What it is

Pharmacist Wilbur Scoville devised in 1912, at the Parke-Davis company laboratory, the 'Scoville organoleptic test', a method to quantify chili pepper heat by diluting their extract in sugar water until a panel of tasters no longer perceived burning, giving rise to Scoville Heat Units (SHU).

The original method relied on the subjective judgment of human tasters; today it is complemented by HPLC, though results are still expressed in Scoville units by tradition.

What it led to

  • standardization of heat measurement in the food and pharmaceutical industries
  • comparative classification of chili pepper varieties
  • gradual replacement by more objective instrumental methods such as HPLC
