From Bell Pepper to Carolina Reaper: The Scoville Scale Heat Rankings
If you’re curious about how spicy your peppers really are, understanding the Scoville Scale is the key. This scale measures the heat level of chili peppers based on their concentration of capsaicin — the compound responsible for that fiery kick.
Whether you prefer the mild crunch of a bell pepper or the intense burn of a Carolina Reaper, this guide will walk you through the most popular peppers ranked by their Scoville Heat Units (SHU). Knowing the heat rankings helps you choose the right pepper for cooking, gardening, or even spicy challenges!
What Is the Scoville Scale?
Invented by Wilbur Scoville in 1912, the Scoville Scale assigns a heat value to peppers based on how much capsaicin they contain. The higher the number of Scoville Heat Units, the hotter the pepper.
-
Bell Pepper: 0 SHU — No heat, just sweet and crunchy.
-
Jalapeño: 2,500–8,000 SHU — Mild to moderate heat, common in many dishes.
-
Habanero: 100,000–350,000 SHU — Significantly hotter, fruity and fiery.
-
Carolina Reaper: 1,400,000–2,200,000 SHU — The world’s hottest pepper, extreme heat.
