The Hottest Peppers in the World, and Who Held the Record When

The hottest pepper in the world is a title that has moved six times in thirty years, and almost all of that movement is deliberate breeding rather than discovery. The peppers at the top of the scale today did not exist when the scale was last interesting.

The record-holder timeline

  1. to 1994Habanero ~225,000 SHU

    For most of the twentieth century the habanero was simply the top of the scale, and it was already far enough above everything else to seem like a limit.

  2. 1994Red Savina577,000 SHU

    A selectively bred habanero from California that more than doubled the record and held it for twelve years — the longest reign of any modern holder.

  3. 2007Ghost pepper1,041,427 SHU

    Bhut jolokia, from Assam in northeastern India. The first pepper confirmed above a million, and nearly double the Red Savina. It is a naturally occurring interspecific hybrid rather than a bred cultivar, which is why it arrived as a shock rather than an announcement.

  4. 2011Naga Viper1,382,118 SHU

    Bred in Cumbria, England, from a three-way cross. Unstable — the seeds do not reliably breed true — which is part of why its reign was measured in months.

  5. 2011Trinidad Scorpion Butch T1,463,700 SHU

    Named for the tail-like point on the pod. The people who prepared it for testing wore chemical masks and gloves.

  6. 2012Trinidad Moruga Scorpionup to 2,009,231 SHU

    Measured at New Mexico State University's Chile Pepper Institute. Notable less for the peak than for the shape of the burn: it builds for minutes rather than arriving.

  7. 2013–2023Carolina Reaper1,641,183 SHU average

    Ed Currie's cross of a ghost pepper and a Red Savina, in South Carolina. Its average is lower than the Moruga's peak, which is the point — Guinness moved to certifying averages across many pods rather than a single lucky fruit, and the Reaper is consistent in a way its predecessors were not.

  8. 2023–Pepper X2,693,000 SHU average

    Currie again, after ten more years of breeding. Sixty-four percent hotter than the Reaper, and roughly twelve times a habanero.

What actually makes a superhot different

Above about a million SHU, peppers stop behaving like hotter versions of the ones below them.

The onset is delayed. A Serrano announces itself immediately. A ghost pepper can take thirty seconds, which is long enough for someone to decide it was overrated and take a second bite. That second bite is the one that ends up in videos.

It builds rather than peaks. A jalapeño peaks within a minute and recedes. A Moruga Scorpion climbs for five, and the climb is what makes it frightening rather than the height.

The systemic response is real. Sweating, hiccups, watering eyes and a racing heart at these levels are ordinary autonomic responses to a strong stimulus, not signs of injury. What is worth taking seriously is that a large dose can trigger genuine vomiting, and that the abdominal pressure of that has caused rare but documented injuries. There is a reason every serious pepper-eating event has a medic.

Is there a point in training toward one?

Toward the ghost pepper, yes — plenty of people reach it, and it appears on menus in enough places that it is a real-world goal rather than a stunt. Past the Reaper, it stops being a tolerance and becomes an event. Nothing at 2,693,000 SHU is served with dinner.

The more useful ambition sits lower and gets used more often: the scotch bonnet in real jerk, the habanero salsa at the taqueria, a vindaloo cooked the way the kitchen eats it. Those are two-thirds of the way up the ladder and they change what you can order for the rest of your life.

Common questions

What is the hottest pepper in the world?

Pepper X, confirmed by Guinness World Records in October 2023 at an average of 2,693,000 Scoville heat units. It was bred by Ed Currie in South Carolina, who also bred the Carolina Reaper it replaced.

How hot is the Carolina Reaper?

An average of 1,641,183 SHU, with individual pods measured as high as 2,200,000. It held the world record from 2013 to 2023 and is a cross between a ghost pepper and a Red Savina habanero.

What counts as a superhot pepper?

By convention, anything above roughly 1,000,000 SHU — the threshold the ghost pepper crossed in 2007. Practically, superhots share a distinct behaviour: a delayed onset, a burn that builds for minutes rather than peaking immediately, and a fade measured in half-hours.

The ladder is more interesting than the top of it

Two thirds of the way up is where the food actually is — real jerk, the habanero salsa at the taqueria, a vindaloo cooked the way the kitchen eats it. That is the part worth training for.
