Overview
The Acaia Orbit is the first grinder from the company famous for its precision coffee scales. Featuring 64mm flat burrs and an integrated Acaia weighing system, the Orbit delivers precise grind-by-weight dosing with the accuracy Acaia scales are known for. The single-dose design achieves near-zero retention, and Bluetooth connectivity enables workflow tracking through the Acaia app. The Orbit represents a unique convergence of weighing precision and grinding quality, designed for the data-driven home barista who wants to know exactly what is going into every shot.
The Acaia Orbit features a 64mm flat burr set, crafted from steel. The burrs spin at 1200 RPM, offering fast grinding for high-volume use. Grind retention is approximately 0.2g — virtually zero retention, making it excellent for single dosing.
At $1,095, the Acaia Orbit is aimed at dedicated prosumers who demand top-tier grind consistency. Key workflow features include single-dose design (no hopper needed) and stepless grind adjustment for infinite precision. The flat burr design produces a more uniform particle distribution, prized for clarity and sweetness in the cup.
The Acaia Orbit is weighing 8.0 kg, manufactured in Taiwan, powered by a 250W motor. Its footprint measures 130 x 200 x 380 mm (W×D×H).

Our Verdict
The Acaia Orbit uses flat burrs, which are the preferred geometry for espresso among competition baristas and specialty coffee professionals. Flat burrs produce a more unimodal (uniform) particle distribution, which translates to cleaner, sweeter espresso with more clarity than conical alternatives. This is an end-game grinder for dedicated enthusiasts. The price is substantial but reflects the engineering required for top-tier particle uniformity. Pair it with a machine that does justice to the grind quality, and you'll taste the difference in every shot.
Frequently Asked Questions
Can the Acaia Orbit grind fine enough for espresso?
Yes, the Acaia Orbit is capable of grinding fine enough for espresso. Its stepless adjustment allows you to dial in precisely for any coffee.
Is the Acaia Orbit good for single dosing?
Yes, the Acaia Orbit is designed for single dosing. With only 0.2g of retention, virtually all the coffee you put in comes out ground. Weigh your beans before grinding for the most consistent results.
Why choose flat burrs in the Acaia Orbit?
Flat burrs produce a more uniform (unimodal) particle distribution compared to conical burrs. This translates to cleaner, more transparent espresso flavors with pronounced sweetness and clarity. Many competition baristas and specialty roasters prefer flat burr grinders for this reason.
How do I maintain the Acaia Orbit?
Clean out retained grounds after each use with a brush or bellows. Deep clean the burrs every 2-4 weeks by removing them and brushing away oil buildup. For the motor, occasional use of grinder cleaning tablets (like Grindz) helps remove coffee oil buildup. Never wash burrs with water.
Is the Acaia Orbit worth $1,095?
The grinder is the most important variable in espresso quality — more important than the machine. Investing in a quality grinder like the Acaia Orbit will have a bigger impact on your espresso than upgrading any other piece of equipment. If you're serious about espresso, this level of grinder investment is justified.
