Overview

Now Mk2 Edition

For an extended period, the HG-1 reigned supreme as the definitive standard in manual coffee grinders. However, after meticulous refinement and enhancements over the course of a decade, it has been reborn in the form of the HG-2.

Now available in the latest Mk.2 iteration, the HG series proudly showcases all the cutting-edge innovations pioneered in the KEY Mk.2 edition: an Integrated Bean Feeder housing a new bottom bearing, a 30% increase in loading capacity, and an improved Magic Tumbler to eliminate the need for RDT.

For those who grind by hand, this represents the pinnacle of what is achievable.

Maintenance and Cleaning

The HG-2 has been designed from the start to be both simple and easy to clean. No tools, and a full clean in seconds, not hours.

The dust lid can be removed or suspended above with magnets to reveal the bean feeder aperture at the top of the burrs. A few brush strokes and blasts of air on top can dislodge any powder above the burrs. The lower funnel is held in place by 12 strong rare earth magnets and can be removed with a simple twist of the wrist. Once exposed, the lower burrs can be brushed clean in seconds.

We believe that a good product is a clean product, and designing them to be easy to clean is fundamental to improving the quality of your coffee and the hygiene of your countertop.

Burr Alignment

The HG-2 comes factory pre-aligned, and cleaning or normal use will not disrupt this. You should never need to touch this. At the factory, we make sure that each axis is aligned and centered to the best capability of the set of burrs being used. We then tighten it all down, grind an espresso shot for verification, and clean the burrs before boxing it up. This means you may see a tiny amount of coffee dust in the product, but it is not "used."

Burr Replacement

The HG-2’s pre-seasoned 83mm Mazzer Conical Burrs are rated for over 5,000Kg of coffee, theoretically they should last you several lifetimes. Small pebbles in your bag can throw a wrench in their longevity, however.

If you do need to replace them, we stock our burrs that come with our proprietary partial pre-seasoning and life-prolonging food safe TiN coating. Find them here.
