The Scoville Scale Explained
Before we talk further about Thai chili peppers, it’s essential to understand the Scoville Scale (if you already know all about it, you can skip to the next section). The Scoville Scale is a measurement system created to rank the spiciness of peppers based on their capsaicin content (the compound that produces heat).
Here’s how Thai chili peppers stack up:
Thai chili peppers: 50,000 - 100,000 SHU (Scoville Heat Units)
Jalapeño peppers: 2,500 - 8,000 SHU
Habanero peppers: 100,000 - 350,000 SHU
Carolina Reaper (the hottest pepper): Over 2,000,000 SHU
This ranking shows that Thai chili peppers are in the mid-to-high heat range, making them an excellent choice for those who enjoy fiery spice without overwhelming heat.

Types of Thai Chili Peppers
One of the common misconceptions about Thai chili peppers is that they are a single variety. This is most likely due to most people only seeing the one kind in your common grocery stores.
However, there are numerous types, each with its own heat level and culinary purpose.
Here are some of the most notable ones:
Prik Kee Noo (Bird’s Eye Chili): Famous for their intense heat, these are the most commonly used in Thai dishes.
Prik Chee Fah (Sky‐Pointing Chili): Milder than bird’s eye chilies, these are often used for aesthetics and color in dishes.
Prik Jinda (Long Red Chili): A moderately hot variety, they’re great for creating a balance of spice and flavor.
Prik Yuak (Mild Thai Chili): Perfect for those who prefer a sweet and subtle level of spice.
Heat Levels of Thai Chili Peppers
To better understand the heat levels of Thai chili peppers, here’s a simple chart comparing their Scoville Heat Units (SHU) and typical uses:
Pepper Name | Heat Level (SHU) | Common Uses |
Prik Kee Noo | 50,000 - 100,000 | Stir-fries, curries, and dipping sauces |
Prik Jinda | 50,000 - 75,000 | Balance of spice for soups, marinades, and sauces |
Prik Chee Fah | 5,000 - 7,000 | Garnishes, adding color, and milder spicy dishes |
Prik Yuak | 0 - 1,000 | Mild dishes, salads, and decorative purposes |
