Why ROEST?
Turn green coffee
into great coffee
ROEST reduces your workload while you sample roast.
We help you achieve the highest quality results with consistency, batch after batch.
-
First Crack Detection listens for individual cracks and identifies and registers the First Crack event. After the event is recorded, the roaster starts counting down the development stage and automatically releases roasted beans when complete.
First crack detection
An innovative solution to improve consistency and roasting knowledge. This technology turns ROEST into a fully automated roaster that ensures each coffee reaches its full flavor potential regardless of skill.
Roasting in 2 steps
-
When you drop green beans in, the sample roaster follows your profile from start to finish with digital precision. Our AI solution identifies and registers First Crack for you. After reaching the ideal development time, beans are automatically released for a final cooling process.
-
As soon as the beans drop, the machine is ready for the next batch. After 90 seconds, your beans are cooled down and you can collect your first batch of coffee.
