Omri,
Even Joy owner of Dorset Naga said on the email to me that they are not confident with the testing of 1.6M SHU at all. She said her Dorset Naga has never test over 1M SHU. If you stress the hot pepper plant such as not water plant enough,etc.., it will increase the hotness on the pods. I think that is the case for Savinas. Do I trust the testing of Dorset Naga from Warwick HRI?? I definitely do not believe their testing. There is no way it increased from 960000 to 1.6M SHU without stress the plant or unconventional testing ( not the same standard of SHU ).
