The infamous Carolina Reaper chile pepper is the hottest pepper known to man. It has claimed that title with a whopping peak heat of 2.2 million on the Scoville scale. For reference, a habanero, which most will agree is plenty hot already, clocks in at less than 10% of the Reaper, at “only” 200,000 units. It’s also 200 times hotter than the downright measley jalapeno pepper. The average heat is a little more manageable at 1.6 million on the scale.
