Understanding the Scoville Scale (SHU)

Introduction

The Scoville Scale (SHU) is the standard measurement for the spiciness of chili peppers and spicy foods. Developed by Wilbur Scoville in 1912, this scale measures the concentration of capsaicinoids, the compounds responsible for heat. Whether you're a fan of mild peppers or extreme heat, this guide breaks down the spiciness levels and which chilies fall into each category.

How Capsaicin Works & Why Some Peppers Are Hotter

Capsaicin binds to pain receptors in your mouth, sending signals to your brain that interpret it as heat. The higher the concentration of capsaicin, the hotter the pepper feels. Factors that affect heat levels include: ✅ Pepper variety and genetics.
✅ Growing conditions (climate, soil, water levels).
✅ Maturity at harvest (fully ripened peppers are hotter).

How to Reduce the Heat of Chili Peppers

🔥 Remove the Seeds & Membrane: Most capsaicin is concentrated in the white pith.
🔥 Soak in Milk or Citrus Juice: Dairy and acid help neutralize spice.
🔥 Cook the Peppers: Heat breaks down capsaicinoids, reducing intensity.
🔥 Balance with Sweet or Fatty Ingredients: Sugar, honey, or oils mellow out the burn.

Comparing Your Hot Sauces to the Scoville Scale

If you're making your own hot sauces, understanding where your sauces fall on the SHU scale helps with branding and customer expectations. Here’s a rough guide:

🌶 Mild Sauces (1,000 - 5,000 SHU): Made with jalapeños or banana peppers.
🌶 Medium Sauces (5,000 - 50,000 SHU): Serrano or cayenne-based sauces.
🌶 Hot Sauces (50,000 - 250,000 SHU): Habanero and Scotch bonnet blends.
🌶 Extreme Heat (500,000 - 3,000,000+ SHU): Ghost pepper, Carolina Reaper, and Pepper X sauces.
