Dorset Naga
Dorset Naga (Capsicum chinensis) is a subspecies of the original Naga, selected from the Bangladeshi varieties of the chili, naga morich.
Annually, since 2005, the heat level of Dorset Naga has been tested, taking samples from different sites, various seasons and states of maturity. The heat level has ranged from 661,451 SHU for green fruit in 2007, up to 1,032,310 SHU for ripe fruit harvested in 2009.
High as the results were, the BBC's Gardeners' World television programme recorded a much higher heat level for Dorset Naga. As part of the 2006 programming, the BBC gardening team ran a trial looking at several chili varieties, including Dorset Naga. Heat levels were tested by Warwick HRI and the Dorset Naga came in at 1,598,227 SHU, one of the hottest heat levels ever recorded for a chili.
