weber key mk2 1

In October of 2023, Weber Workshops is releasing its next generation of the epoch-making KEY Coffee Grinder. In June of 2021 the KEY marked a new era of home user expansion for Weber by taking the biggest commercially- available coffee burrs to an impossibly compact grinder. The second version of the KEY, the Mk ii, was created to further improve the product usability and workflow with several improvements.

First is an improved bean loading and anti-popcorning lid. Two sides of a magnetic circular lid lift either directly apart, or straight up and suspended with magnets while the beans are loaded into the burr chamber. Once loaded, the cover easily drops right back down into place preventing any fragments from bouncing out. The new loading chamber is also around 30% bigger, allowing for the larger dose size of many pour-over coffee methods up to ~40g at a time.

The Mk ii also boasts a massive 50% increase in torque from its predecessor. This was achieved through a combination of a new gearing system and higher current power supply. The Mk ii can effortlessly grind through extremely light roasts down to green coffee, even at fine settings at the lowest RPM (30 RPM) setting. Utilizing the same 83mm Mazzer burr set as its predecessor, it remains the largest commercially available conical burr set on the market, with a slimmer footprint than many grinders with burrs a fraction of its size.

Another new feature is the removable and customizable wooden platen and brush handles. This makes it easier for the user to match the wood accents of their KEY to their kitchen or coffee bar. WW plans to release these in Oak, Walnut, and Teak.

The KEY Mk ii will also be shipping with an updated version of Weber Workshops’ industry-first Bean Feeder mechanism, a device made specifically for single-dosing coffee into the grinder. The feeder was based on observing user patterns where they would “babysit” the shot grinding and feed in the beans slowly so as to avoid saturating the burrs at any given point during the grinding. This ensures that the grind profile is identical at the beginning of a shot as at the end.

The KEY Mk ii will also ship with an updated version of its patented Magic Tumbler, a grounds control dosing funnel with integrated WDT tool (a stainless wire that mixes up the freshly ground coffee to homogenize the grounds, a proven method in improving espresso extractions). The new version takes a cue from the company’s flagship grinder, the EG-1, and incorporates a replaceable paper wiper that makes physical contact with the exit point of the grounds, ensuring minimal grind retention well beneath 1/10g, below what most coffee scales are capable of measuring.

Douglas Weber, the Founder and CEO of Weber Workshops, says, “The launch of the KEY on Indiegogo in the summer of 2021 exceeded our wildest expectations. We listened to our customers’ feedback to create what we think is a great improvement to an already stellar platform.”
