The Reigning Hottest Chilli Pepper Guinness World Champion: The Carolina Reaper 

The Carolina Reaper has long been known as the hottest chilli pepper in the world. Developed by Ed Currie of PuckerButt Pepper Company, this chilli pepper boasts an average Scoville Heat Unit (SHU) rating of 1.6 million.

Some individual peppers reach an incredible 2.2 million SHU (pure capsaicin is rated at 16 million SHU).

Due to its distinctive appearance and intense heat it has captivated chilli fans worldwide, making it a staple in competitive eating challenges and ridiculously spicy food recipes.

Hottest Chilli Peppers - 7Pot Primo or Carolina Reaper

Carolina Reaper Controversy

But all may not be as it seems in the history books. There’s a lot of controversy surrounding the Carolina Reaper. 

Below are a few statements made by Ed Currie, which include inconsistencies, these as well as other reports I’ve read over the years is what makes me question its legitimacy as the Hottest Chilli Pepper:

On the Origin of the Carolina Reaper:

August 21 2012 “I will say that they are Asian/Sub-Asian descent and both are HOT.”

September 2013 “It was by trying to grow a sweet pepper that Currie claims he accidentally created the world’s hottest.” “Currie knew he had something special as soon as he laid eyes on the Reaper—it was the first pepper he’d even seen with a stinger.”  The Atlantic

December 2013 – “Ed Currie took a sweet hot pepper from the Caribbean and worked to make it hotter.” Daily Mail

December 2014 – “They were a Soufriere pepper from the Caribbean island of St. Vincent and a Naga pepper from Pakistan.” Los Angeles Times

The Hottest Chilli Pepper Rival: The 7Pot Primo

Meanwhile, in 2005, at Lafayette’s Horticulture Department, at the University of Louisiana, Troy Primo developed the 7Pot Primo™. And its Scoville rating is between 1.2 and 1.9 million SHU (Scoville Heat Units), which makes the 7Pot Primo arguably (and controversially) the Hottest Chilli Pepper in the world! Its one spicy pepper, believe me!

Interview with Troy Primo

At the end of 2022, I got to ask Troy Primo a little more about the controversial backstory surrounding the 7Pot Primo and Carolina Reaper.

Hottest Chilli Pepper - Troy Primo Interview

Troy Primo: “The 7Pot Primo beat Butch T (the world’s hottest pepper at more than 1.4 million Scoville in 2011). And then, shortly after, there was a guy named Ed Currie that came out with the Caroline Reaper. And I’m like, this looks a lot like the 7Pot.

All I can say is that I’ve stuck to my story. One story, and you know the other story has changed.

Meeting Ed Currie

When I met Ed for the first time in Lafayette, we had a festival. I don’t even remember what year that was, 2015, maybe. I met Butch T, Ed Currie, Jim Duffy, John Hard, and Gary Montcalm. And when I met Ed, he told me he had bought Naga seeds from me. And I couldn’t find any record of that. I looked it up because I was curious. Well, he told me a few things horticulturally, like some of his practices, that I just scratched my head on. 

I just want people to know at the end of the day, I know I can’t please everybody. And I shouldn’t even try. But I don’t lose any sleep at night over this. You can draw your own conclusions.

If you’ve got a cross, be very protective of it. Once they leave your backyard, all bets are off. Just know that if you do hand it out or sell it, then you have to face any kind of consequences that may happen. 

I pride myself on being consistent.” 

The 7Pot Primo is a cross between a Trinidad 7pot and Naga Morich. And, there’s a lot of love in the chilli community for this rival super-hot chilli pepper. 

“The 7Pot Primo chilli is a cross between a Trinidad 7Pot and a Naga Morich. It was a naive attempt as a student, but it turned out to be something special.”

Interview with Johnny Scoville

Here’s an excerpt from a recent interview I did with Johnny Scoville:

PXL 20230529 160412784
7Pot Primo Growing in ChilliChumps Greenhouse

“It’s amazing. And the work he’s done to get the pod to where it is! If you look at how stable his pods are, if you walk by a row of 7Pot Primo plants, those pods are so uniform. That is a wickedly stable pepper. 

ChilliChump: “I’m growing one in a hydro system. It is a beauty, leaves that are bigger than my hands. Wow, they look amazing. I can’t wait to get some proper pods.”

Johnny Scoville: “I’ll tell you what, we have a couple kilos of 7Pot Primo powder at our office – orange, so vibrant looking, it’s a beautiful thing.” 

Hottest Chilli Pepper: What’s Hotter than the Carolina Reaper? 


ChilliChump: “The hottest pod that I’ve eaten is the Primotali Chocolate – I’ve done that on video on a live stream which was stupid because it just shut me up for about 10 minutes.” 

Johnny Scoville: “Well, that’s really working without a net! Chris Saunders needs a shout-out from the UK; he’s the creator of that pepper. It’s a stupid hot pepper, 7Pot Primo cross with a Yellow Fatali.” 

ChilliChump: “I keep getting asked, what’s the hottest thing you have (chilli seeds) and the Primotali Chocolate is it. I mean, I have some hotter – 7Pot Primo is a classic, and it’s a tasty one. But the Chocolate Primotali is just pure heat; there’s nothing redeeming about it.

Everyone wants to know: is the Reaper the hottest? I said the first year I started my channel, it wasn’t the hottest. It wasn’t. There was hotter stuff then… Hands down [the Chocolate Primotali] has a very, very evil burn.

Johnny Scoville

ChilliChump: “And it builds; it just keeps building.” 

Johnny Scoville: “It really does; it’s got legs, it’s ferocious.”

Hottest Chilli Pepper: The Ghost Pepper/Bhut Jolokia

The Ghost Pepper, or Bhut Jolokia was known as the hottest pepper in the world according to Guinness World Records. This kicked off the race to the top with superhot chilli peppers (chilli peppers rated over 1 million Scoville).

Other notable Super-hot record holders are Infinity, Trinidad Moruga Scorpion, Naga Viper, Trinidad Scorpion Butch T and then the Carolina Reaper.

ChilliChump: “Do you remember the first time you had something seriously hot? For me, it was the Ghost Pepper, the Bhut Jolokia in 2006. Do you have a vivid memory of something that really took it up to that next level?”

Johnny Scoville: “Okay yeah, probably Ghost because I went from eating Habaneros to Ghosts, and you know it’s just a significant jump in heat, and it’s just like wow. A very, very serious jump that really got my attention. So that was probably the first real attention-getter.” 

ChilliChump: “There was just so much mystique about it at the time. For me, Scotch bonnets were considered hot, and I grew these Bhut Jolokias – I managed to get a few seeds when all the hype was big, and everyone was talking about how hot this thing is. It’s ridiculous, and it took me ages to actually eat it. I think my cousin Tony was the first one to try it from my plant. And I thought, oh, I have to have it now, it didn’t disappoint, but when you compare it to what you have today, I mean I have probably 50 varieties that are hotter than that in my greenhouse right now.” 

The Scoville Scale: Measuring Heat Intensity 

To understand the heat levels of chilli peppers, we turn to the Scoville Scale. Created by pharmacist Wilbur Scoville in 1912, this scale measures the concentration of capsaicinoids, the compounds responsible for the chilli pepper’s heat. Which means, the higher the Scoville Heat Unit (SHU) rating, the hotter the chilli pepper.

The Scoville Scale is a subjective measure of the pungency or heat of chilli peppers. It is determined by conducting a taste test and dilution process. In the original method, Scoville used a panel of taste testers who would sample a chilli pepper extract and report when the heat became undetectable. The measurement is then based on the number of dilutions required to reach this point.

For example, if a pepper extract had to be diluted 100 times before the heat became undetectable, it would be rated at 100 SHU. The scale has since been updated and improved with more accurate and scientific methods, including the use of high-performance liquid chromatography (HPLC) to directly measure capsaicinoid concentrations.

But, the heat levels on the Scoville Scale can vary widely. Even the mildest peppers, such as bell peppers, have a very low rating or no heat at all. In contrast, the hottest peppers, like the Carolina Reaper or the Trinidad Moruga Scorpion, can reach over 2 million SHU.

However, the Scoville Scale provides a useful reference to understand the heat intensity of different chilli peppers and helps people determine which level of spiciness they can handle. 

If So Many Chillies are Hotter than the Carolina Reaper, Why Does it Still Hold the World Record? 

Johnny Scoville: “I can think of eight to ten pods, just like that, that are hotter than the Reaper, for real.

We’ve gotten to a place now that when you say Carolina Reaper, so many people think of a person instead of the pepper, and when you think of the 7Pot Primo, people think of the person instead of the pepper. 

Listen, the very first year I started the channel, I ate the 7Pot or the Reaper, and I said it’s the hottest pepper in the world, but there’s a little asterisk by its name. There are a lot of other peppers that are hotter; it’s just the one that’s recorded in the Guinness World Record book.” 

ChilliChump: “There are a few things that people don’t realise.with Guinness; you have to pay a decent amount of money to get that title. Someone like Troy Primo is not going to spend that money.” 

Johnny Scoville: “Once you submit a chilli pepper with them, if it is a winner, you have to pay them tens of thousands of pounds per year to be able to claim it. If you don’t pay them and you claim you have a record, they sue you into oblivion. 

If you look at Chris Saunders, he’s growing in his backyard; he has a normal life, and he’s not going to throw 25 grand at a hobby. That’s really what it comes down to. The truth is there have been peppers that have tested hotter.” 

Hottest Chilli Pepper – What’s Next?

The Pursuit of a New Hottest Chilli Pepper

The chilli pepper community is constantly pushing the boundaries in search of even hotter peppers, by crossing chillies and selectively breeding them. And several contenders have emerged in recent years, vying for the world’s hottest chilli pepper title. For instance, here are a few notable chilli peppers that have generated buzz in the quest to dethrone the Carolina Reaper:

Is the Pepper X Real?

Developed by Ed Currie, the creator of the Carolina Reaper, Pepper X gained attention for its claims of surpassing the Reaper’s heat. Although specific SHU ratings have not been officially disclosed, early reports suggest it may reach an unprecedented 3.18 million SHU. But even this chilli pepper has courted controversy, with some people suggesting it is just the Big Mustard Mama, another chilli developed by Troy Primo.

Whats the deal with the Dragons Breath Chilli?

Originally claimed to be the world’s hottest chilli, Dragon’s Breath garnered significant attention. However, later tests revealed that it did not surpass the Carolina Reaper’s heat levels, casting doubt on its claim to the throne.

Chocolate Bhutlah

This chilli pepper gained popularity for its rich, earthy flavour profile and intense heat. While not surpassing the Carolina Reaper, it remains highly sought after by chilli enthusiasts.

The Impact of Super-Hot Peppers

    Why you say you need to pay 25 grand to get your tittle? As far as I could read you pay your expenses, that would be the growing and the testing and you get a free certidicate if you hold a new tittle, only pay for extra certificates. But thats what I read on the guineas faq, could you provide evidence for otherwise?

    1. There is a lot more to the process unfortunately, especially when it is done for commercial purposes. Guinness has a special section on their website just for this:
      Additionally to verify the record, you need to pay for a Guinness Judge or Adjudicator to come to your location (flights, hotel stay, local transport). There is a per year fee to be able to use the Guinness name. It all adds up.
      You can read more information here:
      Quote: “While any person can theoretically send in a record to be verified for free, the approval process is slow. Would-be record breakers that paid fees ranging from US$12,000 to US$500,000 would be given advisors, adjudicators, help in finding good records to break as well as suggestions for how to do it, prompt service, and so on.”
