In brief
The Faustino is Rocket Espresso's small home espresso grinder. Retailers list the current model as the Faustino 3.1.
Rocket specifies 50 mm flat burrs, stepless adjustment and three programmable doses. It is styled to sit beside Rocket's machines.
Whole Latte Love calls it one of the smallest grinders it has handled, and Rocket lists it at 162 mm wide. It is a compact grinder for a crowded counter.
The trade-off is burr size and evidence. Its closest rival, the Eureka Mignon Specialità, has larger burrs and far more published reviews behind it.
What it does well
- Small footprint: Rocket lists it at 162 mm wide
- Stepless adjustment on the bottom burr, so cleaning does not lose your setting (Whole Latte Love)
- Three timed doses set to a tenth of a second, plus a continuous button
- A Home-Barista owner reports four to five years of daily use and still loves it
Where it falls short
- That owner says some roasts need a finer grind than it reaches before the burrs touch
- 50 mm burrs, smaller than the 55 mm in the Eureka Mignon Specialità
- Timed dosing from a hopper; no grind-by-weight

What it does well
Adjustment is stepless. Whole Latte Love says the knob moves only the bottom burr. That means you can lift the top burr out for cleaning without losing your setting, and it takes three screws to do it.
Dosing is simple. Rocket lists three programmable doses and a continuous mode. Whole Latte Love says each dose adjusts to a tenth of a second, and a pin holds the portafilter for hands-free grinding.
It is small and tidy. Rocket gives 162 × 246 × 388 mm and 6.9 kg. Whole Latte Love credits anti-vibration design for quiet grinding and says the hopper holds up to 1.5 pounds.
On Home-Barista, one owner reports four to five years of daily use with a Lelit Elizabeth and says "I do love it." That is one owner, but it is real long-term use.
Where it falls short
The fine end can run out. That same owner says that for about one roast in ten, the Faustino will not go fine enough before the burrs start to "chirp." Rocket told the owner the chirp marks the grinder's zero point, and not to go finer.
Home-Barista replies suggested checking burr alignment with a marker test before blaming the grinder. Misaligned burrs can make shots run fast. Shimming was suggested as another fix.
The burrs are 50 mm. The Specialità uses 55 mm. One Home-Barista reply doubted the fines would differ much between the two.
Dosing is timed, from a hopper. There is no grind-by-weight. If you change beans every day, a single-dose grinder fits better.
Reviews are thin. Published coverage is mostly retailer copy and owner threads, with no measured retention or noise figures for the 3.1.
Who should buy it, and who shouldn't
Buy it if you make espresso, want a small stepless grinder, and like a matched set with a Rocket machine. It suits one house coffee kept in the hopper.
Skip it if you brew filter, if you chase very fine, light-roast espresso, or want the largest burrs at this size.
How it compares
The Eureka Mignon Specialità is the closest rival. It is also stepless and timed, with 55 mm burrs. The Home-Barista thread above weighs the two directly.
The DF64 Gen 2 is a single-dose grinder with 64 mm burrs. See DF64 Gen 2 vs Rocket Faustino for how the dials line up.
The Eureka Mignon Silenzio costs less and is also stepless and timed, with 55 mm burrs per Eureka. If you own an older Rancilio Rocky, Rancilio Rocky vs Rocket Faustino shows how the dials line up.
Owning it
Cleaning is straightforward. Whole Latte Love says three screws release the top burr, and the bottom-burr adjustment keeps your setting. Our guide to cleaning a burr grinder covers the routine.
Rocket sells through dealers, so ask yours about parts before you buy. One Home-Barista reply suggests burrs may need changing after about five years of use. When they do, see how to replace grinder burrs.
Pro Coffee Gear lists a 12-month parts warranty. Find the chirp point when the grinder is clean, then use the settings chart on this page as a starting point. Dialing in a new grinder covers the rest.
