Flavor Profiles and Heat Levels

One of the most significant differences between chili peppers and bell peppers is their flavor profile and heat level. Chili peppers are known for their spicy heat, which comes from a compound called capsaicin. The heat levels of chili peppers can vary greatly, ranging from mild to extremely hot.

Exploring chili pepper varieties from mild to super-hot can help you find the perfect pepper for your palate. In contrast, bell peppers are sweet and mild, with no heat. They are often used in salads, stir-fries, and other dishes where a mild, sweet flavor is desired.

Scoville Heat Units

The heat level of chili peppers is measured using the Scoville scale, which measures the concentration of capsaicin in a pepper. The scale ranges from 0 (no heat) to over 2 million Scoville Heat Units (SHU) for the hottest chili peppers in the world. Bell peppers have a Scoville rating of 0, while mild chili peppers like jalapeños range from 2,500 to 8,000 SHU.
