The Scoville Scale is a measure of the heat from a chile pepper. The scale was named after its creator, Wilbur Scoville. 

The Scoville Scale measures the capsaicin content in a chile pepper. Capsaicin is the chemical compound that makes peppers hot. The hotter the pepper, the more capsaicin it contains.

What Does SHU Stand For

The heat in peppers is caused by capsaicin, a compound that stimulates the nerve endings in the skin.


The higher the concentration of capsaicin, the hotter the pepper will be. Peppers are rated on the Scoville Scale in Scoville Heat Units (SHU).


The scale ranges from 0 (for a pepper with no capsaicin) to 16,000,000 (for pure capsaicin). 

What is Capsaicin

Capsaicin is an active component of chili peppers, and is the substance that makes them hot. It is a member of a class of compounds known as vanilloids, which are characterized by their ability to cause a burning sensation.


When capsaicin comes into contact with human skin, it activates a protein known as TRPV1, which is responsible for the sensation of pain and heat.
