Today is National Hot Sauce Day. It celebrates the birthday in 1865 of Wilbur Scoville, who created a method to determine a pepper’s spiciness that is still in use today.

Scoville, an American chemist, devised the system in 1912. It measures the concentration of capsaicin, the active component that gives chilies their spicy taste, using Scoville Heat Units (SHU). Ratings range from 0 for a bell pepper to 16,000,000 for pure capsaicin.

Capsaicin content, which causes a burning sensation when it comes in contact with any tissue, is measured by dissolving a pepper in alcohol to extract its capsaicin oil, then diluting the oil in sugar water.

If a panel of five testers detects any spiciness, the mixture is diluted again until three of the five cannot discern any hotness. Heat level is measured by how many dilutions are necessary. Every instance increases the SHU, since hotter chillies must be weakened many times for no heat to be detected.

Since 2013, The Guinness World Record holder for hottest chili pepper is the Carolina Reaper, a cross between a ghost pepper and a red habanero. The Reaper’s official heat level is 1,569,300 SHU. (By comparison, Tabasco Sauce has a level 0f 2,500 to 5,000.)

Studies have shown that heat levels evoke the same pain response in spice lovers and haters and everyone in between. So why do so many of us like it? Could it predict other risk-taking behaviors? Check out this TED Ed lesson for answers.

Happy National Hot Sauce Day!
