The world’s first sample roaster with automatic first crack detection

This AI-driven technology detects and records first crack by sound, allowing precise control of development time and ensuring each coffee reaches its full flavor potential with minimal intervention.

By identifying first crack exactly as a human would—based on sound—the system allows you to focus on other tasks while maintaining accuracy.

How it works

ROEST uses advanced AI to detect the sound of individual beans cracking, distinguishing it from background noise inside the drum. The built-in microphone continuously monitors the roasting process, marking each crack on the roasting curve.

The system then automatically drops the batch based on the predefined development time or ratio, ensuring consistent and repeatable roasting outcomes.
