.
E37Z-Naked――
A commercial grinder built for modern coffee service, where you can switch beans from shot to shot without compromise. Together with your espresso machine, it is a strong first option to consider when you want to take the foundation of your café’s flavor to the next level.
