The Carolina Reaper is The Hottest Chili Pepper in the World
The Guinness Book of World Records has recognized the Carolina Reaper chili pepper as the world’s hottest chili pepper. We have a new record holder! Smokin’ Ed Currie of Puckerbutt Pepper Company, LLC was notified today that it was official.
With a Guinness-submitted 1,569,383 SHU (scoville heat units) average and recently measured peak levels of over 2,200,000 SHU, SMOKIN’ ED’S CAROLINA REAPER® has officially completed its long journey to the top of “super-hot” chili charts.
This is an extremely hot variety developed by a grower named Ed Currie. It is also called HP22B pepper. As of 2013 it is over 7 generations old. Ed created this chili pepper plant variety by crossing a Pakistani Naga with a Red Habanero type from St Vincents Island in the West Indies.
The flavor is fruity and similar to a 7 Pot chili pepper. The Carolina Reaper can grow to a height over 4 feet tall.
Are There Any Peppers Hotter than the Carolina Reaper?
There are some peppers reported to be hotter than the Carolina Reaper, but none have been officially recognized. Those peppers are the Dragon's Breath Pepper (announced in 2017, measuring in at 2.48 Million SHU), Pepper X (also developed by Ed Currie, announced in 2017, measuring 3.18 Million SHU), and the Apollo Pepper (also developed by Ed Currie, announced in 2022, measuring around 3 Million SHU).

About the Trinidad Scorpion Butch T Chili Pepper

The growers named the pepper the "Trinidad Scorpion Butch T", after Butch Taylor, who propagated the chili peppers in 2011. This chili pepper is the possible cross between a Trinidad Scorpion and as as-yet-named chili pepper that Butch is holding close to his chest in hopes of creating even hotter peppers in the future.
The Trinidad Scorpion Butch T measures in at a blistering 1,463,700 Scoville Heat Units (SHU). A typical jalapeno pepper measures around 5,000 SHU, while a habanero pepper measures up to 350,000 SHU.
