Yes in my opinion dried Carolina Reapers peppers just like any other dried hot peppers are hotter than fresh Carolina Reapers or fresh peppers.
For some reason the drying process of the Carolina Reaper peppers as well as any other type of hot peppers makes the peppers hotter than they would be when fresh.
My neighbor used to hang out hot peppers on her porch in the sun to get them dried out and the longer they would hang out on her porch in the sun and the more dried out they got the hotter those peppers would become.
I'm not sure exactly why and I forgot what she said about them getting hotter when drying them out but all I know is she said that drying the peppers out made them hotter.
