The Red Savina pepper is a cultivar of the habanero chile (Capsicum chinense Jacquin), which has been selectively bred to produce hotter, heavier, and larger peppers. It is also commonly known as the Dominican Devil's Tongue Pepper or the Ball of Fire Pepper in Guyana. Samples of Red Savina have been measured as high as 577,000 Scoville units, however many chilli enthusiasts growing the Red Savina have been unable to reach this level of heat, even with certified Red Savina seed. The Chile Pepper Institute at New Mexico State University in Las Cruces, New Mexico, conducted an extensive field trial to test the Red Savina. In this scientific growth trial the Red Savina was unable to reach 250,000 scoville units. In February 2007 the Red Savina chili was displaced in Guinness World Records as the hottest chili in the world by the Naga Jolokia pepper. The Red Savina held the record from 1994 until 2006.
