Mazzer Mini G vs Weber Workshops Key Mk.2
Two answers to the same question — the split below is the whole argument.
Mazzer
Strong consensusCA$2,200–2,500 · US$1,795–1,995
This is the old bulletproof Mazzer Mini shape with a scale grafted in, and it does exactly what it promises: same dose in, same dose out, shift after shift. Accept the roughly 8-gram hopper…

The Key Mk.2 leans clarity and sparkle; the Mini G leans syrup and body. Pick the cup, not the machine.
The counter’s vote
Looks barely figure in either machine’s record — the counter can sit this one out.
Mini G: Utilitarian, industrial aesthetic — no kitchen-approval polarization; looks are intentionally transparent, not a purchase driver or detractor.
Key Mk.2: Award-cited design (Weber founder background, iPod-era aesthetics) drives purchases; customizable wood accents and compact form make it a kitchen statement, though some find the utilitarian…
Only the Key Mk.2: a single-dose workflow.
Where they tie: espresso duty · built to last · quiet operation — don’t let a spec sheet invent a difference.
So — which one?
Take the Mini G if —
- Syrupy, traditional cups are the goal
- It has to just work, every day
- Every dollar has to earn its place
Take the Key Mk.2 if —
- Bright, separated cups are the goal
- You rotate beans and hate purging
- You brew more ways than one
- You weigh every dose anyway
Both columns reading true? Take the one your gut already picked — then stop reading reviews. Fresh beans will move the cup more than this choice will.
Known weak points
Mini G
Brush wear on older models (documented in Home-Barista threads); motor longevity documented as excellent with proper maintenance; no widespread catastrophic failure pattern reported.
Key Mk.2
Motor stall on Mk.1 (fixed in Mk.2 via 50% torque increase); shaft alignment drift (Mk.1 issue, mitigated in Mk.2 with integrated bottom bearing); anti-static plate degradation under grinding stress; bean feeder reliability concerns early in production.
