[an error occurred while processing this directive] The original Scoville scale was set up in the mid 1920s and developed by Wilbur Scoville as the dilution in sugar water required for a group of trained tasters to just barely perceive (as a panel) the heat of a chile preparation. The Scoville rating today is obtained by high pressure liquid chromatography, and is NOT a subjective measurement. The Scoville measurement is an actual scientific measurement of the amount of capsaicin contained in the pepper. Note that although there are at least 5 kinds of capsaicin (or capsaicinoids) contained in a pepper, the liquid chromatography measures these all at once.
