Key Takeaways
- ✓Scoville Scale Origins: Wilbur Scoville's 1912 organoleptic test measured pepper heat by diluting extract until tasters detected no burn, assigning that dilution ratio as Scoville Heat Units. Modern labs now use high-performance liquid chromatography, where one part per million capsaicinoids equals roughly 16 SHU.
- ✓Pepper Heat Progression: Jalapeños range 2,500–8,000 SHU, habaneros reach 100,000–350,000 SHU, and the current record holder, Pepper X developed by Ed Currie in 2023, measures 2,600,000 SHU — a 169% increase over the 2007 ghost pepper record of roughly one million SHU.
- ✓Spice and Food Preservation: Researchers Sherman and Billing found cuisines from hotter climates use more antimicrobial spices, particularly in meat dishes, because bacteria reproduce faster at higher temperatures. Capsaicin carries antimicrobial properties, suggesting spiced cooking historically reduced foodborne illness before refrigeration existed.
- ✓Taxonomy Clarification: Bell peppers and jalapeños are different varieties of the same species, capsicum annuum, while habaneros belong to capsicum chinense — a separate species. At least five capsicum species were independently domesticated across different regions of the Americas, making "pepper" a broad, often misleading category.
What It Covers
Capsicum peppers originated entirely in the Americas, spread globally via Portuguese and Spanish trade routes after 1500, transformed cuisines across India, Asia, and Africa, and now represent a $77 billion worldwide market projected to exceed $120 billion by 2034.

Notable Moment
Bell peppers are not a distinct plant — they are jalapeño-type peppers selectively bred to carry a genetic mutation eliminating capsaicin production, with red bells simply being the same fruit allowed to fully ripen, developing greater sweetness.
Episode Transcript
For thousands of years, humans in The Americas have cultivated an extremely hot plant. When it was transferred to the old world, it transformed cuisines, inspired scientific measurements, and made some meals much, much, much hotter. Its story stretches from the ancient Americas to kitchens on almost every continent today. Learn more about the surprisingly hot history of peppers on this episode of Everything Everywhere Daily.

Before we get too far into peppers, we have to clarify exactly what we're talking about, because the word pepper applies to several different types of plants. The word pepper originally applied to spices such as black pepper or long pepper. Likewise, Sichuan peppers from China are another wholly unrelated plant that carries the same name. All of these plants are not related to the subject of this episode. The topic of this episode will be capsicum peppers, or members of the genus capsicum. And what all these plants …
