What is the Scoville Scale?

The Scoville Scale was invented in 1912 by American pharmacist Wilbur Scoville. It measures the heat level of chili peppers based on their capsaicin content — the compound responsible for that burning sensation. The unit of measurement is called the Scoville Heat Unit (SHU), which reflects how much sugar water it would take to dilute the heat until it’s no longer detectable.

Scoville Scale Chart

For example:

  • A bell pepper has 0 SHU — zero heat.
  • A jalapeño clocks in around 2,500–8,000 SHU — spicy enough to make your eyes water a little.
  • A ghost pepper (Bhut Jolokia)? Over 1,000,000 SHU — not for the faint of heart.

Let’s explore some of the most popular peppers categorized by their heat level. This will help you decide whether you want to warm up your tacos or challenge your friends with an “eat-or-dare” daredevil dish.

7 Practical Tips for Handling Hot Peppers

Whether you're cooking with habaneros or just slicing a jalapeño, safety first! Here are seven tips to keep your kitchen experience pain-free:

  1. Wear gloves when handling super-hot peppers. Capsaicin sticks to skin and causes irritation.
  2. Use a sharp knife — dull blades bruise peppers, releasing more capsaicin into the air and onto surfaces.
  3. Don’t touch your face, especially your eyes. Trust us, it burns.
  4. Rinse peppers under cold water before cutting to reduce surface oils.
  5. Pair with dairy (like yogurt or sour cream) if eating hot dishes — capsaicin dissolves in fat, not water.
  6. Add acid (lime juice or vinegar) to balance heat and enhance flavor.
  7. Store dried chilies properly in airtight containers away from sunlight to preserve flavor and potency.
