The world’s first sample roaster with automatic first crack detection–AI technology that identifies and registers first crack by sound.

Marking first crack automatically enables the roaster to control development time and tailor the length of each roast to the bean. This ensures each coffee can reach its full flavor potential with minimal oversight.

Identifying first crack based on sound ensures that the roaster registers first crack at the same moment that a human would while allowing the user to focus on other tasks.

HOW IT WORKS ?

ROEST developed unique AI technology that can pinpoint the sound of individual beans cracking and accurately distinguish it from all the other noise inside the drum.

The ROEST monitors the sound inside the drum with its onboard microphone, registers the moment that first crack begins—and marks every single crack on the roasting curve.

The roaster then automatically drops the batch based on the development time or development time ratio set in the profile.
