The Key Mk.2 from Weber Workshops redefines what a compact, high-performance grinder can be.
Building on the legacy of the original Key, the Mk.2 maintains the same ultra-efficient footprint while introducing major improvements in workflow, usability, and precision.
At the heart of The Key is a massive 83mm conical burr set, originally manufactured by Mazzer and then enhanced by Weber’s unique treatment process, including pre-seasoning and a food-safe TiN coating.
This ensures optimal performance right out of the box, delivering outstanding grind consistency and flavor clarity across espresso and filter brews.
Despite housing such large burrs, The Key’s design remains impressively space-saving.
Designed by the team behind the iPod Nano, every detail is engineered for performance and elegance.
New in the Mk.2 is an integrated cleaning brush with a solid oak handle, brass ferrule, and replaceable bristle head, neatly stored via a hidden magnet. Also added is an intuitive RPM adjustment knob, allowing users to fine-tune motor speed for different brew styles.
The Key Mk.2 features a 50% increase in torque compared to the original model, thanks to a new gearing system and upgraded power supply—allowing it to grind even the lightest roasts with ease.
A redesigned magnetic dust cover now sits atop a 30% larger loading chamber with approximately 40g capacity, making dosing cleaner and more efficient while preventing coffee fragments from escaping.
Grind adjustment is simple and precise, thanks to 5-micron stepped settings, allowing you to move seamlessly from Turkish-fine to pour-over ready.
