Pepper X – 2,693,000 SHU (Average)
Pepper X currently holds the Guinness World Record for the hottest chilli pepper, with an officially measured average of 2,693,000 SHU. Developed by Ed Currie, the creator of the Carolina Reaper, it was bred over many years for exceptional heat. Pepper X is used mainly in specialist superhot sauces and should be handled with extreme care.
Carolina Reaper – 1,641,183 to 2,200,000 SHU
The Carolina Reaper held the Guinness World Record from 2013 until Pepper X was recognised in 2023. Also developed by Ed Currie in South Carolina, it combines overwhelming heat with a surprisingly fruity, slightly sweet flavour. It is widely used in superhot sauces, powders and specialist recipes, always in very small quantities.
Trinidad Moruga Scorpion – 1,200,000 to 2,009,231 SHU
Native to Moruga in Trinidad and Tobago, the Trinidad Moruga Scorpion is one of the best-known Caribbean superhot peppers. Beneath its intense, gradually building burn lies a fruity sweetness that works well in carefully measured hot sauces and marinades. Gloves and strict portion control are essential when handling it.
7 Pot Douglah – 923,000 to 1,853,000 SHU
The 7 Pot Douglah comes from Trinidad and is recognised by its dark brown, almost chocolate-coloured pods. Its name reflects the traditional claim that one pepper can heat seven pots of food. Alongside its formidable burn, it offers earthy, fruity and slightly smoky notes that make it valuable in complex Caribbean-style sauces.
Komodo Dragon Pepper – Up to 1,500,000 SHU
Developed in the United Kingdom by grower Salvatore Genovese, the Komodo Dragon is famous for its delayed heat. Its fruity flavour arrives first, followed by a burn that continues to build. With heat reported at up to around 1,500,000 SHU, it belongs firmly in the superhot category and requires careful handling.
Naga Viper – Approximately 900,000 to 1,380,000 SHU
The Naga Viper was developed in the United Kingdom by Gerald Fowler as a hybrid associated with Bhut Jolokia, Naga Morich and Trinidad Scorpion lines. It briefly held a world heat record and is known for an intense, lingering burn with fruity undertones. Its heat can vary considerably between pods and growing conditions.
Ghost Pepper (Bhut Jolokia) – Approximately 800,000 to 1,041,000 SHU
The Ghost Pepper, or Bhut Jolokia, originates in north-eastern India and was one of the first chillies to break the one-million-SHU barrier. It delivers a slow, powerful burn accompanied by smoky, fruity and slightly sweet notes. It is traditionally used in regional cooking, but only a very small amount is needed.
Red Savina Habanero – Up to Around 500,000 SHU
The Red Savina is a selectively bred Habanero cultivar developed by Frank Garcia in California. It held the world record before the rise of later superhots. Bright red and intensely aromatic, it combines classic Habanero fruitiness with far greater heat than an everyday chilli.
Tabasco Pepper – 30,000 to 50,000 SHU
The Tabasco pepper is a Capsicum frutescens variety closely associated with the famous fermented sauce. At 30,000–50,000 SHU, it is hot but far more approachable than the superhots above. Its juicy pods and clean, sharp flavour work especially well in fermented sauces, vinegar-based condiments and everyday cooking.
Jalapeño Pepper – 2,500 to 8,000 SHU
The Jalapeño is the most accessible pepper on this list. Named after Xalapa in Veracruz, Mexico, it is used fresh, pickled, stuffed, smoked as Chipotle, or added to salsas, salads and pizza. Its moderate heat and fresh green flavour make it an excellent starting point for anyone exploring spicy food.
