The Red Savina pepper is a cultivar of the habanero chili (Capsicum chinense Jacquin), which has been selectively bred to produce spicier, heavier, and larger fruit, ultimately more potent than its derivative.

[citation needed] Red Savina peppers were reported to allegedly score upwards of 577,000 on the Scoville scale, but this oft-quoted figure was never officially verified;[1] a group of researchers – including Regents Professor Paul W. Bosland at the Chile Pepper Institute at New Mexico State University – conducted a comparison experiment in 2005, which revealed that the Red Savina habanero averages a relative heat level of 248,556 SHUs.

The CPI lists the spiciest Red Savina individuals recorded in their labs as approximately 500,000 SHUs.

The average bhut jolokia is 1,019,687 SHUs, and "blasted past" the Red Savina by a factor of 2 to emerge as the temporary title-holder.

[8][9] However, the current Guinness World Record title-holder (as of August 2023), the Pepper X, has scored a maximum value of 2,693,000 SHUs.
