Rancilio Rocky vs Wilfa Uniform
Two grinders cross-shopped at the same money. The Uniform is numbered 1–41; the Rocky is numbered 0–55.
Which to buy

Rocky if you…
- are buying used — Rancilio no longer lists the Rocky
- grind from a 300 g hopper
- want a doser version with a manual dosing lever
Choose the
Uniform if you…
- want to buy new — Wilfa gives a five-year warranty
- want a 75 g hopper that stops when the beans run out
- brew espresso to press pot — Wilfa says its 41 settings run from coarse to real espresso

Rancilio no longer lists the Rocky (its page now returns 404) and sells the Stile as its home grinder, so you'd be buying the Rocky used.

The same number means different things
Both grinders use a numbered dial, which makes it tempting to copy a number straight across. Setting 21 sits at grind index 31.7 on the Rocky but 31.7 on the Uniform — close, but worth checking.
Converting a setting
If a recipe quotes a setting for one of these grinders, read across for the equivalent on the other. Rows are spaced evenly by grind size, not by dial number — on a conical burr those are not the same thing.

The shape of each dial
Where the connectors bunch, that grinder’s dial is compressed and single steps count for more. Comparing the two shapes tells you which gives finer control, and where.

Dialing in the Rocky
A stepped espresso grinder that has been the budget recommendation for a very long time. The 55 steps across 50mm flat burrs are its limitation — for espresso you will sometimes want a setting between two of them and there is not one, and a single step can move a shot by seconds. Twenty of those steps cover espresso through filter, which is more resolution than the fine end usually gets at this price. Two things make it an espresso grinder in practice rather than a general one: changing setting means holding the locking lever while twisting the hopper, and it keeps a couple of grams in the chute, so every switch between espresso and pour over costs you both fiddling and coffee. Most owners pick one end and stay there.
Dialing in the Uniform
Designed with Tim Wendelboe for filter coffee, and honest about it. Forty-one settings across a wide range, flat burrs, and a grind that is genuinely clean in the brew band it was built for. It does reach espresso fineness — but the step size is the problem rather than the range: reviewers report landing between settings, where one step chokes the basket and the next runs fast, with only a narrow window in between. Treat occasional espresso as possible with technique rather than as something the grinder is for. For pour over, which is the job, it is one of the better flat-burr options at the price.
