Pepper Scoville Chart

Understanding the Pepper Scoville Chart. Peppers come in a dazzling array of shapes, sizes, and colors, but what truly sets them apart is their heat. The fiery sensation that peppers deliver is measured using the Scoville scale, a unit developed to quantify the spiciness of these vibrant fruits. In this article, we will explore the Pepper Scoville Chart, deciphering the scale to understand the heat levels of various peppers and gaining insights into why some peppers are hot, while others are mild.

What is the Scoville Scale?

Named after its creator, American pharmacist Wilbur Scoville, the Scoville scale measures the concentration of capsaicin, the chemical compound responsible for the pungency in peppers. Capsaicin binds to receptors in our mouths and on our tongues, sending signals to the brain that are interpreted as heat. The higher the Scoville rating, the hotter the pepper.

Understanding Scoville Ratings

  1. Sweet Peppers (0-1,000 Scoville Units): Sweet peppers like bell peppers and banana peppers have little to no heat. They are widely used in cooking for their mild, slightly sweet flavor.
  2. Mild Peppers (1,000-15,000 Scoville Units): Peppers in this range, such as poblano and cherry peppers, offer a gentle kick without overwhelming spiciness. They are often used in various cuisines to add a subtle heat.
  3. Medium Peppers (15,000-50,000 Scoville Units): Peppers like jalapeños and serranos fall into this category. They provide a noticeable heat that many enjoy, making them popular choices for salsas, sauces, and pickled dishes.
  4. Hot Peppers (50,000-100,000 Scoville Units): Peppers such as cayenne and Thai chilies bring a fiery heat that tingles the taste buds. They are used sparingly in cooking due to their potency.
  5. Very Hot Peppers (100,000-1,000,000 Scoville Units): This range includes peppers like the famous habanero. Consuming these peppers demands caution due to their intense heat, and they are often used in small quantities to add significant spice to dishes.
  6. Extreme Heat Peppers (1,000,000+ Scoville Units): At the top of the Scoville scale are peppers like the Carolina Reaper, currently the world’s hottest pepper. These peppers are not for the faint-hearted and are primarily used in hot sauces and pepper extracts.

Why Peppers Are Spicy

Peppers developed their spiciness as a defense mechanism against herbivores. Birds, unlike mammals, cannot taste capsaicin and thus are not affected by the heat. This makes them natural carriers of pepper seeds, aiding in the plant’s propagation.


The Pepper Scoville Chart serves as a valuable guide for spice enthusiasts and culinary experts alike. By understanding the Scoville scale, one can explore the world of peppers with confidence, selecting the perfect pepper for any dish. Whether you crave a subtle heat or a fiery explosion, the diverse range of peppers offers a thrilling culinary journey, adding depth and excitement to the world of cooking. So, the next time you savor a spicy dish, remember the Scoville scale and appreciate the complex chemistry that makes peppers hot.
