Overview
The Weber Workshops KEY represents a radical rethinking of conical burr grinding. Featuring massive 83mm conical burrs spinning at a remarkably slow 400 RPM, the KEY prioritizes flavor clarity above all else. The innovative magic tumbler catch cup uses static-eliminating technology to deliver fluffy, clump-free grounds with near-zero retention. The minimalist design eliminates a traditional hopper in favor of a single-dose loading tube. Every aspect of the KEY has been engineered to maximize cup quality: the slow speed preserves volatile aromatics, the large burrs create exceptional uniformity, and the low-retention path ensures every gram of coffee you grind ends up in your portafilter. A grinder for those who believe the journey to perfect espresso starts with perfect grinding.
The Weber Workshops KEY features a 83mm conical burr set, crafted from steel. The burrs spin at 400 RPM, a deliberately slow speed that minimizes heat buildup and preserves coffee aromatics. Grind retention is approximately 0.1g — virtually zero retention, making it excellent for single dosing.
At $3,295, the Weber Workshops KEY is aimed at uncompromising enthusiasts and professionals who want the absolute best. Key workflow features include single-dose design (no hopper needed) and stepless grind adjustment for infinite precision. The conical burr design is known for producing a slightly bimodal grind distribution, which many enjoy for its body and complexity in espresso.
The Weber Workshops KEY is weighing 9.5 kg, manufactured in Taiwan, powered by a 200W motor. Its footprint measures 110 x 150 x 350 mm (W×D×H).

Our Verdict
The Weber Workshops KEY from Weber Workshops is a solid option in the premium grinder segment.
