Bred as a hybrid in 2013 by 'Smokin' Ed Currie in South Carolina, the Reaper reaches 2.2 million Scoville units on the scientific scale used to measure the capacity of an edible substance to The Scoville scale rates the spiciness of peppers through the measurement of capsaicin levels. Created by Wilbur Scoville, the unit of measurement is the Scoville Heat Unit (SHU), and peppers range from 0 SHUs (bell pepper) to over 2 million SHUs (Carolina Reaper).. There are thousands of different pepper varieties around the world, with more being created every year through plant breeding. The Hot Sauce Scoville Scale lists numerous hot sauces sorted by their pungency and their amount of capsaicin in Scoville Heat Units (SHU). A hot sauce, also known as chili pepper sauce is a spicy seasoning sauce made from chili peppers and other ingredients such as various fruit and vegetables, vinegar and spices. 1,000,000 to 1,500,000 Scoville Units includes Trinidad Scorpion Butch T, Naga Viper, 7 Pot Primo. 1,000,000 to 2,500,000 Scoville Units includes Trinidad Moruga Scorpion, 7 Pot Douglah and the World Record Holder the Carolina Reaper. 16,000,000+ Scoville Units is Pure Capsaicin. Here are some of the hot chili peppers on the scale, measured in Scoville Heat Units (SHU): Pepper X: 2,693,000 SHU; Carolina Reaper: 2,200,000 SHU; Trinidad Moruga Scorpion: 2,009,231 SHU; Naga Viper: 1,359,000 SHU; Bhut Jolokia or Ghost Pepper: 1,041,427 SHU; Red Savina Habanero: 577,000 SHU The Puckerbutt Pepper Company - the makers of the well known Carolina Reaper - have another trick up their super-hot sleeve. Pepper X can be nearly double the heat of the mildest Reaper and a hefty 493,000 Scoville heat units hotter than the Reaper at its max spiciness. This is crazy heat. The Scoville scale. Wilbur Scoville, a pharmacologist, invented the Scoville scale in 1912 to measure the pungency of peppers and chillies, generally related to their capsaicin content. To establish a chilli pepper's rating, Scoville would prepare it in a solution, which was then tested by five people. He increased its dilution until the Chili Pepper Varieties Most Popular Peppers Free Printable Hot Pepper Chart and Remedy Sheet What is the Scoville Scale? Wilbur Scoville, a scientist in 1912, developed the Scoville scale to measure the heat of chile peppers. The calculation is based on how much sugar water it would take to neutralize the spiciness of a pepper. Carolina Reaper's range from 1,400,000 Scoville heat units to a blistering 2,200,000. That top end is just as hot as or hotter than standard pepper spray. And comparing it to a jalapeño is just silly. Even the hottest jalapeño will come in at around 175 times weaker than the mildest Carolina Reaper. 3LUe7X.
