The hottest pepper on the chart, officially, is the Carolina Reaper with a SHU of 2.2 million. It won the Guinness World Record in 2018, although it could have some competition from Pepper X which has an unofficial SHU of 3.18 million. It's still awaiting verification from Guinness World Records to be the official hottest pepper.
