The Scoville Scale,
Decoded for Cooks.
A Scoville database for 18 peppers: heat ranges, jalapeño comparisons, flavor notes, and best uses — grouped from sweet to superhot. Free, no sign-up.
True SHU Ranges
From zero-heat Bell Pepper (0 SHU) to weaponized Carolina Reaper (2,200,000 SHU).
Capsaicin Chemistry
Why water spreads the burn and casein in dairy proteins binds to capsaicin receptors to extinguish fire.
Culinary Pairings
Fruity habaneros for mango salsas; earthy jalapeños for pickling; smokey poblanos for stuffing.
ScovilleIndex Database
Bell Pepper
The zero point of the Scoville scale: crisp, sweet, and grassy — available in a color gradient that changes flavor more than heat.
Poblano
Mexico's mild poblano: earthy, barely warm, and famous twice — fresh as the relleno pepper, dried as the ancho chile.
Banana Pepper
Mild yellow wax pepper: tangy-sweet with a whisper of heat — the sandwich and antipasto ring standard.
Jalapeño
The world's reference pepper: green, grassy, medium heat — and the source of chipotle when smoked and dried.
Serrano
The serrano runs 2–4× jalapeño heat in a smaller, thinner-walled pod — the salsa pepper that skips the peeling step.
Fresno
Red, conical, and jalapeño-adjacent: fruitier flesh that makes the pickled Fresno ring the burger standard.
Cayenne
The thin, red, dried-and-ground workhorse: cayenne powder and pizza-joint red pepper flakes are this pepper, everywhere.
Thai Chile (Bird's Eye)
Small, red-or-green, and violently bright: the bird's eye chile behind Thai, Lao, and Vietnamese heat levels.
Habanero
The habanero's lantern shape hides the most fruity flavor in hot peppers — apricot-tropical notes at 100× jalapeño heat.
Ghost Pepper (Bhut Jolokia)
India's Bhut Jolokia held the world record (2007): slow-onset, long-lasting heat at 800k–1M SHU with a smoky-sweet side.
Carolina Reaper
The current Guinness record holder (1.64M average): a scorpion-tailed pod with fruity lead notes and industrial-grade fire.
Trinidad Moruga Scorpion
The Moruga Scorpion held the record (2012): genuine butterscotch-citrus flavor notes beneath two-million-SHU potential.

What Capsaicin Actually Does: The Chemistry of "Hot"
Peppers are not hot in temperature — capsaicin binds a heat receptor and tricks your nerves. The TRPV1 story, and why milk works.
Taming Heat in Cooking: What Actually Reduces Capsaicin (and What Myths Say)
Dairy at the table, sugar in the pot, and the seeds-and-veins question — the kitchen levers that control heat, ranked.
Why the Same Pepper Varies 50% in Heat: Stress, Sun, and Seed Lineage
The jalapeño that bites like a serrano is real — drought stress doubles capsaicin. The growing variables behind every SHU range.
