Acaia Orion Bean Doser – Automatic Dosing by Weight
It's rush hour. You place a cup on the platform, and before you even grab the next one, the Orion has weighed the dose, given a short beep, and is already waiting for the one after that. No counting, no second scale, no pausing – just a steady stream of beans, cup after cup, precisely by weight.
It's the invisible rhythm behind a calm bar: When dosing runs by itself, your mind is free for the coffee.
What makes the Acaia Orion Bean Doser special
The Orion doses whole beans by weight before they go into the grinder – and it does so quickly: 225 grams in twelve seconds, 20 grams in three, with a margin of error of just two to three beans. A patented auger moves the beans gently, without damaging them. In fully automatic mode, dosing starts as soon as a container is on the platform and stops with a beep at the target weight. That way you fill a row of cups without pressing a single button.
With the rotary wheel you save three target weights and choose between three modes: Precise for small doses, Fast for large quantities from around 100 grams and Green for green coffee – for example for sample roasting or packing at the roastery. The intelligent system compares target and actual weight and fine-tunes itself over time. And if one or two beans are missing at the end, you add them by hand until the weight is exactly right.
For us, this ties in with a simple conviction: good coffee starts with the ratio, and an espresso at around 1:2 depends on the input dose being right. No shot is like yesterday's, because the bean, the humidity and people change every day – a constant dose at least takes one variable out of the game. The Orion delivers this consistency without anyone at the counter having to keep an eye on the scale all the time.
Do you need a device like this? Honestly: no. A scale and a little routine will do too. The Orion is for everyone who cares about flow – the even dosing, the rhythm gained, the time that flows back into the actual craft. You either want it or you don't. Both are perfectly fine, and that's just our view, one of many.

Who the Orion is made for
The Orion is for settings where a lot is dosed, and consistently – the coffee bar at rush hour, the roastery when packing or sample roasting, the cupping table. In scale mode, it also works as a countertop scale with a capacity of 3000 grams. If you prefer to weigh single doses very compactly, you'll find its smaller siblings in the Orion Nano or Orion Mini; our Acaia Collection shows all three. Every setup is welcome with us, from a single counter to an entire roastery.
Pairs well with
Right after the dose comes the grinding – in our coffee grinders you'll find models for every throughput. The whole Orion universe, scales and other precision tools are in our Acaia Collection.
When weighing in the cup: if you want something compact and affordable, the Normcore Collection is a good place to look; if you're after the app, flow rate and the full experience, stick with Acaia. Not sure what suits your setup? Our advisory tool can help.
Frequently Asked Questions about the Acaia Orion Bean Doser
How fast and accurately does the Orion dose?
The Orion doses 225 grams in twelve seconds and 20 grams in three seconds, with a margin of error of just two to three beans. The speed depends on the target weight, and the system fine-tunes itself over time.
What do the Precise, Fast and Green modes stand for?
Precise is meant for small doses, Fast for large quantities from around 100 grams and Green for green coffee – for example for sample roasting or packing at the roastery. That way one device covers very different tasks.
How does the Orion differ from the Orion Mini and Orion Nano?
The Orion is the largest model with an approximately 20 cm platform and a 520 g hopper, designed for high throughput. The Orion Mini has a smaller 10 cm platform, the Orion Nano is the most compact version with a 500 g capacity and Orion's Belt for linking. You can find all three in our Acaia Collection.
Can I see the Acaia Orion before purchasing?
Our showrooms in Bern (Gerberngasse 44) and Zurich (Hagenholzstrasse 50b) show a wide selection, but not our entire range – the display changes. The Orion is often available to order – just drop us a line at [email protected] and we'll tell you the current availability.
Roastery tip
At our own cupping table, we appreciate how calmly the Orion lays down a row of identical doses. When we then pull espresso, we like to reach for Cozy Chocolate and Nutty Delight – full-bodied, sweet, dense. If you like it full and round without any acidity, stay with Very Nutty; for a fruity experiment, add Wild Peach. That's our recommendation, one of many, and any bean you enjoy is the right one.
