The Carolina Reaper has been officially dethroned as the world's hottest chilli pepper.
PuckerButt Pepper Company founder and pepper expert Ed Currie has spent the last ten years working on Pepper X, a chilli pepper that emits an "immediate and brutal heat," according to reporting by the Associated Press.
Five of those years were spent proving Pepper X was a different plant with a different fruit and documenting its average heat over different plants and generations.
