The Paqui “One Chip Challenge” is extremely hot, but not quite at the raw pepper’s top advertised numbers once you look at actual tests.

Short answer

Most lab-style measurements put the Paqui One Chip Challenge chip itself around 50,000–60,000 Scoville Heat Units (SHU) , which is similar to a very hot habanero sauce, but the peppers used (like Carolina Reaper) can reach over 2,000,000 SHU in pure form. Other branded “one chip challenge” products (like Fiery Jack’s) claim up to 16 million SHU , which is at the theoretical top of the Scoville scale and far beyond typical chili peppers.

How hot is it in Scoville?

  • A food science test using a capsaicin analyzer measured the Paqui One Chip Challenge at about 56,000 SHU for the chip you actually eat.
  • This is roughly:
    • 10× hotter than a mild jalapeño (around 5,000 SHU).
* In the range of a strong habanero sauce, though milder than eating pure habanero or reaper peppers.

However, the ingredients on the chip are much more intense than that number suggests:

  • Carolina Reaper powder on the chip comes from peppers rated around 2.2 million SHU.
  • Earlier versions used peppers like Carolina Reaper and Naga Viper, which themselves are typically listed at 1.4–1.7 million SHU.

That’s why packaging, marketing, and online chatter often quote “up to 2+ million SHU” – they’re referring to the pepper extract, not the final diluted chip.

Other “one chip” products

Not all “one chip challenges” are the same product:

  • A UK product, Fiery Jack’s One Chip Challenge , is marketed as the “world’s spiciest chip” at 16 million SHU , essentially the top of the scale used for pure capsaicin.
  • Claims like this are about the added extract , and the real perceived heat can vary a lot person to person, but on paper it’s vastly hotter than jalapeños or even reaper peppers.

Because of that, how hot “the one chip challenge” is depends on which brand and batch someone is talking about.

What it feels like (from reports)

People who do the Paqui-style challenge commonly describe:

  • Immediate, intense burning in the mouth and throat.
  • Strong stomach discomfort, sometimes cramps or nausea, especially on an empty stomach.
  • A “wave” pattern: unbearable for several minutes, then slowly fading after 20–60 minutes, though stomach issues can linger longer.

Forum megathreads show many users saying they regretted it afterwards, even if they handled other spicy wings or sauces before.

Safety and health notes

Health organizations and hospitals have warned about the challenge, especially for kids and teens:

  • The chip uses extremely hot peppers, and capsaicin in high doses can cause severe pain, vomiting, and in rare cases more serious complications.
  • Medical advice is generally:
    • Avoid it if you have heart, stomach, or digestive issues.
* Do not let children participate.

* If someone has chest pain, trouble breathing, or symptoms that don’t calm down, seek medical help.

So while the measured heat of some Paqui chips (around 56,000 SHU) might look lower than the hype, the combination of concentrated chili powders, eating it all at once, and trying to “last” without relief makes the experience feel brutally hot for most people.

Quick comparison table

Item Approx. SHU Notes
Jalapeño pepper 2,500–8,000 Common “spicy but manageable” chili.
Paqui One Chip (tested) ~56,000 Measured chip heat, not raw pepper rating.
Carolina Reaper pepper Up to ~2,200,000 Powder used on some one-chip products.
Fiery Jack’s One Chip Challenge ~16,000,000 (claimed) Advertised using pure capsaicin-level heat.
**TL;DR:** In practical terms, most people will experience the One Chip Challenge as “insanely hot, worse than any normal hot sauce,” even though lab tests put some versions around 50–60k SHU and the 2M+ (or 16M) figures refer to the peppers or extracts rather than the chip as a whole.
