ACAIA
A hopper built for single-dose and batch
The Multi-Purpose Hopper doubles as a single-dose funnel and an adapter for Acaia's larger batch dosing hoppers, up to 2kg capacity — one grinder that scales from a single shot to a full day's prep.
ACAIA
Stepless adjustment dial
A streamlined dial gives precise, effortless grind control from espresso to filter in one continuous sweep. Space Grey adds a detent ring to mark grind positions; Black and Beige White use a wide, plain dial.
ACAIA
Grind-by-weight with Lunar
Paired with an Acaia Lunar scale over Bluetooth, the Orbit grinds to an exact dose automatically in single or batch mode — no pre-weighing beans, just a consistent output every time.
ACAIA
Mazzer 33M — classic espresso body
Designed for classic espresso styles, the Mazzer 33M burr set also handles modern lighter roasts well, and leans towards balanced flavour and higher texture when brewing filter.
ACAIA
SSP Multi-Purpose — high-clarity brews
Built for high-clarity brewing, the SSP Multi-Purpose burr set excels at modern espresso styles and light filter coffee, with excellent consistency shot to shot.
ACAIA
SSP Lab Sweet V3 — sweetness across both
Building on the popularity of Lab Sweet V1/V2 for filter, the Lab Sweet V3 now works for espresso too — crafted for superior balance and a sweeter cup across brew styles.
ACAIA
RPM Stability Control Technology
Acaia's proprietary RPM Stability Control Technology holds motor speed steady as the hopper empties, where conventional grinders speed up — reducing noise and heat while keeping particle size consistent shot to shot.
ACAIA
Built to minimise retention
A knocking chute and automatic purge clear grounds after every dose, so single-dosing stays quick and mess-free. Independent measurements have found retention as low as 0.1–0.4g, well suited to switching beans often.

Frequently asked questions
Which burr set should I choose — Mazzer 33M, SSP Multi-Purpose or SSP Lab Sweet V3?
Mazzer 33M suits classic, high-body espresso and works well with lighter roasts too. SSP Multi-Purpose favours high-clarity, modern espresso and light filter. SSP Lab Sweet V3 is built for balance across both, for a sweeter cup. All three are 64mm and swap without tools.
Can the Acaia Orbit grind for both espresso and filter coffee?
Yes. The stepless dial covers the full range in one sweep — roughly +2 to +3 on the dial for espresso and +6 to +12 for batch filter — so you don't need a separate grinder for each.
Do I need an Acaia Lunar scale to use grind-by-weight?
The Orbit grinds on its own via time or the companion app, but grind-by-weight and grind-by-time automation only unlock once it's paired over Bluetooth with an Acaia Lunar scale.
How do I clean and maintain the Acaia Orbit?
Wipe the hopper, chute and burr chamber with a soft, dry cloth. Never immerse the grinder or any part in water, and avoid detergents or chemical cleaners, which can damage the finish. It carries a 2-year manufacturer warranty.
