The Naga Viper is an unstable three-way hybrid superhot chili created in England that briefly held the Guinness World Record as the world's hottest pepper in 2011 at 1,382,118 SHU.

Developed by Gerald Fowler of the Chilli Pepper Company in Cark, Cumbria, the Naga Viper is a cross between the Bhut Jolokia (ghost pepper), Naga Morich, and Trinidad Scorpion (or Trinidad Moruga Scorpion). It produces elongated, wrinkled pods 2 to 3.5 inches long that ripen to a vibrant bright red and may feature a pointed scorpion-like tail. The heat is intense and slow-building, combining the fiery punch of its scorpion and naga parents with the lingering burn of the ghost pepper, delivering sweet, fruity, tangy, and citrus notes before the full intensity hits. Plants are compact, growing knee-high to 3-4 feet tall with high yields after 100-110 days. Primarily used in extreme hot sauces, rubs, and powders where a tiny amount delivers massive heat and flavor. It is not a stable variety, so individual plants and pods can vary. Handling requires gloves and caution due to potent capsaicin oils.
