The Scoville scale is a measurement of pungency of chili peppers and other substances, recorded in Scoville heat units (SHU). It is based on the concentration of capsaicinoids, among which capsaicin is the predominant component.
Chili peppers, also spelled chile or chilli, are varieties of the berry-fruit of plants from the genus Capsicum, which are members of the nightshade family Solanaceae, cultivated for their pungency. Chili peppers are widely used in many cuisines as a spice to add "heat" to dishes. Capsaicin and related compounds known as capsaicinoids are the substances giving chili peppers their intensity when ingested or applied topically. Chili peppers exhibit a wide range of heat and flavor profiles. This diversity is the reason behind the availability of different types of paprika and chili powder, each offering its distinctive taste and heat level.
Hot sauce is a type of condiment, seasoning, or salsa made from chili peppers and other ingredients. Many commercial varieties of mass-produced hot sauce exist.
Capsicum chinense, commonly known as a "habanero-type pepper", is a species of chili pepper native to the Americas.

The hottest peppers in the world are members of this species, with a Scoville Heat Unit score of 2.69 million measured in the C. chinense cultivar, Pepper X in 2023.
The Red Savina pepper is a cultivar of the habanero chili, which has been selectively bred to produce spicier, heavier, and larger fruit, ultimately more potent than its derivative.

The Naga Viper pepper is a hot chili pepper. In 2011, it was recorded as the "World's Hottest Chili" by the Guinness World Records with a rating of 1,382,118 Scoville heat units (SHU), but was surpassed in SHU by the Carolina Reaper, in 2017, and again by the latest world record holder Pepper X in 2023.
The Infinity Chili pepper is a chili pepper hybrid of the Capsicum chinense species created in England by chili breeder Nicholas Woods of Fire Foods, Grantham, Lincolnshire.

On March 1, 2011, it was displaced by the Trinidad Scorpion Butch T pepper, which registered 1,463,700 SHU.
The Trinidad Scorpion Butch T is a Capsicum chinense cultivar that is among the hottest peppers in the world. It is a hybrid pepper and thus not indigenous to anywhere; however, its hybrid parentage is derived from the Trinidad Moruga scorpion indigenous to Trinidad and Tobago., It was named by Neil Smith from The Hippy Seed Company, after he got the seeds originally from Butch Taylor who is responsible for propagating the pepper's seeds. The "scorpion" peppers are referred to as such because the pointed end of the pepper is said to resemble a scorpion's stinger.
The Trinidad Moruga scorpion is a chili pepper native to the village of Moruga, Trinidad and Tobago. In 2012, New Mexico State University's Chile Pepper Institute identified the Trinidad Moruga scorpion as the hottest chili at that time, with heat of 1.2 million Scoville heat units (SHUs).
The Carolina Reaper chili pepper is a cultivar of the Capsicum chinense plant. Developed by American breeder Ed Currie, the pepper is red and gnarled, with a bumpy texture and small pointed tail. It was the hottest chili pepper in the world according to Guinness World Records from 2013 to 2023 before it was surpassed by Pepper X, which was also developed by Currie.

Dragon's Breath is a chili pepper cultivar that unofficially tested at 2.48 million Scoville units.
Especially among growers in the US, the UK, and Australia, there has been a competition since the 1990s to grow the hottest chili pepper.
