The Carolina Reaper HP22B, officially recognized as the world’s hottest chilli, holds the Guinness World Record with an average Scoville Heat Unit (SHU) rating of 1.5 million—and peaks surpassing 2.2 million. A fearsome hybrid between a Habanero and a Naga Viper, this Capsicum chinense variety was developed by Ed Currie in South Carolina. Known for its wicked tail-like tip and brutal, lingering burn, the Carolina Reaper is not just a test of heat tolerance but a must-grow legend for extreme chilli lovers.
