Power meets flexibility with more options than ever, such as standard or counterflow mode, additional airflow control, or roast at lower temperatures.
Optimized airflow in counterflow mode sends heat directly to the heart of the beans, giving you maximum efficiency and an option for low power use.
Improved temperature probe placement and a new pressure sensor unlock even greater precision and control over every roast.
Upgraded 5GHz WiFi ensures a super smooth user experience with faster, more stable connectivity.
More coffee, less work

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.
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.
Web portal
Get the most out of your roasting session with the ROEST Web Portal, designed to enhance your roasting and provide valuable data about your coffee. All roasting data is stored in the cloud and available from anywhere in the world via your web browser.
Updated touch screen interface
The L100 Ultra features a brand new touchscreen and interface, designed for better readability, more insights and a smoother user experience. Every detail has been refined for a seamless roasting experience.
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.
