The Naga Viper pepper is one of the hottest chili peppers ever measured. It was briefly the "World's Hottest Chilli" in 2011 according to the Guinness World Records with a rating of 1,382,118 Scoville Heat Units (SHU), a figure that surpassed the reading of the Infinity Chilli. The Naga Viper has since been exceeded by the 2,200,000 SHU Carolina Reaper. In comparison, a jalapeno pepper measures between 2,500 and 8,000 SHU on the same scale.
