The Carolina Reaper is a cultivar of the Capsicum chinense plant. It is red and has a gnarled, lumpy pod with a tail like a scythe. In 2013, Guinness dubbed it the hottest chilli in the world, surpassing the previous record holder, the Trinidad Scorpion "Butch T". The official Guinness World Record heat level is 1,569,300 Scoville Heat Units (SHU). The figure is an average for the tested batch; the hottest individual pepper was measured at 2.2 million SHU.
