The Naga Viper is the latest claimant to the world's-hottest-pepper title, beating its predecessor, the Bhoot Jolokia by more than 300,000 Scoville units of tongue-scorching chili hotness. Researchers at Warwick University testing the Naga Viper found that it measures 1,359,000 on the Scoville scale, which rates heat by tracking the presence of a chemical compound. In comparison, most varieties of jalapeño peppers measure in the 2,500 to 5,000 range. Bhoot Jolokia scored 1,000,000 Scoville units.  But Naga Viper is not a produce of Nagaland. The new pepper is actually a creation of Gerald Fowler, a British chili farmer and pub owner, who crossed three of the hottest peppers known to man, including the Bhoot Jolokia.
