Buying a sample roaster
A ROEST Sample Roaster has everything you need to get started roasting, including a tray, hopper, sample tray, and 1.5m ventilation hose. Customers often add the 200 g kit with a larger tray and hopper extension, our Pelicase for easy transport, and a 90-degree elbow if you prefer it over the ventilation hose.
ROEST innovations explained
First crack detection
ROEST is 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.
-
Using a built-in microphone and advanced AI technology, the ROEST pinpoints the exact moment first crack begins, distinguishing the sound of individual beans cracking from other noise inside the drum. Every crack is mapped on the roasting curve the batch automatically drops the batch based on the development time or development time ratio set in the profile.
Advanced sensors
for precision control
ROEST’s cutting-edge sensor technology provides both accurate data and pinpoint control. Fast, responsive temperature probes and sensitive control algorithms ensure that ROEST sample roasters deliver repeatable and reliable results every time.
-
These systems work together to continuously monitor and adjust key roasting variables—such as temperature, airflow, and drum speed—ensuring every batch follows your profile with exacting accuracy.

Reversible drum
for counterflow mode
With the L100 Ultra, you can choose the direction of rotation for the drum. Standard mode enables you to use similar profiles and replicate the roast style of the classic S100/L100+ models.
In Counterflow mode, the drum rotates in the opposite direction, bringing the bean pile directly into the path of the airflow. In this mode, the L100 Ultra operates like a miniature version of our acclaimed P3000 production roaster.
-
Counterflow mode enables radically more efficient transfer of heat from the air to the beans, giving you the choice of roasting much faster, or achieving similar roast times at much lower temperatures. The result is roast profiles that are faster, more energy-efficient, and gentler on the beans.
Roasting profiles
Create new profiles based on air temperature, bean temperature, inlet temperature or power profiles. Or our web portal provides a library where you can share roast profiles and find existing ones. Get connected with our ROEST community and learn from each other by sharing profiles and experiences.
