Rocket Espresso · Flat burrRocket Spluga
A big, fast, on-demand flat-burr grinder Rocket built to sit next to its espresso machines on a cafe counter or a serious home setup. Large 65mm burrs and a touchscreen HMI give it commercial-grade throughput with prosumer-friendly dosing controls.
The short version
This is Rocket building a grinder to match the ambition of its espresso machines: big flat burrs, fast throughput, and a touchscreen that would not embarrass a cafe counter.
Accept that it wants counter real estate and volume use, it is not the grinder for a single dose ritualist with a small kitchen.
Why people buy it
- 65mm flat steel burrs and a strong motor mean fast, consistent grinding even back-to-back for guests
- Stepless Quick-Release Micrometric adjustment lets you make huge jumps or tiny tweaks without swapping mechanisms
Why they don’t
- Large footprint and weight (about 7.5kg) demand real counter space, this is not a compact home grinder
The full tally
- 65mm flat steel burrs and a strong motor mean fast, consistent grinding even back-to-back for guests
- Stepless Quick-Release Micrometric adjustment lets you make huge jumps or tiny tweaks without swapping mechanisms
- Touchscreen HMI with programmable doses, password lock, and usage counters feels genuinely commercial-grade
- Tool-free burr access keeps cleaning and maintenance quick
- Large footprint and weight (about 7.5kg) demand real counter space, this is not a compact home grinder
- Not a single-dose design, so bean-to-bean flavor switching means dealing with retained grounds in the chute
- No established aftermarket burr swap scene yet, so you are locked into Rocket's stock burr choice

Worth knowing before you buy — Most owners wish they'd paired it with a Rocket machine for visual/workflow cohesion; standalone appeal untested at home-barista scale.

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Home users who outgrow the entry Spluga for volume or thermal headroom step up to the Spluga Elite (600W motor, active cooling, up to 4g/s) or Rocket's larger commercial Stelvio line with bigger 68mm/83mm burrs.

- Grinder cleaning kit — Brushes and grinder tablets keep retention and stale grounds in check.
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. A balanced burr set: rotate origins freely — it will keep up.

Common questions

No. It is a hopper-fed, on-demand grinder designed for continuous use, not single-dose bean switching.
What is the difference between the Spluga and the Spluga Elite?
The Elite steps up to a 600W motor with up to 4g/s output and active 5-level fan cooling, versus the standard Spluga's 480W motor and 2.6-3.3g/s output.
