The Science of Spice
Pepper heat is measured in Scoville Heat Units (SHU), a scale developed by pharmacist Wilbur Scoville in 1912. The scale quantifies the concentration of capsaicin — the chemical compound that triggers the burning sensation on your tongue and releases endorphins.
Modern testing uses High-Performance Liquid Chromatography (HPLC) for precise capsaicin measurement, converting results to Scoville units. Heat can vary significantly within the same variety depending on growing conditions, soil, climate, and ripeness at harvest.
