What Is a Thai Chilli?

The Thai chilli, also known as bird’s eye chilli or *Capsicum annuum*, is a small but mighty member of the Capsicum family. Native to Southeast Asia, especially Thailand, this pepper has become a global kitchen staple thanks to its vibrant flavor and punchy heat.
Understanding the Scoville Scale

Invented by pharmacist Wilbur Scoville in 1912, the Scoville scale measures the spiciness of peppers using Scoville Heat Units (SHU). Originally based on human taste testing, modern methods use high-performance liquid chromatography to determine capsaicin content—capsaicin being the compound responsible for that fiery kick!
Thai Chilli Scoville Heat Range
Now, onto the main event. The **Thai chilli Scoville** rating typically ranges from:
- 50,000 to 100,000 SHU (depending on growing conditions, variety, and maturity)
To put that into perspective, it's hotter than jalapeños (2,500–8,000 SHU) and often matches or exceeds cayenne peppers (30,000–50,000 SHU).
Chilli | Scoville Heat Units (SHU) |
---|---|
Bell Pepper | 0 |
Jalapeño | 2,500–8,000 |
Serrano | 10,000–23,000 |
Cayenne | 30,000–50,000 |
Thai Chilli | 50,000–100,000 |
Habanero | 100,000–350,000 |

Common Myths About Thai Chillies Debunked
Let’s bust some myths floating around about Thai chillies:
- Myth: The seeds are the hottest part.
Truth: While seeds can contribute, the placenta (the white membrane inside the pepper) holds most of the capsaicin. - Myth: Milk makes it worse.
Truth: Milk, especially whole milk, contains casein which neutralizes capsaicin—great for cooling down your tongue! - Myth: Eating Thai chillies damages your stomach.
Truth: Unless you have a pre-existing condition, moderate consumption is safe and may even offer health benefits.
Want to Grow Your Own Thai Chillies?

If you’re feeling adventurous, try growing Thai chillies in your garden or balcony:
- Start with quality seeds and well-draining soil.
- Ensure 6–8 hours of direct sunlight daily.
- Water regularly but don’t overwater—it loves humidity but hates soggy roots.
- Fertilize every 4–6 weeks for better yield.
- Harvest when fully colored (red, green, or yellow).
Once matured, store them fresh or dry them for later use. Bonus: They make great natural insect repellents!
