The Science Behind Pepper Spice

The spiciness of peppers comes from a compound called capsaicin. Found mostly in the seeds and inner ribs of the fruit, capsaicin binds to pain receptors in your mouth, tricking your brain into thinking it's being burned—even though no actual fire is involved.

Scientists measure spiciness using the Scoville scale, which rates how much capsaicin is present. Bell peppers (yes, even green ones) usually fall around zero Scoville Heat Units (SHU), meaning they’re mild or non-spicy. But not all green peppers are bell peppers, and that’s where things get interesting.

Capsaicin Facts:

  • It’s fat-soluble, so milk or yogurt help ease the burn better than water.
  • Higher capsaicin levels = more intense heat.
  • Some green chilies can be hotter than fully ripe red ones.

Are Green Peppers Spicy? The Short Answer

Most green bell peppers are not spicy. They lack capsaicin, especially in the outer flesh. However, other types of green peppers, such as jalapeños, serranos, and poblanos, definitely bring the heat.

Type of Green Pepper Typical SHU Range Spicy?
Green Bell Pepper 0–100 SHU No
Jalapeño 2,500–8,000 SHU Yes
Serrano 10,000–23,000 SHU Yes
Poblano 1,000–2,000 SHU Mild to Moderate
Hatch Green Chile 1,000–30,000 SHU Variety Dependent

So when someone asks, “Are green peppers spicy?” the correct response is, “Which one?” because it all depends on the variety.

Green vs. Red, Yellow & Orange Peppers: What’s the Difference?

Green peppers are simply unripe versions of red, orange, or yellow peppers. As peppers mature, they change color and often develop more sugar, giving them a sweeter flavor profile.

Feature Green Pepper Red/Yellow/Orange Pepper
Heat Level Varies by type Generally milder (but not always)
Flavor Grassy, vegetal Sweeter, fruity
Nutrition Lower in vitamin C and beta-carotene Higher in antioxidants and vitamins
Price Usually cheaper More expensive

Fun Fact:

A red bell pepper starts its life as a green bell pepper. So technically, green peppers aren’t a different species—they’re just younger versions of the same plant!

What Factors Affect Pepper Spiciness?

You might be surprised to learn that several factors influence how spicy a green pepper can be:

  • Maturity: The longer a pepper stays on the vine, the spicier it becomes.
  • Climate: Hotter weather increases capsaicin production.
  • Stress: Peppers grown in drought or nutrient-poor soil tend to be spicier.
  • Variety: Some cultivars are bred specifically for heat, while others are bred for flavor or sweetness.
  • Seed placement: Seeds and ribs contain the most capsaicin. Remove them to reduce heat.

Spice Tips: From Mild to Wild

  • Try poblano or Anaheim peppers
  • Keep some seeds for extra kick

For the Bold & Brave:
