Correct !
Carolina Reaper is hotter, and is known as hottest current pepper !
Hotness is measured in 'scoville units' ( of heat), and the Carolina Reaper is the hottest !(over 2 million scoville units).
YEP Reapers are hotter by a lot. Ghost, 1,200,000 heat units. Reapers are at 2,400,000. Scoville scale.
For you novices Jalapenos rate at 2,000 heat units.
My wife canned some hot sauce with the Reapers and they are eating through the jar lids.
Ghosts are great in chili.
