Weber Workshops Coffee Grinders: Models & Alternatives
Weber Workshops currently lists four coffee grinders: the electric EG-1 Mk.3 and Key Mk.2, plus the hand-powered HG-2 Mk.2 and SG-1. The BIRD sometimes appears beside them in site navigation, but it is a brewer—not a grinder.

Brand and generation history
The HG-1 established the company’s reputation for mechanically elaborate manual grinders. The EG-1 followed as its flagship electric flat-burr design, while Key applied a large conical burr set to a very narrow electric body. Current generation labels matter: EG-1 is Mk.3, while Key and HG-2 are Mk.2. Older EG-1, Key Mk.1 and HG-1 units differ in features and should be evaluated by generation rather than name alone.
EG-1 Mk.3
The EG-1 uses 80 mm blind-mounted flat burrs and variable speed. Weber currently offers CORE burrs for espresso and filter and SSP-made ULTRA burrs for filter-focused use; Weber specifically says ULTRA is not suitable for traditional espresso. Adjustment moves in five-micron steps.
Verified dimensions are 235 mm deep, 245 mm wide and 456 mm high, with a weight of 13.5 kg. It accepts 90–240 V at 50/60 Hz through a C13 power cord. Mk.3 adds a purge button that can reverse briefly from a stop and then run at maximum speed. The magnetically closed grind chamber opens without changing the grind setting, making burr access one of the platform’s distinguishing features.
Key Mk.2
Key uses 83 mm Mazzer conical burrs that Weber partially seasons and coats with TiN. Speed is adjustable, the grind setting moves in five-micron steps, and the loading chamber holds about 40 grams. Mk.2 adds 50% more torque than Mk.1, an integrated bean feeder and an updated Magic Tumbler.
Key measures 248 × 109.2 × 349.6 mm and weighs 9 kg. Its electrical range is 90–240 V, with 350 W maximum power. It ships with the 58 mm Magic Tumbler; the standard 49/58 mm tumbler and funnel are separate.
HG-2 Mk.2 and SG-1
HG-2 is the manual counterpart to Key’s burr concept. It uses the same 83 mm-class Mazzer conical burrs, a two-speed transmission, five-micron stepped adjustment and a folding crank. Weber lists the Mk.2 as current and in stock by finish at the time of this review.
SG-1 remains on Weber’s official grinder collection but is marked sold out. Because its product page is not currently accessible, this guide does not repeat secondary-market dimensions or burr claims as if they were current manufacturer specifications.
Comparable Espresso Outlet grinders
The Turin DF83V is the closest stocked alternative to the EG-1 in overall concept: large flat burrs, single dosing and variable speed at a much lower price. The DF64V is more compact. For a commercial conical comparison to Key, the Mazzer Kony SG uses a very different hopper-fed, grind-by-weight workflow.
Weber Workshops FAQ
Which Weber grinder works for both espresso and filter?
EG-1 with CORE burrs is explicitly sold for both. Key can also cover a broad range. EG-1 ULTRA burrs are filter-specific according to Weber.
Are Key and HG-2 the same grinder?
No. They share an 83 mm Mazzer conical-burr concept, but Key is electric and variable speed; HG-2 is manual with a two-speed gearbox.
Is the BIRD a grinder?
No. BIRD is Weber’s piston-driven, non-bypass brewer.
