The bloke at the Sawtell Chilli Festival has a name like a wrestling villain – Adam “the Chilli King” Connell – and he’s staring down pure capsaicin. Not a Carolina Reaper. Not a ghost pepper doused in Da Bomb. We’re talking actual capsaicin crystals; 16 million Scoville Heat Units (SHUs). They’re described as “not for human consumption”.
Welcome to the cult of capsaicin, where suffering is the point, and sambal is competitive sport. Connell isn’t the only one chasing the burn. Across Australia, from Broome to the Yarra Valley, thousands gather at chilli festivals to watch fully grown adults weep over chicken wings. At the Sawtell event, contestants work through 30 brutal rounds, beginning with a manageable habanero (200K SHUs) and ending – if they make it – at the torture of those capsaicin crystals. The prize? Bragging rights and a trophy… but the real reward? The onslaught of endorphins that follows the pain on a scale of nil to how-high-can-you-count.
The arithmetic of fire
American pharmacist Wilbur Scoville created the Scoville Scale in 1912. His method involved diluting chilli extract in sugar water until testers could no longer detect the heat. The more dilution required, the higher the Scoville score. For example’s sake, a friendly little capsicum has a zero rating, a jalapeño averages about 5000, a Scotch bonnet about 200,000 and those pepper sprays used for personal protection? They’re about 3.5 million. These days, Scoville Units are measured scientifically using high-performance liquid chromatography.
The festivalisation of fire
The pungent pepper scene evolved from chatty backyard barbecues with a splash of Tabasco to full-blown cultural events. The Herb & Chilli Festival in Wandin, Vicxtoria, draws a crowd of about 1300, with more than 80 stallholders slinging everything from Bhut Jolokia-laced honey (one million SHUs) to products with names like “Satan’s Spit”. At the Chilli in the Valley festival near Perth, contestants battle for $500 credit (only to be spent locally), and in Broome, at the slightly feral Matso’s chilli-eating competition, families pack rugs to watch the spectacle of endurance.
The hot sauce economy has professionalised, too, despite the faintly unhinged labels. Melbourne Hot Sauce has racked up awards from New York to Texas, which is not an easy market. The Gordon Ramsay approved fire serum, Bunsters Shit the Bed, claims it kick started Australia’s hot sauce revolution. Meanwhile, Fire Asstinguisher, made in Victoria, calls itself “the world’s first chilli aftercare product” and claims to soothe the aftermath of extreme chilli consumption – apparently milk does the same thing. And if proof were needed that hot sauce is now fully mainstream, Brooklyn Beckham has his own bottled heat, Cloud 23.
The heat elite
Sean Evans hosts Hot Ones, a YouTube phenomenon that makes progressively spicier flavour trials a legitimate celebrity interview format. The show’s been running for over a decade, amassing more than four billion views. As Evans puts it, “Celebrity is so unobtainable by definition. But what’s more ‘common man’ than dying on hot sauce?” He’s been across the table with everyone from Billie Eilish to Hugh Jackman, sweating through rounds of heat topping out at “The Last Dab”, 2.5 million SHUs – a chilli oil so brutal it’s actually a meme. The format works because spice is a great equaliser; it strips away the artifice. Watch someone famous lose their composure over wing number six, and suddenly they’re not so special.
Collectors talk about heat the way sommeliers talk about tannins. They discuss mouthfeel, burn quality, and the duration of the sensation. Good heat is described as clean. Bad heat is aggressive. This language attempts to civilise pain, to fold it back into the realm of taste. Sometimes it works. Sometimes it doesn’t.
Spice isn’t flavour
Here’s the thing: capsaicin doesn’t activate taste receptors; it activates pain receptors. Specifically, the TRPV1 receptor, a protein channel that detects potential tissue damage. When the heat floods your mouth, these pathways send distress signals to your brain: We’re on fire. Danger. Except you’re not. Your nervous system is tricked into believing you’re being burned. Your heart rate spikes, you sweat, you hiccup and sniffle, your nose runs. All of these are classic thermoregulatory responses to overheating.
But here’s where it gets interesting: after the panic, our brains release neurochemicals – natural opioids designed to dull pain. MRI studies show that capsaicin doesn’t solely activate pain centres; it also activates the prefrontal cortex (the attention and cognitive control HQ in our brains) and areas linked to reward processing. That rush you feel after polishing off a vindaloo? That’s your nervous system kicking in, flooding you with feel-good chemicals because you just survived a threat.
The psychology of heat-seeking
Psychologist Paul Rozin coined the term “benign masochism” to describe activities that trigger fear or pain in safe contexts – roller coasters, horror films, a quick polar plunge. Your body screams danger, but the brain knows everything is actually fine. It’s a thrilling contradiction. Research backs this up, too. Studies show that people who regularly consume spicy foods score significantly higher on measures of Sensation Seeking (women) and Sensitivity to Reward (men) – personality traits linked to thrill-seeking and pleasure-focused behaviour. It seems the flame chasers aren’t just tougher, they’re wired differently.
They’re hunting novelty, risk and reward, much like elite athletes do. There is a limit to what’s safe to ingest, and it’s different for everyone. Some of us are born with fewer TRPV receptors than others, or those that are less sensitive to the pain of heat. Others have receptor dense tongues that light up at the faintest whisper of chilli. Culture plays a huge part, too, of course. In societies where high spice foods are ubiquitous, like Mexico, Thailand, Korea, and India, children develop tolerance early because they’re exposed consistently and their receptors desensitise over time.
“If we can’t handle the heat, are we weak? Boring? Less adventurous? Like it or not, there’s a subtle social hierarchy at play.”
The cultural signalling of spice
There’s a reason people announce their spice tolerance, completely unprompted. Ordering the hottest thing on the menu isn’t just about flavour, it’s about identity. If we can’t handle the heat, are we weak? Boring? Less adventurous? Like it or not, there’s a subtle social hierarchy at play. The person who orders it mild is the person who plays it safe, but the one who goes for extra chilli? They live on the edge; they court excitement. This is reductive, of course. Spice tolerance is biological, not a personality trait. But the cultural framing persists, and it’s part of why chilli clubs and festivals have exploded.
The experience offers a story worth telling… the hottest sauce you survived, the night someone cried, the moment you realised you were part of the circle. Perhaps the real allure, in this age of distraction, is the immediacy. And, maybe it’s not something that needs to be understood to enjoy, especially for those who only observe. For some, pain isn’t a deterrent; it’s an invitation.
