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

Whether you love a little zing or want to bring the fire, here’s how to dial in your desired spice level:

For Mild Lovers:

• Stick with green bell peppers
• Remove seeds and inner membranes
• Use dairy to balance any accidental heat

For Medium Fire:

• Try poblano or Anaheim peppers
• Keep some seeds for extra kick
• Add a splash of lime or citrus to enhance flavor

For the Bold & Brave:

• Go for green serranos or Hatch chiles
• Leave the seeds and ribs in
• Pair with bold flavors like smoked paprika or chipotle
