Are those naga jolokia? I haven’t grown them in a few years, they may not be the hottest anymore but they were so flavorful.
These are called Death Spirals because of the ridges that circle the pepper from top to bottom. They were first bred in England and are over 1 million SHU like the Naga. Once you get up to that level what's hottest is not really relevant anymore. They're all hot and how hot depends on the conditions you grow them in. Growing superhots is one of my hobbies and I am in the equivalent of hardiness zone 10B, similar to central Florida, so I can play with them almost year round. We have 2 terraces and I claim the lower one for my plants
