Chile Pepper Institute studies what's hot - USATODAY.com
In February, the institute proclaimed the Moruga Scorpion the hottest chile pepper in the world, and already, the title has proven a draw for chile enthusiasts and the spice industry. Hard has created a salsa and hot sauce using the pepper, and the institute has sold out of seeds.
For the study, Bosland and his team planted several super-hot varieties of chile peppers, including the Moruga Scorpion and Scorpion, native to Trinidad; the 7 Pot and the Chocolate 7 Pot, hailing from Tobago; and the Bhut Jolokia, found in Assam, India. Ground-up samples of each variety were run through a high-performance liquid chromatography machine that counted capsaicinoids, the heat-causing chemical compound unique to chile peppers. A mathematical formula was then used to generate a number in Scoville heat units (SHU), which translates to heat intensity.
The Moruga Scorpion rated up to 2 million SHU, unseating Bhut Jolokia, which can be as hot as 1.58 million SHU.
