Know before you buy
These large burrs are TiN-coated and come with proprietary seasoning, which helps produce a highly consistent grind profile specifically optimized for espresso. The size and geometry allow for exceptional clarity and texture in the cup compared to smaller burr sets.
Adjusting the RPM between 50 and 300 allows you to control the speed at which beans are fed through the burrs. Lower speeds can reduce heat and fines, giving you more control over the flavor profile and extraction characteristics of your specific coffee beans.
While the KEY is engineered specifically for espresso, its precision adjustment system allows for a range of grind sizes. However, it is optimized for high-end espresso workflows and may not be the most efficient choice if you primarily brew filter or pour-over coffee.
The Magic Tumbler is designed to catch grounds directly from the chute, minimizing mess and static. It integrates seamlessly into your workflow, allowing you to transfer grounds directly into your portafilter without the need for additional dosing tools.
The KEY is designed for easy access, making routine cleaning straightforward. While the parts are not dishwasher safe, the simple construction allows you to clean the burr chamber and Magic Tumbler quickly to ensure consistent performance and flavor.
Yes, the grinder features an ultra-thin 80mm body width, making it one of the most space-efficient high-end grinders available. Its compact footprint is ideal for kitchens where counter space is at a premium.
