About KnowThePepper

A pepper encyclopedia written by people who grow peppers, cook with them, and care about getting the details right.

Why We Made This

We started KnowThePepper because the pepper information online was either too shallow or flat-out wrong. We'd see sites listing SHU numbers with no source, growing advice that didn't account for climate, and "comparison" pages that were just two paragraphs of filler.

We wanted something better: a place where you can look up a pepper and actually learn what it tastes like, how hot it really is (with a cited source), what to use instead if you can't find it, and how to grow it yourself. Right now we cover 219+ varieties with profiles, comparisons, growing guides, and substitution data.

How We Work

Heat data from real studies
Every SHU range traces back to USDA FoodData Central, a peer-reviewed paper, or a Guinness-verified measurement. If a number isn't sourced, we don't publish it.
Grown in our gardens
We've cultivated 200+ varieties across USDA zones 5 through 11. The growing tips on this site come from what actually worked — and what didn't.
Cooked in our kitchen
When we say you can substitute one pepper for another at a certain ratio, it's because we've done it. Recipes and culinary tips are tested before they go live.
No pages for the sake of pages
We don't publish thin content to pad our page count. If a page doesn't teach a reader something specific and useful, it doesn't belong on this site.

The Team

KnowThePepper is a small team: pepper growers, a food scientist, a trained chef, and a heat enthusiast who'd rather be in the garden or the kitchen than behind a desk. Between us, we've grown over 200 varieties, made more hot sauce than we can count, and argued at length about whether the Scotch Bonnet is better than the habanero (it depends on the dish).
