A Finish Choice, Not a Performance One

The axis here isn't technical — this grinder performs identically to the standard-finish REV Zero WAM, right down to the roughly 2g SweepOut retention figure and the 4-ton-rated Red Speed burrs. The axis is aesthetic: a bar that already wants the REV Zero's single-dose, low-retention positioning and is willing to pay for a finish that visibly sets its counter apart from every other REV Zero in the room.

That's a fit for a flagship café location, a roastery tasting bar, or any operator treating equipment choice as part of the room's design language — somewhere the grinder itself is part of what a customer notices while waiting on a shot. It's a weaker fit for a multi-location group standardizing on one spec sheet across several bars, where matching finishes across locations usually matters more than a standout unit at any single one of them.

Buyers who want the identical performance without paying for the limited finish should look at the Ceado REV Zero WAM in Ceado's standard colorway — same burrs, same SweepOut cycle, same WAM dosing.

Did You Know

• SweepOut Dual Spin is a patented reverse-grinding cycle: after each dose, the burrs briefly spin backward to clear the grinding chamber before the next shot is ground. It's this reversal, not just a wider chute, that gets retention down to roughly 2 grams and pushes about 99% of ground coffee into the portafilter.

• Limited-run finishes like ONYX are a common move for flagship equipment models — a way to give a top-tier machine a visual signature without engineering a new internal platform. The internals underneath stay identical to the standard-finish grinder; only the exterior treatment is exclusive to the edition.

• Every REV grinder — Steel, Titan, or Zero — shares the same roughly 1,600g hopper capacity, regardless of burr coating or tier. Ceado standardized hopper size across the whole REV platform, which keeps hopper lids and stands interchangeable across the range.

What's different between the ONYX Edition and the standard Ceado REV Zero WAM?

Nothing technical — this grinder uses the identical 83mm Red Speed burrs, SweepOut Dual Spin cycle, and WAM dosing module as the standard-finish grinder. The only difference is the ONYX exterior finish.

Is the ONYX Edition more expensive than the standard REV Zero WAM?

Pricing reflects the limited-run finish rather than any technical upgrade — the grinder underneath, from the Red Speed burrs to the WAM dosing module, is unchanged from the standard REV Zero WAM.

Is the REV Zero ONYX Edition also used in World Barista Championship competition?

Ceado's World Barista Championship sponsorship covers the REV Zero platform generally; the ONYX finish is a cosmetic option on that same platform rather than a separate competition designation.

What burr coating does the Ceado REV Zero ONYX Edition use?

Red Speed — a titanium-and-aluminum coating on 83mm flat burrs, rated for roughly 4 tons of throughput, identical to the standard-finish REV Zero WAM.

Does the ONYX Edition include WAM as standard?

Yes — every REV Zero ONYX Edition unit ships with WAM fitted, dispensing to 0.1g across three programmable doses plus a manual setting.

How does SweepOut Dual Spin work on this grinder?

After each dose, the burrs briefly reverse direction to sweep the grinding chamber clear before the next shot — the mechanism behind this grinder's roughly 2-gram retention figure.
