Great feedback ! Which quantity of beans for these roast ? 250g 230g ?
I'm surprised that you didn't change the temperature even after the FC, with my Gene Roaster, if I don't reduce it, after 1 to 1,5min there is the SC !
From my little experience on this device and in roasting (30kg until now), higher the batch quantity is, quicker the temperature raise - Depending the beans used (SHB for instance) It could be difficult to handle the power/temperature this is why I tend to manage it by reducing the batch quantity.
