ROEST Batch Size, Power, and RoR Management

Batch size can be treated as a power-management variable on ROEST. One community member suggested adjusting batch size to make sure the machine has enough power available for the roast style being targeted. Treat this as community profiling advice rather than a fixed rule, because suitable batch size depends on coffee, roast level, environmental conditions, and machine behavior. source

Example Heat-Soak and Drying Approach

One user reported using about 30% heat for a 1-minute heat soak, then increasing to 75% or 80% heat through drying. This is a user-reported profile approach, not a universal recommendation; it should be adapted to batch size, green coffee, desired roast style, and observed RoR/bean-temperature response. source

Early Peak RoR and End-of-Roast Crash

A user connected avoiding an excessive early peak RoR with reducing the risk of a RoR crash near the end of the roast. In practical terms, this frames the beginning of the roast as important for later momentum: pushing too aggressively early may contribute to instability or loss of momentum later. Treat this as community interpretation and verify against actual roast curves and cup results. source
