Rocket Espresso · Flat burrRocket Stelvio
Rocket's tallest, most powerful grinder to date, a commercial-grade flat-burr unit co-engineered with Macap and aimed at busy cafe bars rather than home counters.
The short version
This is Rocket borrowing Macap's Supra 68 guts and dressing them in Rocket sheet metal and a touchscreen, built for volume service rather than single-dose home tinkering.
Buy it for café-grade throughput and Rocket's fit and finish, not because it is some breakthrough in grind technology.
Why people buy it
- 68mm flat burrs and a 550W motor push 3.8-4.5 g/s, fast enough to keep a busy bar moving during rushes
- Quick-release micrometric adjustment lets baristas jump between micro and macro settings without fumbling
Why they don’t
- Brand new as of late 2025 with no independent long-term reliability data yet
The full tally
- 68mm flat burrs and a 550W motor push 3.8-4.5 g/s, fast enough to keep a busy bar moving during rushes
- Quick-release micrometric adjustment lets baristas jump between micro and macro settings without fumbling
- 1.5kg hopper and 3.5-inch touchscreen HMI suit high-volume commercial dosing workflows
- Shares proven Macap Supra 68/83 grinding mechanics with Rocket's own design and finish
- Brand new as of late 2025 with no independent long-term reliability data yet
- At 638mm tall it needs serious counter clearance, a poor fit for home kitchens
- Priced and sized for commercial deployment, overkill and awkward for single-dose home use
What the community knows
Years of owner threads, distilled.
Premium flat-burr engineering hobbled by near-zero community footprint, absent owner long-term data, and a $2000 CAD ask that sits orphaned between established prosumer defaults and modular platforms where the community lives and troubleshoots.

Worth knowing before you buy — Most buyers of premium grinders at this price ask why they aren't buying a Niche, Fellow, or Fellow Ode—machines with thriving communities and documented mod culture.

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Sits below the Stelvio Élite (83mm burrs, 750W, 6g/s) for shops needing even higher throughput; home users chasing this tier would more typically land on Rocket's Spluga or a single-dose premium grinder instead.

Feed it right
Week one is dial-in — and stale beans will lose it.
Coffee more than a few weeks past roast won’t extract predictably, and a new grinder gets blamed for it. These burrs lean bright — washed single-origins with real acidity are where they earn their price.
